Abstract
Poultry processing industry produces large quantities of by products (skin, bone, and feather) that contain significant amounts of protein. The source of gelatine is of great concern for some societies including Muslims, Hindus, and Jews as gelatine is mostly obtained from porcine sources. In the present study, gelatine was obtained from chicken skin and some quality and functional features were evaluated in comparison with commercial gelatines from porcine, bovine, and piscine sources. Chicken skin gelatine formed stable foams by a foaming stability of 83.3% as well as high emulsion activity of 72.8 m2 g−1 compared to commercial gelatines. On the other hand, gel strength and viscosity of chicken skin gelatine were 307 g and 2.5 cP, respectively, and significantly lower than that of commercial gelatines due to high content of impurities. The results concluded that chicken skin may be used in gelatine manufacturing upon efficient removal of fat, which was the most abundant component in the dry matter of chicken skin.
A fast method to seek the mean and variance of the summation of lognormal variables
Authors: Torres Hurtado Juan Guillermo , Bustamante Roberto , Caicedo Carlos E. 
Published: May 2022

The sum of lognormal variables has been a topic of interest in several fields of research such as engineering, biology and finance, among others. For example, in the field of telecommunications, the aggregate interference of radio frequency signals is modeled as a sum of lognormal variables. To date, there is no closed expression for the probability distribution function (PDF) of this sum. Several authors have proposed approximations for this PDF, with which they calculate the mean and variance. However, each method has limitations in its range of parameters for mean, variance and number of random variables to be added. In other cases, long approximations as power series are used, which makes the analytical treatment impractical and reduces the computational performance of numerical operations. This paper shows an alternative method for calculating the mean and variance of the sum of lognormal random variables from a computational performance approach. Our method has been evaluated extensively by Monte Carlo simulations. As a result, this method is computationally efficient and yields a low approximation error computation for a wide range of mean values, variances and number of random variables.

Background. Oncoplastic breast resections with perforator flaps are relatively common now; however, many studies demonstrate contradictory results, especially in terms of long-term outcomes.Objective: to assess short-term and long-term outcomes of oncoplastic breast resection with defect repair using perforator flaps.Materials and methods. This study included 62 breast cancer patients who underwent oncoplastic breast resection with defect repair using local perforator flaps, including lateral intercostal artery perforator (LICAP) flaps (40.3 %), lateral thoracic artery perforator (LTAP) (19.4 %), anterior intercostal artery perforator (AICAP) (27.4 %), and medial intercostal artery perforator (MICAP) (12.9 %) flaps. The assessment of oncological, functional, and aesthetic outcomes was performed in patients who were followed-up for at least a year (n = 57). Mean follow-up time was 26.5 months (range: 14–38 months).Results. The following complications were registered among the patients studied: seroma in the area of excised primary tumor (8.1 %), insufficient blood supply of the flap that caused focal lipofibrosis/liponecrosis (3.2 %), positive resection margin (3.2 %), low position of the submammary fold (11.3 %), locoregional recurrence (0 %), generalized process (3.5 %). All women evaluated their functional and aesthetic result as good or excellent. According to BCCT.core 3.0, 91.3 % of patients achieved good and excellent results.
An approach to the assessment of carbon reservesin KHMAO-Yugra using carbon maps
Authors: Bredihin Arsenty I. 
Published: May 2022

Khanty-Mansi Autonomous Okrug-Yugra has a large area of forest territories. And forest vegetation, like any vegetation, naturally dies sooner or later, as a result of which carbon dioxide is released into the atmosphere from organic matter. This fact leads to an increase in the greenhouse effect and an increase in global warming.
In order to prevent an increase in global temperature, it is necessary to estimate the carbon stock in the form of the amount of plant biomass, since more than 90% of the territory of the Khanty-Mansi Autonomous Okrug-Yugra (KhMAO-Yugra) is covered with forests.
One of the ways to assess plant biomass is to create so-called carbon maps using remote sensing of the Earth (remote sensing) and machine learning methods.
This paper provides an overview of existing solutions in the field of remote sensing and machine learning aimed at creating carbon maps. Based on this review, a research program has been proposed that will allow us to develop an approach that allows us to obtain a digital carbon map of the KhMAO with a given accuracy.

Authors: Gilmanov Sergey A. , Zelenaya Alina V. 
Published: May 2022

The subject of the study is the influence of writing a reflexive essay about a listened piece of music on the development of a person's creative potential. The purpose is a theoretical substantiation of the possibility of developing the creative potential of a person when writing reflexive essays and empirical confirmation of the proposed approach based on data from a pilot study conducted at the Children's art school in Khanty-Mansiysk (n=22). The theoretical methods of research were analysis, generalization, systematization. Empirical methods: experiment, testing, qualitative analysis of the texts of the essays of the investigated.
The authors conduct a brief analysis of methods for determining the level of creative potential and justify the possibility of using the survey method. The conditions that must be observed when selecting works and writing essays are described. Arguments are given in favor of the fact that writing an essay is not an interpretation of a musical work, and listening to the work itself is not part of psychotherapeutic methods. The results of the pilot study are presented, which with a certain probability indicate that the writing of the essay had an impact on the development of the creative potential of the person.
Thermal Modification of the Northwest Indian Shield: As Evidenced by Integrated Geopotential Modelling

Published: May 2022

Abstract
The architecture of the continental lithospheric mantle is vital for understanding the wide-ranging processes that govern the creation of Earth’s continents. The present investigation delineates the crustal and lithospheric boundaries underneath northwest India, which provides essential constraints as an imprint of tectonomagmatic events under the distinct tectonic setting. This study integrates three data sets (gravity, geoid, and topography data) and thermal parameters in a three-dimensional inversion algorithm to northwest India. Inversion results are constrained by available passive seismic crustal thickness, which we are using as a priori information. Our modelling results show crust down to a depth of 33 to 39 km in the Saurashtra and Kachchh region, which increases gradually to about 40 km beneath the Jaisalmer region. The deepest Moho at about 42-45 km is found under the Aravalli-Delhi fold belt and Indo-Gangetic plain. A comparable crustal thickness of 41-44 km is observed beneath the Bundelkhand craton. The mean crustal density varies laterally between 2850 and 2890 kg/m-3 in the study area. The lithosphere-asthenosphere boundary (LAB) is 115-145 km deep under Saurashtra and Kachchh regions, which remains comparable under the Barmer-Pokharan region (130-160 km). A moderate LAB depth under the Aravalli-Delhi fold belt (140-180 km) and relatively deeper under the Bundelkhand craton (175 to 185 km) reaches over 200 km below the Indo-Gangetic plain. The thinned lithosphere beneath the Kachchh, Saurashtra, and Barmer-Pokhran regions, crisscrossed by two different rift systems, together with the dominance of the volcanic centres of two major magmatic episodes, and the possible presence of a low-velocity zone in the subcrustal upper mantle region suggest a genetic link between the evolution and the multistage thermal modification of the mantle lithosphere of this region.

Published: May 2022

Abstract
Background
Hepatitis B virus (HBV) infection carries a risk of liver cancer and extrahepatic malignancy. However, the incidence trend and clinical course of malignant lymphoma (ML) in HBV patients are not well known.
Methods
Data about ML newly diagnosed in chronic hepatitis B (CHB) patients from 2003 to 2016 were collected from National Health Insurance Service claims.
Results
A total of 13,942 CHB patients were newly diagnosed with ML from 2003 to 2016. The number of patients increased 3.8 times, from 442 in 2003 to 1,711 in 2016. The 2-year survival rate of all patients was 76.8%, and the 5-year survival rate was 69.8%. The survival rate of patients taking antivirals due to high viral activity before their diagnosis with ML was significantly lower than that of patients with lower viral activity without antivirals (1 year-77.3%, 3 year-64.5%, and 5 year-58.3% vs. 1 year-84.0%, 3 year-73.4%, and 5 year-68.0%, respectively). The survival rate of patients with liver cirrhosis (LC) at baseline was significantly lower than that of those without LC. Cirrhotic patients taking antivirals before ML diagnosis had a worse prognosis than who did not.
Conclusions
High viral activity in CHB patients with ML is useful in predicting the prognosis for survival.
Summary
The crude incidence of malignant lymphoma with chronic hepatitis B virus has increased steadily. High viral activity in chronic hepatitis B patients with malignant lymphoma is useful in predicting the prognosis for survival.

Published: May 2022

Abstract
Background: Substance use is known to be more common among street children. Sometimes responsible for the runaway and repeated run-away behavior. To be able to reinsert these children, the reasons why there joined the streets, why they use substance and their pattern of substance use need to be understood.Methods: We conducted a descriptive cross-sectional study in February 2021 in the streets of Yaounde. We did a semi-structured interview of 159 street children using a sociodemographic questionnaire made of open questions and, the Alcohol, Smoking, and Substance Involvement Screening Test, version 3.0. The data were analyzed using R 4.1.0 for Windows.Results: All street children were male. The most common reason for joining the streets was, questing for money, reported by one-quarter of the children. Since their arrival in the streets, 60% of them ever used a substance, of which half used a substance because of peer pressure. The most commonly used substance was cannabis (36.48%), followed by Tobacco (35.85%). 14.47% and 11.32% were high risktobacco and cannabis users respectively. Conclusion: Substance use and risky substance use suggestive of substance use disorders are highly common among street children of Yaounde. This needs to be addressed to facilitate their reinsertion as shown in other studies. The mechanisms that lead to the absences of girls in the streets should also be explored to see if they can be applied to boys.
Minimal Catalytic Assemblies Can Oscillate Utilizing Feedback Loops

Published: May 2022

Abstract
The light-dark cycles created from Earth’s rotation helped in the emergence of extant cellular life that integrates evolved oscillatory networks to control circadian rhythms, cell division, metabolism and so forth. Out of equilibrium networks of organic chemical reactions with dynamic self-assembled structures that emerged from Darwin’s nutrient-rich warm pond played crucial roles in spawning the protolife under a fluctuating environmental condition. Dynamic chemical networks with simple chemicals that can display emergent network dynamics can contribute to our understanding of complex behaviours from simple organic reactions. Here we have designed a single amino acid-based system that could self-assemble and oscillate under non-equilibrium conditions, importantly in the absence of evolved biocatalysts. The two-component based building block exploits pH driven non-covalent assembly and time-delayed accelerated catalysis from self-assembled state to install orthogonal feedback loops with a single batch of reactants. Modifications of these autonomous systems from purely synthetic molecules can enable the design of exceptional life-like materials and evolving systems with acute spatiotemporal control of properties.

Published: May 2022

Abstract
BackgroundRisk of choledocholithiasis should be assessed in every patient who must undergo cholecystectomy to define the next step. American Society for Gastrointestinal endoscopy (ASGE) proposed a stratified predictor scale of choledocholithiasis. MethodsTo describe our experience managing patients with intermediate risk of choledocholithiasis according to the ASGE guidelines and actual presence of bile duct stones in magnetic resonance cholangiopancreatography. A retrospective observational study with a prospective database was conducted. Analysis included socio demographic data, laboratory values ​​and imaging. Bivariate, multivariate and ROC analysis was performed. Results 327 patients had intermediate risk for choledocholithiasis. Half the patients were at least 65 years old. 24.8% were diagnosed with choledocholithiasis. Bile duct dilation was documented in only 3.06% of cases. Diagnosis of choledocholithiasis is associated with age OR: 1.87 (p 0.02), alkaline phosphatase OR: 2.44 (p 0.02) and bile duct dilation > 6 mm OR: 14.65 (p 0.00). ConclusionsHigh variability in accuracy of imaging techniques results in a large number of patients classified as intermediate risk without choledocholithiasis in cholangio-resonance. Therefore, enhancing the criteria to define intermediate risk for patients in order to optimize resources is of paramount importance.

Abstract
Background
Surgery on the craniovertebral junction (CVJ) presents particular challenges owing to the close proximity of critical neurovascular structures and the brainstem. It is difficult for classic approaches to obtain the extra exposure of neurovascular structures of the CVJ in practice.The surgical approach to the craniovertebral junction (CVJ) offers specific challenges. We explored the feasibility of an endoscope-assisted high anterior cervical approach to the CVJ.
Methods
We quantitatively assessed the surgical corridor to, and extent of exposure of, the CVJ in six cadaveric specimens, using 0° and 30° endoscopes.
Results
The endoscope provided sufficient exposure of neurovascular structures and the brainstem in the CVJ. Resection of the anterior arch of C1 was avoided in minimal anterior clivectomy. After removing the odontoid, greater exposure of the CVJ was obtained.
Conclusion
An endoscope-assisted high anterior cervical approach to the CVJ preserves cervical spine stability while minimizing the risk of neurovascular injury within the surgical corridor.

Abstract
Introduction:
With the upsurge of COVID-19 cases, Lebanese hospitals are overburdened and hospital care was prioritized for COVID-19 patients with the highest probability of poor outcomes. This paper aimed to assess the suitability of residential settings for home isolation and to explore the patient’s ability to adhere to the required precautions measures.
Methods:
All COVID-19 cases reported between February, 21 and the end of June 2020 and who had mild or moderate symptoms, were contacted via phone calls by a healthcare professional to fill out a standardized questionnaire developed to assess the suitability of the residential setting for home care. Inpatient cases were required, before their discharge from the hospitals, to sign consent related to their adherence to the mandatory precautionary measures. They were also asked to complete, on daily basis, the symptoms monitoring log form. A referral system to health facilities was established to manage cases with worsening health status. A collaborative framework to address violations of home isolation rules was also put in place.
Results:
Of the 600 cases assessed, 44.7% of them were isolated in a living building apartment (67.2%) with one entrance (85.5%) including four to eight rooms (71%). Around one-quarter of patients have children (< 5 years) and 75% of them were living with elderly people. Most of the patients confirmed the availability of a well-ventilated single room (96.2%) and a separate bathroom (80.17%). As for infrastructure, more than 90% of patients confirmed the availability of drinking and tank water, heating facilities, electricity, and safe trash elimination. Similarly, more than 90% of them had access to personal hygiene items, disinfectants, and personal protective equipment. The bulk of homes care were rated as easily reachable. As for awareness and ability to self-serving, 94.5% of patients were knowledgeable about the required preventive measures, able to serve themselves and to adhere to the isolation requirements as well. Only 51.8% of them had access to psychological support.
Conclusion:
Proper assessment of the residential setting for home care of COVID-19 cases combined with close monitoring of the adherence of patients to the required precaution measures are highly needed for limiting the spread of infection within the household and the community.
Calibrating the Performance Assessment Mechanism in Virtual Laboratories with Machine Learning: Using a Non-Hierarchical and a Hierarchical Variation
Authors: Zafeiropoulos Vasilis , Kalles Dimitris 
Published: May 2022

Abstract
Science universities are constantly confronted with the challenge of offering efficient lab training to their students while securing their safety and protecting the lab equipment from damages; hence the needs for the development of distance learnings tool for students to be trained virtually and safely in using the various lab instruments and performing experiments. Furthermore, as the students are evaluated for their laboratory performance at the on-site labs, the need for their assessment at the virtual labs is also present; hence the need for an incorporated assessment mechanism in the virtual lab in charge of the evaluation of the user’s performance. For the assessment mechanism to be reliable though and devoid of the designer’s bias, it may need calibration with machine learning. Hellenic Open University has developed its own virtual biology laboratory, Onlabs, which simulates its on-site one for its students to be trained and evaluated at. Considering the evaluation of the user’s performance in Onlabs, it is made with respect to particular experiments and is based on an embedded scoring algorithm. The latter has also been optimized with the use of two separate machine learning methods, particularly a genetic algorithm and an artificial neural network. Moreover, within the context of the experimental procedure of microscoping, the scoring algorithm was redesigned in a hierarchical fashion in order to incorporate background knowledge about the procedure. In this paper, we present the two machine learning methods used for the optimization of the assessment mechanism in a non-hierarchical and a hierarchical variation and compare the results within a particular variation as well as within a particular method.
