Residing without settling: Housing market and tactics of Syrian forced migrants in Turkey
Authors: Kurfalı Merve Akdemir , Özçürümez Saime 
Published: August 2023

AbstractHow do forced migrants from Syria cope with structural barriers to housing in urban centres in Turkey? More than 3.6 million Syrian refugees have lived in different cities in Turkey since the closing of the temporary accommodation centres in 2018. This study examines the agency of Syrians and their housing pathways in securing accommodation in a neoliberal housing market amidst increasing unwelcoming attitudes by the local population, no social housing, high dependence on rental housing prone to price hikes, and “temporary protection” legal status. Based on analysis of data from 34 semi‐structured interviews with forced migrant Syrians and 20 expert interviews in Gaziantep, a city close to the Turkey‐Syria border with a substantial Syrian population, the research identifies four tactics that characterise housing pathways of Syrian forced migrants: (1) acting through local community members, (2) working with a Syrian mediator, (3) settling down in Syrian‐only buildings or informal settlements, and (4) purchasing a house through circumventing the legal ban on property ownership. The study concludes by highlighting that while these tactics are necessary for meeting forced migrants’ immediate housing needs, they are far from sufficient in preventing exclusion in the Turkish housing market.
A simple method for rapid removal of the memory effect in cavity ring‐down spectroscopy water isotope measurements
Authors: Keinan Jonathan , Goldsmith Yonaton 
Published: August 2023

RationaleThe accuracy determined in the routine analysis of water isotopes (δ17O, δ18O, δ2H) using cavity ring‐down spectroscopy is greatly affected by the memory effect (ME), a sample‐to‐sample carryover that biases measurements. This study aims to develop a simple method that rapidly removes the ME.MethodsWe developed a method, designed for the Picarro L2140‐i, that removes the ME by injecting small amounts of water with an extreme isotopic value (“kick”) in the opposite direction of the ME. We conducted 11 experiments to identify the optimal kick for pairs of isotopically enriched and depleted samples. Once quantified, the optimal kick was used to create an ME‐free, unbiased calibration curve, which was verified using international and internal lab standards.ResultsOur kick method removes the ME very efficiently in half the time it takes for experiments without a kick. The optimal number of kick injections required to minimize stabilization time between standards of different compositions is three injections of δ2H ≈ −1000‰ water per a 100‰ difference between standards. Three runs of routine measurements using the kick method resulted in uncertainties of 0.03‰, 0.2‰, and 5 permeg for δ18O, δ2H, and 17O‐excess, respectively.ConclusionsThis study demonstrates a new method for rapidly removing the ME. Our kick protocol is a readily available, cheap, and efficient approach to reduce instrumental bias and improve measurement accuracy.

AbstractA 58‐year‐old woman with tetralogy of Fallot was referred to our hospital with a 2‐month history of hemoptysis and low‐grade fever. The sputum smear on admission showed positive results for acid‐fast bacilli, and comparative genomic analysis of the cultured sputum confirmed Mycobacteroides abscessus subsp. abscessus infection. Long‐term combination antimicrobial therapy gradually improved the patient's symptoms. Although non‐tuberculous mycobacteria infection is rarely observed in patients with cyanotic congenital heart disease, a worldwide increase in non‐tuberculous mycobacteria infections may increase the incidence of this rare combination.

Published: August 2023

AbstractTo improve the noise reduction and fire resistance of marine coating materials, some fire‐resistant polyurethane damping materials were prepared by varying the ratio of esterified branched polyols (EBP) and the 1,4 butanediol (1,4 BD), the content, and the particle size of the mica filler. The effects of branch chain, mica filler content, and particle size in polyurethane structure on the mechanical, dynamic mechanical properties, and fire resistance of polyurethane and its polymerization process were studied. The experimental results showed that the effective damping temperature range of polyurethane material widened from 42.1 °C to 76.6 °C, and then narrowed to 31.2 °C with the increase in EBP ratio. And the maximum loss factor (tanδmax) of these samples is 0.989. The increase of mica content and the decrease of mica particle size in polyurethane damping materials make the dynamic mechanical properties of polyurethane damping materials present a trend of first improving and then impairing. Moreover, the mechanical properties of polyurethane enhanced with the increase of EBP and weakened with the increase of mica mass fraction. This research is expected to advance the development of marine coatings and address noise reduction and fire protection challenges for marine materials.

AbstractDiabetic complications poses major threat to mankind which found to be dangerously fatal all over the world. It is thought vital to find new class of molecules to combat diabetic problems. Thus, in continuation of our efforts in identifying new class of α‐glucosidase and α‐amylase inhibitors, a novel series of hybrid molecules comprising of imidazo[1,2‐a]pyridine and pyrazoles, i. e. (3‐(Substituted phenyl)‐1H‐pyrazol‐4‐yl)methylene)‐2,7‐dimethyl‐1H‐imidazo[1,2‐a]pyridine‐3‐carbohydrazide derivatives (8 a–m) were designed through a acyl hydrazone bridge. The compound (Z)‐N′‐({3‐[4‐(2‐Fluorobenzyloxy)phenyl]‐1H‐pyrazol‐4‐yl}methylene)‐2,7‐dimethyl‐imidazo[1,2‐a]pyridine‐3‐carbohydrazide (8 m) emerged as potent inhibitor of α‐glucosidase and α‐amylase enzyme with IC50 5.00±0.10 μg/mL and 15±0.35 μg/mL respectively. The enzyme kinetics studies revealed reversible non‐competitive mode of inhibition of 8 m against both enzymes. In addition, these compounds were subjected to detailed in‐silico studies to understand their interaction with respective target proteins.

AbstractThe purpose of this study is to develop instant coarse cereal porridge to improve the convenience of coarse cereals by precooking. The effects of cooking time on the rehydration rate and gelatinization degree of coix seeds, red beans, lotus seeds, wheat kernels, and glutinous rice are investigated using the atmospheric pressure precooking process. Cooking time and quality variations of the coarse cereals are analyzed before and after precooking. The optimal cooking times for coix seeds, red beans, lotus seeds, wheat kernels, and glutinous rice under atmospheric pressure cooking are 110, 65, 40, 40, and 35 minutes (abbr. min), respectively. The rehydration rates are 171.5%, 190%, 170.67%, 224%, and 182.67%, respectively, and the gelatinization degrees are 90%, 74.54%, 80.1%, 92.85%, and 96.97%, respectively. The cooking times of pre‐cooked and pressed coix seeds, red beans, lotus seeds, wheat kernels, and glutinous rice are 10, 8, 12, 10, and 6 min, respectively. Compared to coarse cereals without precooking, the cooking time is reduced by 6.6, 6.5, 3, 4, and 2.3 times, respectively. Instant porridge prepared by combining precooked coarse cereals and dried fruits and vegetables can be consumed after soaking in boiling water for 20 min or boiling for 10 min.

AbstractBisphenol AF (BPAF), a BPA‐substitute, has been widely used in industrial compounds throughout the world. Several studies have shown that BPAF has endocrine interference and reproductive toxicity. However, the toxic effects of BPAF on pregnancy and placenta of goats are still unclear. Therefore, the objective of this study was to reveal the toxic effect of BPAF by using an in vitro culture model of caprine endometrial epithelial cells (EECs) and further attempted to alleviate the toxicity by curcumin pretreatment. The results showed that BPAF induces significant effects on EECs, including decreased cell viability and mitochondrial membrane potential (△ψm), elevating intracellular reactive oxygen species (ROS), promoting cell apoptosis through upregulating the expression of Bax, Cytochrome c, and downregulating the expression of Bcl‐2. Meanwhile, BPAF induced dysregulation of oxidative stress by increasing the levels of malondialdehyde (MDA) and glutathione peroxidase (GSH‐Px) but decreasing the activities of superoxide dismutase (SOD). However, curcumin pretreatment could significantly attenuate BPAF‐induced toxic effects in EECs. Further study revealed that BPAF treatment could activate mitogen‐activated protein kinase (MAPK) pathway and nuclear factor‐erythroid 2‐related factor 2 (Nrf2) expression, but curcumin pretreatment significantly inhibited the activation of MAPK signal pathway and Nrf2 expression induced by BPAF. Overall, this study indicated that curcumin could prevent BPAF‐induced EECs cytotoxicity, which provides a potential therapeutic strategy for female infertility associated with BPAF exposure.

AbstractPresent dependence on fossil sources for meeting energy demand globally is unsustainable as a result of non‐renewable and depleting supplies. Therefore, this study focuses on production and characterization of biodiesel by Chlorococcum littorale (Chlorococcum sp.) isolated from fish pond in Owode fish farm, Nigeria. Biomass concentration, lipid extraction and quantification were determined by filtration, solvent extraction and gravimetric methods. Extracted lipid was transesterified to diesel through process catalyzed by concentrated tetraoxosulphate (VI) acid. The constituents of fats in biodiesel produced were examined through chromatography of gas and spectroscopy of mass. Model prediction was used to assess physical and chemical parameters of biodiesel. The data gathered was subjected to statistical analysis. Chlorococcum sp. had biomass concentration (4.42 ± 0.02 g/L), Lipid content (67.75% and biodiesel yield (96.33%). Biodiesel had 48.3%, 29.20%, and 22.50% fatty acids that are saturated, monounsaturated and polyunsaturated, respectively. The biodiesel produced has the kinematic viscosity (2.74 mm2/s at 40°C); point of flash (245°C); point of cloud (7°C); point of pour (−2°C) and density (0.8760 g/cm3). Furthermore, the acidity level (0.44 mgKOH/g), value of saponification (186.49 mgKOH/g), value of peroxide (3.25 meq/kg), iodine content (38.27 mgI2/g) as well as the free fatty acid (1.34%), number of cetane (65.78), oxidative resistance (7.33 h), saturated factor of long chain (28.16°C), plugging point of cold filter (35.62°C) and high heating value (43.24°C) fell within required standard by international body. Thus, Chlorococcum sp. is ideal microalgae isolate for the biodiesel production. The biodiesel produced conform satisfactorily with the acceptable global standard.

ABSTRACTObjectiveFetoscopic laser photocoagulation (FLP) is a well‐established treatment for twin–twin transfusion syndrome (TTTS) between 16 and 26 weeks' gestation. High‐quality evidence and guidelines regarding the optimal clinical management of very early (prior to 16 weeks), early (between 16 and 18 weeks) and late (after 26 weeks) TTTS are lacking. The aim of this study was to construct a structured expert‐based clinical consensus for the management of early and late TTTS.MethodsA Delphi procedure was conducted among an international panel of experts. Participants were chosen based on their clinical expertise, affiliation and relevant publications. A four‐round Delphi survey was conducted using an online platform and responses were collected anonymously. In the first round, a core group of experts was asked to answer open‐ended questions regarding the indications, timing and modes of treatment for early and late TTTS. In the second and third rounds, participants were asked to grade each statement on a Likert scale (1, completely disagree; 5, completely agree) and to add any suggestions or modifications. At the end of each round, the median score for each statement was calculated. Statements with a median grade of 5 without suggestions for change were accepted as the consensus. Statements with a median grade of 3 or less were excluded from the Delphi process. Statements with a median grade of 4 were modified according to suggestions and reconsidered in the next round. In the last round, participants were asked to agree or disagree with the statements, and those with more than 70% agreement without suggestions for change were considered the consensus.ResultsA total of 122 experts met the inclusion criteria and were invited to participate, of whom 53 (43.4%) agreed to take part in the study. Of those, 75.5% completed all four rounds. A consensus on the optimal management of early and late TTTS was obtained. FLP can be offered as early as 15 weeks' gestation for selected cases, and can be considered up to 28 weeks. Between 16 and 18 weeks, management should be tailored according to Doppler findings.ConclusionsA consensus‐based treatment protocol for early and late TTTS was agreed upon by a panel of experts. This protocol should be modified at the discretion of the operator, according to their experience and the specific demands of each case. This should advance the quality of future studies, guide clinical practice and improve patient care. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.
Collaboration for source water protection in the United States: Community water systems engagement in nitrate pollution reduction
Authors: Rauh Eleanor , Hughes Sara 
Published: August 2023

AbstractContaminated source water for cities contributes to negative human health impacts and rising water treatment costs. Nutrient pollution is the primary source of surface water quality impairment in the United States and agriculture is the largest source of nutrient pollution (specifically nitrogen or nitrate) entering waterways. Solutions to source water contamination have historically centered on nutrient removal at the drinking water plant, which often requires additional investment. Pollution prevention through watershed management may be more cost‐effective in some contexts and has greater co‐benefits, and some drinking water managers and agricultural stakeholders have collaborated to create successful prevention programs. However, drinking water managers must balance several service requirements and regulatory standards, and may lack the resources or capacity needed to effectively engage in or initiate regional collaborations. This paper serves as an introduction to nutrient contamination of source waters and protection measures in the United States and provides a discussion of watershed‐scale collaboration, particularly the engagement of municipal drinking water managers.This article is categorized under:

Digesters as heat storage: Effects of the digester temperature on the process stability, sludge liquor quality, and the dewaterability
Authors: Steiniger Bettina , Hubert Christian , Schaum Christian 
Published: August 2023

AbstractVariation of the digester temperature during the year enables the operation of digesters as seasonal heat storage contributing to a holistic heat management at water resource recovery facilities. Full‐ and lab‐scale process data were conducted to examine the effect of the digester temperature on process stability, sludge liquor quality, and dewaterability. Both full‐ and lab‐scale digesters show a stable anaerobic degradation process with a hydraulic retention time of more than 20 days and organic load rates up to 2.2‐kg COD/(m3·day) at temperatures between 33 and 53°C. The concentrations of soluble COD and ammonium‐nitrogen in the sludge liquor digested at 53°C are 2.6 to 5.8 times and 1.3 times higher, respectively, than in the sludge liquor digested at 37°C. Dewatering tests show an enhancement of the dewaterability but a clear increase in the polymer demand at increased digester temperature.Practitioner Points
Digesters can operate as seasonal heat storage within mesophilic and thermophilic temperatures
Stable anaerobic degradation process for HRT above 20 days
Maintenance of process stability as well as quantity and quality of biogas
Increase of soluble COD in sludge liquor at higher temperatures
Better dewaterability but higher demand for polymers with increasing temperature
Recent developments in the use of centrifugal spinning and pressurized gyration for biomedical applications
Authors: Ahmed Jubair , Gultekinoglu Merve , Edirisinghe Mohan 
Published: August 2023

AbstractCentrifugal spinning is a technology used to generate small diameter fibers and has been extensively studied for its vast applications in biomedical engineering. Centrifugal spinning is known for its rapid production rate and has inspired the creation of other technologies which leverage the high‐speed rotation, namely Pressurized Gyration. Pressurized gyration incorporates a unique applied gas pressure which serves to provide additional control over the fiber production process. The resulting fibers are uniquely suitable for a range of healthcare‐related applications that are thoroughly discussed in this work, which involve scaffolds for tissue engineering, solid dispersions for drug delivery, antimicrobial meshes for filtration and bandage‐like fibrous coverings for wound healing. In this review, the notable recent developments in centrifugal spinning and pressurized gyration are presented and how these technologies are being used to further the range of uses of biomaterials engineering, for example the development of core‐sheath fabrication techniques for multi‐layered fibers and the combination with electrospinning to produce advanced fiber mats. The enormous potential of these technologies and their future advancements highlights how important they are in the biomedical discipline.This article is categorized under:

Global constraints on non-standard neutrino interactions with quarks and electrons
Authors: Coloma Pilar , Gonzalez-Garcia M. C. , Maltoni Michele , Pinheiro João Paulo , Urrea Salvador 
Published: August 2023

Abstract
We derive new constraints on effective four-fermion neutrino non-standard interactions with both quarks and electrons. This is done through the global analysis of neutrino oscillation data and measurements of coherent elastic neutrino-nucleus scattering (CEνNS) obtained with different nuclei. In doing so, we include not only the effects of new physics on neutrino propagation but also on the detection cross section in neutrino experiments which are sensitive to the new physics. We consider both vector and axial-vector neutral-current neutrino interactions and, for each case, we include simultaneously all allowed effective operators in flavour space. To this end, we use the most general parametrization for their Wilson coefficients under the assumption that their neutrino flavour structure is independent of the charged fermion participating in the interaction. The status of the LMA-D solution is assessed for the first time in the case of new interactions taking place simultaneously with up quarks, down quarks, and electrons. One of the main results of our work are the presently allowed regions for the effective combinations of non-standard neutrino couplings, relevant for long-baseline and atmospheric neutrino oscillation experiments.
