Konsep Whole of Government (WoG) Sebagai Solusi Permasalahan Pencemaran Aliran Sungai Dalam Bingkai Politik Hijau (Studi di Sungai Citarum)
Authors: DIAVANO ADAM 
Published: December 2022

Permasalahan pencemaran aliran sungai sangat marak terjadi, hal tersebut terjadi dikarenakan banyaknya masyarakat yang membuang air limbahnya dan sampahnya ke sungai. Oleh sebab itu banyak sungai yang kondisinya tercemar, padahal sungai memiliki peranan yang sangat penting. Sebenarnya sudah ada upaya yang dilakukan oleh pemerintah untuk menjaga kualitas aliran sungai, akan tetapi belum terkoordinir dengan baik. Tanpa adanya koordinasi maka permasalahan pencemaran sungai yang bersifat multi stakeholder tidak akan terselesaikan. Untuk menjawab permasalahan tersebut muncullah konsep Whole of Government, dimana Whole of Government adalah konsep yang berusaha menyatukan keseluruhan elemen dari pemerintah, swasta, dan masyarakat untuk mencapai sebuah tujuan. Dengan karakteristik tersebut, dirasa mampu untuk menjawab permasalahan utama dari pencemaran aliran sungai yaitu koordinasi. Tapi konsep Whole of Government masih sangat sedikit diterapkan untuk menangani permasalahan pencemaran aliran sungai. Minimnya pengimplementasian konsep Whole of Government dalam menangani permasalahan pencemaran aliran sungai, diindikasikan terjadi karena partai politik yang ada belum memasukkan Whole of Government kedalam alternatif cara untuk menangani permasalahan pencemaran aliran sungai. Untuk itu kita dapat meniru konsep Whole of Government yang diterapkan di Sungai Citarum. Dimana pemerintah pusat, pemerintah daerah, POLRI, TNI, dan kejaksaan saling bersinergi dan terintegrasi. Hasilnya Sungai Citarum dapat keluar dari status tercemar berat menjadi sedang
A Continuous-Time-Based MILP Model for Production and Transportation Scheduling in Nonpipelined Wells in Low-Permeability Oil Fields

Published: December 2022

Abstract
The marginal wells in low-permeability oilfields are characterized by small storage size, scattered distribution, large regional span, low production, intermittent production, etc. The production mode of these wells is nonpipeline mode. In our previous work (Zhang et al., 2019), a novel mixed-integer linear programming (MILP) model using a discrete-time representation was presented for the operation scheduling of nonpipelined wells. However, too many discretization time points are required to ensure the accuracy of the model. Even for moderately sized problems, computationally intractable models can arise. The present paper describes a new continuous-time representation method to reformulate this schedule optimization problem. By introducing the continuous-time representation, the binary variables are largely reduced. The solution effect for different model sizes is also investigated. When the model size increases to a certain degree, a feasible solution cannot be obtained within a limited time. The results of a case study originated from a real oilfield in China show that the continuous-time model requires less time to obtain the optimal solution compared to the discrete-time model. In details, considering a same scale problem, the solution based on the continuous-time model saves 52.25% of the time comparing with the discrete-time model. The comparison validates the new model’s superiority.
On the Use of Low-Frequency Distributed Acoustic Sensing Data for In-Well Monitoring and Well Integrity: Qualitative Interpretation
Authors: Haavik Kjetil E. 
Published: December 2022

Summary
Distributed acoustic sensing (DAS) is used to monitor production and injection wells in real time. Here we present theory, data examples, and interpretation of low-frequency (LF)-DAS data acquired on fiber-optic (FO) cables clamped to the production tubing. We show that these data give unprecedented insights into the well and serve as a tool for qualitative analysis of well integrity, well operations, and production. By understanding these data, we show that we, for example, can detect leaks, monitor valve performance, and detect the liquid level in Annulus A.
While in-well DAS’s sensitivity to changes in temperature over time is well known, its sensitivity to pressure and flow at low frequencies has not been well understood. Here, we show that the LF-DAS response is multifaceted and dependent on the fluid content of the different tubulars in a well, the casing, and completion design, and if a valve is open or closed. Very often a pressure response is seen due to an accompanied temperature effect; while this complicates the overall picture for quantitative data analysis, qualitative interpretation can be made simple. Understanding these processes in LF-DAS data forms the foundation for developing automated interpretation algorithms in the future.
Temperature-Triggered Release of Chromium Chloride from Nanocapsules for Controlled Burst Release and Gelation of Hydrolyzed Polyacrylamide to Plug High-Permeability Channels

Published: December 2022

Summary
Chromium(III) (Cr3+)-hydrolyzed polyacrylamide (HPAM) gels have been applied extensively as blocking agents for sweep efficiency improvement. Previous studies focused on delaying the gelation time and ignored the diffusion of the crosslinkers during the transportation process. The gelation time of Cr3+-HPAM was too long to be controlled. This study systematically describes a novel approach of using thermoresponsive nanocapsules to precisely control the release of Cr3+. The nanocapsules are successfully prepared by a controlled nanoprecipitation of hydrophobic polymers [poly (methyl methacrylate)] (PMMA) and Pluronic® P-123 onto stable aqueous Cr3+ solution nanodroplets. The stable aqueous nanodroplets are obtained by double inverse miniemulsions with oil-soluble surfactant Span® 80. The nanoprecipitation occurs when heating the mixture at 50℃, which leads to the evaporation of solvent and precipitation of the PMMA into the interface of the aqueous droplets to form the shells. Pluronic P-123 is introduced to stabilize the double miniemulsion and enhance the precipitation efficiency of the shell polymer during the fabrication process. The fabricated nanocapsules show a size range from 211.9 to 297.2 nm depending on the feed contents of the Cr3+. The thermoresponsive function of Pluronic P-123 is studied and applied as a temperature-trigger on the shell. Gelation results show that the thermoresponsivity of Pluronic P-123 dominates the release rate rather than the diffusion rate through PMMA, which could be used to shorten the gelation interval time.

Published: December 2022

Abstract
Photoacoustic imaging techniques requires the knowledge of the speed of sound distribution of background which is not available prior to imaging process. The estimation of SoS in a layered media is a difficult task due to the nonlinearity of the wave propagation. In this work, we proposed a novel Hybrid Focusing Metric (HFM) for accurate image quality assessment in an autofocusing approach to estimate the speed of sound distribution of layered media. In the proposed metric, contrast resolution and spatial resolution information were combined into a novel hybrid focusing metric to enhance the image quality assessment by exploiting intensity-based focusing metrics and pixel count metrics. We have demonstrated that with HFM, the estimation accuracy is increased compared to the state-of-the-art metrics through numerical simulations using k-Wave toolbox.
Creating Measurement-Based Oil and Gas Sector Methane Inventories using Source-Resolved Aerial Surveys
Authors: Johnson Matthew , Conrad Bradley , Tyner David 
Published: December 2022

Abstract

We present a new framework for incorporating aerial measurements into comprehensive oil and gas sector methane inventories that achieves robust, independent quantification of measurement and sample size uncertainties, while providing timely source-level insights beyond what is possible in current official inventories. This “hybrid” inventory combines top-down, multi-pass aerial measurements with bottom-up estimates of unmeasured sources leveraging continuous probability of detection and quantification models for a chosen aerial technology. Notably, the combined Monte Carlo and “mirror-match” bootstrapping technique explicitly considers skewed source distributions and finite facility populations that have not been previously addressed. The protocol is demonstrated to produce a comprehensive upstream oil and gas sector methane inventory for British Columbia, Canada, which while approximately 1.7 times higher than the most recent official bottom-up inventory, reveals a lower methane intensity of produced natural gas (< 0.5%) than comparable estimates for several other regions. Finally, the developed method and data are used to upper bound the potential influence of source variability/intermittency on the overall inventory, directly addressing an open question in the literature. Results demonstrate that even for an extreme case, variability/intermittency effects can be addressed by sample size and survey design and have a minor impact on overall inventory uncertainty.
Impact of climate change on nomadic herders’ livelihoods: a case study of the Bakarwal tribe in the western Himalayas in India

Published: December 2022

Abstract

This study quantifies the impact of climate change on the livelihoods of nomadic herders in the western Himalayas in India, who depend on natural resources for their livelihood, and are herding livestock. In this research paper, we collected primary data from 235 nomadic herders on their perceptions regarding the variables of climate change. We analysed the primary data using factor analysis and found that due to climate change, in the last few decades, nomads have experienced less and untimely rainfall and increased temperature, which ultimately results in the fallen growth of pasture, degraded quality and quantity of pasture, pasture plants being replaced by weedy plants, shrunken harvesting time of pasture, drying of sources of water in later days at winter residence, seasons have changed, experiencing unstable weather, and reduced grazing areas are bringing drought-like situationsin the area. Furthermore, this creates significant challenges in raising livestock with less pasture, and water availability, increased environmental diseaserisk bringing starvation and death of animals, falling the quality and quantity of milk, wool and meat, and loweringthe market price of final goods. This has had a serious impact on the economic activities of nomadic herders in the region. Climate change also forced the nomadic herders in the region to migrate early, which allowed them to face difficulties such as ice over mountain passes, less grass along the paths for grazing, unexpected avalanches, thunderstorms or hailstorms and intense rains on the way to uplands. Finally, this study brings to the notice of policymakers, climatologists, local governments, and animal health departments that climate change is endangering the life of nomadic herders, and we should develop appropriate plans to minimize the loss.

Abstract

Potato (Solanum tuberosum L.) is an important food crop cultivated across the world for its nutritive values and food security. Potato has huge genetic diversity contributed by different cultivars that are grown globally. The objective of this research was to evaluate morphological and genetic variation in potato cultivars grown in Pakistan through sequencing of selected mitochondrial and nuclear genes and some morphological characteristics. Seventeen morphological traits of six different cultivars were analyzed for morphological characterization. All cultivars exhibited variation in their morphological characteristics. DNA fragments of Malate dehydrogenase (~ 940bp) and Beta carotene hydrogenase 2 (~ 1400bp) from nuclear genome and cytochrome c oxidase subunit 2 gene from mitochondrial genome were sequenced. The molecular analysis has revealed the near complete identity among cultivars for Beta carotene hydrogenase 2 and cytochrome c oxidase subunit 2. Sequence analysis of Malate dehydrogenase has revealed the presence of three novel SNPs. An insertion of 13 nucleotide was also present in three cultivars. The cluster analysis has revealed two groups placing Cosmo and Hermes in one group and remaining four varieties in the separate group based on sequence data. Grouping of the cultivars based on morphological traits is different from those based on the genes studied thus showing no direct relation of the said genes with qualitative morphological traits.

Published: December 2022

Abstract

Purpose: To evaluate the repeatability and agreement of two swept-source optical coherence tomographers and Scheimpflug imaging for corneal curvature in healthy subjects.
Methods: Simulated keratometry (SimK), posterior keratometry (Kp), total corneal power (TCP), and total corneal astigmatism(TCA) were measured with CASIA2, Anterion, and Pentacam. Within-subject standard deviation (Sw), repeatability coefficient (RC), coefficient of variation (CoV), and intraclass correlation coefficient (ICC) were used to assess inter-device repeatability. Bland-Altman analysis was performed to determine inter-device agreement.
Results: Three devices showed good repeatability for SimK, Kp, and TCP with all the ICC > 0.980. Pentacam showed the highest repeatability while the CASIA2 revealed the lowest repeatability for SimK and TCP. Anterion and CASIA2 revealed better repeatability for Kp than Pentacam. Pentacam and Anterion showed good repeatability for TCA, whereas the CASIA2 showed moderate repeatability. Three instruments demonstrated good agreement with the maximum absolute 95% Limits of agreement (LoA) of 1.00 D for SimK, Kp, and TCP. Wide LoA were found between for TCA with the maximum absolute 95% LoA ≥0.66 D between the three devices.
Conclusions: Three devices illustrated good repeatability for SimK, Kp, and TCP. Both Anterion and Pentacam showed good repeatability for TCA while CASIA2 displayed moderate repeatability. Good agreement was found for SimK, Kp, and TCP but not for TCA.

Published: December 2022

Abstract
Background: Staphylococcus infections remains a global problem and cause significant morbidity and mortality both in animals and humans. Contaminated meat and paper currency surfaces play a key role in the spread of bacterial infections with antibiotic resistance.
Methods: A cross-sectional study was conducted with the objective of isolation and identification of Staphylococcus species from Ethiopian paper currency notes and raw meat handled by the butcher, restaurant and abattoir workers and to determine antimicrobial susceptibility test. A total of 243 samples (135 raw types of meat and 108 paper currency) were examined by biochemical tests for the presence of Staphylococcus species.
Results: From a total of 243 collected samples, 26.7% and 64.8 % were found positive isolates of raw meats and paper currency notes respectively. An overall prevalence of 43.6%(106) was recorded. The highest prevalence was observed 39(72.2%) in Hermata merkato kebele whereas the lowest was 3 (11.1%) in Ifabula. Variation within the source of the sample was statistically significant (P<0.05). Of these isolates, 30 selected isolates were tested for antibiotic susceptibility test. Thirty(100%) isolates were susceptible to chloramphenicol. There is no isolate that was sensitive to all four selected antimicrobials (Penicillin G, Gentamycin, chloramphenicol, and Tetracycline). Six isolates of meat (50%) were resistant to penicillin G. which indicates its emerging animal and public health problem.
Conclusions: The finding indicated the presence of antibiotics resistance Staphylococcus species contamination of meat and paper currency birr. Awareness creation is paramount important for people working on the food chain to reduce cross contamination of food and prevent foodborne intoxication.

Abstract
Background & Aims: Inflammatory bowel disease (IBD) is becoming more and more popular in the whole wide world. Intestinal epithelial barrier dysfunction is an important step to IBD while the mechanisms are not fully understood. This study aimed to clarify the function of CRL4DCAF2, an E3 ligase, in maintaining intestinal homeostasis.
Methods: Expression of CRL4DCAF2 was evaluated in colon samples taken from IBD patients and healthy people. CRL4DCAF2 conditional knockdown in intestinal epithelial cells (IECs) mice (DCAF2EKD) were constructed. DCAF2EKD and their littermate control (DCAF2EWT) were treated with dextran sodium sulfate (DSS) to induce acute colitis. Transcriptome analysis was performed on inflamed colon samples taken from the mice. Cell cycle molecules were evaluated by real-time PCR while tight junction proteins and apoptosis proteins were examined by immunofluorescence and western blot.
Results: CRL4DCAF2 was significantly decreased in the inflamed IBD epithelium, and low expression of CRL4DCAF2 associated with high recurrence risk. Mouse with DCAF2 specific knockout in IECs suffer from embryonic death. Multiple genes involved in cell proliferation, immune response and gap junction were differentially expressed in inflamed colon from DCAF2EKD compared to DCAF2EWT. Among these, in mice, conditional downregulation of CRL4DCAF2 in the intestinal epithelium induced primarily epithelial damage, increased intestinal permeability and diminished tight junction proteins expression. From in vivo and in vitro cell transfection experiments, we found CRL4DCAF2 promoted the proliferation by promoting p21 ubiquitination and degradation thus releasing its inhibition on G2/M cell cycle. In addition, CRL4DCAF2 can also inhibit IEC apoptosis and advance cell autophagy.
Conclusions: CRL4DCAF2 downregulation in IECs promotes intestinal barrier dysfunction postpones IECs renewal thus made it more Susceptible to inflammation.

Abstract
Soil microbiota can confer fitness advantages to plants and increase crop resilience to drought and other abiotic stressors. However, there is little evidence on the mechanisms correlating a microbial trait with plant abiotic stress tolerance. Here, we report that a class of Streptomyces effectively alleviates the drought and salinity stress by producing new spiroketal polyketide pteridic acid H (1) and its isomer F (2). The bifunctional pteridic acid (pta) biosynthetic gene cluster (BGC), which is also responsible for the biosynthesis of the known antimicrobial elaiophylin, was confirmed by bioinformatic analysis and in vivo CRISPR base editing. Pteridic acids H and F exhibited profound effects in promoting root growth in Arabidopsis at a concentration of 0.5 ng mL-1 (1.3 nM) under abiotic stress, indicating they are a new class of plant stress regulators. Phylogenetic and geographical distribution analysis revealed that the pta BGC was mainly disseminated by vertical transmission and occasional horizontal gene transfer and is widely distributed in numerous Streptomyces in different environments. This discovery reveals a new perspective for understanding plant-Streptomyces interactions and provides a novel, promising approach for utilising beneficial Streptomyces and their secondary metabolites in agriculture to mitigate the detrimental effects of climate change.
Is Capital Income Unfairer than Labor Income: Evidence from Inequality of Opportunity in China
Authors: Zhang Zhipeng , Tang Jie 
Published: December 2022

Abstract
This paper provides a novel perspective to evaluate distributive justice in capital income. Using China Household Financial Survey (CHFS) data from 2013 to 2017, we estimate the inequality of opportunity (IOp) as a share of total inequality for both labor and capital income to determine its ethical fairness. This paper contributes to the literature on IOp by providing a novel perspective from income composition. It also updates the lower-bound of capital income (share) from the household level in China. We find that the distribution of capital income is actually less ethically offensive than labor income by about 50%, despite the more uneven distribution of capital income. The more polarized but fairer distribution of capital income is robust not only in alternative income proxy variables but also across hukou types and regions of residence. The gap between the IOp level in labor and capital income, however, is decreasing over time.
