Authors: Indriani Nina , Aisyah Arum Nur , Elok Faza Nurinda
Published: March 2022

Penelitian ini bertujuan untuk mengetahui permasalahan yang disebabkan penerapan pembelajaran satu arah dalam pembelajaran matematika dan cara mengatasi permasalahan tersebut. Untuk penelitian ini menggunakan metode penelitian deksriptif kualitatif dan studi literatur. Pembelajaran satu arah adalah proses pembelajaran di mana guru lebih berperan aktif dalam menyampaikan materi pembelajaran. Kelebihan pembelajaran satu arah adalah memudahkan guru dalam menguasai kelas, cocok digunakan dalam kelas dengan jumlah peserta didik yang besar, dan mudah diterapkan. Kekurangan pembelajaran satu arah adalah pembelajaran membosankan dan tidak menarik, materi mudah terlupakan, dan peserta didik menjadi pasif. Penerapan pembelajaran satu arah pada pelaksanaan pembelajaran matematika dilakukan dengan guru langsung menyampaikan materi pembelajaran dilanjutkan dengan peserta didik diberikan soal dan diminta mengerjakan sesuai dengan cara meniru contoh yang sudah dijelaskan. Permasalahan akibat penggunaan penggunaan pembelajaran satu arah dalam pembelajaran matematika seperti interaksi antara guru dan peserta didik sangat kurang, mengutamakan hafalan, dan pembelajaran menjadi tidak bermakna. Cara mengatasi permasalahan tersebut dengan guru mengubah perannya menjadi fasilitator dan membantu mengubah pandangan peserta didiknya bahwa matematika tidak susah tetapi menyenangkan dan menarik untuk dipelajari.
Deconstructing Orientalism
Authors: Labrusse Rémi
Published: March 2022

This article has no intention to deconstruct the now classical Saidian idea that Western Orientalism was a global system of misrepresentation and control of non-Western cultures, particularly in the nineteenth century, when the colonial expansion spread over most of the regions marked by the cultures of Islam. Instead, It intends to reflect upon the fact that during this period, the Orientalist system established itself in the broader context of a modern condition which was (and still is) felt and conceived as a general “state of crisis.” This critical dimension of modern Western culture explains both the extreme degree of violence of the Orientalist enterprise of capture and its internal criticism by its own perpetrators.

The same duality characterizes the modern production of visual images: the crisis of the Western mode of mimetic representation is responsible for both the paroxysmal multiplication of images, in the nascent “society of the spectacle,” and their implosion, in the experiments of the so-called artistic avant-gardes at the beginning of the twentieth century. Some decades earlier, such a radical critique of representation had been developed at the crossroads of applied arts and architecture, in debates on the nature and function of ornaments. We know how central the reference to the arts of Islam and their aesthetics, which were conceived in opposition to the contemporary Orientalist fancies, was for these debates. How did these two positions—the critique of Orientalism and of visual representation—interact? To what extent did they reinforce each other? In order to illustrate this question, This article will conjure up a most revealing episode: Henri Matisse’s trip to Algeria in 1906 and the works that immediately followed this early “Oriental” encounter for the artist.
Islamic Geometry Reinterpreted
Authors: Keller Sarah
Published: March 2022

In the second half of the nineteenth century, there was a growing interest in Western countries for Islamic stucco glass windows, which were known from descriptions in books and as imported artifacts. Among the oldest publications is Émile Prisse d’Avennes’ (1807-1879) L’art arabe d’après les monuments du Kaire depuis le VIIe siècle jusqu’à la fin du XVIIIe. One year after its publication in 1877, its illustrations inspired the geometrical patterns of the windows of the Moroccan House, a neo-Moorish pavilion in the park of Linderhof Palace (Ettal, Germany).
Starting Point of the Arabic-Andalusi Influence in Gaudi’s Ornamental Ceramic
Authors: Freixa Mireia , Saliné Marta
Published: March 2022

Between 1884 and 1887, Antoni Gaudí built two rather modest constructions for his patron, Eusebi Güell: a stable for the horses and a porterhouse for his country house in Les Corts. In these constructions, he makes an important step in relation to his previous works, El Capricho (Comillas, Santander) and the Casa Vicenç (Barcelona). The tiles used in both, featuring lines of color that contrast with the brick and stone, derive from an original system of using ceramic, the trencadís. He takes as a reference point the Arabic or Mudejar building system to embed ceramic pieces in the walls and in the coronation railings of the buildings, but adds a brilliant contribution by converting it into “broken” ceramics. We call this ornamental resource trencadís, since trencar means broken in Catalan. This technique is one of Gaudí’s more significant decorative choices with brilliant examples of this being the façade of Casa Batlló and the dragon and banc-balustrade in Park Güell.

Authors: Mahjar Narmin T. , Al-Salhie Khalid C. K.
Published: March 2022

The objective of this study was to investigate the effect of in ovo injection of alcoholic garlic extract on hatching traits, liver enzymes, and antioxidant status of broiler chickens post-hatch. In total, 625 broiler breeder eggs (ROSS 308 strain with an average weight of 58.5 g) were divided into 5 treatments (each treatment had three replicates). At 0 embryonic day, the eggs were injected as follows: the first treatment without in ovo injection (negative control), eggs of second treatment were injected with 100 μL.egg-1 distilled water (sham control). The third, fourth, and fifth treatments were injected with 50, 100, and 150 μL.egg-1 of an alcoholic garlic extract respectively. The chicks were reared for 4 weeks after hatching according to in ovo treatments. Hatchability, embryonic mortality, chicks' weight, serum AST, ALT, GPx, SOD activities, and MDA concentration were all measured. The results showed that the hatchability of the fifth treatment was higher (P≤0.05) than those of the other treatments. On the other hand, the embryonic mortality of the fifth treatment was recorded less (P≤0.05) than those of the other treatments. The results of serum AST, ALT, GPx, SOD activities, and MDA concentration were non different significance (P>0.05) among treatments. It is concluded that a garlic extract injection with 150 μL.egg-1 improved hatchability and reduced embryonic mortality. Moreover, it did not affect the chick's weight, serum liver enzymes, and antioxidant status post-hatch.

Published: March 2022

Rice is one of the most important crops in Pakistan, grown all over the world. Rice production has decreased due to susceptibility to a number of biological and abiotic factors. One of the oldest diseases is bacterial leaf blight of rice. The causative agent of the disease is Xanthomonas oryzae pv. oryzae. In this study, seedlings of four commercially grown rice varieties were sown by following the randomized complete block design (RCBD). Four treatments were used to manage the disease and to promote the plant growth. Correlation and regression analysis was used to study the relation of BLB disease and environmental factors. It was observed that plant height increased by the application of NPK followed by Farm yard manure, boron and leaf manure. Panicle length and weight was maximum in boron treated plants while minimum in FYM. Minimum disease severity was recorded in NPK treatment followed by boron FYM and leaf manure. All the environmental variables showed significantly negative relationship with the development BLB disease. These results would be beneficial for the farming community to devise management options against BLB disease.

Authors: Krisna Fransisca Nur’aini
Published: March 2022

Salah satu permasalahan guru yang masih menjadi perhatian khusus Kementerian Pendidikan dan Kebudayaan adalah ketidakmerataan penyebaran guru. Secara nasional, meski rata-ratarasio guru SD terhadap peserta didik (1:19) lebih rendah dari standar yang ditetapkan (1:32), namun terjadi ketimpangan dalam hal penyebarannya. Begitu pun untuk tingkat SMP, meski rerata rasio guru terhadap peserta didik (1:32) cukup rendah dibandingkan standar (1:36), namun beberapa daerah mengalami kekurangan guru, sementara daerah lainnya kelebihan guru. Kajian ini mencermati beberapa kabupaten yang telah berhasil melakukan pemerataan guru di daerahnya. Metode penelitian kajian ini adalah deskriptif kualitatif dengan menganalisis data sekunder yang berasal dari berbagai sumber rujukan berupa video rekaman wawancara narasumber terkait, dokumen, peraturan perundangan, dan literatur lainnya. Strategi pemerataan guru yang dilakukan di beberapa kabupaten tersebut antara lain penggabungan dua sekolah, mutasi guru, pembelajaran kelas rangkap, guru keliling, dan pengangkatan guru baru. Analisis kebijakan dilakukan dengan menggunakan berbagai kriteria, seperti aspek efektifitas, efisiensi, aspek ketercukupan, keadilan/ pemerataan, keresponsifan, dan aspek kelayakan untuk menganalisis beberapa alternatif kebijakan yang telah dilakukan pemerintah daerah dalam pemerataan guru. Model pemerataan guru selanjutnya dikembangkan sesuai dengan kondisi tipologi daerah.

“French Teachers Can Figure It Out”: Understanding French as a Second Language (FSL) Teachers’ Work in the Context of the COVID-19 Pandemic
Authors: Smith Cameron , Arnott Stephanie
Published: March 2022

In 2020, the coronavirus (COVID-19) pandemic forced teachers in Ontario to move online. Since then, teaching online or in hybrid models has been common across the province. To understand how French as a Second Language (FSL) teachers navigated these spaces, four Ontario French teachers were interviewed about their experience using educational technology and teaching online. Findings were analyzed in light of Hargreaves and Fullan’s (2020) reframing of classic understandings of teachers’ work in the context of the global pandemic. Findings show that factors influencing these teachers’ professional capital reflect common concerns among Canadian educators, alongside those specific to the FSL context. Participants' professional marginalization and seclusion demonstrates the importance of both the psychic rewards of teaching and cultures of collaboration. Ongoing efforts to capture ways in which teaching FSL has been shaped by the pandemic experience, therefore, require looking beyond individual classrooms to connected systems and systematic efforts of reform.
The Nature of Art
Authors: Leroi Armand Marie
Published: March 2022

Can pieces of art be related to each other in the way that biological species can? In living things, phylogenic links are forged by the inheritance of genetic material; in culture, by influential ideas. Artworks may not have genomes, but they do contain information. Basic phylogenetic methodology may be applied to create a more scientific study of art history.

Authors: Xia Chen , Chu Zhigang , Jin Dongmei , Xiao Yan , Ma Wen , Cheng Maojie
Published: March 2022

While sinomenine plays a crucial anticancer role in a variety of cancers, its function and molecular mechanism in cutaneous squamous cell carcinoma remains unexplored. To this end, we explored the effect of sinomenine on cell viability, colony formation rate, cell apoptosis rate, and migration and invasion and wound healing in A431 and SCL-1 cells representing cutaneous squamous cell carcinoma. The results show that sinomenine inhibited cutaneous squamous cell carcinoma viability, clone formation, migration and invasion, induced cell apoptosis by inactivating AKT/mTOR pathway. These data may likely to provide a novel candidate for treating patients diagnosed with cutaneous squamous cell carcinoma.
Ginkgetin Inhibits the Growth of Melanoma Cells by Regulating JAK2/STAT3 Signaling Pathway
Authors: Zhuang Chuchen , Zhang Liping
Published: March 2022

Melanoma is the most invasive skin cancer with the highest risk of death. Better understanding of the pathogenesis of melanoma has helped identify new therapeutic targets and drugs against melanoma in prolonging the survival of melanoma patients. Ginkgetin is a bioflavonoid compound extracted from the leaves of Ginkgo biloba, which exhibits a multitude of biological activities such as antiviral, antioxidant, anti-inflammatory, and antifungal. Although it has been shown to suppress the progression of multiple types of tumors, its role in melanoma remains unexplored. Therefore, we investigated the role and potential mechanism of ginkgetin in melanoma. The results of the studies reported here show that ginkgetin inhibits proliferation and promotes apoptosis of the melanoma cell lines. Ginkgetin also induces G1/G0 arrest of the melanoma cells by regulating signal transducer and activator of transcription 3 and mitogen-activated protein kinase signaling pathways. We therefore believe that ginkgetin may be a promising drug in the treatment and cure of melanoma.

Published: March 2022

Gas distribution plant (GDP) is a part of gas mains performing gas intake from the gas main, its cleaning from liquid and mechanical impurities, gas heating, pressure reducing to the value set, measuring gas charge and further transportation to the consumers. The order of the implementation of technological processes is set according to the construction standards for gas main design. The order of technological processes presented often does not meet the requirements for the cleaning degree and regulation of gas pressure. With the changing of order and optimization of technological processes in GDP, i.e. with the substitution of pressure control valve for more efficient turbo expander unit, it is possible to achieve high reliability and cost effeciency in gas transportation. The method of electric energy production in this process compared to the others is ecologically safe and do not negatively affect the environment. Economical efficiency of the operation may be calculated according to the technical indexes of each GDP.

Published: March 2022

The paper presents the results of study on the pressure effect on hydrocracking process of vacuum gasoil from the mixture of Baku oils with the presence of aluminosilicate catalyst modified Ni, Mo. Hydrocracking of vacuum gasoil in the presence of aluminosilicate catalyst, modified Ni, Mo has been carried out in 3−8 MPa pressure in the temperature interval of 400−450 оС with the speed of 0.7−2.0 h-1 on Hungarian unit with reactor capacity in 200 ml. The pressure effect on the hdyrocracking process has been studied in the diapason of 3-8 MPa. It was defined that while the pressure is increasing from 3 to 5 MPa, the yield of diesel fraction also increases from 35 to 44 % mass. The pressure increase from 5 to 8 MPa increases the yield of diesel fraction for 48 %, i.e. the growth of only for 4 % is observed. It was considered practical to conduct hydrocracking process in 5MPa, as the pressure increase from 5 to 8 MPa leads to the significant increase of capital expenses.

Authors: Joshi Jagidsh , Bhatt Mahesh
Published: March 2022

Literature is one of the best mediums which can unfold various issues of the subalterns especially the issues of women. Pen is mightier than sword. In the era of globalization, migration has become inevitable for progress and sustenance. The issues of immigrant women-vis- a-vis those who are at home are of prime concern today and the expatriate women writers give voice to it.
The paper will focus on comparative study of two novels of the expatriate novelists, viz. Anita Rau Badami’s The Hero’s Walk and BapsiSidhwa’s An American Brat. It will concentrate on various issues that women face in the host country and homeland. In The Hero’s Walk, Maya goes to Canada and then marries with Alan. Her condition in a patriarchal set up and the freedom that she gets in Canada are narrated by Badami. An American Brat narrates the journey of a young woman Feroza through three cultures-her own community’s Parsi culture, her country’s Pakistani Islamic culture and the western culture of the United States. In Pakistan she finds clash between conservative Islamic traditions and freedom of her community. A comparison between gender-relations in India and among overseas Indian communities will be carried out.
The novels will be studied from the theories of Edward Said and Gaytri Spivak on legacy of
Colonialism. It will help to reassess the conventional ways of understanding the status of women and will suggest various steps that are required to be taken in social, political and economic policies for eradication of this gender discrimination and to provide a dignified status to women.

We obtained, processed, and interpreted spectral analyses of aeromagnetic data across a portion of the Lower Benue Trough with the goal of estimating the depth to magnetic basement, modeling a conspicuous magnetic anomaly, identifying the basement topography, and evaluating basin configurations. Qualitative interpretation based on visual examination of the total magnetic intensive anomalies map, residual contour map, and first vertical derivative map reveals major faults trending east-west (E-W) and minor faults trending northeast-southwest (NE-SW), which is consistent with the structure of the lower Benue Trough. The western portion of the research region indicates structural change near the towns of Afikpo and Ishiagu, indicating areas of documented intrusive igneous body activity. According to the quantitative interpretation of the aeromagmatic data, the average sedimentary thickness is between (2.3 and 3.2 kilometers) and Quantitative interpretation utilizing spectral analysis identifies two distinct depth sources in the region: shallower sources ranging from 1.09 to 1.6 kilometers in the southern portion of the research area, and deeper sources ranging from 1.61 to 4.90 kilometers in the northern section. Additionally, the research reveals that the depths to the centroid and magnetic bodies (sedimentary thicknesses) vary between 5.02 and 10.65 kilometers and 0.23 and 3.5 kilometers, respectively. It was recommended that a ground magnetic survey be used in conjunction with this work to provide a more conclusive result.

Extracting the Subhalo Mass Function from Strong Lens Images with Image Segmentation
Authors: Ostdiek Bryan , Diaz Rivero Ana , Dvorkin Cora

Detecting substructure within strongly lensed images is a promising route to shed light on the nature of dark matter. However, it is a challenging task, which traditionally requires detailed lens modeling and source reconstruction, taking weeks to analyze each system. We use machine learning to circumvent the need for lens and source modeling and develop a neural network to both locate subhalos in an image as well as determine their mass using the technique of image segmentation. The network is trained on images with a single subhalo located near the Einstein ring across a wide range of apparent source magnitudes. The network is then able to resolve subhalos with masses m ≳ 108.5
M
⊙. Training in this way allows the network to learn the gravitational lensing of light, and, remarkably, it is then able to detect entire populations of substructure, even for locations further away from the Einstein ring than those used in training. Over a wide range of the apparent source magnitude, the false-positive rate is around three false subhalos per 100 images, coming mostly from the lightest detectable subhalo for that signal-to-noise ratio. With good accuracy and a low false-positive rate, counting the number of pixels assigned to each subhalo class over multiple images allows for a measurement of the subhalo mass function (SMF). When measured over three mass bins from 109–1010
M
⊙ the SMF slope is recovered with an error of 36% for 50 images, and this improves to 10% for 1000 images with Hubble Space Telescope-like noise.

We present an Atacama Large Millimeter/submillimeter Array (ALMA) survey of CO(4–3) line emitting galaxies in 17 quasar fields at z ∼ 4 aimed at performing the first systematic search of dusty galaxies in high-z quasar environments. Our blind search of galaxies around the quasars results in five CO emitters with S/N ≥ 5.6 within a projected radius of R ≲ 1.5 h
−1 cMpc and a velocity range of δv = ±1000 km s−1 around the quasar. In blank fields, we expect to detect only 0.28 CO emitters within the same volume, implying a total overdensity of

Finally, we constrain, for the first time, the clustering of CO emitters at z ∼ 4, finding an autocorrelation length of r

−1 cMpc (with γ = 1.8). Our work, together with the previous study of LAEs around quasars, traces simultaneously the clustering properties of both optical and dusty galaxy populations in quasars fields, stressing the importance of multiwavelength studies, and highlighting important questions about galaxy properties in high-z dense environments.
Flexible and Accurate Evaluation of Gravitational-wave Malmquist Bias with Machine Learning
Authors: Talbot Colm , Thrane Eric
Published: March 2022

Many astronomical surveys are limited by the brightness of the sources, and gravitational-wave searches are no exception. The detectability of gravitational waves from merging binaries is affected by the mass and spin of the constituent compact objects. To perform unbiased inference on the distribution of compact binaries, it is necessary to account for this selection effect, which is known as Malmquist bias. Since systematic error from selection effects grows with the number of events, it will be increasingly important over the coming years to accurately estimate the observational selection function for gravitational-wave astronomy. We employ density estimation methods to accurately and efficiently compute the compact binary coalescence selection function. We introduce a simple pre-processing method, which significantly reduces the complexity of the required machine-learning models. We demonstrate that our method has smaller statistical errors at comparable computational cost than the method currently most widely used allowing us to probe narrower distributions of spin magnitudes. The currently used method leaves 10%–50% of the interesting black hole spin models inaccessible; our new method can probe >99% of the models and has a lower uncertainty for >80% of the models.
