Published: October 2023

Abstract
Domestic waste generation in Temanggung Regency is about 182,562.96 ton/year contain 51,75% of organic waste, where this organic waste has the potential to be processed into compost. As an alternative method that can be used to process organic waste is the open bin composter method. The data used in this study is secondary data that taken from Dinas Perumahan Rakyat, Kawasan Permukiman, dan Lingkungan Hidup Kabupaten Temanggung in 2022, this data contain measurements of weight, volume, and composition of waste. From this data, the weight of waste that can be composted, volume of organic waste that composted, and the weight of compost can be calculated. From the calculation results, the area that needed for composting area is 20,8 m2, and open bin composter method can process 12.11 m3/day of organic waste to 6.1 m3/day of compost or equal with 1376 kg/day.
The Future of Carbon Dioxide Emission in Indonesia: Does Deforestation Matter?
Authors: Setyadharma A , Oktavilia S , Wahyuningrum I F S , Rosalia A C T 
Published: October 2023

Abstract
Indonesia is a country with one of the highest rates of deforestation in the world. Ten million hectares of main forests in Indonesia had disappeared in the past two decades and 71% of trees in natural forests in Indonesia have been cut during 2013 to 2021. It is estimated that 10% of the CO2 emissions triggered by human actions are from deforestation. Since high CO2 emissions is a negative externality, it will become a burden to society if this problem exists. One of the possibilities to reduce the CO2 emissions problem is through the protection of the forests. Since the presence of forests is important to absorb the carbon produced by human activities, this study tries to find the fact whether there is an impact of deforestation on CO2 emissions in Indonesia by using econometrics modelling. This study applies Dynamic Ordinary Least Square (OLS) method to examine the impact of deforestation on CO2 emissions. Two models are set with two different data as the representation of deforestation variable. First data is forest area coverage as the independent variable, and the second data is the annual deforestation rate as the independent variable, this study uses CO2 emissions as the dependent variable. The results of both models confirm solid evidence that deforestation is contributing to higher level of CO2 emissions in Indonesia. In term of policy implications, some suggestions for the Indonesian government are (1) enforces reforestation as it is the best way to prevent deforestation, (2) applies more strict punishment for illegal logging, and (3) promotes inclusive and sustainable forest management.
Climate Justice in Indonesian Environmental Protection: Past, Present and Future Challenges
Authors: Arifin R , Rodiyah R , Wulansarie R 
Published: October 2023

Abstract
Climate justice is an increasingly relevant topic in today’s world, as climate change and its impacts continue to affect vulnerable communities disproportionately. This research aims to examine the concept of climate justice, its various dimensions, and the challenges and opportunities associated with achieving it. The paper begins by defining climate justice, which is based on the principle that those who are least responsible for climate change are the ones who are most affected by it. It argues that climate justice should be viewed not only as a moral issue but also as a legal and political one. The paper explores the different dimensions of climate justice, including distributive, procedural, and transformative justice. Distributive justice refers to the fair distribution of the benefits and burdens of climate change mitigation and adaptation efforts. Procedural justice concerns the fair and inclusive decision-making processes that involve affected communities in climate action. Transformative justice involves the fundamental changes needed in society to address the root causes of climate change and promote a more sustainable and just future. The paper also examines the challenges and opportunities associated with achieving climate justice, including the need for political will, the role of international cooperation, and the importance of grassroots activism. It concludes by highlighting the urgency of addressing climate change and the need for a holistic approach that prioritizes the well-being of all communities, especially those most vulnerable to its impacts.
Graphene/aluminum oxide interfaces for nanoelectronic devices

Published: October 2023

Abstract
In this work, we study theoretically and experimentally graphene/aluminum oxide interfaces as 0D/2D interfaces for quantum electronics as the nature of the interface is of paramount importance to understand the quantum transport mechanism. Indeed, the electronic transport is driven either by a channel arising from a strong hybridization at the interface, or by tunneling across a van der Waals interface, with very different electric characteristics. By combining electronic spectroscopy and scanning microscopy with density functional theory calculations, we show that the interface is of weak and van der Waals nature. Quantum transport measurements in a single electron transistor confirm this result. Our results provide a first insight into the interfacial properties van der Waals materials based single electron device, and the key role played by the control of the interface states. The weak van der Waals coupling reported is promising for single electron device, where the control of the environmental charges is known to be a key challenge towards applications. Moreover, the unique vertical device architecture, enabled by the dual role of graphene including its vertical electric field transparency, opens the doors for a new class of single electron devices with higher scaling capability and functionalities. This work paves the way to new atomic environment control in single electron device.

and the space is contractible. This form of good cover was introduced by K. Tanaka in 2021. The focus here is on intersecting path cycles (sequences of paths attached to each other in vortexes with nonempty interiors) that form a path nerve. A path nerve results from the nonvoid intersection of a collection of path cycles. The geometric realization of a path cycle is a 1-cycle. A 1-cycle is a finite sequence of path-connected 0-cells (vertexes) with no end vertex and with a nonvoid interior. A 1-cycle has the structure of a path cycle in which sequences of paths are replaced by edges.

Pitfalls of using polymerase chain reaction–based assays for JAK2 and CALR exon 9 variant testing in myeloproliferative neoplasms: Knowing when to go the extra mile!
Authors: Krishnamurthy Kritika , Chai Jiani , Wang Yanhua , Naeem Rizwan , Goldstein D Yitzchak 
Published: October 2023

Abstract

Objectives
The BCR::ABL1 negative myeloproliferative neoplasms are sequentially tested for JAK2 p.V617F, followed by CALR exon 9 pathogenic variants. Historically, these variants were thought to be mutually exclusive. However, recent reports indicate coexisting JAK2 p.V617F and CALR exon 9 somatic variants.

Methods
Analysis of JAK2 p.V617F and CALR exon 9 variant was performed by polymerase chain reaction (PCR)–based assays. Subsequent testing was performed on the Genexus integrated sequencer (ThermoFisher) using the Oncomine myeloid assay GX v2.

Results
CALR exon 9 variants were positive in 3 cases, while 2 were positive for JAK2 p.V617F on PCR-based assays. Next-generation sequencing confirmed the JAK2 P.V617F status in all cases. CALR variants resulting in in-frame deletions were identified in 2 cases at a variant allele frequency of 52.16% and 50.91%, while the third case had an intronic CALR variant c.-48G&gt;A at a variant allele frequency of 51.1%. Thus, CALR variants in all 3 cases were interpreted as potentially germline. Of the 228 cases that underwent JAK2 p.V617F and CALR cotesting in the past 2 years, only these 2 cases were positive for both JAK2 p.V617F and CALR exon 9 variants.

Conclusions
These cases highlight the importance of understanding the pitfalls of molecular techniques in current practice.
A tip-predominant distribution of villous intraepithelial lymphocytes is not specific to celiac disease in children with Marsh I lesions

Published: October 2023

Abstract

Objectives
To assess if the distribution of villous intraepithelial lymphocytes (IELs) in a pediatric cohort with Marsh I histopathology is specific to celiac disease (CeD).

Methods
Multicenter, retrospective case-control study between January 2001 and December 2019 in children (&lt;18 years) with and without CeD with intraepithelial lymphocytosis and normal villous architecture. Pathology specimens were reviewed by 2 study pathologists who were blinded to the final diagnosis. Morphologic features (villous height to crypt depth ratio [Vh:Cd]) and IELs in the villous tip, top, or bottom half of the villus were quantified.

Results
Of the 97 children with Marsh I histopathology identified during the study period, 63 were excluded due to an insufficient number of well-oriented villous-crypt complexes or a Vh:Cd less than 2. Villous IELs were measured in 34 cases (14 CeD, 20 non-CeD controls). There was no difference between the non-CeD and CeD groups in the mean IELs at the villous tip (14.0 ± 7.1 vs 11.7 ± 6.0, P = .31), top (46.4 ± 18.4 vs 38.3 ± 10.8, P = .11), or bottom (29.8 ± 16.8 vs 28.5 ± 12.8, P = .80) half of each villus, respectively.

Conclusions
The distribution of IELs in Marsh I lesions is not specific for CeD.
Transpositioning: Translanguaging and the Liquidity of Identity
Authors: Wei Li , Lee Tong King 
Published: October 2023

Abstract
This article seeks to address the ever-expanding and shifting communicative demands of ‘liquid modernity’ by focussing on two key issues: the need to reconceptualize language and communication as a consequence of the diversification of media and resources people draw upon to meet these demands; and the need for a new analytical framework to capture how people perform multiplex roles simultaneously and spontaneously through dynamic and adaptive communicative practices. We do the former through further elaboration of the scholarship on translanguaging and the latter with a new concept of transpositioning. We argue that the latter is enabled by translanguaging practices and is a necessary capacity participants in the social life of liquid modernity need to develop in order to deal with everyday communicative demands. We develop the concept with analysis of two examples of lived experiences of multilinguals and explore the theoretical and methodological implications for applied linguistics.
Integrative taxonomy and evolutionary history reveal cryptic diversity in Myotis riparius (Chiroptera: Vespertilionidae)
Authors: Novaes Roberto Leonan M , Cláudio Vinícius C , Wilson Don E , Weber Marcelo M , Weksler Marcelo , Moratelli Ricardo 
Published: October 2023

Abstract
Myotis riparius is an insectivorous bat species widely distributed in the Neotropics with evident geographical variation in morphological traits. We conducted an integrative study using mitochondrial DNA, qualitative and quantitative morphology, and current and past species distribution models to investigate the variation, population structure, and distributional limits within M. riparius populations. Phylogenetic inferences indicated that M. riparius is monophyletic, and populations are divided into geographically structured clades that split during the middle Pleistocene. There is no shared haplotype between geographical populations and strong evidence of partial restriction in gene flow. Morphological and morphometric variations revealed subtle distinctions among different populations, but little correspondence with molecular analysis. The distribution models indicated that M. riparius is associated with forest environments, with discontinuity between populations from South American ecoregions. Past distribution modelling, however, indicated that M. riparius had a larger distribution range in the Last Glacial Maximum than currently. Results of modelling and genetic analyses indicated that M. riparius consisted of a large, widespread, and panmictic (meta)population until the middle Pleistocene, when environmental changes driven by climatic dynamics fragmented and isolated the populations. Myotis riparius is here considered a complex of at least four allopatric and parapatric cryptic evolutionary units.
Haploid androgenetic development of bovine embryos reveals imbalanced WNT signaling and impaired cell fate differentiation
Authors: Aguila Luis , Nociti Ricardo P , Sampaio Rafael V , Therrien Jacinthe , Meirelles Flavio V , Felmer Ricardo N , Smith Lawrence C 
Published: October 2023

Abstract
Haploid embryos have contributed significantly to our understanding of the role of parental genomes in development and can be applied to important biotechnology for human and animal species. However, development to the blastocyst stage is severely hindered in bovine haploid androgenetic embryos (hAE). To further our understanding of such developmental arrest, we performed a comprehensive comparison of the transcriptomic profile of morula-stage embryos, which were validated by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) of transcripts associated with differentiation in haploid and biparental embryos. Among numerous disturbances, results showed that pluripotency pathways, especially the wingless-related integration site (WNT) signaling, were particularly unbalanced in hAE. Moreover, transcript levels of KLF4, NANOG, POU5F1, SOX2, CDX2, CTNNBL1, AXIN2, and GSK3B were noticeably altered in hAE, suggesting disturbance of pluripotency and canonical WNT pathways. To evaluate the role of WNT on hAE competence, we exposed early Day-5 morula stage embryos to the GSK3B inhibitor CHIR99021. Although no alterations were observed in pluripotency and WNT-related transcripts, exposure to CHIR99021 improved their ability to reach the blastocysts stage, confirming the importance of the WNT pathway in the developmental outcome of bovine hAE.
Expanding access to telehealth in Australian cardiac rehabilitation services: a national survey of barriers, enablers, and uptake
Authors: Thomas Emma E , Cartledge Susie , Murphy Barbara , Abell Bridget , Gallagher Robyn , Astley Carolyn 
Published: October 2023

Abstract

Aims
Cardiac rehabilitation (CR) is traditionally delivered in-person; however, the COVID-19 pandemic provided impetus for alternative offerings such as telehealth. We investigated uptake, barriers, and enablers in a national survey during the pandemic in Australia.

Methods and results
We surveyed CR programmes between April and June 2021 using professional association networks. The anonymous online questionnaire addressed programme characteristics, COVID-19 impacts, and barriers to and enablers of telehealth use. Open-text responses were coded and presented as themes. In total, there were responses from 105 programmes (33% response rate). All states and geographical areas were represented. The use of every modality of telehealth care (telephone, video conferencing, text messaging, and web-based) increased significantly during and after COVID with a strong preference for telephone (85% of services). Respondents perceived video (53%) and telephone (47%) formats as safe and effective for delivering CR. The most common barriers to telehealth were difficulties conducting assessments and reduced engagement with patients. Prominent enablers were increased reach and reduced patient barriers to CR access.

Conclusion
Telehealth use by CR programmes increased during the peak pandemic period. However, additional support is required to ensure that telehealth services can be maintained. There is considerable potential to increase the reach of CR by embedding telehealth into existing models of care.
