River Morphological Study of Downstream Paneki River in Palu Watershed Following The Earthquake and Liquefaction Disaster at Central Sulawesi

Abstract An earthquake that struck Central Sulawesi Province in 2018 triggered liquefaction in several locations such as Jono Oge village where the middle stream of Paneki River flows. Liquefaction caused the Paneki River wash in the densely populated settlement became narrower and shallower due to “flowing” material. In response, the Ministry of Public Works and Housing initiates River Improvement and Sediment Control in Paneki River project. The implementation of this project will affect the river’s behaviour, especially its morphological aspects. Therefore, a study of the discharge capacity and morphological analysis due to said project is needed. The study is conducted using numerical model simulation to obtain the river discharge capacity and river morphological changes in form of bed changes. The model simulation result shows the maximum discharge capacity of Paneki river is 259.81m3/s, also the bed upstream and downstream of the river degrade, with consolidation dam - 1 (CD-1) stabilized the river bed upstream of the dam to 2740 m relative to the river outlet. Stabilization due to the position of CD - 2 could be described using the following equation of  y = -1018 ln(x) + 7208.1, the average degradation of the downstream area could be described with y= 0.017x0.6701. Keywords: River morphology, numerical model, bed degradation. Abstrak. Gempa bumi yang melanda Provinsi Sulawesi Tengah pada tahun 2018 memicu terjadinya likuifaksi di beberapa lokasi seperti Desa Jono Oge tempat Sungai Paneki mengalir. Likuifaksi menyebabkan aliran sungai di desa tersebut menjadi sempit dan dangkal akibat material yang “mengalir”. Kementerian Pekerjaan Umum dan Perumahan Rakyat melakukan pekerjaan Perbaikan Sungai dan Pengendalian Sedimen di Sungai Paneki untuk mengatasi dampak liquifaksi, dimana pelaksanaan pekerjaan ini akan mempengaruhi perilaku sungai, terutama morfologinya. Oleh karena itu, studi tentang kapasitas debit dan analisis morfologi sungai karena proyek tersebut perlu diperlukan. Penelitian ini dilakukan dengan menggunakan model numerik untuk mengetahui perubahan morfologi sungai berupa perubahan dasar dan kapasitas debit sungai. Hasil simulasi menunjukkan kapasitas debit maksimum adalah 259,81m3/s, dasar sungai di hulu dan hilir sungai mengalami penurunan, dengan bendungan konsolidasi - 1 (CD-1) menstabilkan dasar sungai di hulu bendung hingga 2740 m relatif dari outlet sungai. Stabilisasi akibat posisi CD - 2 dapat digambarkan dengan persamaan: y = -1018 ln(x) + 7208.1, degradasi rata-rata daerah hilir dapat digambarkan dengan y= 0.017x0.6701. Kata-kata Kunci: Morfologi sungai, model numerik, degradasi dasar sungai

Effects of acute intermittent hypoxia on corticospinal excitability within the primary motor cortex

Purpose Acute intermittent hypoxia (AIH) is a safe and non-invasive treatment approach that uses brief, repetitive periods of breathing reduced oxygen air alternated with normoxia. While AIH is known to affect spinal circuit excitability, the effects of AIH on cortical excitability remain largely unknown. We investigated the effects of AIH on cortical excitability within the primary motor cortex. Methods Eleven healthy, right-handed participants completed two testing sessions: (1) AIH (comprising 3 min in hypoxia [fraction of inspired oxygen ~ 10%] and 2 min in normoxia repeated over five cycles) and (2) normoxia (NOR) (equivalent duration to AIH). Single- and paired-pulse transcranial magnetic stimulations were delivered to the primary motor cortex, before and 0, 25, and 50 min after AIH and normoxia. Results The mean nadir in arterial oxygen saturation was lower (p  0.05). There was no association between arterial oxygen saturation and changes in corticospinal excitability after AIH (r = 0.05, p = 0.87). Conclusion Overall, AIH did not modify either corticospinal excitability or excitability of intracortical facilitatory and inhibitory circuits within the primary motor cortex. Future research should explore whether a more severe or individualised AIH dose would induce consistent, measurable changes in corticospinal excitability

Dhaka city water logging hazards: area identification and vulnerability assessment through GIS-remote sensing techniques

Water logging is one of the most detrimental phenomena continuing to burden Dhaka dwellers. This study aims to spatio-temporarily identify the water logging hazard zones within Dhaka Metropolitan area and assess the extent of their water logging susceptibility based on informal settlements, built-up areas, and demographical characteristics. The study utilizes integrated geographic information system (GIS)-remote sensing (RS) methods, using the Normalized Difference Vegetation Water and Moisture Index, distance buffer zone from drainage streams, and built-up distributions to identify waterlogged zones with a temporal extent, incorporating social and infrastructural attributes to evaluate water logging effects. These indicators were integrated into an overlay GIS method to measure the vulnerability level across Dhaka city areas. The findings reveal that south and south-western parts of Dhaka were more susceptible to water logging hazards. Almost 35% of Dhaka belongs to the high/very highly vulnerable zone. Greater number of slum households were found within high to very high water logging vulnerable zones and approximately 70% of them are poorly structured. The built-up areas were observed to be increased toward the northern part of Dhaka and were exposed to severe water logging issues. The overall findings reveal the spatio-temporal distribution of the water logging vulnerabilities across the city as well as its impact on the social indicators. An integrated approach is necessary for future development plans to mitigate the risk of water logging

The covid-19 learning crisis as a challenge and an opportunity for schools: An evidence review and conceptual synthesis of research-based tools for sustainable change

This paper advances our understanding of how schools can become change agents capable of transforming local practice to address the challenges arising from the Covid-19 pandemic. It presents a novel application of cultural-historical activity theory to reinterpret evidence on widespread learning loss and increasing educational inequities resulting from the pandemic, and to identify scalable transformative learning opportunities through reframing the crisis as a double stimulation. By reviewing evidence of the emerging educational landscape, we first develop a picture of the new ‘problem space’ upon which schools must act. We develop a problem space map to serve as the first stimulus to articulate local challenges. Integrating this problem space with research on professional change, we identify conceptual tools to capture learning gaps and implement pedagogic interventions at scale, in order to enhance schools’ agency in directly addressing the crisis. These tools can act as the second stimulus, enabling educators to address local challenges. We conclude by discussing the Covid-19 educational crisis as a unique stimulus for professional learning and outline the potential for durable shifts in educational thinking and practice beyond the pandemic. We argue that this unprecedented historic disruption can be harnessed as a transformative professional learning opportunity. In particular, we consider how research on professional change offers local, scalable interventions and tools that can support educators in preventing the new insights from ‘slipping away’ post-pandemic. Utilising the notions of boundaries and tool-mediated professional change, we examine the ways in which this disruption generates opportunities to envision alternative futures for equitable learning in school.Author 1: The epiSTEMe project [grant number RES-179-25-0003, PI Prof. K.
