Multi-Objective Joint Optimal Operation of Reservoir System and Analysis of Objectives Competition Mechanism: A Case Study in the Upper Reach of the Yangtze River
Authors: Chen Mufeng , Dong Zengchuan , Jia Wenhao , Ni Xiaokuan , Yao Hongyi
Published: December 2019

The multi-objective optimal operation and the joint scheduling of giant-scale reservoir systems are of great significance for water resource management; the interactions and mechanisms between the objectives are the key points. Taking the reservoir system composed of 30 reservoirs in the upper reaches of the Yangtze River as the research object, this paper constructs a multi-objective optimal operation model integrating four objectives of power generation, ecology, water supply, and shipping under the constraints of flood control to analyze the inside interaction mechanisms among the objectives. The results are as follows. (1) Compared with single power generation optimization, multi-objective optimization improves the benefits of the system. The total power generation is reduced by only 4.09% at most, but the water supply, ecology, and shipping targets are increased by 98.52%, 35.09%, and 100% at most under different inflow conditions, respectively. (2) The competition between power generation and the other targets is the most obvious; the relationship between water supply and ecology depends on the magnitude of flow required by the control section for both targets, and the restriction effect of the shipping target is limited. (3) Joint operation has greatly increased the overall benefits. Compared with the separate operation of each basin, the benefits of power generation, water supply, ecology, and shipping increased by 5.50%, 45.99%, 98.49%, and 100.00% respectively in the equilibrium scheme. This study provides a widely used method to analyze the multi-objective relationship mechanism, and can be used to guide the actual scheduling rules.

Published: December 2019

Green infrastructure is an increasingly popular approach to mitigate widespread degradation of urban waters from stormwater pollution. However, many stormwater best management practices (BMPs) have inconsistent water quality performance and are limited to on-site, land-based deployments. To address basin-wide pollutant loads still reaching urban streams, hyporheic zone engineering has been proposed as an in-stream treatment strategy. Recognizing that regulator and practitioner perspectives are essential for innovation in the water sector, we interviewed U.S. water management professionals about the perceived risks, opportunities, and knowledge gaps related to in-stream stormwater treatment. We used engineered hyporheic zones as a case study to understand interviewee perspectives on an emerging class of in-stream treatment technologies. Interviews revealed that many considerations for in-stream stormwater treatment are common to land-based BMPs, but in-stream BMPs have additional unique design and siting requirements. Here, we synthesize practitioner goals, their recommendations on in-stream BMP design, and open research questions related to in-stream BMPs. Many interviewees suggested pairing engineered hyporheic zones with other BMPs in a treatment train to improve in-stream treatment, while simultaneously reducing risk and cost. We discuss how treatment trains and other strategies might also help overcome regulatory hurdles for innovative stormwater treatment.
Spatial Distribution and Ecological Risk Assessment of Potentially Harmful Trace Elements in Surface Sediments from Lake Dali, North China
Authors: Xu Min , Sun Weiwei , Wang Rong
Published: December 2019

Potentially harmful trace element (PHTE) pollution in lakes has important implications for regional management in North China, yet is seldom investigated. Surface sediments from 13 sites in Lake Dali were collected for PHTE analysis. Combined with the enrichment factor, potential ecological risk index, and multivariate statistical analysis, the spatial distribution and ecological risk of the pollutants were studied. The results showed that the contamination levels of As, Cd, Cr, Cu, Ni, Pb, and Zn were minor to moderate. Cd, Cr, Cu, Ni, Zn, and part of Pb pollution were mainly attributed to atmospheric deposition with the development of industry in North China, and As pollution resulted from the agricultural use of chemical fertilizers and As-containing pesticides. For the overall lake, the southwest part requires the most management, and targeted measures should be tailored to mitigate the ecological risk of PHTE pollution.
Evidence of ⟨a + c⟩ dislocations in synthetic quartz single crystals compressed along the c axis
Authors: Trépied Louis , Doukhan Jean-Claude
Published: December 2019

When compressed along the c axis, quartz single crystals can accomodate deformation either by pure climb of ⟨c⟩ and ⟨a⟩ dislocations or by glide of ⟨c + a⟩ dislocations in rhombohedral and pyramidal planes {10[-1]1}, {11[-2]2} and {10[-1]1}. Detailled TEM investigations on samples deformed at high temperature clearly show ⟨c + a⟩ dislocations lying in {10[-1]1} and {11[-2]2} planes. The various possible mechanisms (climb versus glide) for this orientation are discussed.
Étude d'un sous˗joint de dislocations dans l'olivine naturelle

Published: December 2019

Un sous-joint de dislocations coin de vecteur de Burgers [100] est étudié en détail par microscopie électronique en transmission dans l'olivine naturelle. L'interaction d'une dislocation extrinsèque à la paroi de vecteur de Burgers [001] est observée en champ clair et par la méthode du contraste en faisceau faible. La réaction conduit à une dislocation de vecteur de Burgers inhabituel b = [10(-1)] qui serait dissociée et formerait ainsi un verrou au sein de la paroi. Les conséquences de cette configuration sur la plasticité de l'olivine sont envisagées.

Published: December 2019

Des dykes et des coulées de rhyolite sodique riche en fer (4,5 % de fer total en Fe₂O₃ pour SiO₂ = 72 %), à fayalite + ferroaugite ± ferropigeonite ± ferrohypersthène + titanomagnétite + oligoclase˗andésine + cristobalite + verre, sont décrits dans l'île de Sainte-Lucie. Ils sont associés à des coulées dacitiques et des hyaloclastites. L'âge K-Ar de ces formations, d'environ 8,5 M.A., ne correspond à aucune phase éruptive antérieurement connue dans l'île. On montre par l'étude des éléments en traces que ces laves acides et ferrifères, exceptionnelles en contexte orogénique, dérivent vraisemblablement de la différenciation de basaltes tholéiitiques d'arc insulaire.
Les agrafes de ceinture ajourées à Ensérune, étude et comparaisons interrégionales
Authors: Leconte Sylvie
Published: December 2019

The perforated belt-hooks of Ensérune, study and comparisons.

An important set of perforated belt-hooks has been found at Ensérune (Hérault), which is situated at a crossroad of earthly and maritime roads. The morphological study of these belt-hooks allowed the elaboration of a typology including about ten types. The stylistical analysis of this typology points out chiefly two patterns of Oriental origin “the Master of animals” and the “Tree of life”, but this interpretation must be considered very cautiously because of the very abstract feature of the patterns. The few chronological items we have lead to a dating in the IVth/IIIrd centuries B.C., this phenomenon is quite late compared to what happens in Champagne and the North of Italy. Some pieces, which are directly derived from champenois or Italian patterns seem to be older. The chief characteristic of these products of Ensérune is a local adaptation of imported patterns and local creations which are completely original.

Selective Electrochemical Reduction of Nitrogen to Ammonia by Adjusting the Three-Phase Interface
Authors: Wang Haiyan , Chen Yuzhuo , Fan Ruxue , Chen Jiadong , Wang Zhe , Mao Shanjun , Wang Yong
Published: December 2019

The electrochemical nitrogen reduction reaction (NRR) provides a sustainable and alternative avenue to the Haber-Bosch process for ammonia (NH
3
) synthesis. Despite the great efforts made on catalysts and electrolytes, unfortunately, current NRR suffers from low selectivity due to the overwhelming competition with the hydrogen evolution reaction (HER). Here, we present an adjusted three-phase interface to enhance nitrogen (N
2
) coverage on a catalyst surface and achieve a record-high Faradic efficiency (FE) up to 97% in aqueous solution. The almost entirely suppressed HER process combined with the enhanced NRR activity, benefiting from the efficient three-interface contact line, is responsible for the excellent selectivity toward NH
3
, as evidenced by the theoretical and experimental results. Our strategy also demonstrates the applicability to other catalysts that feature strong H adsorption ability, to boost the FE for NH
3
synthesis above 90% and to improve the NRR activity by engineering the catalysts.

Educational Technology is an applied study which aims at maximizing learning by making use of the scientific and technological method and concepts developed in other social service. “Educational technology is the application of scientific knowledge about learning and conditions learning to improve the effectiveness and efficiency of teaching and learning.”Four Pillars of Flipped Learning Flipped Learning Consists Of Four Pillars: Flexible Environment, learning the culture, intentional content, and Professional educators. Flipped Learning F-L-I-PFlexible Environment Learning Culture Intentional Content Professional Educators. Flipping a classroom is one of the recent methods which requires teachers’ recording the lesson and students’ watching the recordings before coming to the classroom to spend the class time with the activities. As teachers do not deliver the lecture in the class, more time can be allocated to active learning activities. The flipped classroom is “a teaching method that delivers lecture content to students at home through electronic means and uses class time for practical application activities, may be useful for information literacy instruction.” That means that there is much more use of technology for Flipped Learning. The objectives of the study were: to study the effectiveness of Flipped classroom instruction upon the teaching of Chemistry at the Higher secondary level. Findings: The means of pre-test scores and post-test scores of experimental groups differ significantly (0.01 level) with the post-test mean being higher than the pretest mean. The implication of that is that the level of acquiring of the basic skills in Chemistry has not increased due to the traditional method in the Control group and the Flipped classroomInstructional Method in Experimental group. The post-test scores of the control and experimental group differ significantly. The means score of the experimental group is greater than of the control group.

Published: December 2019

In Bangladesh, private university sectors have observed several modifications with the initiation of Communicative Language Teaching (CLT). The communicative approach is expected to form such an ambience in the language classrooms where anxiety, fear and boredom are minimized and students are not under the influence of the affective factors in a tertiary level. This paper intends to explore the reasons that the students' background and affective factors affect highly on the speaking skills of the undergraduate level learners and it aims to find the solutions to these problems from the students’ perspectives. To collect the data, researchers used a questionnaire to specify major problems faced by the tertiary level learners in speaking English and strategies to overcome those from their viewpoints. The survey shows, in many cases, anxiety, fear and hesitation and performance pressure hinders the speaking of individuals, whereas, if the speaking situation is friendly and provide a platform to uninterrupted speaking with constructive feedback, it may facilitate learners speaking. In the end, analyzing the results, the researchers have discussed some effective solutions from their experiences to overcome these affective states among adult learners.

A review study on ladle slag detection technologies in continuous casting process
Authors: KAPUSUZ Hakan , GÜVENÇ Mehmet Ali , MISTIKOĞLU Selçuk
Published: December 2019

In
steel production, continuous casting method using BOF or EAF is increasing day
by day. However, the complex nature of the continuous casting process poses
many challenges for steelmakers. During the general steel production process of
liquid steel, the state of ladle slag penetration into liquid steel is one of
the most influential factors in steel quality. If the ingress of ladle slag
into liquid steel cannot be controlled, undesirable results in terms of poor
quality, safety and castability can occur. Generally, ladle slag consists of
oxides such as CaO, SiO 2, Al 2 O 3, MgO. In conventional methods, the operator
prevents the slag entry by manually controlling it. This method is performed
directly by the operator, so the error rate is high. For this reason, it is not
desired to be used by steel producers who want high quality products. In this
context, steel mills carry out various activities to separate slag from liquid
steel. The development of sensor technologies has accelerated the slag
detection process. Acceleration and magnetic sensors are among the most widely
used methods in this field. In this study,
the systems used worldwide for the determination of slag in the continuous
casting process were investigated and presented. The advantages and disadvantages
of these systems are discussed. The detection methods by considering investment
cost, detection time, accuracy were compared and presented. In the scope of
this study, it is seen that every method has own advantages and disadvantages
over other.

Addressing Flooding Attacks in IPv6-based Low Power and Lossy Networks
Authors: Verma Abhishek , Ranga Virender
Published: December 2019

Abstarct: In the RPL routing protocol, DODAG Information

Solicitation (DIS) control messages are sent by nodes to join the network. In turn, the receiver node replies with DODAG Information Object (DIO) control message after resetting its trickle timer. A malicious node can utilize this RPL protocol behavior to perform the DIS flooding attack by sending illegitimate DIS frequently which forces normal nodes to reset their trickle timers and flood the network with DIO messages. In this study, we show that such attacks can severely degrade the performance of Low Power and Lossy Networks (LLNs) because of the increase in control packet overhead and power consumption. To address DIS flooding attacks, we propose a lightweight mitigation scheme that detects and mitigate such attacks in order to improve LLNs

performance.

xAbstract—In this paper, the physical layer security of a dualhop

underlay uplink cognitive radio network is investigated over

Nakagami-m fading channels. Specifically, multiple secondary

sources are taking turns in accessing the licensed

spectrum of the primary users and communicating with a multiantenna

secondary base station (D) through the aid of a multiantenna

relay R in the presence of M eavesdroppers

that are also equipped with multiple antennas. Among the

remaining nodes, one jammer is randomly selected to transmit

an artificial noise to disrupt all the eavesdroppers that are

attempting to intercept the communication of the legitimate links

i.e., Si -R and R-D. The received signals at each node are combined

using maximum-ratio combining. Secrecy analysis is provided by

deriving closed-form and asymptotic expressions for the secrecy

outage probability. The impact of several key parameters on the

system’s secrecy e.g., transmit power of the sources, number of

eavesdroppers, maximum tolerated interference power, and the

number of diversity branches is investigated. Importantly, by

considering two scenarios, namely (i) absence and (ii) presence

of a friendly jammer, new insights are obtained for the considered

communication system. Especially, we tend to answer to the

following question: Can better secrecy be achieved without

jamming by considering a single antenna at eavesdroppers

and multiple-ones at the legitimate users (i.e., relay and enduser)

rather than sending permanently an artificial noise and

considering that both the relay and the destination are equipped

with a single antenna, while multiple antennas are used by the

eavesdroppers? The obtained results are corroborated through

Monte Carlo simulation and show that the system’s security can

be enhanced by adjusting the aforementioned parameters.

Cowpea (Vigna unguiculata (L.) Walp.) is a culture that plays an important role in agricultural production of Brazilian states. While the culture is well researched, when referring to stages of development are little studies about. Therefore, the identification of phenological stages of crops is very important to facilitate the adoption of best management strategies to better yields and profitability. The objective of this review describe the phenological stages of cowpea cv. BR 17 - Gurguéia relating the number of degree-days (GDD) for each stage of development, indicating pests and diseases that can affect the crop. The phenology of plants has the remarkable characteristic the fact that the GDD is independent of the time and the planting site. Research has shown a greater adaptation of the cycle of some crops to GDD than the number of calendar days, and can estimate more easily cycle time, as well as establish the planting season due to the most appropriate time to harvest. The cultivar BR-17 Gurguéia has at least nine vegetative and reproductive stages having the lowest cumulative thermal demand stage V1 and reproductive stages require a greater number of degree-days compared to vegetative.

PSICOLOGIA E PASTORADO LAICO: PENSANDO AS ESTRATÉGIAS DE GOVERNO DA INFÂNCIA
Authors: Santos de Oliveira Sandra Raquel
Published: December 2019

Esse artigo é parte de uma pesquisa que tem como objetivo pensar as estratégias de cuidado e pedagógicas investidas sobre a infância que de alguma forma estão envolvidas na produção do que chamaremos de uma “cultura da mansidão”. Seguimos na espreita de que muitas práticas de cuidado e pedagógicas, envolvendo de forma privilegiada as práticas psicológicas, são acionadas no sentido de compor estrategicamente com as políticas de amansamento. A principal chave conceitual para pensar essas estratégias é a noção de pastorado de Estado/laico ou contemporâneo, uma atualização de práticas pastorais de um cristianismo ocidental moderno institucionalizado na forma-igreja em práticas orientadas por saberes qualificados como científicos e articulados a práticas de governo. Nesse sentido, a colaboração histórica da Psicologia nesses processos configura-se como uma demanda do aparecimento da sociedade moderna para legitimar os modos de existir individualizados e docilizados como dominantes, portanto, os mais próximos do que seria considerado como normal e saudável, através de táticas medicalizantes e judicializantes. Por outro lado, como campo de produção inventiva, a Psicologia pode colaborar para operar fissuras com essa lógica individualizante fartamente fortalecida pelos processos de medicalização dos chamados processos de cuidado, de aprendizagem e desenvolvimento humanos. Entretanto, parece que a transformação das práticas hegemônicas depende fundamentalmente dos lugares estratégicos que ocupamos e da maneira como ocupamos. Não se pode perder de vista a permeabilidade das funções institucionais e desses lugares de poder, entendendo- -os como os modos possíveis de efetivarmos nossas políticas.

Authors: Wirentake Wirentake
Published: December 2019

This study was aimed at investigating students’ perception of motivational teaching strategies in English as Foreign Language (EFL) classroom, specifically on what motivational teaching strategies do students consider important and what are their reasons of considering the strategies as important. This study was a descriptive qualitative study. The instruments employed were questionnaire and interview. Based on the findings, the motivational teaching strategies considered most important are: (1) establish good relationship with students; (2) teachers should bring humors into the classroom; (3) teachers should show their enthusiasm for teaching; (4) teachers should show students that they care about them; (5) teachers should give clear instruction about how to carry a task; (6) teachers should make sure that grades reflect students achievement and effort; (7) teachers should invite English-speaking foreigners to class; (8) teachers should use a short and interesting opening activity to start each class; (9) teachers should avoid social comparison and (10) teachers should be themselves in front of students. In addition, one of the common reasons of why students considered those motivational teaching strategies as important was because they believed that those strategies are able to boost their motivation in learning English if it is implemented by their teachers.
ALTERNATIF PERKUATAN LERENG PADA RUAS JALAN TRENGGALEK-PONOROGO KM 23 +650
Authors: Dharmawansyah Dedy
Published: December 2019

Pada pertengahan tahun 2010, ruas jalan Trenggalek-Ponorogo KM 23 +650 terjadi kelongsoran sepanjang ± 50 m dengan ketinggian 7 m dan mengikis hampir separuh dari badan jalan. Akibat dari kejadian tersebut arus lalu lintas disepanjang jalan tersebut terhambat. Beberapa bulan setelah kejadian, Dinas Pekerjaan Umum Bina Marga Propinsi Jawa timur melakukan perbaikan mulai dari dasar lereng sampai ketinggian 3,5 m dengan menggunakan konstruksi retaining wall dan gabion (Perkuatan eksisting) sedangkan pada separuh bagian lereng lainnya yang berada diatas perkuatan eksisting sampai badan jalan belum diperbaiki sampai saat ini. Selama masa pemakaian, konstruksi retaining wall yang terpasang sudah tidak berfungsi secara optimal; ini dibuktikan dengan terjadinya keretakan pada konstruksi tersebut yang dikuatirkan akan menyebabkan lereng longsor kembali.Dari analisa stabilitas pada lereng asli diperoleh SF sebesar 1,0888, sedangkan dengan perkuatan eksisting diperoleh SF sebesar 1,13; ini menunjukkan bahwa lereng masih dalam kondisi kritis sehingga diperlukan sistem perkuatan.

PRODUKSI DAN REPRODUKSI MEMORI: PENGALAMAN KELUARGA EKS TAHANAN POLITIK PKI DI SULAWESI SELATAN
Authors: Ahmad Taufik
Published: December 2019

Pergeseran politik dari rezim Orde Baru ke era reformasi pada dasarnya telah memberi ruang gerak lebih luas kepada eks tapol untuk mereproduksi memori trauma dalam bentuk formal. Jika era Order Baru produksi memori eks tapol hanya dalam lingkunga keluarga, maka di era reformasi mereka mentransmisikan memori ke post-memori dengan cara lebih terbuka. Artikel ini mencoba untuk melihat produksi dan reproduksi memori dengan mengambil kasus dua keluarga eks tahanan politik (Tapol) PKI di Sulawesi Selatan. Dengan menggunakan metodologi sejarah dan menekankan pada proses, studi ini membuktikan bahwa produksi memori tapol diekspresikan melalui catatan-catatan harian, surat-surat, dan sketsa. Memori tersebut kemudian ditransmisikan ke generasi post-memori melalui cerita-cerita keluarga, gambar dan prilaku seharihari. Selanjutnya, generasi post-memori mereproduksi dan menerjemahkan ulang warisan memori tersebut di tengah perubahan-perubahan sosial politik. Konteks ini mengindikasikan bahwa pada masa Orde Baru, memori eks tapol hanya menjadi bagian dari domestic memory, kemudian berubah menjadi public memory yang diartikulasikan secara terbuka di era reformasi. Akan tetapi, terdapat cara-cara yang berbeda setiap tapol dalam memproduksi dan mentransmisikan memorinya. Latar belakang eks tapol; Pendidikan, kehidupan keluarga, dan aktivitas di masa lalu, memberi pengaruh signifikan terhadap pilihan-pilihan dalam menentukan model transmisi memori.

Authors: Irwan Irwan
Published: December 2019

Penelitian ini bertujuan mengungkapkan aspek sosial budaya dalam naskah drama Sang Mandor karya Rahman Arge. Metode penelitian yang digunakan dalam mengkaji naskah drama tersebut adalah metode deskriptif kualitatif. Hasil penelitian ini menunjukkan bahwa Rahman Arge dalam naskah dramanya mengangkat budaya orang Bugis/Makassar. Sang Mandor mempunyai karakter yang begitu keras. Dalam sakitnya, sang Mandor masih ingin berlayar sebagai mandor kapal. Karakter tersebut merupakan ciri khas orang Bugis/Makassar, yakni: angkuh, bergelora, acapkali menyala, dan kadang-kadang tidak memandang apa dan siapa. Akan tetapi, orang Makassar dan Bugis dalam ketenangan dapat menerima hal yang baik dan indah. Orang Bugis/ Makassar mempunyai karakter tegas, berani, dan bersedia memikul segala konsekuensi dari setiap kata dan perbuatannya. Realita kehidupan yang digambarkan dalam naskah drama Sang Mandor karya Rahman Arge mulai pudar pada masyarakat Bugis/Makassar saat ini, nilai-nilai budaya pun mulai bergeser. Pergeseran ini disebabkan oleh pengaruh budaya luar yang masuk dalam budaya Bugis/Makassar.
