Geochemical, Biological, and Clumped Isotopologue Evidence for Substantial Microbial Methane Production Under Carbon Limitation in Serpentinites of the Samail Ophiolite, Oman

In hyperalkaline ( pH>10 ) fluids that have participated in low‐temperature (<150 °C ) serpentinization reactions, the dominant form of C is often methane ( CH4 ), but the origin of this CH4 is uncertain. To assess CH4 origin in serpentinite aquifers within the Samail Ophiolite, Oman, we determined fluid chemical compositions, analyzed taxonomic profiles of fluid‐hosted microbial communities, and measured isotopic compositions of hydrocarbon gases. We found that 16S rRNA gene sequences affiliated with methanogens were widespread in the aquifer. We measured clumped isotopologue ( CH313 D and CH212D2 ) relative abundances less than equilibrium, consistent with substantial microbial CH4 production. Furthermore, we observed an inverse relationship between dissolved inorganic C concentrations and δ13CCH4 across fluids bearing microbiological evidence of methanogenic activity, suggesting that the apparent C isotope effect of microbial methanogenesis is modulated by C availability. An additional source of CH4 is evidenced by the presence of CH4 ‐bearing fluid inclusions in the Samail Ophiolite and our measurement of high δ13C values of ethane and propane, which are similar to those reported in studies of CH4 ‐rich inclusions in rocks from the oceanic lithosphere. In addition, we observed 16S rRNA gene sequences affiliated with aerobic methanotrophs and, in lower abundance, anaerobic methanotrophs, indicating that microbial consumption of CH4 in the ophiolite may further enrich CH4 in 13C. We conclude that substantial microbial CH4 is produced under varying degrees of C limitation and mixes with abiotic CH4 released from fluid inclusions. This study lends insight into the functioning of microbial ecosystems supported by water/rock reactions.
Brakial Pleksus Bloğunun Pletismografik Variabilite İndeksi ve Perfüzyon İndeksi ile Değerlendirilmesi

Background: Conventional methods for evaluation of block success are time consuming and need patient cooperation. The aim of this study was to evaluate whether the Perfusion Index and Plethysmographic Variability Index can be used to predict brachial nevre block success. Materials and Methods: Thirty - four patients, aged 18 - 65 years, who were transferred to elective or emergency surgery were included. Brachial plexus block was applied. Those with cardiac disease, chronic obstructive pulmonary disease and asthma were excluded from the study. Bedside, non - invasive, serial plethysmographic variability index (PVI) and perfusion index (PI) measurements of the patients were made using the Radical - 97 Pulse Oximeter device from the fourth finger tip of the blocked hand. Results: When the PVI values measured from the blocked arm were compared; The difference between 0 and 5 minutes, 5th and 10th minutes and 0 to 10 minutes was statistically significant. When PI values were compared as 0 and 5 minutes, 5 and 10 minutes, 0 and 10 minutes, the changes were statistically significant. ( p<0.05). Conclusion: In our study, it was seen that the changes in PI and PVI values were statistically significant. ( p<0.05) There was no statistically significant correlation between PVI and PI.
Caspian Sea: Environmental controls and trophic webs interactions

Gelatinous zooplankton (GZ) populations are sensitive to climate change such as environmental perturbations, and spatial changes in their abundance and biomass may be associated with degraded environmental and biota conditions. Big data time series of GZ abundances and biomass were used to analyze the annual population dynamics of gelatinous zooplankton as well as mesozooplankton in the southern Caspian Sea, Iran from 1996, 2001-2006, 2008-2013 to 2018-2019. The ctenophore, Mnemiopsis leidyi population control by environmental factors was primarily a result of decreasing the concentration of zooplankton resulted to lower reproduction as well as temperature which was highest in August-September and lowest in winter time. On the other hand, the maximum catch of Kilka on the whole coast of Iran was equivalent to 95,000 tons in the year of 1996, and after that it was severely reduced to 15,000 tons in the year 2003 and afterward. Key words: Gelatinous zooplankton, abundance and biomass, temperature, Caspian Sea.
A Review of methodologies for Fault Location Techniques in Distribution Power System

Since recent societies become more hooked into electricity, a higher level of power supply continuity is required from power systems. The expansion of those systems makes them liable to electrical faults and several failures are raised due to totally different causes, like the lightning strike, power system element failure caused by mechanical aging as well as human mistakes. These conditions impact the stability of the power as well as lead to costly maintenance and loss of output. This article examines the latest technologies and strategies to determine the location of faults in medium voltage distribution systems. The aim is to classify and assess different strategies in order to determine the best recommended models in practice or for further improvement. Several ways to locate failures in distribution networks have therefore been established. Because faults are unpredictable, quick fault location as well as isolating are necessary to reduce the impact of faults in distribution networks as well as removing the emergency condition from the entire system. This study also includes a comprehensive evaluation of several defect location methods depending on the algorithm employed, the input, the test system, the characteristics retrieved, and the degree of complexity. In order to gain further insight into the strengths and limitations of each method and also comparative analysis is carried out. Then the main problems of the fault location methods in distribution network are briefly expounded
Meta-analysis of associations between cooking oil fumes exposure and lung cancer risk

Lung cancer is one of the most common cancers and cooking oil fumes (COF) are considered as the potential dangerous contributing factors. This study, a meta-analysis was conducted to analyse the correlation between exposure to COF and risk of lung cancer. Literature from 1980 to 2020 were searched and 29 studies were selected for analysis. Results showed that population exposed to COF had significant differences in lung cancer prevalence (P < 0.05). The odds ratio (OR) values of different periods (before 2000, 2000–2010 and 2010–2020) were significantly different. Using ventilation equipment had the OR of 0.54. Liao cuisine, Fujian cuisine, Shanghai cuisine, Jingdong cuisine and Shaanxi cuisine had the ORs (95% confidence interval) of 1.91 (1.62, 2.25), 2.38 (1.80, 3.16), 1.56 (1.29, 1.89), 2.58 (1.63, 4.09) and 1.57 (1.16, 2.11), respectively. These results revealed that exposure to COF could increase the risk of lung cancer, but the risk was gradually reduced with the changes of the times and the use of ventilation equipment. Different cooking methods in different regions caused different risks of lung cancer. The risk of lung cancer caused by COF mainly produced by deep-frying, quick-frying, stir-frying and pan-frying is higher than in other methods.
Comparing Family-related Factors, Nutritional-behavioral Habits, and Lifestyle Between Obese and Non-obese Children

Background and Aim: Considering the importance of childhood obesity and easier correction of related factors in this age group, the present study aimed to investigate the role of some factors related to family, nutrition, and lifestyle on childhood obesity. Methods & Materials: This age-matched case-control study was performed on 150 obese and 150 healthy children, aged 2-15 years referring to Amir-Kabir Hospital in Arak City, Iran. Obesity was calculated based on Body Mass Index (BMI). Required information, including family factors, nutritional factors, and lifestyle characteristics were collected by a checklist. Ethical Considerations: This study was approved by the Ethics Committee of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1396.119). Results The results of Odds Ratio (OR) with 95% of Confidence Interval (CI) were in favor of father’s age of 25-35 and over 35 years (0.24), respectively, father’s overweight and obesity (3.87 and 3.57), mother’s overweight and obesity (3.81 and 5.5)7, more than three children per household (3.33), low and high consumption of fruits and vegetables (0.3 and 0.19), breakfast eating (0.43), dietary supplementation (2.68), consuming fast food (3.98), more than two hours of playing a computer game (3.5), chewing well (0.38), using food as a reward (1.89), as well as participating in food and table preparation (3.14). We found a dose-response association between children’s obesity and parents’ BMI, the number of children, and computer games. Conclusion: Obesity is associated with some factors related to the family, such as nutrition, computer games, and lifestyle characteristics. Due to various risk factors and adjustable safeguards, it is necessary to provide families and children with proper education to reduce obesity.
A Novel Approach based on Lifting Wavelet Transform for MIMO-OFDM Systems

In this article, two methods are proposed to further increase the advantages of MIMO-OFDM systems such as high access quality, high data rates and spectral efficiency. The first of these is the combination of the MIMO-OFDM system with the fast Walsh Hadamard transform (FWHT) due to its high accomplishment with the ability to spread the data versus the disturbing influences of the channel. The second is the combination of Lifting wavelet transform (LWT), due to its superior advantages such as good time-frequency localization properties, ICI and ISI suppression capabilities due to its orthonormal structure, unlike fast Fourier transform (FFT), with MIMO-OFDM scheme. Computer simulation studies are carried out to verify the accomplishment of the suggested methods over the bit error rate (BER) and peak to average power ratio (PAPR) benchmark. From the acquired outcomes, it is noticed that approximately 6 dB of SNR gain and approximately 2 dB of PAPR gain are achieved with the proposed method.
Nucleus Type-Specific DNA Methylomics Reveals Epigenetic “Memory” of Prior Adaptation in Skeletal Muscle

Abstract Using a mouse model of conditional and inducible in vivo fluorescent myonuclear labeling (HSA-GFP), sorting purification of nuclei, low-input reduced representation bisulfite sequencing (RRBS), and a translatable and reversible model of exercise (progressive weighted wheel running, PoWeR), we provide the first nucleus type-specific epigenetic information on skeletal muscle adaptation and detraining. Adult (>4 mo) HSA-GFP mice performed PoWeR for 8 wk then detrained for 12 wk; age-matched untrained mice were used to control for the long duration of the study. Myonuclei and interstitial nuclei from plantaris muscles were isolated for RRBS. Relative to untrained, PoWeR caused similar myonuclear CpG hypo- and hyper-methylation of promoter regions and substantial hypomethylation in interstitial nuclear promoters. Over-representation analysis of promoters revealed a larger number of hyper- versus hypo-methylated pathways in both nuclear populations after training and evidence for reciprocal regulation of methylation between nucleus types, with hypomethylation of promoter regions in Wnt signaling-related genes in myonuclei and hypermethylation in interstitial nuclei. After 12 wk of detraining, promoter CpGs in documented muscle remodeling-associated genes and pathways that were differentially methylated immediately after PoWeR were persistently differentially methylated in myonuclei, along with long-term promoter hypomethylation in interstitial nuclei. No enduring gene expression changes in muscle tissue were observed using RNA-sequencing. Upon 4 wk of retraining, mice that trained previously grew more at the whole muscle and fiber type-specific cellular level than training naïve mice, with no difference in myonuclear number. Muscle nuclei have a methylation epi-memory of prior training that may augment muscle adaptability to retraining.
Brand clarity of local and global brands in fast-moving consumer goods: an empirical study in a Middle East country

Purpose This paper aims to analyze different brand clarity levels (BCLs) of local, global and glocal types of brands in fast-moving consumer goods from the consumer's perspective. The study also intends to identify whether the consumer's previous experience with such brands may impact BCL. Design/methodology/approach Twenty-eight global and local brands were used to test the hypotheses by conducting a survey with 400 consumers in the emerging economy of Iran. The authors applied a quantitative technique of brand classification, previously proposed in the literature. After categorizing the brands as local, global or glocal, one-way ANOVA, Tukey post hoc and t-test analyses were performed to identify whether the different types of brands had different BCLs. Findings The results showed that brand clarity was significantly higher for local bands than for global or glocal brands and that it was higher for glocal bands than for global brands. Furthermore, the consumer's prior experience with a brand had no impact on BCL for different types of brands. Social implications For global brand managers, it is essential to know that local brands in Middle Eastern emerging markets may have more brand clarity than global brands. Therefore, if global brands intend to enter these markets, adopting a glocal positioning appears to be a helpful strategy. Besides, the results suggest that managers should analyze brand categorization from the consumer's perspective, i.e. from a subjective instead of an objective perspective. Originality/value This was the first study analyzing the BCL of local, global and glocal brands and identifying significant differences in their BCL.
Mitigating the impact of SARS-CoV-2 on residential facilities for persons with intellectual disability and/or autism spectrum disorder: two experiences from the Italian red zone

Purpose Persons with intellectual disability and/or low-functioning autism spectrum didorder are with high support need (ID/ASD-HSN) are among the people who are most vulnerable to the COVID-19 pandemic. The specific vulnerability and the protective factors for persons with ID/LF-ASD attending residential and rehabilitative facilities have however received little attention. This paper aims to describe how two facilities located in the Italian COVID-19 red zone faced the risks associated with the spread of the pandemic and the results they have achieved so far. Design/methodology/approach Interventions to contrast the spread of the pandemic and preserve clients’ health conditions have been systematically monitored and recorded since the very beginning of the pandemic. Findings 26/138 clients had to undergo clinical screening and laboratory tests for COVID-like symptomatology, but only one resulted affected by COVID-19 and survived. Considering that Lombardy had 89,595 cases and 16,262 deaths (January–May 2020), one COVID-19 case/138 clients is a good result. Temporarily limiting physical contacts with friends/family in favor of reducing the burden of risk and adopting a system of prevention/safety strategies directed for persons with ID/LF-ASD attending and their caregivers have been useful measures. Research limitations/implications Structured or semi-structured interviews (using professional caregivers as informant) to confirm behavioral and emotional changes in the clients could not be carried out because of lack of time and resources (which were captured by the management of the pandemic) and could be the next goal for our residential facilities to implement the management of epidemic acute phases in a research-oriented view. Originality/value This study is a service evaluation report about facing COVID-19 pandemic. Only few such studies are present in medical literature about ID/ASD.
Fusion cardiac resynchronization therapy in an left ventricular assist device patient from two devices and crossing leads: a case report

Abstract Background Cardiac implanted electronic devices (CIED) have significantly improved the survival and quality of life in heart failure patients. Although implantable cardioverter-defibrillators (ICD) and cardiac resynchronization therapy (CRT) have a major role in patients with moderate to severe heart failure symptoms, the role of these devices in patients with a left ventricular assist device (LVAD) is not yet well defined. The burden of CIED-related procedures in patients with an LVAD is high. The price of lead malfunctions and pocket complications requires creative approaches to tackle CIED-related issues in this patient population. Case summary Here, we describe the clinical course of a 67-year-old ventricular pacing dependent LVAD patient with an ICD indication based on recurrent monomorphic ventricular tachycardias and a CRT indication due to previous deterioration of (right-sided) heart failure in the absence of biventricular pacing. We were confronted with impending right ventricular lead failure and bilateral venous access problems due to chronic subclavian vein occlusion in a patient with a total of five transvenous leads, therapeutic anticoagulation, and pronounced thoracic collaterals. We sought for a creative solution to be able to deliver effective biventricular fusion pacing with the existing leads from two contralateral pulse generators resulting in biventricular fusion pacing. This provided the solution to deliver effective CRT. Discussion This case illustrates the complexity of care and CIED-related decision-making in pacing dependent LVAD patients, in particularly those with an ICD and CRT indication.
The grey zone between tactics and manipulation: The normalization of match-fixing in road cycling

Match-fixing has already been studied in various sport disciplines. However, despite some well-known incidents in road cycling, match-fixing has barely been investigated in this unique sport discipline. Drawing on Ashforth and Anand’s theoretical model of normalization of corruption in organizations and on the perceptions of 15 active Belgian road cyclists, this study examines road cyclists’ attitudes towards collaboration and match-fixing in their sport. As the culture of agreements can be seen as part and parcel of road cycling itself, this study also examines whether agreements between cyclists are embedded, perpetuated, and thus normalized in road cycling. Using semi-structured interviews, this qualitative study indicates that road cyclists have a different understanding of match-fixing. By demonstrating that (a) cooperation between competitors happens routinely, (b) cyclists use self-serving explanations to justify these collaborations, and (c) newcomers are induced to engage in and accept collaborations with their competitors, we also indicate how normalized behaviors contribute to a grey zone that can be labelled as match-fixing. To enhance the future credibility of road cycling towards both fans and sponsors, additional clarifying and awareness-raising policy measures should be implemented.

Improving the subdivision accuracy of photoelectric encoder using particle swarm optimization algorithm

The aim of this study is to improve the subdivision accuracy of a photoelectric encoder and reduce the effects of sinusoidal errors in signals on the measurement accuracy of the system. To this end, an optoelectronic chip that can receive grating moiré fringe signals was designed, along with an amplifier circuit with a hierarchical pipelined architecture. The photodetector array was matched with the code disk before processing the received signals. The sinusoidal errors in the signals were quantitatively analyzed. The results were used to develop a sinusoidal error-compensation method based on a particle swarm optimization (PSO) algorithm. A subdivisional error-compensation model was established to correct the errors in those signals. A rapid solution to the PSO algorithm was implemented on a field-programmable gate array, and a grating test platform was constructed for experimental verification. The peak-to-peak subdivision error of the encoder’s photoelectric signal decreased by approximately 60% from 2. 98ʺ to 1. 13ʺ. Therefore, the proposed scheme not only significantly improves the measurement accuracy of the photoelectric shaft angle encoder, but also contributes to its miniaturization.
