Typical Properties of Beverages with Different Ethanol Content: A Comparative Analysis
Authors: Lutkov Igor , Yermolin Dmitry 
Published: June 2023

Non-alcoholic beer and wine are in great demand. Some of them contain carbon dioxide. Dealcoholization makes it possible to obtain high-quality drinks, but changes in flavor and taste are unavoidable. This article introduces a comparative analysis of the typical properties of beer and sparkling wine with different levels of alcohol.
The research featured industrial samples of beer and sparkling wine with different volume fractions of ethyl alcohol. The comparative analysis relied on standard research methods and included sensory evaluation, acidity, sparkling properties in terms of carbon dioxide desorption rate, carbon dioxide content, foamy properties, viscosity, phenolic substances, beer proteins, and optical characteristics.
Alcoholic beer had a better taste and possessed a typical beer flavor. The flavor and taste profile of sparkling wines depended on the raw material. The sparkling coefficient of non-alcoholic beer was 1.2–7.5% higher than that of alcoholic beer because drinks with less ethanol have better carbon dioxide solubility. For alcoholic sparkling wine, the sparkling coefficient was higher by 19.7% than for its non-alcoholic analogue due to bound forms of carbon dioxide. The foaming properties of alcoholic drinks were better than those of the non-alcoholic samples due to the higher protein content. The yellowness and optical density of drinks at a wavelength of 350 nm depended on the amount of phenolic substances. The color index of beer depended on the content of melanoidins.
The modern dealcoholization technologies make it possible to produce non-alcoholic beverages with the same sensory properties as their alcoholic prototypes. However, these technologies can be improved in terms of bound carbon dioxide, proteins, phenolic substances, and flavor.

Abstract

Algeria is currently experiencing a real water shortage and leaks in the distribution networks, which affect the water supply. To reduce losses, the authorities have adopted a rehabilitation policy that requires resources that are not necessarily available. In this context, the aim of this study is to develop a decision support methodology for managers to enable them to plan urgent rehabilitation and to evaluate the benefits generated. The methodology consists of two phases: the diagnostic phase to identify a set of criteria, taking into account national specificities, and the planning phase, including the choice of Fuzzy-AHP for weighting and PROMETHEE II for ranking. An application is carried out on the Fouka network in Bejaia city (Algeria), consisting of 204 pipes. The application enabled the 204 pipes to be ranked in order of urgency and the benefits generated to be assessed in terms of environmental, economic, social, and technical parameters. The recovered water is significant in the first 60% of rehabilitated pipes. Investment costs are recovered within 3 years of the network being fully rehabilitated. The average reduction in network age is 5 years for every 10% of pipes rehabilitated. Complaints will be 0 after 70% of the pipes are rehabilitated.

Published: June 2023

Aim:
We aimed to examine all-cause mortality risk in relation to the extent of non-obstructive coronary artery disease (CAD) by coronary computed tomography angiography (CTA) in Chinese middle-aged and older patients in a multicenter study with nine-year follow-up.

Methods:
This was a retrospective, observational, multicentre study. The study population consisted of 3,240 consecutive middle-aged and older patients (age ≥ 40 years) with suspected CAD who underwent coronary CTA between June 2011 and December 2013 at three hospitals in Wuhan, China. Patients were grouped according to CAD extent for the final analysis: no CAD, 1-vessel non-obstructive CAD, 2-vessels non-obstructive CAD, and 3-vessels non-obstructive CAD. The primary endpoint was all-cause mortality. Kaplan-Meier method and Cox proportional hazards regression models were used for analysis.

Results:
A total of 2,522 patients were included in the present analysis. Of these, 188 (7.5%) deaths occurred during the median 9.0 years (interquartile range 8.6–9.4) of study follow-up. The annualized all-cause mortality rate was 0.54 (95% CI: 0.44–0.68), 0.91 (95% CI: 0.68–1.21), 1.44 (95% CI: 1.01–1.93), and 2.00 (95% CI: 1.46–2.69) for the no CAD, 1-vessel non-obstructive CAD, 2-vessels non-obstructive CAD, and 3-vessels non-obstructive CAD group, respectively. Kaplan–Meier survival curves showed a significant increase in the cumulative events associated with the extent of non-obstructive CAD (P < 0.001). In multivariate Cox regression, after adjustment for age and sex, the presence of 3-vessels non-obstructive CAD was a significant predictor of all-cause mortality (HR 1.60, 95% CI: 1.04–2.45, P = 0.032).

Conclusion:
In this cohort of Chinese middle-aged and older patients undergoing coronary CTA, the presence and extent of non-obstructive CAD, compared to no CAD, were associated with a significantly greater nine-year risk of all-cause mortality. The present findings suggest the clinical importance of the stage of non-obstructive CAD and warrant investigation of the optimal risk stratification to improve outcomes among these patients.
Sex-disaggregated Analysis of Risk Factors of COVID-19 Mortality Rates in India
Authors: Kini Anush V. , P.B. Harish , Anand Monica , Ranjan Uma 
Published: June 2023

Background:
COVID-19 mortality rates vary widely across regions and sex/gender. Understanding the reasons behind such variation could help in developing suitable management strategies.

Methods:
This paper presents a comprehensive analysis of incidence and mortality rates on 2,331,363 cases and 46,239 deaths over a cumulative period of approximately 6.5 months from February to August 2020 across 411 districts of India in the age group 15-49. Together with health data from government surveys, we identify risk and protective factors across regions, socio-economic status, literacy, and sex. To obtain common indicators, we apply both machine learning techniques and statistical tests on different health factors. We also identify positive and negative correlates at multiple population scales by dividing the cohort into sub-cohorts formed from two Indian states that were further segregated by sex.

Results:
We show that males and females differ in their risk factors for mortality. While obesity (lasso regression coefficient: KA=0.5083, TN=0.318) is the highest risk factor for males, anemia (KA=0.3048, TN=0.046) is the highest risk factor for females. Further, anemia (KA=-0.0958, TN=-0.2104) is a protective factor for males, while obesity (KA=-0.0223, TN=-0.3081) is a protective factor for females.

Conclusion:
Districts with a high prevalence of obesity pose a significantly greater risk of severe COVID-19 outcomes in males. On the other hand, in females, the prevalence of anemia in districts is notably associated with a higher risk of severe COVID-19 outcomes. It is important to consider sex-wise heterogeneity in health factors for better management of health resources.

Open Science Hardware for Realising Globally Equitable Knowledge Production
Authors: Hsing Pen-Yuan , Johns Brianna 
Published: June 2023

Physical hardware underpins research in many disciplines. From computing devices, scientific instrumentation, and biological reagents, to remote sensing satellites, researchers rely on hardware to explore and understand the world. However, research equipment is typically based on closed source (i.e. proprietary) hardware, whose designs are legally restricted, preventing others from studying, building, or modifying them. These restrictions cause several problems such as: lack of reproducibility; duplication of effort; forced obsolescence; and higher costs.
Crucially, the inefficiencies of closed source hardware reinforce global inequities. This is because the design and manufacturing of research equipment is often monopolised by producers in the Global North. Restricted access to hardware designs mean that only authorised dealers and technicians are allowed to sell or maintain equipment. These services are often unavailable to, or prohibitively expensive for, researchers belonging to historically marginalised communities outside of the Global North.
Building on the success of open source software, open source hardware is defined as any physical artefact whose “design is made publicly available with explicit, legally binding freedoms for anyone to study, modify, distribute, make, and sell the design or hardware based on that design”. Open science hardware is an emerging field of practice which studies and applies the principles of open source hardware to research contexts. In 2021, it was formally recognised as a key component in the UNESCO Recommendation on Open Science. Open science hardware provides many benefits compared to its proprietary counterparts. This can include cost savings of up to 87% (Pearce, 2020) and proportional to how often it is replicated; quicker iteration of designs; and adaptation to local needs in underserved communities.
Since the 2010s, open science hardware has been developed and used in diverse domains from environmental monitoring, and lab automation, to microscopy. In addition to academics, open science hardware is commonly built by citizen science communities and adapted for different purposes. Other practitioners of open science hardware include educators, social innovators, or artists.
In this talk, we provide an overview of open science hardware and the problems it solves. We also provide successful examples of open science hardware projects that serve to not only do good science, but also address global inequities. The talk also presents the Gathering for Open Science Hardware, an international network working towards the adoption of open source hardware across research lifecycle.

Wave attenuation by sea ice in the Arctic marginal ice zone observed by spaceborne SAR
Authors: Huang Bingqing , Li Xiaoming 
Published: June 2023

Attenuation of ocean waves by ice is a crucial process of the
interaction between waves and sea ice in marginal ice zone (MIZ), while
such interaction can contribute to the retreating of sea ice in the
Arctic. Based on the retrieved two-dimensional ocean wave spectra by
spaceborne SAR, we investigated the attenuation of ocean waves in the
MIZ in Svalbard and Greenland. The results show that the energy
attenuation rate ranges from 0.126×10-4/m to
0.618×10-4/m . Quantitative analysis suggests that the
attenuation rate is significantly related to wave height and peak wave
period of coming waves. It is further found that the waves decay faster
in the area with ice thickness exceeding 0.5 m. We compared the derived
wave attenuation rates in the present study with those in previous
studies based on in situ measurements, which reveals that waves are
becoming less attenuated by sea ice in the Arctic in recent decades.

Published: June 2023

Background: The prevalence of cardiovascular events and the risk of mortality are higher among patients with Metabolic syndrome (MetS), and the risk factors include central obesity, increased blood pressure, increased fasting blood glucose (FBG) levels and abnormal blood lipids. Early diagnosis of MetS and timely intervention can prevent unnecessary complications related to its progression and help reduce the risk of Cardiovascular disorders (CVD).
Purpose: The purpose of this EHR-based real-world study was to identify the relationship between Triglyceride/High-density lipoprotein cholesterol (TG/HDL-C) ratio and metabolic syndrome.
Methods: Participants in the trial must have had type 2 diabetes mellitus for at least six months and must be presenting for routine treatment in one of 14 centres around the nation. Data on medical history, diabetes complications, medications, and laboratory values were gathered using an EMR (MEDEVA) integrated research proforma, and the study period was for six months (March-August 2022). Clinical and statistical professionals at MEDEVA combined anonymized data and conducted analyses using Python 3.6 (pandas, scikit-learn, SciPy for exploratory data analysis, and Matplotlib for exploratory visualisation), SPSS version 26 (statistical analysis).
Results: Of the 372 patients with Type 2 Diabetes Mellitus, 278 had Metabolic Syndrome (MetS), and 94 did not have MetS. The TG/HDL ratio was significantly higher for the group with MetS (5.1) than the group without MetS (2.7). As a next step, to avoid potential confounding, the sample was adjusted for BMI and age, i.e., covariate matching was done. The TG/HDL ratio continued to be higher for the group with MetS (5.4) than the group without MetS (2.7).
Conclusion: We discovered a strong link between metabolic syndrome and the TG/HDL-C ratio. A high TG/HDL ratio indicates an increased risk of developing metabolic syndrome.

Published: June 2023

Background and Aim: Type 2 diabetes (T2D) remission is widely reported across the world. However, there are no large-scale cohort studies that report the effectiveness of lifestyle intervention on T2D remission, especially in Indian population. The study aimed to evaluate the effectiveness of a one-year lifestyle modification program-Holistic Transformation Program (HTP) on T2D remission in Indian population.
Materials and methods: Patients with diagnosed T2D (&gt;18 years of age) were recruited in a one-year intensive lifestyle modification program at the Freedom from Diabetes Clinic, Pune (India) between April and December 2021. The intervention included a customized vegan diet, exercises, stress management support, and medical management. Anthropometric and biochemical parameters were assessed with scheduled consults every 3 months. Remission was defined as HbA1c&lt;48 mmol/mol for a minimum of 3 months without the use of antidiabetic medication.
Results: The mean age and duration of diabetes were 52.0±10.6 years and 10.3±7.9 years, respectively (n=2764). Post-intervention, median weight, and HbA1c decreased significantly (weight-71 kgs to 67 kgs, p&lt;0.01; HbA1c-7.5% to 6.6%) (p&lt;0.05). Remission was seen in 837 (30.3%) patients. Significantly higher remission was seen in those with &gt;15 kg weight loss and with diabetes duration of &lt;10 years (p&lt;0.05). Remission was highest in those who never started medication (with HbA1c&gt;48 mmol/mol at baseline) (79%) followed by those only on oral hypoglycemic agents (31.7%). Improvement in HbA1c and weight loss were similar between patients on external insulin and/or OHA (p&gt;0.1) indicating efficacy of the intervention irrespective of the medicine status at baseline.
Conclusion: Our findings suggest that customized lifestyle intervention is beneficial in achieving T2D remission in Indian population. A one-year post-intervention follow-up is underway to understand the long-term effects of the intervention.
