Rosacea is a common chronic inflammatory skin disease with a fluctuating course of excessive inflammation and apparent neovascularization. Microbial dysbiosis with high density of B. oleronius and increased activity of kallikrein 5, which cleaves cathelicidin antimicrobial peptide, are key pathogenic triggers in rosacea. However, how these events are linked to the disease remains unknown. Here, we show that type I interferons produced by plasmacytoid dendritic cells represent the pivotal link between dysbiosis, the aberrant immune response, and neovascularization. Compared to other commensal bacteria, B. oleronius is highly susceptible and preferentially killed by cathelicidin antimicrobial peptides leading to enhanced generation of complexes with bacterial DNA. These bacterial DNA-complexes but not DNA-complexes derived from host cells are required for cathelicidin-induced activation of plasmacytoid dendritic cells and type I interferon production. Moreover, kallikrein 5 cleaves cathelicidin into peptides with heightened DNA-binding and type I interferon-inducing capacities. In turn, excessive type I interferon expression drives neoangiogenesis via IL22 induction and upregulation of the IL22 receptor on endothelial cells. These findings unravel a novel pathomechanism, which directly links hallmarks of rosacea to the killing of dysbiotic commensal bacteria with induction of a pathogenic type I interferon-driven and IL22-mediated angiogenesis.
The 3d twisted index and wall-crossing
Authors: Bullimore Mathew , Ferrari Andrea , Kim Heeyeon
Published: June 2022

We study the twisted index of 3d \mathcal{N}=2𝒩=2
supersymmetric gauge theories on S^1 \times \SigmaS1×Σ
in the presence of a real FI parameter deformation. This parameter
induces a 1d FI parameter for the effective supersymmetric quantum
mechanics on S^1S1.
Using supersymmetric localisation, the twisted index can be expressed as
a contour integral. We show that the contour prescription is modified in
the presence of the 1d FI parameter, leading to wall-crossing phenomena
for the twisted index. In particular, we derive a general wall-crossing
formula for abelian gauge theories. We also examine the origin of
wall-crossing as change of stability condition in the algebro-geometric
interpretation of the twisted index. These ideas are illustrated for
abelian theories with \mathcal{N}=4𝒩=4
supersymmetry and in a non-abelian example that reproduces wall-crossing
phenomena associated to moduli spaces of stable pairs.

AbstractThis study aims to determine the calcium balance in undernourished rats fed with inulin-enriched MOCAF-based diet. Twenty-seven Sprague Dawley male rats at post-weaning age were classified into 1 normal control groups and 8 undernourished groups. The undernourished rats were conditioned for one month then followed by intervention with MOCAF-based diet for another one month. Calcium analysis was performed on the urine, feces, and tibial bones of rats.  Data of calcium were processed using One Way Anova test followed by Post Hoc Duncan to determine mean differences between groups. The results showed that calcium absorption, calcium retention, and calcium bioavailability between groups differed significantly (p0.05). The highest calcium absorption and calcium retention were found in the protein-energy-deficient rats fed Manggu MOCAF with inulin (KEP M2 = 97.47 ± 0.39% and 97.4 ± 0.4%) respectively. Bioavailability of calcium was higher in the group of undernourished rats fed with MOCAF-based diet. The highest level of calcium of the tibia was found in the protein-deficient rats fed Mentega MOCAF with inulin (KP T2 = 41.1 ± 3.59%) and was significantly different (p0.05) from the protein-energy-deficient rats fed Manggu MOCAF without inulin group (KEP M1= 25.7 ± 6.71%). This study concluded that inulin-enriched MOCAF-based diet could improve the calcium balance in undernourished rats.   AbstrakPenelitian ini bertujuan untuk mengetahui pengaruh pemberian diet berbasis MOCAF diperkaya inulin terhadap efektivitas penyerapan kalsium pada model tikus kurang gizi.

Multi-scale stormwater harvesting to enhance urban resilience to climate change impacts and natural disasters
Authors: Nguyen Thuy Thi , Bach Peter M. , Pahlow Markus
Published: June 2022

Stormwater harvesting systems are a viable option to adapt cities to cope with climate change and reduce pressure on water supply services. This is particularly crucial in the event of natural disasters (e.g., earthquakes, floods), where large parts of cities may become disconnected from a secure water supply for prolonged time periods. We demonstrate how optimum location, density and storage size can be determined using UrbanBEATS, a spatial planning-support system for planning and design of sustainable Blue-Green Infrastructure strategies. We investigate the Ōtākaro/Avon River catchment, Christchurch, New Zealand for the time periods 2011–2020, 2041–2050 and 2091–2100 (for the RCP 8.5 climate change scenario). For targets of 30% of potable water substitution and 70% storage volumetric reliability, we found that stormwater harvesting systems in all climate scenarios required a larger capacity compared to the baseline. Most storages achieved their set targets and were larger than the municipality's recommended 9 m3 for flood inundation, indicating that the identified storages would also reduce minor flooding while ensuring water savings. A shift in the spatial layout of modelled systems from highly distributed to more centralised, however, raises a potential conflict with disaster resilience where more local solutions would be preferable.

Published: June 2022

Water resources are not only the essential natural resources for the national economy and people's livelihood but also are the strategic economic resources for the safe production of energy and food. However, the shortage of water resources caused by extreme climate is a great challenge to energy enterprises and food producers. According to the game theory and the theory of economic development stage, this paper constructs an evolutionary game model for local governments, energy enterprises, and food producers. Further, it analyzes the evolutionary stability strategies of the game players at different development stages through simulations. The results indicate that: (1) the game players have different strategies of evolutionary stability at different development stages, while local governments adopting water-saving policies will promote the water-saving behavior of energy enterprises and food producers; (2) the choice of water-saving behavior of energy enterprises and food producers mainly depends on the water-saving costs; (3) the guidance of the government and the management of water-saving cost make the large water consumers realize the transformation from the ‘competition of water-consuming’ to the ‘cooperation of water-saving.’ According to the above analysis, many political recommendations are further put forward.

Published: June 2022

Due to the physical processes of floods, the use of data-driven machine learning (ML) models is a cost-efficient approach to flood modeling. The innovation of the current study revolves around the development of tree-based ML models, including Rotation Forest (ROF), Alternating Decision Tree (ADTree), and Random Forest (RF) via binary particle swarm optimization (BPSO), to estimate flood susceptibility in the Maneh and Samalqan watershed, Iran. Therefore, to implement the models, 370 flood-prone locations in the case study were identified (2016–2019). In addition, 20 hydrogeological, topographical, geological, and environmental criteria affecting flood occurrence in the study area were extracted to predict flood susceptibility. The area under the curve (AUC) and a variety of other statistical indicators were used to evaluate the performances of the models. The results showed that the RF-BPSO (AUC=0.935) has the highest accuracy compared to ROF-BPSO (AUC=0.904), and ADTree-BPSO (AUC=0.923). In addition, the findings illustrated that the chance of flooding in the center of the area in question is greater than in other points due to lower elevation, lower slope, and proximity to rivers. Therefore, the ensemble framework proposed here can also be used to predict flood susceptibility maps in other regions with similar geo-environmental characteristics for flood management and prevention.
Specifying optimum water resources based on cost-benefit relationship for settlements by artificial immune systems: Case study of Rutba City, Iraq
Authors: Eryiğit Miraç , Sulaiman Sadeq Oleiwi
Published: June 2022

The present study aims to specify optimum water resources depending on a cost-benefit relationship for residential areas by heuristic optimization. For this purpose, a case study of Rutba City in Iraq was applied. It is planned that water demand of the city is supplied by four different pumped pipelines (Pipelines 1–4). An optimum water supply among these pipelines was determined by considering their daily incomes (water charge per m3) and expenses (electricity price of pump stations), and daily demand for the city. In order to solve this optimization problem, a heuristic optimization model using a modified clonal selection algorithm (Clonalg), a class of artificial immune aystems was improved. The algorithm was coded in Matlab programming language, and it was run ten times to test its stability. Two objective functions of total daily income and expense were simultaneously used to maximize total daily net income under the constraints of the required daily water demand of the city and pump discharge capacities. Another constraint was that total net income for ten years should finance the initial cost of the unconstructed pipeline 4. The results showed that the optimization model using the modified Clonalg is useful and feasible for determining optimum water supply in terms of the cost-benefit relationship.
Evaluation of corrosion and scaling potentials of oilfield waters in an offshore producing facility, Niger Delta
Authors: Bolaji T. A. , Olumayede E. G. , Ojo A. M.
Published: June 2022

In this study, water samples from Miocene reservoirs, offshore Niger Delta, and seawater samples used for water injection were investigated in an attempt to examine the chemistry, evaluate the corrosion behaviour of steel, iron, and aluminium in different aqua media, and evaluate the scaling potentials of the oilfield produced waters (OFPW). Chemical analyses of the waters were determined; corrosion rate measurements were carried out by the weight loss method at room temperature while corrosion kinetics was carried out using conventional methods. Langelier saturation index (LSI), Ryznar stability index (RSI), Larson–Skold index (L–S), Puckorius scaling index (PSI), and aggressiveness index (AI) were evaluated for assessing the corrosiveness and scaling potential of the formation waters, using water quality data. The magnitude of corrosion of these metals was studied for an exposure period of 42 days. Chemical analysis revealed that the waters are slightly alkaline and generally classified as hard, saline water of the Na-Cl type based on its total dissolved solids (TDS). Produced water pH values range from 7.32 to 8.38. Results showed the likelihood of some of the water to form mild to severe scales based on the corrosivity indices, while the seawater samples are classified as ‘non-aggressive’ and ‘aggressive’. Steel has the highest corrosion rate with a value of 3.84 × 10−3 mg cm−2 h−1 compared to aluminium with the lowest rate of 0.37 × 10−3 mg cm−2 h−1. In most cases, the rate of corrosion of the metals followed the first-order rate constant in some of the samples, and the second-order in others within the first seven days. It was observed that the rate of corrosion follows this order: steel > iron > aluminium. The potential heavy and intolerable corrosion associated with the use of these seawater samples as injection waters is a potential risk that must be handled by adequate treatment.

Published: June 2022

The existence of a work from home policy does not seem to have a substantial impact on construction workers. Cases of work accidents on infrastructure projects during the Covid-19 pandemic experienced a significant increase. As reported by BPJamsostek data that the number of work accident insurance claims in the first semester (January-June) 2020 reached 108,573 cases. An increase of 128% over the same period in the previous year.  One of the steps from the construction side to minimize the occurrence of work accidents is by marking dangerous locations or limiting them with a yellow line. The supervision is carried out by the Occupational Health and Safety division which supervises every worker by using hearing and sight senses. However, this supervision is deemed less effective and efficient considering the number of work accidents that continue to increase over time. Therefore, a worker location monitoring system based on An indoor positioning system called Portable Construction Maps (PCM) Using Location Fingerprint Positioning Algorithm for Construction Worker Safety was developed. The development of this system uses the algorithm Location Fingerprint as a method for estimating the location of workers in a construction building. Each worker will bring a device called the Worker Tag, in which there is a microcontroller (Espressif 32) with WiFi and Bluetooth module, which is used to capture wifi and bluetooth signals and calculate the Received signal strength indication(RSSI) which will be sent to the server to be processed using the location fingerprint algorithm. In addition, in the worker tag there is also a Passive Buzzer that is used to alert workers if they enter a dangerous area.

Authors: Silva Thyago Ferreira da , Nascimento João Carlos Hipólito Bernardes do , Castro Maurício Mendes Boavista de
Published: June 2022

This article sought to identify the current panorama of the study of Quality Of Work Life (QWL) applied to telework in Public Organizations in Brazil. In methodological terms, it is an integrative literature review based on publications from the data platforms: CAPES, SPELL, SciELO and ENAP, delimited by the time frame from 2010 to 2021. By applying search descriptors and parameters for acceptance and rejection, 23 articles composed the corpus and supported the analyses. From the review it was found that, although there are still few researches in the area, a majority of teleworkers positively evaluate the QWL aspects in the telework modality, within the scope of public administration. The flexibility of the workday, the reduction of displacements and the reduction of costs, among other factors were cited as advantages. Despite this, issues such as the weakening of the bond with the company and co-workers and technical adaptation difficulties appear as compromising the QWL. The results achieved have the potential to support future research that addresses the quality of life of teleworkers within the scope of public administration. In addition, the present research can allow the reflection of governments and public managers on the benefits and challenges pointed out by the findings of the study.
