Equilibrium of Dyeing: A Review
Authors:   Department of Textile Engineering, Wollo University, AD Wolela ,   Kombolcha, Ethiopia
Published: February 2023

This paper presents equilibrium dyeing which is important in the dyeing process. The paper gives more emphasis on the dyeing equilibrium which is the position of sorption versus desorption after infinite time. In dyeing process, the investigation of the equilibrium dye distribution between the dye bath and the substrate is very important. The thermodynamics of dyeing of different textile fibers with their respective dyes type were discussed. Furthermore the three major types of dyeing adsorption isotherms, which are Nernst, Langmuir and Freundlich and the various dye/fibre systems correspond to one of these types. The most important thermodynamic parameters such as affinity, heat of dyeing and entropy of change which is determined at equilibrium have been also discussed. These values are useful in interpreting the driving force for dyeing processes and therefore provide a means for understanding what causes dye to transfer preferentially from the dye liquor into the fibre.

Authors: Muñoz-Perales Vanesa , Ibáñez Santiago E. , García-Quismondo Enrique , Berling Sabrina , Vera Marcos
Published: February 2023

Redox flow batteries are a promising electrochemical technology for large-scale stationary energy storage. Continuous macroscopic models address the design and operational challenges required to increase their profitability and energy market penetration. Controlling the battery operating temperature and avoiding cell overheating are two primary ways to ensure optimal overall efficiency. This work presents a nonisothermal two-dimensional steady-state model of a unit-cell all-vanadium redox flow battery. The model is validated using polarization and open circuit voltage measurements at different temperatures and states of charge. After calibration, a parametric study is used to explore the role of operating temperature on cell performance, deconvoluting the different contributions to cell heating, and providing practical guidance about the thermal effects of operating conditions. The results reveal that increasing the operating temperature improves species mass transfer but negatively affects activation losses; the cell suffers higher overheating during charge than during discharge; and cell length has a proportional effect on cell heating. Lastly, we propose the use of asymmetric electrolyte temperatures as a performance improvement strategy for electrochemical storage systems hybridized with thermal energy storage. The results show that nonisothermal models are a powerful tool for optimizing advanced electrochemical flow reactors in energy storage devices.
Structural tuning of fluorinated hybrid ultramicroporous materials (HUMs) for low-concentration CO2 capture
Authors: Chang Ribooga , Åhlén Michelle , Cheung Ocean
Published: February 2023

Hybrid ultramicroprous materials (HUMs) with a number of different variations of the inorganic pillars as well as surface functional groups have been tested as CO2 sorbent for low-concentration CO2 capture. Specifically well-known HUM NbOFFIVE-1-Ni (NbOFFIVE=(NbOF5)2-, 1=pyz, Ni=nickel(II)) like HUMs were synthesized in this study by replaces Nb with V and Ta. Replacing the metal center from Nb to V or Ta showed that the CO2 adsorption isotherm, in particular at low partial pressures, adopted different shapes and gradient. This study shows that the CO2 adsorption properties at low partial pressures on HUMs can be affected by the metal present in the inorganic pillars.
Molecular Descriptor and Criterion for Efficient N-Doping of Organic Semiconductors
Authors: Xu Chunlin , Wang Dong
Published: February 2023

Precursor dopants activated by C-H bond cleavage, especially N-DMBI-H derivates, are the most commonly used n-dopants for organic semiconductors (OSCs), however, their doping mechanism and the structure-activity relationship remain unclear. Here, by rationalizing the thermodynamics and kinetics of the hydrogen atom transfer (HAT) and hydride transfer (HYT) reactions between N-DMBI-H derivates and a variety of OSCs using the density functional theory, we manifest that the HYT via concerted electron and hydrogen atom transfer is the most viable doping mechanism. Furthermore, by correlating important thermodynamic and kinetic parameters of HYT to facile molecular properties, we propose the electron affinity (EA) of OSCs and the ionization energy (IE) of dopant radicals (Ds) as two molecular descriptors of n-doping, and EA(OSC) IE(D) > 1.0 eV as the criterion for high doping efficiency. Finally, new quinoid-structure polymers with EA > 4.0 eV and good backbone planarity are designed as potential n-type OSCs.

Is GPT-3 all you need for low-data discovery in chemistry?
Authors: Jablonka Kevin Maik , Schwaller Philippe , Ortega-Guerrero Andres , Smit Berend
Published: February 2023

Machine learning has revolutionized many fields and has recently found applications in chemistry and materials science. The small datasets commonly found in chemistry lead to various sophisticated machine-learning approaches that incorporate chemical knowledge for each application and therefore require a lot of expertise to develop. Here, we show that large language models that have been trained on vast amounts of text extracted from the internet can easily be adapted to solve various tasks in chemistry and materials science by simply prompting them with chemical questions in natural language. We compared this approach with dedicated machine-learning models for many applications spanning properties of molecules and materials to the yield of chemical reactions. Surprisingly, we find this approach performs comparable to or even outperforms the conventional techniques, particularly in the low data limit. In addition, by simply inverting the questions, we can even perform inverse design successfully. The high performance, especially for small data sets, combined with the ease of use, can have a fundamental impact on how we leverage machine learning in the chemical and material sciences. Next to a literature search, querying a foundational model might become a routine way to bootstrap a project by leveraging the collective knowledge encoded in these foundational models.

Authors: Boswell Benjamin , Mansson Carl , Cabrera Gabrielle , Hansen Calvin , Oliver Allen , Burns Noah
Published: February 2023

Cyclobutadiene is a highly reactive antiaromatic hydrocarbon that has fascinated chemists for over sixty years. However, its preparation and uses in chemical synthesis are sparing, in part due to its lengthy synthesis that generates hazardous byproducts including excess heavy metals. Herein, we report a scalable, metal-free cyclobutadiene reagent, diethyldiazabicyclohexene dicarboxylate, and explore its intermolecular [4+2] cycloadditions with various electron-deficient alkenes. We also demonstrate its utility in a three-step total synthesis of dipiperamide G, and a diverse array of derivatizations including bromocyclobutadiene.

Published: February 2023

A palladium-catalyzed asymmetric three-component synthesis of alpha-arylglycine derivatives starting from glyoxylic acid, sulfonamides and arylboronic acids is reported. This novel, operationally simple method offers access to the alpha-arylglycine scaffold in good yields and enantioselectivities. The utilization of a tailored catalyst system enables the enantioselective synthesis of the desired alpha-arylglycines despite a fast racemic background reaction. The obtained products can be directly employed as building blocks in peptide synthesis.
Acute effects of ankle weight loading on regional activity of rectus femoris muscle and lower-extremity kinematics during walking in older adults
Authors: Narouei Shideh , Akatsu Hiroyasu , Watanabe Kohei
Published: February 2023

Ankle weight loading is a straightforward and easily applicable method to increase the physiological burden during walking in older adults. The current study investigated the acute effects of ankle weight loading on the regional activity of rectus femoris (RF) muscle and lower-extremity joint angles during walking in twenty-nine healthy older adults. Neuromuscular activities of proximal (RFP) and distal (RFD) regions of the RF into averaged rectified values (ARV) and kinematics of left lower extremities were measured during walking with and without ankle weight on a treadmill using surface electromyography (EMG) and motion capture, respectively. Significant differences in normalized ARV between RFP and RFD with ankle weight loading were found in longer periods of the stance phase (30-55 and 5-15%) and swing (70-90 and 95-100%) phases compared to without weight condition (30-40, 50, and 75-85%) (p<.05). The hip flexion angle at (10-25 and 60-90%), knee extension at (5%, 15%, 25-35%, and 100%), and ankle dorsiflexion at (30-55% and 75%) of the gait cycle were increased with ankle weight loading more than without it (p<.05). Ankle weight loading could change the neuromuscular activity pattern of RFP and improve lower-extremity kinematics during walking in older adults.

Published: February 2023

Background: Vaccine hesitancy re-emerged as a critical public health issue during the COVID-19 pandemic. Aims: This study assessed the concerns of recovered COVID-19 patients about vaccination and the predictors of vaccine hesitancy. Methods: This was a cross-sectional study of 319 adult patients who recovered from COVID-19 in Saudi Arabia. It was conducted during 1 May to 1 October 2020 at King Abdulaziz Medical City, Riyadh. Each participant was interviewed 6–12 months post-recovery using the vaccination attitude examination scale. Data were collected on COVID-19 illness severity, sociodemographic characteristics, history of chronic disease, and post-COVID-19 vaccination. Level of vaccination concern was assessed based on the percentage mean score (PMS). Results: Most (85.3%) of the patients who recovered from COVID-19 expressed moderate overall concern (PMS = 68.96%) about vaccination. Concern was highest for mistrust in vaccine benefits (PMS = 90.28%), followed by natural immunity preference (PMS = 81.33%) and worries about the vaccine side-effects (PMS = 60.29%). Concern over commercial profiteering was low (PMS = 43.92%). The overall PMS for concern about vaccination was significantly higher among patients aged 45+ years (t = 3.12, P = 0.002) and among those who had experienced severe COVID-19 illness (t = 1.96, P = 0.05). Conclusion: Overall concern about vaccination was high, and specific concerns were prevalent. Patient education on how the vaccine protects against reinfection should be targeted at COVID-19 patients before being discharged from hospital.
A Study on Design Variables for Increasing the Breaking Strength of Synthetic Fiber Chain
Authors: Kim Kyeongsoo , Kim Seonjin , Cho Hyunwoo , Kim Dokyoun , Kang Yongjun , Kim Taewan
Published: February 2023

In this study, a fiber chain was developed to replace a steel chain using high-modulus polyethylene DM20. The pick count, wrapping count, and inner length were selected as the main design variables of the fiber chain and were analyzed to increase the breaking strength. Orthogonal array experiments were conducted, and the results were analyzed with respect to the breaking strength. The analysis revealed that the pick count and wrapping count had meaningful effects at significance levels within 5%. The main effect analysis revealed that a smaller pick count, larger wrapping count, and longer inner length caused the breaking strength to increase. With the wrapping count fixed at 1, a pick count less than -0.65, and an inner length greater than 0.38, the breaking strength was calculated to be greater than 300 kN. These results are expected be important factors in the derivation of an optimal combination of design variables to attain a fiber chain with a targeted strength.
Artificial Intelligence and Its Ethical Implications for Marketing
Authors: Gonçalves Ana Rita , Pinto Diego Costa , Rita Paulo , Pires Tamara
Published: February 2023

Despite the recent developments in AI, ethical questions arise when consumers contemplate how their data is being treated. This paper develops a conceptual model building on the theory of acceptance, risk, trust, and attitudes towards AI to understand the drivers that lead consumers to accept AI, considering consumers' ethical concerns. The model was empirically tested with 200 consumers of AI marketing services. The findings reveal that perceived risk significantly impacts attitudes toward AI, ethical concerns, and perceived trust and suggest a significant association between perceived risk, ethical concerns, and social norms. This research provides important theoretical and managerial implications for the ethical aspects of AI in marketing by highlighting the ethical and moral questions surrounding AI's acceptance. Doi: 10.28991/ESJ-2023-07-02-01 Full Text: PDF
SPLIT LIGHT: COLORING OF MEDIEVAL DESCRIPTIONS OF PARADISE
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences, Makhov Alexander E.
Published: February 2023

The most important attribute of paradise in most of its medieval descriptions is light, which is usually characterized in superlatives: paradise is filled with such a bright radiance that any differentiation of colors is apparently impossible here. However, some texts suggest a certain, albeit modest, color diversity of paradise: they mention the colors of plants present in paradise, the colors of rivers flowing in it, etc. It seems to us that such a “splitting” of undifferentiated light that dominates paradise space does two functions. First, it symbolically expresses the difference in virtues in terms of their quality and meaning (medieval paradise, like the earthly world, is strictly differentiated, although not in a social but in a moral sense). Differentiation of colors from objects can be transferred to human bodies. Secondly, the coloring of paradise, albeit not rich, corresponds to the multicolor criterion characteristic of medieval artistic thinking: paradise is interpreted as a “decorated” place (in this respect it correlates with “decorated” speech in rhetorical theory), and decoration requires the presence of “colores” (As in rhetoric, embellishment is achieved by using verbal “colores”, i.e. tropes and figures).
THE “OTHER WORLD” IMAGE SPECIFIC IN THE FRENCH CHIVALRIC ROMANCE OF THE 12TH - 13TH CENTURIES
Authors:   Lomonosov Moscow State University, Abramova Marina A.
Published: February 2023

On the material of the novels by Chretien de Troyes (“Cliges”, “Perceval”), the anonymous “Floir and Blanchetflore” and “The Beautiful Stranger” by René de Beaujeu the article examines the basic parameters of marking, the specific features and the semantic load of the otherworldliness in the French chivalric romance at the early stages of its development. The undertaken analysis reveals both mythological and fairy tale markers (crossing the water border, defeating the guard of the reservoir, signs of death, barren land, playing chess) and new ones (imaginary death of the hero or heroine). The article shows how the opposition of two different other worlds in one novel serves to depict the formation and selfidentification of the knight in his two roles – a warrior and a lover, as well as to depict the complex relationship between these roles, the limits of duty and freedom of the hero, the problems of combining courtly love and love sensual, as well as love for and pursuit of wanderings and adventures. It is noted that the portrayal of the other world in the novels is subjected to the author’s creative revision.
MARTIAN THEME IN RUSSIAN MODERN SPIRITUALISM MOVEMENT IN THE LATE 19TH - EARLY 20TH CENTURIES
Authors:   Russian State University for the Humanities, Razdyakonov Vladislav S.
Published: February 2023

The paper investigates spiritualistic perception of Mars by Russian spiritualists in the late nineteenth and early twentieth centuries. It determines historical and cultural specificity of spiritualist attitude to Mars and its Russian background enrooted in the orthodox tradition. The paper overviews popular scientific concepts, which made probable the existence of a highly developed civilization on Mars; it indicates the authoritative spiritual works, which influenced the interest of Russian spiritualists to cosmological problems; it reveals spiritualistic interpretation of spirit messages about the existence of a highly developed civilization on Mars; it considers the cosmological Martian theme in the works of Russian spiritualist I.A. Karyshev. The author argues that the interest in Mars should be explained by the similar nature of epistemological problems encountered by both spiritualists and astronomers. Elusiveness of natural phenomena in positivistic age was the reason that secured Mars a certain place in popular scientific, artistic and spiritualist literature. Аlthough the fideistic view was common among spiritualists, the author claims, that some of them argued for the need to demythologize the spirit messages. I.A. Karyshev’s cosmological system is of interest to the historian of religion as an example of spiritualist construction of Russian planetary utopia and can rightfully take its place in the history of Russian utopian literature.

Published: February 2023

En este trabajo se reporta la composición química y las propiedades ópticas de las partículas finas (PM2.5) y el carbono orgánico soluble en agua (WSOC) de estas partículas. Las muestras se colectaron en un sitio urbano del Área Metropolitana de Monterrey en México durante el invierno 2020 y se caracterizaron mediante espectroscopía infrarroja de transformada de Fourier de reflectancia total atenuada (ATRFTIR), espectroscopia de reflectancia difusa de infrarrojo cercano ultravioleta-visible (UV-Vis-NIR-DRS), espectroscopia de fotoelectrones de rayos X (XPS). La concentración promedio de PM2.5 en San Bernabé sobrepasó el límite de la NOM-025-SSA1-2014, lo cual representa un riesgo potencial a la salud de la población expuesta. Los análisis ATR-FTIR permitieron la identificación de iones inorgánicos (por ejemplo, CO32-, SO42- y NO32-), grupos funcionales orgánicos [por ejemplo, carbonilos (C=O), hidroxilo orgánico (C-OH), ácido carboxílico (COOH)] e hidrocarburos alifáticos aromáticos e insaturados. Los resultados obtenidos por XPS revelaron la presencia de especies químicas orgánicas e inorgánicas en PM2.5. Los espectros de reflectancia difusa proporcionaron las bandas de absorción en la región UV para CaSO4, CaCO3 y aluminosilicatos. Los valores del coeficiente de absorción a 365 nm (Abs365) y del exponente de absorción de Ángstróm (AAE) obtenidos para los extractos acuosos sugieren que muchos de los compuestos orgánicos solubles en agua correspondían a cromóforos de carbono marrón (BrC). Los valores del MAE365 hallados en esta investigación fueron más bajos que los reportados en ciudades altamente contaminadas.
Over The Limit of Authority of The Constitutional Court In Resolving Disputes About The Results of The General Election
Authors: Sodikin Sodikin
Published: February 2023

The limits of authority possessed by the Constitutional Court in deciding disputes regarding the results of general elections as stipulated in Article 24C paragraph (1) of the 1945 Constitution have given a narrow interpretation which is to assess the difference in the figures set by the KPU. The limited authority of the Constitutional Court has caused the decline in the quality of elections. The Constitutional Court does not dare to take on its broader authority even though its position as guardian of the constitution as well as the guardian of democracy. The wider authority of the Constitutional Court needs to be given that every election will always be followed by violations and fraud.

Published: February 2023

The cases of IUU Fishing often occurred in Indonesia. This is due to the lack of supervision by the Indonesian government towards foreign vessels that are still fishing in Indonesian territorial and EEZ.Â  IUU fishing caused huge losses to the country. One of the perpetrators of this illegal act was the Thai Silver Sea 2 ship. The ship entered Indonesian territorial waters precisely in Sabang waters, by flying the Indonesian flag to trick the Indonesian government patrolling around Sabang waters. However, gradually the Indonesian government became aware of the existence of foreign vessels which had been suspected by Indonesia for a long time because it often turned off VMS so that its existence could not be detected by the Indonesian government. This study will examine more deeply related to whether the action conducted by Silver Sea 2 Vessels violate Indonesian regulation and UNCLOS 1982? And is the legal enforcement of Illegal Unreported and Unregulated Fishing taken by Indonesian government compatible with UNCLOS 1982?. This research is a normative legal research with a statute approach, and a conceptual approach. Legal material collection techniques are carried out by examining the relevant literature, analyzing various legal references relevant to the problem related to the study to be analyzed further qualitatively and descriptively. The results showed that the actions of SS2 ships violated Indonesian legislation and UNCLOS 1982 and were appropriate when this case was handled by the Sabang district court.

Authors: Mulhimmah Baiq Ratna , Olagunju Ridwan
Published: February 2023

Copyright Protection of Indonesian Indigenous Peoples in the form of Traditional Knowledge (TK) &Traditional Cultural Expression (TCE) currently does not meet the sense of justice. The state is obliged to provide comprehensive protections capable of guarding the rights of Indigenous peoples under an adequate legal umbrella. Because the existence of Indigenous peoples, along with copyrights in the form of TK & TCE is part of the wealth and identity of the nation, this research focuses on how the view of Islamic law (Legal Opinion of Indonesian Ulama Council No.1 of 2003 concerning Copyright and Legal Opinion Of Indonesian Ulama Council No.1 of 2005 concerning Intelectual Property Right) with the maqasid al Shariâ€™ah approach in protecting the rights of indigenous peoples. Islamic law is one of the secondary legal materials in determining state law and is expected to strengthen in providing solutions to this problem. The research method is normative with a concept and case approach to conclude that Islamic law (legal Opinion Of Indonesian Ulama Council) with the Maqasid al Shariâ€™ah approach in protecting Traditional Knowledge (TK) &Traditional Cultural Expression (TCE) is a must. This is based on an obligation order covering several matters, including; the protection of life and hifzul nafsi/hifzul â€˜irdhi, protection of reason (hifzul aqli), and protection of property (hifzul maal).

The establishment of a Local-Owned Enterprises (BUMD) operating in the banking sector has a strategic role for the people and the Government of Batu City in order to improve the economic status, public service, and competitiveness in the financial sector, and is an attempt to increase the regionally generated revenue as mandated by Law Number 23 of 2014 and Government Regulation Number 54 Year 2017. However, with the regulatory space and authority it has so far, Batu City Government has not established the BUMD as intended. Moreover, this paper will explain sociological aspect and the choice for politic of law for the Batu City Government in the framework of BUMD establishment in banking sector. Based on these circumstances, this paper uses a normative juridical research method to see regional community needs for banking financial institution owned by the Batu City Government. Based on the provisions of the legislation, the Batu City Government in preparing the process of establishing a BUMD begins with the formation of a BUMD formation team consisting of elements of the relevant Regional Apparatus, and prepare a research of regional needs and the feasibility of business fields in the banking sector to ensure the next step is to prepare and compile Regional Regulations governing the establishment of BUMD and ratification of legal entities by a notary through the Legal Entity Administration System of the Ministry of Law and Human Rights. According to theory and authoritative regulations, the formation of BUMD may be carried out in the form of a Legal Entity for a Regional Corporation, while the banking enterprise activities may be in the form of Peopleâ€™s Credit Banks (BPR) or Sharia Peopleâ€™s Financing Banks (BPRS).

Published: February 2023

Pola pertanian yang dilakukan oleh masyarakat Indonesia berfariasi, sebagian besar menggunakan lahan tetap dan ada juga yang menggunakan konsep lahan berpindah. Tidak jarang kearifan lokal masyarakat dalam pengelolaan lahan pertanian adalah dengan cara membakar, hal ini untuk meminimalisir penggunaan pestisida terhadap kesuburan tanah. Penelitian ini bertujuan untuk mengetahui hak masyarakat dalam pengelolaan lahan pertanian dan akibat hukum pengelolaan lahan yang berdampak pada lingkungan. Penelitian ini menggunakan metode normative-sosiologis, menganalisis produk hukum yang berlaku seperti (UU Pertanian, UU Lingkungan dan KUHP) kemudian disinkronkan dengan beberapa putusan pengadilan sehingga menghasilkan deskripsi. Hasil penelitian memperlihatkan bahwa UU memberikan ruang kepada masyarakat sesuai kearifan lokal untuk membuka dan mengelola lahan pertanian dengan cara membakar, tetapi UU tersebut membatasi luasan lahan yang diperbolehkan untuk dibakar yakni maksimal 2 (dua) hektar per kepala keluarga. Beberapa kasus pembakaran lahan diputus oleh pengadilan bersalah dikarenakan api meluas hingga melebihi batas maksimal, beberapa mengenai lahan pertanian dan membahayakan lahan orang lain.Â

Published: February 2023

The existence of illegal fintech is still a public concern due to the inadequate regulation tools that are able to regulate and take firm action against the existence of illegal fintech. The difficulty faced by regulators in taking action against illegal fintech is because it is difficult to be tracked and illegal entities that have been blocked can easily recreate new illegal fintech entities. This study was conducted by using normative legal research, which was reviewing material law that contains normative legal rules. As the result, there are conclusion namely, first Illegal fintech P2PL actors try to trick the public by resembling the companyâ€™s platform name and/or logo, name, and identity color from legal fintech P2PL that has been registered/licensed at the OJK and SWIâ€™s efforts to take action against these fintech P2PL companies are by blocking sites, conducting joint inspections of business activities which assumed as illegal investments, ordering illegal fintech P2PL companies to stop business activities, and improving coordination in handling cases with related agencies. OJK through SWI seeks to stop the chain of Illegal fintech P2PL by routinely coordinating with the Minister of Communication and Information to block illegal services

Hak pendidikan telah diatur dalam Undang-Undang Dasar 1945 dan Undang-Undang Nomor 20 Tahun 2003 Tentang Sistem Pendidikan Nasional, Peraturan Pemerintah No. 47 Tahun 2008 Tentang Wajib Belajar. Kabupaten Lingga merupakan salah satu daerah di Provinsi Kepulauan Riau yang masih banyak dikelilingi oleh masyarakat suku laut. Pulau Kelumu adalah salah satu pulau yang berada di Kabupaten Lingga yang masih dihuni oleh masyarakat suku laut. Masyarakat suku laut adalah masyarakat asli di Kabupaten Lingga. Tujuan dalam penelitian ini adalah menganalisis pemenuhan hak pendidikan untuk anak suku laut di Pulau Kelumu Kabupaten Lingga. Metode penelitian yang digunakan dalam penelitian ini adalah yuridis empiris dan menggunakan Teori Efektivitas Hukum Oleh Soerjono Soekanto. Hasil penelitian ini menunjukan bahwa pemenuhan hak pendidikan bagi anak suku laut di Pulau Kelumu Kabupaten Lingga masih belum efektif jika diukur dengan Teori Efektivitas hukum tersebut, karena kurangnya faktor sarana prasarana yaitu ketersediaan sekolah yang terbatas, masyarakat, dan budaya yang melakukan perkawinan anak hingga menjadikan anak tersebut putus sekolah. Oleh sebab itu, rekomendasinya adalah menciptakan lapangan pekerjaan bagi masyarakat suku laut, membangun sekolah pada tingkat SMP dan SMA yang berlokasi di wilayah Pulau Kelumu.

Authors: Isnaeni Atin Meriatin
Published: February 2023

Penelitian ini dimaksudkan untuk menjawab dua isu hukum utama yaitu : (1). Pihak manakah yang berkewajiban melakukan pembayaran premi asuransi bankerâ€ s clause dalam perjanjian kredit?Â Â  Â (2). Bagaimankah tanggungjawab bank terhadap kelalaiannya untuk menyampaikan tanggal jatuh tempo pembayaran asuransi bankerâ€™s calause dalam perjanjian kredit? Â Penelitian ini merupakan penelitian hukum normative dengan metode pendekatan: Pendekatan perundang-undangan (statute approach), Pendekatan konseptual (conceptual approach) dan Pendekatan Kasus (Case Approach).Â  Hasil penelitian menunjukan 1). Bahwa meskipun pencantuman bankerâ€™s clause ditujukan untuk kepentingan pihak Bank, namun kewajiban untuk membayar premi asuransinya merupakan kewajiban pihak debitur pemilik obyek jaminan. 2). Bahwa kelalaian bank dalam menyampaikan tanggal jatuh tempo pembayaran asuransi bankerâ€™s clause kepada debitur yang mengakibatkan tidak dapat diclaimnya asuransi obyek jaminan kredit maka debitur dapat menggugat pihak bank atas dasar telah melakukan perbuatan melanggar hukum (onrechtmatigedaad).

Fitoplankton adalah salah satu mikroorganisme autotrof yang perperan penting dalam mengubah bahan anorganik menjadi bahan organik yang hidup melayang di permukaan perairan. Penelitian ini bertujuan untuk mengetahui kelimpahan, keanekaragaman, keseragaman, dan dominansi fitoplankton di Perairan Desa Baruta Analalaki, Kecamatan Sangia Wambulu Kabupaten Buton Tengah. Penelitian dilaksanakan mulai bulan Oktober sampai dengan November 2022. Alat yang digunakan yaitu Seichidisk, Termometer, Refraktometer, dan Planktonnet. Bahan yang digunakan dalam penelitian adalah sampel air yang diambil dari lokasi dan sudah ditentukan pada saat pagi, siang, dan sore hari. Metode yang digunakan dalam penelitian ini adalah metode purposive random sampling, yaitu Metode yang digunakan untuk memudahkan peneliti dalam menentukan lokasi sampling sesuai dengan kriteria yang diinginkan oleh peneliti (Hadi, 2004). Hasil penelitian Menunjukkan bahwa ditemukan tiga kelas fitoplankton yaitu dari kelas Bacillariophyceae, Chlorophyceae, dan Dinophyceae. Dari ketiga kelas tersebut yang paling banyak ditemukan dari kelas Bacillariophyceae. Tingkat kelimpahan fitoplankton tergolong cukup subur yakni terjadi pada siang hari pada jam 12.00-14.00 ditemukan 968-1120 jenis, sedangkan pada pagi dan sore hari justru kelimpahan fitoplankton tergolong sedang. Indeks keanekaragaman rata-rata masuk kategori sedang, namun pada jam 14.00 ditemukan indeks keanekaragaman tinggi yaitu 3,05. Selanjutnya indeks keseragaman menunjukkan kategori rendah. Hal ini disebabkan karena adanya persaingan ruang dan makanan antar jenis fitoplankton. Dominansi pun tergolong rendah artinya tidak ada spesies yang mendominasi. Uji korelasi Pearson antara kelimpahan fitoplankton dan parameter kualitas air memiliki kaitan yang sangat kuat dengan nilai r = 0,715 (kecerahan), dan r = 0,526 (suhu). Analisis regresi memiliki persamaan Y = 1761+183X1+126X2. Hasil tersebut menunjukkan koefisien perbandingan kecerahan dan suhu bernilai positif yang artinya jika terjadi peningkatan sebesar 1 cm maka tingkat kelimpahan fitoplankton akan naik sebesar 183 atau 126 dengan asumsi parameter lainnya konstan. Berdasarkan hasil tersebut, nilai kecerahan dan suhu yang tinggi menunjukkan kelimpahan fitoplankton juga tinggi di Perairan Desa Baruta Analalaki.

Di Jawa Barat persentase penduduk semakin meningkat setiap tahunnya. Berdasarkan data BPS 2020, diprediksi pada tahun 2025 penduduk perkotaan akan mencapai 83,1%, tahun 2030 mencapai 86,6% dan pada tahun 2035 persentase penduduk perkotaan di Jawa Barat mencapai 89,3%. Dengan pesatnya pertumbuhan penduduk perkotaan, maka pemenuhan kebutuhan perumahan mengalami peningkatan. Didalam pemenuhan pembangunan perumahan berkaitan erat dengan pertimbangan akses terhadap fasilitas. Akan tetapi disisi lain pembangunan perumahan baru yang ada, tidak selalu di imbangi dengan adanya penyediaan infrastruktur PSU yang sesuai dan hal tersebut dapat dijumpai pada perumahan pola cluster < 10.000. Salah satu kawasan yang banyak terdapat sebaran perumahan pola cluster < 10.000 yakni Kecamatan Katapang di Kabupaten Bandung. Didalam studi dilakukan untuk melihat keterpaduan PSU di sekitar kawasan perumahan pola cluster. Pendekatan yang dilakukan yaitu campuran, agar memberi pemahaman dan hasil akhir yang lebih baik dalam mengetahui implikasi pengembangan perumahan pola cluster terhadap keterpaduan prasarana, sarana dan utilitas umum. Analisis yang digunakan yaitu Analisis Perkiraan Kebutuhan Pengembangan Sarana Fasilitas, Cakupan Pelayanan Fasilitas, Customer Satisfaction Index (CSI), Deskriptif Evaluatif dan Triangulasi. Dari hasil Analisa didapatkan bahwa terdapat beberapa kebutuhan penambahan PSU di beberapa perumahan pola cluster, serta kurang terpadunya PSU wilayah yang ada karena berada di luar kriteria cakupan pelayanan yang ditetapkan oleh SNI 03-1733-2004.

Mathematics teachers’ awareness of effective teaching practices: A comparative study
Authors: Mohamed Rasha H. , Khalil Ibrahim A. , Awaji Bakri M.
Published: February 2023

This study aimed to explore mathematics teachers’ awareness of effective teaching practices issued by the United States National Council of Teachers of Mathematics (NCTM, 2014a) in the Kingdom of Saudi Arabia and the Arab Republic of Egypt and to compare the results using the comparative descriptive method. The Saudi sample comprised 651 teachers, and the Egyptian sample included 620 teachers. Data were collected through an awareness scale of eight dimensions of effective teaching practices. The study found that mathematics teachers in the Kingdom of Saudi Arabia and the Arab Republic of Egypt had high awareness of effective teaching practices. In addition, no differences were found in Saudi teachers’ awareness of potentially differentiating variables. However, there were differences attributable to the gender variable in favor of the female group. For Egyptian teachers, the results showed no statistically significant differences in awareness levels concerning gender and school stage. However, those with higher qualifications (master’s and doctoral degrees) showed significantly higher awareness than those with an average teaching experience of five-nine years. We identified areas to support high-quality mathematics teaching and learning for future professional development by highlighting and examining mathematics teachers’ awareness of effective practices. These findings have important implications for mathematics instruction specialists, coaches, and stakeholders in both countries.
Mitos clásicos en el viaje cognoscitivo de Amor sin fin de Claribel Alegrí­a
Authors: Fernández Zambudio Josefa
Published: February 2023

En este artículo, analizamos los mitos grecolatinos en el poemario Amor sin fin de Claribel Alegría (2016), que plantea este viaje cognoscitivo como una introspección en la que se vislumbra la muerte, pero aún no es posible la ansiada reunión con el marido ya fallecido. Este trabajo llena un vacío entre los estudios acerca de Claribel Alegría, que han tratado poco frecuentemente su último poemario y que han proporcionado datos respecto de su uso de la mitología clásica sin relacionarlo con los temas esenciales de su poética: el amor, la muerte y la metaliteratura. Por ello, pondremos en relación los versos que concluyen la obra de la autora con el resto de sus poemarios, a través del análisis de los textos donde aparecen personajes relacionados con los temas principales del poemario y la identificación con diversas máscaras míticas. El resultado es un diálogo con la tradición literaria y la propia obra a través de los mitos que definen el espacio en el que se sitúa el yo poético, el umbral, la suspensión entre la vida y la muerte, donde se permite el conocimiento. En las conclusiones, la mitología clásica se descubre como clave esencial para la lectura del poemario, permitiendo profundizar en su forma y contenido, y descubrir la conexión con la poética y la escritura de Alegría.
