Glucocorticoid Discontinuation in Patients With Systemic Lupus Erythematosus With Prior Severe Organ Involvement: a Single-center Retrospective Analysis
Authors: Okada Masato , Fukui Sho , Ikeda Yukihiko , Suda Masei , Tamaki Hiromichi , Nakai Takehiro
Published: September 2021

Background:Long-term glucocorticoid use in systemic lupus erythematosus (SLE) may have significant side effects; however, glucocorticoid discontinuation is occasionally associated with disease flare-ups. Therefore, we evaluated the risk factors for disease flares and the flare rate upon glucocorticoid tapering in patients with prior severe organ involvement.Methods:Patients with SLE with glucocorticoid tapering at our institution were retrospectively analyzed. We divided the patients according to the presence of prior severe organ involvement and compared flare rates and time to first flare after glucocorticoid discontinuation. Furthermore, we determined risk and protective factors for flares after glucocorticoid discontinuation.Results:A total of 309 patients with SLE were screened; 298 had prednisolone tapered to less than 7.5 mg/day and 75 had glucocorticoid discontinuation. Overall, 73 patients met the inclusion criteria; 49 were classified as SLE with prior severe organ involvement. No statistical differences were noted in the 52-week flare rate and time to first flare after glucocorticoid discontinuation between patients with and without prior severe organ involvement (52-week flare rate: 16.7% vs. 18.2%, p = 1.0; time to first flare: 322 [280, 1169] vs. 385 [304, 2345] days, p = 0.33). Hypocomplementemia, elevated anti-dsDNA antibody titers of more than twice the upper limit of the laboratory reference range, and positive anti-Smith/anti-ribonucleoprotein antibody were negatively associated with flare-free remission.Conclusion:Glucocorticoid discontinuation can often be achieved in patients with SLE without increasing flare risk in most patients with prior severe organ involvement, especially when the disease is clinically and serologically stable.
Spatial Phase Synchronisation of Pistachio Alternate Bearing
Authors: Sakai Kenshi , Brown Patrick , Rosenstock Todd , Upadhyaya Shrinivasa , Hastings Alan
Published: September 2021

Nonlinear physics and agroecosystems can be of great relevance in the synchronisations of chaotic oscillators. The endogenous dynamics of the seed production of perennial plant species which include alternate bearing and masting, portray typical synchronisation patterns in nature and can be modelled using a tent map known as a resource budget model (RBM). This study investigates the collective rhythm in 9,562 pistachio trees caused by their endogenous network dynamics and exogenous forces (common noise). Common noise and a local coupling of RBMs are the two primary factors emerging from the bearing phase synchronisation in this orchard. The in-phase/out-of-phase analysis technique quantifying the strength of the phase synchronisation in trees (population /individual) allows us to study the observed spatial synchrony in detail. We demonstrate how three essential factors, i.e. (a) common noise, (b) local direct coupling, and (c) the gradient of the cropping coefficient, explain the spatial synchrony of the orchard. Here, we also show that the methodology employing nonlinear physics to study agroecological systems can be useful for resolving practical problems in agriculture including yield variability and spatial synchrony which often compromise efficient resource management.
Using CFD To Assess The Impact of Helical Baffle On The First- Law And Second-Law Performance of Water-CuO Nanofluid Inside A Hairpin Heat Exchanger
Authors: Shahsavar Amin , Toghraie Davood , Barnoon Pouya
Published: September 2021

This study is devoted to the numerical assessment of the influence of helical baffle on the hydrothermal aspects and irreversibility behavior of the turbulent forced convection flow of water-CuO nanofluid (NF) inside a hairpin heat exchanger. The variations of the first-law and second-law performance metrics are investigated in terms of Reynolds number (Re), volume concentration of NF (φ) and baffle pitch (B). The results showed that the NF Nusselt number grows the rise of both the Re and φ whereas it declines by boosting with the rise of baffle pitch. In addition, the outcomes depicted that the rise of both the T and φ results in the rise of pressure drop, while it declines with the increase of baffle pitch. Moreover, it was found that the best first-law performance of the NF belongs to the case B=33.3 mm, φ=2% and Renf=10000. Furthermore, it was shown that irreversibilities due to fluid friction and heat transfer augment with the rise of Re while the rise of baffle pitch results in the decrease of frictional irreversibilities. Finally, the outcomes revealed that with the rise of baffle pitch, the heat transfer irreversibilities first intensifies and then diminishes.
Examining Stakeholder’s Views On Refugee Healthcare Needs, Current Barriers in Accessing Healthcare Services and Future Healthcare Direction in New Zealand: A Qualitative Phenomenological Approach
Authors: Sherif Bafreen , Awaisu Ahmed , Kheir Nadir
Published: September 2021

Background

The annual New Zealand refugee quota was increased to 1500 places from 2020 onwards as a response to the global refugee crisis. The specific healthcare needs of refugees are not clearly understood globally and communication between healthcare providers and refugees remains poor.
Methods

A phenomenological qualitative methodology was employed to conduct semi-structured interviews among purposively selected stakeholders who work in refugee organisations and relevant bodies in New Zealand.
Results

The participants indicated the need for a national framework of inclusion, mandating cultural competency training for frontline healthcare and non-healthcare personnel, creation of a national interpretation phone line, and establishing health navigators. Barriers to accessing health services identified included some social determinants of health such as housing and community environment; health-seeking behaviour and health literacy; and social support networks. Future healthcare delivery should focus on capacity building of existing services, including co-design processes, increased funding for refugee-specific health services, and whole government approach.
Conclusion

Policymakers and refugee organisations and their frontline personnel should seek to address the deficiencies identified in order to provide equitable, timely and cost-effective healthcare services for refugees in New Zealand.
A revised analysis of ferrihydrite at liquid helium temperature using Mössbauer spectroscopy
Authors: Byrne James M. , Kappler Andreas
Published: September 2021

Short-range-ordered Fe(III) minerals such as ferrihydrite (Fh) are ubiquitous in the environment, are key players in biogeochemical cycling, and sorb trace elements and nutrients. As such, it is important to be able to identify the presence of such minerals in natural samples. Fh is commonly observed to be X-ray amorphous and cannot be easily analyzed using X-ray diffraction, meaning that spectroscopic methods such as X-ray absorption or 57Fe Mössbauer spectroscopy (MBS) are necessary for accurate identification and quantification. Despite decades of research into Fh using MBS, there is a discrepancy in the literature about the exact parameters applicable to the mineral when measured at liquid helium temperature. Fh is frequently fitted with either one, two, or three hyperfine sextets with little interpretation applied to the meaning of each, which is problematic as a one sextet model does not account for the asymmetric lineshape frequently observed for Fh. Here, we address inconsistencies in the fitting of Fh and provide a more standardized approach to its identification by MBS. We present a systematic comparison of different fitting methods, notably based on Lorentzian and Voigt functions. We suggest that the most suitable approach to fitting pure Fh at liquid helium temperature is with two sextets (A and B) fitted using an extended Voigt-based function with the ability to apply probability distributions to each hyperfine parameter. 2-line Fh: A (δ = 0.49 mm/s; ε = 0.00 mm/s; Bhf = 50.1 T) and B (δ = 0.42 mm/s; ε = –0.01 mm/s; Bhf = 46.8 T) 6-line Fh: A (δ = 0.50 mm/s; ε = –0.03 mm/s; Bhf = 50.2 T) and B (δ = 0.40 mm/s; ε = –0.05 mm/s; Bhf = 47.1 T). We interpret the two sextets to be due to either differences in the coordination environment of iron, i.e., in tetrahedral or octahedral sites, the presence of a disordered surface phase, or a combination of both. We hope that provoking a discussion on the use of MBS for Fh will help develop a greater understanding of this mineral, and other short-range ordered iron minerals, which are so important in environmental processes.
3d large $N$ vector models at the boundary
Authors: Di Pietro Lorenzo , Lauria Edoardo , Niro Pierluigi
Published: September 2021

We consider a 4d scalar field coupled to large NN free or critical O(N)O(N) vector models, either bosonic or fermionic, on a 3d boundary. We compute the \betaβ function of the classically marginal bulk/boundary interaction at the first non-trivial order in the large NN expansion and exactly in the coupling. Starting with the free (critical) vector model at weak coupling, we find a fixed point at infinite coupling in which the boundary theory is the critical (free) vector model and the bulk decouples. We show that a strong/weak duality relates one description of the renormalization group flow to another one in which the free and the critical vector models are exchanged. We then consider the theory with an additional Maxwell field in the bulk, which also gives decoupling limits with gauged vector models on the boundary.
Do Chinese-focused U.S. listed SPACs perform better than others do?
Authors: Gigante Gimede , Maria Guidotti Giovanni
Published: September 2021

The extraordinary growth of China from the early 2000s until now made it one of the biggest economies in the world. Over the years, more and more Chinese companies merged with the U.S. listed special purpose acquisition companies (“SPACs”) to become public and attract foreign capital. This paper examines the differences between this specific subsample of SPACs focused on completing a merger with a business located in China among those listed on the U.S. Stock Exchanges and the other U.S. listed SPACs. The intent is to verify whether the sample differs from the rest of the market in their main characteristics, have better, equal, or worse prospects of completing a merger, and offer better, equal, or worse returns to investors. 329 SPACs were identified, of which 41 targeting Chinese businesses. Logistic regression is performed to understand whether the China market focus influences the chances of consuming a business combination. Moreover, two different models (event study approach and buy-and-hold approach) are implemented to assess the share performances of the two subsamples. The conclusions that stem from the obtained results are that China-focused SPACs differ consistently from the rest of the market in certain features but need similar time to identify a target and close the deal. Focusing on China seems to be beneficial for the SPAC’s prospects of closing a deal, being statistically significant at a 10% level. Last, a portfolio composed of the sample SPACs’ shares overperforms the non-China one in both the short and long terms.
Acknowledgment The authors would like to thank their brilliant student, Mr. Daniele Notarnicola, for the precious support given during the review of the paper.
KÜLTÜRE ÖZGÜ ÇOCUK OYUNLARININ İNCELENMESİ ÖRNEKLERİYLE LAZ KÜLTÜRÜ: RİZE ARDEŞEN ÖRNEĞİ
Authors: TANJU ASLIŞEN Ebru Hasibe
Published: September 2021

Kültür, kuşaktan kuşağa aktarılarak yaşatılmakta, kültürel kodlar aracılığıyla nesilden nesile iletilmekte ve bu kodlar arasında çocuk oyunları da önemli bir yer tutmaktadır. Oyunlarında, içinde yaşadıkları toplumun sosyal-kültürel unsurlarını yansıtan çocuklar, bu sayede hem sosyal ilişkilerinin kuvvetlenmesine hem de kültürel sürekliliğin devamına katkıda bulunurlar. Ancak yaşam koşullarının hızla değiştiği günümüzde, yaşanılan şartlara bağlı olarak geleneksel kültürler gibi bu kültürlere özgü oyunlar da yavaş yavaş unutulmaya başlamış, yerlerini bilgisayara ve internete bağlı oyunlara bırakmıştır. Bu durum Laz kültüründe de benzerlik göstermektedir. Horonları, tulumları, fıkraları aklımıza ilk gelen kültürel motifleri olsa da oynanış biçimleriyle, kullanılan malzemeleriyle, sosyal katılımın çeşitliliğiyle, dilsel farklılıklarıyla Laz kültürüne özgü dikkat çeken çocuk oyunları da bulunmaktadır. Konuyla ilgili yazılı kaynakların azlığı da dikkate alınarak planlanan bu çalışmada amaç, etnik kimliğe odaklanmadan Lazlar arasında farklı oynanış şekillerini barındıran oyunlar ile sadece Laz kültürüne özgü çocuk oyunlarından birkaçının içeriklerini, oynanış şekillerini, oyunlarda kullanılan oyuncakları/araç-gereçleri örneklerle detaylandırmaktır. Bu amaçla çalışmada nitel veri toplama yöntemlerinden görüşme tekniği kullanılmış ve sohbet tarzı görüşme yaklaşımıyla kültüre özgü örnek çocuk oyunlarına ulaşılmıştır. Gönüllü beş katılımcı ile gerçekleştirilen görüşmeler esnasında ses kayıtları alınmış ve elde edilen bilgiler daha sonra yazılı metin haline getirilmiştir.

Published: September 2021

Introduction: Library collection development is a routine activity and must be carried out by all libraries. Even though it has become a routine activity, it is not uncommon for this activity to become difficult to do, as was the case with the Muhammadiyah University of Ponorogo Library which experienced difficulties in developing the Reyog Corner collection, a corner or reading corner containing various collections containing about Reyog and Ponorogo Regency. This study aims to determine the strategy carried out by the Muhammadiyah University of Ponorogo Library in developing a collection for that corner. Methodology: This study uses a qualitative method with a descriptive approach in conducting research. Results and Discussion: Based on data analysis and studies conducted, the authors found the results if the obstacles faced in developing collections for Reyog Corner were the lack of library materials containing the study/theme. However, various efforts were made to develop Reyog Corner, including establishing contacts with local governments, direct searches for authors, and independent searches based on subjects through various online shops. Conclusion: The results of this study are expected to be a reference for readers in developing collections in workplace libraries and private libraries, especially collections that have a certain uniqueness.

Computational Analysis Illustrates the Mechanism of Qingfei Paidu Decoction in Blocking the Transition of COVID-19 Patients from Mild to Severe Stage
Authors: Chen Wei , Li Xianhai , Xiang Liu , Lin Yue , Tang Qiang , Meng Fanbo
Published: September 2021

Background:

The epidemic of SARS-CoV-2 has made COVID-19 a serious threat to human health around the world. The severe infections of SARS-CoV-2 are usually accompanied by higher mortality. Although the Qingfei Paidu Decoction (QFPDD) has been proved to be effective in blocking the transition of COVID-19 patients from mild to severe stage, its mechanism remains unclear.

Objective:

This study aims to explore the mechanism of QFPDD in blocking the transition of COVID- 19 patients from mild to severe stage.

Materials and Methods:

In the process of screening active ingredients, oral bioavailability (OB) and drug likeness (DL) are key indicators, which can help to screen out pivotal compounds. Therefore, with the criteria of OB≥30% and DL≥0.18, we searched active ingredients of QFPDD in the Traditional Chinese Medicine Systems Pharmacology (TCMSP, https://tcmspw.com/) by using its 21 herbs as keywords.

Results:

We filtered out 6 pivotal ingredients from QFPDD by using the bioinformatics method, namely quercetin, luteolin, berberine, hederagenin, shionone and kaempferol, which can inhibit the highly expressed genes (i.e. CXCR4, ICAM1, CXCL8, CXCL10, IL6, IL2, CCL2, IL1B, IL4, IFNG) in severe COVID-19 patients. By performing KEGG enrichment analysis, we found seven pathways, namely TNF signaling pathway, IL-17 signaling pathway, Toll-like receptor signaling pathway, NFkappa B signaling pathway, HIF-1 signaling pathway, JAK-STAT signaling pathway, and Th17 cell differentiation, by which QFPDD could block the transition of COVID-19 patients from mild to severe stage.

Conclusion:

QFPDD can prevent the deterioration of COVID-19 in the following mechanisms, i.e. inhibiting SARS-CoV-2 invasion and replication, anti-inflammatory and immune regulation, and repairing body damage. These results will be helpful for the prevention and treatment of COVID-19.
‘Mattering’ Women’s Lives on Screen: An Introduction
Authors: Theuer Eugenie
Published: September 2021

The aim of this introduction is to provide a context for the articles that follow in this cluster on Women’s Lives on Screen. Starting with some reflections on how biopics can matter to audiences, I propose the use of ‘mattering’ as a concept for the study of women’s biopics which helps consider their objectification of women as biographical ‘material’ on screen in tandem with their emancipatory refiguring of women as biographical subjects that are made to matter. The introduction also offers a brief overview of biopic studies as they relate to the subject of women’s lives on screen. It ends by sketching the breadth of topics covered in this cluster with a summary of the eleven articles.
‘Full cause of weeping’: Affective Failure in The Queen (2006) and The Crown (2019)
Authors: Layne Bethany
Published: September 2021

This article reads The Crown, Series Three, Episode Three, ‘Aberfan’, as an adaptation of The Queen, both of which were written by Peter Morgan. Each focuses on a crisis in public relations emerging from Elizabeth II’s delayed reaction to a tragedy: the mining disaster in The Crown and the death of Princess Diana in The Queen. Both are double portraits, in which the monarch’s affective failure is contrasted with the more humane response of the prime minister, Harold Wilson and Tony Blair respectively. And both texts explore the tension between private grief and public performance. By reading these texts in dialogue, their relevance to their contemporary contexts is magnified. The Queen uses Elizabeth II’s nadir in public relations to comment on Blair’s fall from grace as a result of the Iraq War, while ‘Aberfan’, by emphasising the avoidable nature of the disaster, comments on the Grenfell Tower fire of 2017. While neither text shrinks from criticising the monarch for her breakdown in empathy, the resonances between Aberfan and Grenfell allow the Queen’s immediate and humane response in 2017 to redeem her delayed reactions in the past. This demonstrates the capacity of fictional texts to intervene in the popular perception of their subjects.
What’s Whitney Got to Do with It: Black Female Triumph and Tragedy in the 2015 Lifetime Biopic Whitney
Authors: Kooijman Jaap
Published: September 2021

In 2015, the cable television network Lifetime broadcast the biopic Whitney, depicting the troubled life of the late superstar singer Whitney Houston. Whitney is the first film by director Angela Bassett, who, as actress, famously portraited Tina Turner in the biopic What’s Love Got to Do with It (Brian Gibson, 1993). In this article, I will first position Whitney within a larger tradition of the Hollywood biopic by making a comparison to earlier important biopics about black female entertainers, namely Lady Sings the Blues (Sidney J. Furie, 1972), starring Diana Ross as Billie Holiday, and What’s Love Got to Do with It. Second, I will discuss how the narratives of these three biopics tend to reduce their female subjects to victims, emphasizing the tragedy in their personal lives, while assigning much more agency to the male partners of these black female entertainers. Third and finally, I will analyze the final scenes of these three biopics in detail, as each presents a grand finale musical performance that seems to resolve the contradictions of the triumph and tragedy in their subject’s lives, yet in significantly different ways.
‘The Great Scene That Never Happened’ – A Screenwriter’s Techniques of Blending Fact and Fiction in Creating a Compelling Character Arc in Biopics
Authors: Hinterkörner Maria
Published: September 2021

The biopic as a genre treads a thin line between fact and fiction. Using the theory and methods of visual storytelling and screenwriting, I will lay open the thought process and the tools of the craft that are employed to create a character arc using historical facts and figures for a movie that will resonate with a modern audience. I will also show how I tried to incorporate the producers’ expectations regarding the subject matter. I illustrate my process and techniques using my most recent screenplay Ushba, which narrates the unsuccessful climb of the eponymous Georgian mountain by a group of Austrian mountaineers, among them a young woman called Cenzi von Ficker.
Anne Smith, Ina Lohr (1903-1983). Transcending the Boundaries of Early Music
Authors: Fischer Christine
Published: September 2021

This is a book that had to be written. And that is meant in a thoroughly positive way. Ina Lohr, ‘Paul Sacher's assistant’, is a well-known figure in insider circles, who contributed immensely to the creation of the Schola Cantorum Basiliensis, one of the most important international teaching institutions for Early Music and historically informed performance practice. Lohr made a significant contribution to the emergence of the Basel Chamber Orchestra, which made a name for itself not only in Early Music but also, through regular commissions from the Sacher-family, in the field of New Music as yet another unique Basel contribution to the international music life. However, the exact nature of the contributions of Lohr is not entirely clear even to locals and insiders who did have the privilege of meeting her themselves. Especially, her own compositional activity has so far been carefully left out of the prevailing ‘image’ of the conservatively dressed and coiffed Lohr who taught ‘house music courses’ (the name of teacher training at the time).
Diversity and Seasonal Variations of Zooplankton in Kampli Water Tanks in and Around Hosapete City, Karnataka (India)

Published: September 2021

Abstract: This study focuses on assessment of zooplankton with special reference to seasonal variation and selected physicchemical variables of Kampli water tanks in Hosapete city, Karnataka state. A large quantity of manmade activities near the water tank. During the study period, 48 species of zooplankton - 14 species of Rotifera, 12 species of Cladocera, 6 species of Ostracoda and 4 species of Copepoda were observed. Among zooplankton, Rotifera was (645 no./Org) noticed as the dominant group in the entire the study period and the maximum count was identified in the summer period while less numbers were noticed during winter season. Zooplankton community is also significantly correlated with some physico-chemical variables. The analytical results during the study period indicate that the scattering and density of zooplankton species were encouraged by prevailing physical and chemical features of the aquatic ecological condition. Keywords: Kampli, water tank, zooplankton, diversity, seasonal and domestic activity.
Analysis and Geotechnical Design of Hybrid Foundation for Tall Wind Turbine
Authors: Birhare Shruti
Published: September 2021

Abstract: The significance of wind turbines in meeting the expanding energy demand is critical. Taller towers should be employed to boost the power producing capability. The foundation must be efficient in order to securely carry the heavier loads of taller towers. When sustaining loads from superstructure are considered then bearing capacity of raft is taken into account for pile raft foundation. Piles help to strengthen the raft's bearing capacity while also regulating settlement in this arrangement, particularly differential settlement. A hybrid foundation, i.e. a pile raft foundation, is investigated and geotechnically designed here. The effectiveness of this system is demonstrated using the measures total settlement, differential settlement, and rotation. Keywords: Pile raft foundation, differential settlement, total settlement, wind turbin, bearing capacity
Preparing Municipal Solid Waste Emission Inventory and Spatial Distribution of Prayagraj City Using GIS
Authors: Singh Ashish Shankar
Published: September 2021

Abstract: Pollutants in the air are emitted from a variety of sources in metropolitan areas, causing poor air quality. Using a Geographic Information System (GIS), this project attempts to assess municipal solid waste (MSW) burning emissions and prepare a spatial distribution grid for Prayagraj city. PM10, PM2.5, NOx, SO2, and CO emissions were computed using activity data and emission factors using a bottom-up approach. The result from this study shows that emissions for all 5 pollutants PM10, PM2.5, NOx, SO2, CO are 718, 488, 269, and 3771kg/day respectively, where CO is the highest emitted pollutant. The Prayagraj municipal area was divided into grids of 3 km2 area. The spatial distribution plotted for Prayagraj city shows the hotspot grid areas for all 5 air pollutants emission. The hotspot grids for PM10 are P9, P10, P17, P29 and for PM2.5, NOx, SO2, are P9, P10, P17 and for CO are P9, P10, P14, P17, P29. Keywords: PM10, PM2.5, NOX, SO2, CO, Emission Inventory, Spatial distribution, Hotspot grids
Study of the characteristics of the ascending vortex of the cyclone and the concentration of dust along its section
Authors: Lukyanov Alexander V. , Orlov Stanislav M. , Romanenko Boris R.
Published: September 2021

Introduction. Protection of the atmosphere is a social and economic problem inextricably linked with the task of creating comfortable conditions for human life and work. Cyclones are the most typical representatives of dry inertial dust collectors. This work is aimed at reducing energy consumption when cleaning gas with cyclones.

Materials and methods. In the course of the work, analytical and experimental research methods were applied.

Results. Analytical dependences of the aerodynamics of the ascending cyclone vortex have been obtained, which showed that the ascending vortex has a complex structure and the cyclone is an artificially created spiral structure, akin to such a natural phenomenon as a tornado. The obtained mathematical model was fully confirmed by experimental studies.

Conclusions. The studies carried out show that the ascending vortex in the cyclone has a structure consisting of two zones. In the first zone (core), the force of the radial pressure gradient exceeds the centrifugal force, and the dust rushes towards the cyclone axis. In the second, the centrifugal force exceeds the force of the pressure gradient, and the dust is thrown to the periphery. The obtained theoretical model will make it possible to reasonably choose methods for more rational use of the expended energy and increasing the efficiency of cyclones.
Determination of modeled costs at sewage treatment plants in the case of different sequences of treatment
Authors: Makisha Nikolay A.
Published: September 2021

Introduction. The article considers the definition of the key components of operating costs at wastewater treatment plants with a capacity of 1 to 100 thousand cubic meters per day by modeling using specialized software.

Materials and methods. In the study, two technological cleaning schemes were investigated — the conventional line-up with biological aeration reactor and secondary clarifier and the scheme of biological aeration reactor with submerged membrane bioreactor for sludge separation. The other structures for the two facilities were identical. Since it was important to obtain results that could be used at real facilities, the values of concentrations of major pollutants typical for urban wastewater before treatment, as well as technological parameters of operation, were used as initial data for calculations.

Results. As the results of calculations, the values of concentrations of pollutants in wastewater after treatment using both technological schemes and the values of the required volumes for the arrangement of biological treatment facilities and the area occupied by them were obtained and analyzed. Operating costs were considered in terms of electricity costs for the operation of biological treatment facilities and treatment facilities in General, as well as the specific cost of electricity for treatment 1 m3 of wastewater. In addition, the cost of purchasing membrane modules was calculated, which can be classified as operational due their replacement frequency of approximately every 7–10 years.

Conclusions. The results of the study showed that application of membrane technologies at the stage of secondary treatment could have a significant potential for the reconstruction of wastewater treatment plants in conditions of increased productivity and limited opportunities for expanding the area.
CHARACTER EDUCATION IN THE ACEHNESE IDIOMS OF KUALA BATEE COMMUNITY OF SOUTHWEST ACEH
Authors: Sanusi Sanusi
Published: September 2021

This study is entitled "Character Education in the Acehnese Idiom in the Kuala Batee Community of Southwest Aceh”. The Acehnese idiom was used as a support in advising and as a means of maintaining existing norms in the society. A Society is one of the most influential molders of character education because of its interactions. The values of traditional culture are recognized by all levels of the society in the regions and nationalities that become national identities. Not only culture, local languages also need to be used in daily interactions in society so that they do not experience a serious decline, which will eventually disappear over the time. In this case, the Acehnese Idiom became a medium to spread the value of character education to the next generation. The purpose of this study is to describe the Acehnese expressions that contain the values of character education in the community of Kuala Batee Southwest Aceh. The method of this research is a descriptive qualitative. Interview was used as an instrument. In this study, 8 subjects are chosen using purposive sampling that consist of tuhapheut and village elders in the community. The location of this study is in Kuala Batee District, Southwest Aceh.  There are 18 character values in the Acehnese Idiom in the community of Kuala Batee, Southwest Aceh which consists of; religious, honest, tolerance, discipline, hard work, creative, independent, democratic, curiosity, national spirit, love of the homeland, respect for achievement, friendly/communicative, love peace, love to read, care for the environment, social care and responsibility. The expressions found in the Kuala Batee community are in the form of one line, two lines, three lines and four lines. The Acehnese idiom in the community of Kuala Batee Southwest Aceh is in the oral form which has its own meaning and use as an advice relating to divinity, self, others and the environment. Based on the above conclusions, the author suggests the community to preserve the Acehnese idiom so that it becomes a legacy for the next generation. To the government, it is hoped that they will support to publish references related to Acehnese idioms and other types of folklore related to Acehnese culture so that they can add references to other studies.
LAFAZ QALB, SHADR DAN FU'AD DALAM AL-QUR'AN
Authors: Suarni Suarni , Mawaddah Irda
Published: September 2021

Keunikan dan keistimewaan al-Qur'an dari segi bahasa merupakan kemukjizatan yang ditunjukkan kepada masyarakat Arab sejak 15 abad lalu. Setiap pemilihan kosakata mempunyai nilai falsafah bahasa tersendiri. Kehalusan bahasa dan uslub al-Qur'an yang menakjubkan terlihat dari balaghah dan fashahahnya, baik yang konkrit maupun abstrak dalam mengekspresikan dan mengeksplorasi makna yang dituju. Dalam pemilihan kata, al-Qur'an kadang menggunakan beberapa kata yang memiliki arti sama dalam bahasa Indonesia, sehingga tampak ada inkonsisten dalam kata-kata yang digunakannya. Inilah yang melatarbelakangi pembahasan ini, tepatnya pada lafadz qalb, shadr dan fu’ad yang ketiga kata tersebut sering diartikan dengan satu arti yaitu hati. Penelitian ini menggunakan metode maudhu’i berupa riset kepustakaan (library research). Dalam al-Qur'an, lafaz qalb, shadr dan fu’ad mempunyai makna yang hampir berkaitan, namun dengan konteks dan tujuan yang berbeda. Qalb tertuju pada hal-hal yang bersifat immateri yang bersifat psikis, sifat ruhani yang mampu memahami dan penentu baik-buruknya sebuah jiwa karena semua bergantung pada baik-buruknya keadaan qalb. Shadr disebut dengan dada adalah wadah di mana qalb bersemayam, sehingga penggunaan kata shadr dalam al-Qur'an merupakan kinayah bagi sesuatu yang ada di dalamnya yaitu qalb. Adapun fu’ad disebut sebagai hati yang bersifat jujur (hati nurani) dan merupakan potensi qalb, tempat di mana telah mencapai keputusan yang mantap atau sesuatu yang telah terikat, tepatnya fu’ad adalah wadah keyakinan.

KRITIK KONTEKSTUALISASI PEMAHAMAN HADIS M. SYUHUDI ISMAIL
Authors: Siregar Idris
Published: September 2021

In hierarchically, hadith is the source of the second law after the Holy Quran because it serves as al-bayan (explanatory) to the laws contained in the Holy Quran. In understanding hadith, must know the condition of sanad and matan. Exceptly, it must also know the circumstances that were happening when the hadith was issued (background), and then also need to know about the properties of hadith, whether universal, temporal or local. All that is need to get a proper understanding of the hadith. One of Indonesian scholars who always analyze the function of the prophet is M. Syuhudi Ismail in his book Hadis Nabi yang Tekstual dan Kontekstual: Telaah Ma’ani al-Hadits tentang Ajaran Islam yang Universal, Temporal dan Lokal. In this case I see there are some hadiths that are less precise with the analysis of M. Syuhudi Ismail contextual, such as women's issues became head of state or President. Therefore i wants to criticize it contextual.

Published: September 2021

This article is a research about the word of layta in the Qur’an. Generally, the using of the word of layta in the Qur'an referred to unbelievers when expressing their remorse in the afterlife. However, there are Qur'an verses that use the word of layta referred to the believers and in the context of the world. Due to the variations of this designation, the author feels the need for more in-depth research related to the using of the word of layta in the Qur'an. This research is library research, using content analysis techniques in processing data. The data sources that the authors refer to are Balâghah books such as al-Balâghat al-Wâdhihah, and the book of interpretation. The results of this study can be concluded that the word of layta is mentioned fourteen times in the Qur'an, with three speakers: believers, unbelievers and hypocrites. The meanings that indicated by this word are regret, delusion and good wishes. Then, these meanings are connected with psychology. And the result is that if the pronunciation of this word relies on the believer, it shows a positive meaning, such as a sense of empathy. Conversely, if it relies on other than believers, it has a negative meaning.Abstrak: Tulisan ini merupakan penelitian terhadap lafal layta yang terdapat dalam al-Qur’an. Umumnya, penggunaan lafal layta dalam al-Qur’an disandarkan kepada orang-orang kafir ketika mereka mengungkapkan penyesalannya di akhirat. Namun, ada ayat al-Qur’an yang menggunakan lafal layta dengan disandarkan kepada orang mukmin dan dalam konteks dunia. Berangkat dari adanya variasi penyandaran lafal tersebut, penulis merasa perlu meneliti lebih dalam terkait penggunaan lafal layta di dalam al-Qur’an. Penelitian ini bersifat kepustakaan (library research), dengan menggunakan teknik analisa isi (content analysis) dalam mengolah data. Sumber data yang penulis rujuk adalah kitab-kitab Balâghah seperti  al-Balâghat al-Wâdhihah dan kitab-kitab tafsir. Hasil dari penelitian ini dapat disimpulkan bahwa lafal layta disebut sebanyak empat belas kali dalam al-Qur’an, yang disandarkan kepada tiga subjek, yaitu mukmin, kafir dan munafik. Makna yang ditunjukkan lafal layta adalah penyesalan, angan-angan dan harapan yang baik. Selanjutnya, makna-makna tersebut dihubungkan dengan ilmu psikologi. Maka, hasil yang didapatkan adalah jika pengucapan lafal ini disandarkan kepada orang mukmin, ia menunjukkan makna positif, seperti rasa empati. Sebaliknya, jika disandarkan kepada selain mukmin, maka ia bermakna negatif.
PENAFSIRAN SURAT AL-DHUHA MENURUT AL-BAIDHAWI DAN BINTU AL-SYATHI’

The Alquran is a guide for every human being, to understand the meaning contained herein it takes a science that is the interpreter science. There are different interpretations because of the methods, features and shapes used by a mufassir, and because the other is the period in which a mufasir lives, or other names are classical and contemporary periods, a period is a factor in the difference of interpretations, because of the many contemporary problems or the absence of ancient evidence. The method that researchers use is a descriptive analytical method of collecting existing data sources and then being properly analyzed, whereas the data source that researchers refer to are the interpretive books themselves, here researchers use interpresir Anwaru al-Tanzil wa Asraru al-Ta’wil as the classic interpretive reference, to the interpretation of contemporary researchers refer to Tafsir al-Bayani li al-Qur`an al-Karim treatise for Bintu al-Syathi. One example that became a difference in interpretation was lafadz taqhar surah al-Dhuha serves 9, Baidhawi interpret by the reach that you possess his possessions is because of his weaknesses, whereas Bintu al-Syathi interprets not arbitrary not to give property to them, but there is a treatment that offends them like harsh words, a cynical stare which the deed is committed without any deliberate measure.Abstrak: Al-Qur`an merupakan pedoman bagi setiap manusia. Untuk memahami makna yang terkandung di dalamnya, maka dibutuhkan sebuah ilmu yaitu ilmu tafsir. Adanya perbedaan penafsiran disebabkan karena metode, corak dan bentuk yang dipakai oleh seorang mufasir. Sebab lainnya adalah masa di mana seorang mufasir hidup, atau sebutan lainnya adalah periode klasik dan periode kontemporer. Masa menjadi salah satu faktor terjadi perbedaan penafsiran, karena banyaknya permasalahan di zaman kontemporer ini atau hal-hal lain yang tidak didapati di zaman terdahulu. Seperti yang terlihat dalam tulisan ini, yaitu perbedaan penafsiran pada surat al-Dhuha. Metode yang peneliti gunakan adalah analitis deskriptif yaitu mengumpulkan sumber-sumber data yang ada, lalu dianalisa secara tepat. Sumber data yang menjadi rujukan adalah kitab-kitab tafsir, khususnya Tafsir Anwaru al-Tanzil wa Asraru al-Ta’wil sebagai rujukan tafsir klasik. Untuk tafsir kontemporer merujuk kepada Tafsir al-Bayani li al-Qur`an al-Karim karya Bintu al-Syathi’. Salah satu contoh yang menjadi perbedaan penafsiran pada surat al-Dhuha (93): 9 adalah pada lafal taqhar. Al-Baidhawi menafsirkan dengan “janganlah kamu menguasai hartanya dikarenakan kelemahannya”, sedangkan Bintu al-Syathi’ menafsirkan bukan kesewenang-wenang tidak memberikan harta terhadap mereka, tetapi ada perlakuan yang menyakiti hati seperti perkataan yang kasar, tatapan sinis yang mana perbuatan tersebut dilakukan tanpa unsur kesengajaan.

Analisis Hubungan Kecepatan Rerata Terhadap Kecepatan Permukaan Untuk Penentuan Kekasaran Dasar Pada Aliran Saluran Terbuka
Authors: Widayanti D.A.
Published: September 2021

Kecepatan aliran suatu tampang saluran dapat digunakan untuk menentukan nilai n-Manning, dimana nilai n-Manning merupakan koefisien yang merepresentasikan kondisi kekasaran hidraulik suatu penampang saluran. Dikarenakan tidak mudahnya menentukan nilai n- Manning secara akurat di lapangan, pada penelitian ini dilakukan analisis hubungan antara kecepatan aliran rerata tampang (U) dengan kecepatan aliran titik (u(bi,dj)) dengan d = 0.0D; 0.1D; 0.2D dan 0.6D untuk penentuan nilai n-Manning pada suatu tampang saluran, dimana bi adalah koordinat lebar saluran, dj adalah koordinat kedalaman aliran, D adalah kedalaman aliran. Pertama-tama dilakukan analisis rasio antara kecepatan aliran rerata tampang (U) terhadap kecepatan aliran titik (u(Vi,dj)) untuk beberapa jenis kondisi saluran yang disebut nilai koefisien k; nilai tersebut dianalisis pada beberapa posisi pengukuan arah transversal saluran, b/B. Jenis saluran yang digunakan terdiri dari saluran alami/sungai (Sungai Opak bagian tengah, Sungai Opak bagian hulu, Sungai Kuning), Saluran Mataram berbelok, Saluran Mataram tidak seragam, Saluran Laboratorium Berbelok, dan Saluran Laboratorium lurus. Hasil analisis nilai k tersebut selanjutnya digunakan untuk perhitungan nilai n-Manning. Hasil perhitungan nilai n-Manning tersebut selanjutnya dibandingkan dengan nilai n- Manning dari hasil perhitungan rumus empirik. Hasil nilai k yang diperoleh pada d = 0.0D; 0.1D; 0.2D dan 0.6D untuk data di tepi saluran (b/B = 0,25) rentang nilai yang dihasilkan lebih besar dibandingkan rentang nilai k di tengah saluran (b/B = 0,50). Nilai k pada bagian tengah saluran nilai yang dihasilkan lebih stabil atau relatif sama di semua jenis saluran yang ditentukan. Nilai n-Manning berdasarkan nilai k dan rumus empirik rentang nilai yang dihasilkan cukup dekat, khususnya untuk data di sungai dan Saluran Mataram. Sedangkan untuk data di saluran laboratorium nilai n-Manning berdasarkan rumus empirik lebih kecil dibandingkan nilai n-Manning berdasarkan nilai k.
