Combined method for calculating the total erosion of channels composed of easily erodible grounds
Authors: Bazarov D , Kan E , Atajanova D 
Published: June 2023

Abstract
Riverbed processes on rivers composed of easily eroded soils differ in intensity. Therefore, deformation calculation methods are needed that take into account the characteristic features of such rivers. These features can be taken into account by introducing into the composition of the initial equations of dependencies reflecting the features of the alluvial regime and the nature of deformations. To this end, based on the analysis of existing empirical dependencies and actual data of the total erosion below the Takhiatash hydro unite (Amu Darya River, Uzbekistan), the structure and type of dependence of the transporting capacity of the stream on the main parameters of the channel and the morphometric dependence of the width of the stable channel on the average depth were selected. The proposed combined calculation method is based on the theoretical equations of deformation (Saint-Venant) and the equation of fluid motion (Bernoulli) and empirical dependencies for determining the average turbidity of the flow and the width of the channel. With the use of these equations, the calculation of the total erosion below the Takhiatash hydrounite on the Amu Darya River was carried out. Comparison of the calculation results and the actual data showed their satisfactory convergence. The proposed method can be applied to calculate channel deformations on rivers composed of easily eroded soils when regulating the flow of retaining structures.

Abstract
The cement industry has a strategic position in the Indonesian economy. The cement industry, which significantly contributes to the environment due to the use of resources and the resulting emissions, faces challenges in environmental sustainability. Composite portland cement uses less clinker composition and is considered more environmentally friendly. This study attempts to find the hotspots of the cement production process by life cycle assessment (LCA) and evaluates several improvement scenarios in which the best available technologies and energy substitution measures are considered. The assessment was carried out using a cradle-to-gate approach. The potential primary environmental impacts of composite portland cement using the EPD method (2018) are global warming potential (GWP) of 601 kgCO2eq, acidification (AP) of 0.928 kg SO2eq, the potential for eutrophication of 0.385 KgPO4eq, the potential for depletion of the ozone layer. of 0.0000043 Kg CFC-11 eq. Calcination is a critical hotspot for tackling climate change. Hotspots or processes with the largest contribution to the impact of GWP are CO2 emissions from clinkerization operations of 84.80%. The biggest potential impact is GWP which has the largest normalised value among other potential impacts. The biggest impact contribution is at the stages of the production process caused by CO2 emissions of 92%. The recommended scenario to reduce the potential impact of GWP is to increase the thermal substitution rate using alternative fuels and carbon capture technology.

Abstract
Spatial plan is a reference in spatial development in Indonesia. One of the information displayed is landslides susceptibility area. Lima puluh kota regency in province of West Sumatra, which is located in the Bukit Barisan mountains, is a landslide-prone area, so that the regional spatial plan (RTRW) document contains a map of landslide susceptibility areas. This study evaluates the accuracy of the landslide susceptibility map contained in the regional spatial plan with landslide events in the regency until 2021, using the overlay method and then examining with the characteristics that affect it. The results of the study show that not all landslide events are in the locations indicated on the map in the spatial plan. It is necessary to improve the information on the landslide susceptibility map on a regional scale which has been based on the InaRisk map published by the BNPB (National Disaster Management Agency) on a small scale. In order to be more accurate with the causal factors, it is needed to improve the method of landslide susceptibility maps at the regional level. The methods that have been heuristic in nature need to be improved with statistical methods.

Authors: Wijayanti Pipit , Hidayati Farida , Zamani Muhammad Zaki 
Published: June 2023

Abstract
Water in karst areas flows deep below the surface due to geological causes, making it difficult to get pure air on the surface. The karst region has passed with drought as a result. In the watershed Kakap Springs, this paper will examine the adaptability of the community to drought. The study area covers seven villages. The evaluation uses a quantitative descriptive method based on human, social, natural, physical, and financial factors. Adaptation capacity in the research area varies with the driving factor is financial. This is because exposure to drought has been going on for a long time and every year, so people have prepared themselves financially. Intensive exposure also causes the distribution of adaptive capacity in each village to be regulated at a moderate level. It is necessary to increase social capacity so that the adaptive capacity of the community becomes higher.
Open-pit coal mining exacerbates urban heat island in Bontang City, Indonesia

Published: June 2023

Abstract
Global energy demand has surged, especially on coal commodities. To accommodate the demand, open-pit coal mining became a faster and cheaper solution, but left a land-use change and degradation. This research tried to examine the impact of open-pit coal mining on urban heat island (UHI) in Bontang city. The study used multitemporal Landsat images (2002 and 2019) to assess land surface temperature. Then, the UHI and non UHI area were calculated and excluded the sea for the calculation. As a result, UHI was only distributed in the centre of Bontang city. In 2019, UHI intensity distributed in the city centre and also occurred in the open-pit coal mining area with the UHI intensity >5°C distributed equally. The UHI intensity in coal mining is higher than the city. The impact was causing discomfort for the people and could lead to health problems due to interaction with air pollution from mining activities. This study concludes mining should be accompanied with restoration to enhance quality of life and other environmental benefits.

Abstract
Robusta Coffee cultivation on Mount Muria at an altitude of 700 masl, which in the last two years, production reached 1,500 tons per year, an increase of 30 percent from the total land area of 2,200 hectares (2019-2021) (seputarmuria.com, 2021)—coffee cultivators by the people whose management serves as life support. Coffee farmers experience marketing problems; they sell raw coffee beans to local intermediaries, and only a tiny portion is processed. Post-harvest processing to make coffee powder ready for consumption traditionally. The strategy to increase the competitiveness of coffee needs to do so through community empowerment based on social enterprise. Data collection methods were field surveys, structured interviews, FGDs, and literature studies. Data analysis described the coffee farming business and the preparation of development strategies using SWOT analysis. The results showed that Lereng Muria coffee farmers carried out vegetative grafting using the top working method: robusta shoots with superior robusta shoots to get new varieties without killing old plants so that production and yields were high. Most farmers grow coffee by utilizing the forest floor and interspersing it with other commodity crops, including pomelo, cloves, teak, and silk tree. After harvests, the coffee beans are dried directly under the sun, go to the mill, and sold to intermediaries. After doing a SWOT analysis, the average IFE value is 0.63, and the EFE value is 1.13. Recommended 12 development strategies to increase competitiveness, including improving the grafting breeding system, strengthening cooperation between farmers and other stakeholders, improving crop sales management, increasing farmers’ knowledge about climate change and pest control, and other strategies.
Non-invasive optical characterization and estimation of Zn porosity in gas tungsten arc welding of Fe–Al joints using CR model and OES measurements

Published: June 2023

Abstract
In this study, we employed a non-invasive approach based on the collisional radiative (CR) model and optical emission spectroscopy (OES) measurements for the characterization of gas tungsten arc welding (GTAW) discharge and quantification of Zn-induced porosity during the GTAW process of Fe–Al joints. The OES measurements were recorded as a function of weld current, welding speed, and input waveform. The OES measurements revealed significant line emissions from Zn-I in 460–640 nm and Ar-I in 680–800 nm wavelength ranges in all experimental settings. The OES coupled CR model approach for Zn-I line emission enabled the simultaneous determination of both essential discharge parameters i.e. electron temperature and electron density. Further, these predictions were used to estimate the Zn-induced porosity using OES-actinometry on Zn-I emission lines using Ar as actinometer gas. The OES-actinometry results were in good agreement with porosity data derived from an independent approach, i.e. x-ray radiography images. The current study shows that OES-based techniques can provide an efficient route for real-time monitoring of weld quality and estimate porosity during the GTAW process of dissimilar metal joints.
Impact of surgical-site infection on health utility values: a meta-analysis
Authors: McFarland Agi M , Manoukian Sarkis , Mason Helen , Reilly Jacqui S 
Published: June 2023

Abstract

Background
Surgical-site infections (SSIs) are recognized as negatively affecting patient quality of life. No meta-analysis of SSI utility values is available in the literature to inform estimates of this burden and investment decisions in prevention.

Methods
A systematic search of PubMed, MEDLINE, CINAHL, and the National Health Service Economic Evaluation Database was performed in April 2022 in accordance with PROSPERO registration CRD 42021262633. Studies were included where quality-of-life data were gathered from adults undergoing surgery, and such data were presented for those with and without an SSI at similar time points. Two researchers undertook data extraction and quality appraisal independently, with a third as arbiter. Utility values were converted to EuroQol 5D (EQ-5D™) estimates. Meta-analyses were conducted using a random-effects model across all relevant studies, with subgroup analyses on type and timing of the SSI.

Results
In total, 15 studies with 2817 patients met the inclusion criteria. Six studies across seven time points were used in the meta-analysis. The pooled mean difference in EQ-5D™ utility in all studies combined was –0.08 (95 per cent c.i. −0.11 to −0.05; prediction interval −0.16 to −0.01; I2 = 40 per cent). The mean difference in EQ-5D™ utility associated with deep SSI was −0.10 (95 per cent c.i. −0.14 to −0.06; I2 = 0 per cent) and the mean difference in EQ-5D™ utility persisted over time.

Conclusion
The present study provides the first synthesized estimate of SSI burden over the short and long term. EQ-5D™ utility estimates for a range of SSIs are essential for infection prevention planning and future economic modelling.

Published: June 2023

Abstract

Background and Aims
Digital collection of patient-reported outcome measures [PROMs] is largely unexplored as a basis for follow-up for patients with ulcerative colitis [UC]. Our aim was to develop a model to predict the likelihood of escalation of therapy or intervention at an outpatient appointment that may be used to rationalize follow-up.

Methods
TrueColours-IBD is a web-based, real-time, remote monitoring software that allows longitudinal collection of ePROMs. Data for prediction modelling were derived from a Development Cohort, guided by the TRIPOD statement. Logistic regression modelling used ten candidate items to predict escalation of therapy or intervention. An Escalation of Therapy or Intervention [ETI] calculator was developed, and applied in a Validation Cohort at the same centre.

Results
The Development Cohort [n = 66] was recruited in 2016 and followed for 6 months [208 appointments]. From ten items, four significant predictors of ETI were identified: SCCAI, IBD Control-8, faecal calprotectin, and platelets. For practicality, a model with only SCCAI and IBD Control-8, both entered remotely by the patient, without the need for faecal calprotectin or blood tests was selected. Between 2018 and 2020, a Validation Cohort of 538 patients [1188 appointments] was examined. A 5% threshold on the ETI calculator correctly identified 343/388 [88%] escalations and 274/484 [57%] non-escalations.

Conclusions
A calculator based on digital, patient-entered data on symptoms and quality of life can predict whether a patient with UC requires escalation of therapy or intervention at an outpatient appointment. This may be used to streamline outpatient appointments for patients with UC.

Authors: Calvert Peter , Kollias Georgios , Pürerfellner Helmut , Narasimhan Calambur , Osorio Jose , Lip Gregory Y H , Gupta Dhiraj 
Published: June 2023

Abstract
Atrial fibrillation is associated with neurocognitive comorbidities such as stroke and dementia. Evidence suggests that rhythm control—especially if implemented early—may reduce the risk of cognitive decline. Catheter ablation is highly efficacious for restoring sinus rhythm in the setting of atrial fibrillation; however, ablation within the left atrium has been shown to result in MRI-detected silent cerebral lesions. In this state-of-the-art review article, we discuss the balance of risk between left atrial ablation and rhythm control. We highlight suggestions to lower the risk, as well as the evidence behind newer forms of ablation such as very high power short duration radiofrequency ablation and pulsed field ablation.

Published: June 2023

Abstract

OBJECTIVES
Perceval sutureless valve has been in clinical use for &gt;15 years. The aim of this study is to report the real-word clinical and haemodynamic performance from the SURE-aortic valve replacement international prospective registry in patients who underwent aortic valve replacement with Perceval valve.

METHODS
From 2011 to 2021, patients from 55 institutions received a Perceval valve. Postoperative, follow-up, and echocardiographic outcomes were analysed.

RESULTS
A total of 1652 patients were included; mean age was 75.3 ± 7.0 years (53.9% female); mean EuroSCORE II was 4.1 ± 6.3. Minimally invasive approach was performed in 45.3% of patients; concomitant procedures were done in 35.9% of cases. Within 30 days, 0.3 and 0.7% valve-related reinterventions were reported. Transient ischaemic attack, disabling and non-disabling strokes were limited (0.4%, 0.4% and 0.7%, respectively). Pacemaker implant was required in 5.7% of patients. Intra-prosthetic regurgitation ≥2 was present in 0.2% of cases, while paravalvular leak ≥2 in only 0.1%. At a maximum follow-up of 8 years, 1.9% of cardiovascular deaths and 0.8% of valve-related reintervention occurred. Among the 10 cases of structural valve deterioration (mean 5.6 ± 1.4 years after implant; range: 2.6–7.3 years), 9 were treated with a transcatheter vale-in-valve implantation and 1 with explant. Mean pressure gradient decreased from 45.8 ± 16.5 mmHg preoperatively to 13.3 ± 5.2 mmHg at discharge and remained stable during follow-up.

CONCLUSIONS
This experience represents the largest prospective real-world cohort of patients treated with Perceval showing that Perceval is a safe and effective alternative to conventional surgical aortic valve replacement, providing favourable clinical and haemodynamic results also at mid-term follow-up.

Published: June 2023

Abstract
Integrated energy systems are one of the potential options for buildings that can reduce emission. In this research study, the energetic and economic performance of a micro-gas turbine combined heating and cooling plant coupled with a solar PV is analyzed for an office building in Iran. For each analysis, two different scenarios have been performed. System sizing parameters defined in a way that renewable to fossil fuel share is correlated to plant performance and economy. To model the studied system, a time-dependent method is used, which is the inherent characteristic of renewable energies. The renewable energies used here are solar heaters and solar panels. Contours of Net Present Value (NPV) are evaluated as a function of solar heating share and different economic parameters. In addition, optimal system sizing for a typical building is obtained and the results are provided. Effect of various major parameters shows that under the current condition and despite the supportive incentive for renewable energies, strategies and plans even without solar energy are not economically viable due to the high discount rates. In addition, results provide that, in reasonable and normal discount rate, fuel and grid electricity prices, governmental subsidization for conventional combined heat, and power (CHP) and combined cooling, heat, and power(CCHP) is not necessary, and only in this condition solar electricity selling price (i.e. governmental support program) is effective to increase renewable penetration. The results show that if the interest rate is less than 5%, the NPV becomes positive. Also, when the electricity price reaches $0.07/kWh or higher, the NPV becomes positive.
