Authors: Dhull Vishal , Saini Sumindar Kaur , Singh Sarbjeet , Sharma Akashdeep
Published: October 2022

The global pandemic due to the novel coronavirus (2019-nCoV) is responsible for millions of deaths worldwide. It has been caused by a syndrome related to respiratory organs, namely Coronavirus 2 (SARS-CoV-2), believed to have originated in Wuhan. Pattern analysis of the spread of COVID-19 is critical to provide proper guidelines to the public for their safety and health. The epidemiological dataset of coronavirus is used to forecast a future number of cases using various machine learning models and validated concerning the complete count of globally present cases. The dataset has been compiled using different datasets from Johns Hopkins University, National Health Commission, and the World Health Organization (WHO). The prediction has been able to observe the total cases in 222 nations globally. This paper presents a comparative study of the existing forecasting machine models used on the COVID-19 dataset to predict worldwide growth cases. The machine learning models, namely polynomial regression, linear regression, and Support vector regression (SVR), were applied to the dataset that was outperformed by Holt's linear and winter model in predicting the worldwide cases. However, Facebook's Prophet Model gave the best results. The value of the Root means square error (RMSE) was observed to be 5387.741339, with the Mean absolute percentage error (MAPE) value and correlation coefficient calculated to be 0.0020933 and 0.99998, respectively. Hence, Facebook's Prophet Model is the most promising approach and this prediction of COVID-19 cases can be used for the risk evaluation and safety measures to be taken in corresponding areas globally.

Published: October 2022

Progression in technology and innovation increases internet users, who post their perspectives on social media platforms regarding any product or service. It brings forth significant terms, i.e.,”feedback of users,” termed as sentiments and plays a substantial role for commercial organizations to analyze and find polarity related to their respective services. In Sentiment Analysis, the feature extraction phase is a crucial one that affects the entire process's processing. In the case of high dimensional Real- Time data, it leads to a sparse feature matrix and gives rise to steady processing. In this exploration work, we have proposed an Improved Optimized Feature Sentiment Classifier for Big Data (IOFSCBD) System, which deals with advancing the classifiers by giving improved values in each sort of dataset. Results show better execution of the Improved Optimized Feature Sentiment Classifier for Big Data system System.

Shortening the Time Interval for the Referral of Patients With Soft Tissue Sarcoma to Expert Centers Using Mobile Health: Retrospective Study
Authors: Nannini Simon , Penel Nicolas , Bompas Emmanuelle , Willaume Thibault , Kurtz Jean-Emmanuel , Gantzer Justine
Published: October 2022

Background

According to guidelines, all patients with sarcoma must be managed from initial diagnosis at expert sarcoma centers. However, in everyday practice, the time interval to an expert center visit can be long, which delays presentation to an expert multidisciplinary tumor board and increases the risk of inappropriate management, negatively affecting local tumor control and prognosis. The advent of mobile health offers an easy way to facilitate communication and cooperation between general health care providers (eg, general practitioners and radiologists) and sarcomas experts. We developed a mobile app (Sar’Connect) based on the algorithm designed by radiologists from the French Sarcoma Group. Through a small number of easy-to-answer questions, Sar’Connect provides personalized advice for the management of patients and contact information for the closest expert center.

Objective

This retrospective study is the first to assess this mobile app’s potential benefits in reducing the time interval for patient referral to an expert center according to the initial clinical characteristics of the soft tissue tumor.

Methods

From May to December 2021, we extracted tumor mass data for 78 patients discussed by the multidisciplinary tumor boards at 3 centers of the French Sarcoma Group. We applied the Sar’Connect algorithm to these data and estimated the time interval between the first medical description of the soft tissue mass and the referral to expert center. We then compared this estimated time interval with the observed time interval.

Results

We found that the use of Sar’Connect could potentially shorten the time interval to an expert center by approximately 7.5 months (P<.001). Moreover, for half (31/60, 52%) of the patients with a malignant soft tissue tumor, Sar’Connect could have avoided inappropriate management outside of the reference center. We did not identify a significant determinant for shortening the time interval for referral.

Conclusions

Overall, promoting the use of a simple mobile app is an innovative and straightforward means to potentially accelerate both the referral and management of patients with soft tissue sarcoma at expert centers.

Translating “Printed Texts” into the “Moving Pictures – Film”
Authors: Joshi Ms. Shivani
Published: October 2022

Literature is a mirror to society: a way of imparting knowledge, sharing ideas and thoughts, and bringing revolutions in the civilization. When it comes to literature, the treasure of literature lies in the vernacular language and which needs to be translated into the globally accepted language in order to make it available to each stratum of the society. Traditionally “Translation Literature” means “translating literature of one language to another language in authentic way”, however, there is a surge in research probing the parallels between translation and adaptation process. What is available in the form of printed text in one language is translated not only into the printed text in another language but also into the language of sound and moving objects. This paper attempts to examine how “Literature” in one language translated into “Cinema”. When a book is translated into the film, a scriptwriter makes certain changes by adding the essence through the appropriate dialogue: while working with language, he translates and adapts relevantly for the modern audience - translating a written text from one language into another language and the another medium.

Understanding The Trauma of 1947 India-Pakistan Partition – An Account of Toba Tek Singh
Authors: Choudhary Sejal
Published: October 2022

The year 1947 saw the birth of India’s freedom and the death of its people’s joy, leaving behind slaves of religious chauvinism, communal barbarity and inhumane cruelty. The partition of 1947 was a gruesome and landmark incident in the history of both the nations. The ‘bloody’ line of partition that was drawn by Cyril Radcliffe has not stopped bleeding since 1947. This line, drawn by a man who never visited the nation before, had marked the fate of millions, causing an unceasing chaos which eversince has been the reason behind tension between the two nations today. The two nations that were one community; a community which lived in peace and harmony once. The high spirits of the nation after its victory in the struggle for freedom was supressed by the pain of partition. Author Moni Mohsin, in her literature piece, throws light on the way India won this freedom at the cost of happiness and lives of millions. In her words – “The creation of India and Pakistan in 1947 led to horrific sectarian violence and made millions refugees overnight” (Mohsin). The partition of India was nothing less than a heart cut into two pieces and though wounds will heal, memories will fade but the pain will always reside in the hearts of the families that were destroyed. This grotesque event led by greed for political powers had caused one of the largest massacres and migrations in the history of mankind. Although the partition was a landmark incident in the geopolitical history of India, “Toba Tek Singh” by Sadat Hassan
Sobreingesta de boro durante la época precolombina en las poblaciones de Arica
Authors: Arriaza Bernardo Tomás , Figueroa Leonardo , Standen Vivien , Aravena Natalia , Vizcarra Arnoldo , Contreras Camila
Published: October 2022

In some valleys in northern Chile, the natural water reservoirs used for human consumption contain high levels of boron (> 25 mg/L). In local Pre-Colombian populations, this resulted in overexposure which is harmful to human health, causing gastrointestinal and other issues. Boron levels vary regionally, with the Lluta and Camarones Valleys presenting higher mean values (14 and 25 mg/L, respectively) than the Azapa Valley (1 mg/L). To estimate concentrations in northern Chile’s pre-Columbian populations, we used molecular absorption spectrophotometry to analyze rib samples of 211 individuals from these valleys. All the ancient rib samples presented mean boron values approximately 7 to 23 times higher than the 10.2 mg/Kg reported for modern bone tissue. Levels were highest in inhabitants of the Lluta Valley (235.52 mg/Kg) and Camarones Valley (119.09 mg/Kg), followed by those from the Azapa Valley (69.97 mg/Kg). We conclude that boron overexposure significantly impacted northern Chile’s ancient populations, and the discussions of pre-Columbian settlements and biocultural trajectories should consider water quality.
REFLEXIONAR A PELO: SEXUALIDAD Y NEGATIVIDAD EN LA TEORÍA QUEER ANTISOCIAL
Authors: Martínez Ariel
Published: October 2022

El presente artículo se interesa por la tesis queer antisocial contemporánea. Enfatiza especialmente el llamado a una radicalización de la crítica, ya esbozado por Guy Hocquenghem y puesta en forma por Leo Bersani y Lee Edelman, quienes apuestan por una concepción psicoanalítica de sexualidad que no reconoce mediaciones lingüísticas, identitarias o comunitarias cuando se trata de contener el deseo, la fantasía o la pulsión de muerte. Como figuración epistemológica que nos permite reflexionar sobre la recuperación de la potencia anti-normativa queer, se presentan las indagaciones de Tim Dean sobre el Bareback (práctica sexual sin protección, donde la erotización del contagio del VIH juega un papel capital, fantasmática o literalmente). Muy lejos de miradas patologizantes, se reflexiona sobre el núcleo perverso de la sexualidad, en cualquiera de sus formas, y en los límites irreductibles que ella impone a la razón.

Prevalence and Antimicrobial Susceptibility Pattern of Secondary Gram-negative Bacteria Isolated from Severe Acute Respiratory Syndrome Coronavirus Disease 2 Patients in A Tertiary Care Hospital
Authors: Juliana Alamu , Ramya S. , Leela K.V. , Anusha
Published: October 2022

Prior to the Severe Acute Respiratory Syndrome Coronavirus Disease 2 (SARS-CoV-2) pandemic, the rise in antimicrobial resistance was a major source of concern in public health. However, due to the novelty of SARS-CoV-2 infection during the pandemic, antibiotics were administered prior to laboratory testing for secondary gram-negative bacteria (SGNB) in order to avoid or reduce the occurrence of SGNB infection. The purpose of this study was to investigate the etiology, prevalence, and antimicrobial susceptibility pattern of gram-negative bacteria (GNB) isolated from SARS-CoV-2 positive patients. Respiratory and blood samples were collected from confirmed SARS-CoV-2 positive patients. They were subsequently cultured and bacterial isolates identified according to standard microbiological protocols. Antimicrobial susceptibility testing (AST) was performed and interpreted according to Clinical & Laboratory Standards Institute (CLSI) 2021 guidelines. A total of sixty-four non-repetitive GNB were isolated from respiratory samples and twenty-two GNB from blood samples. K. pneumoniae was the major cause of SGNB, followed by Acinetobacter species. K. pneumoniae had over 60% resistance to β-Lactam combination agents, cephalosporin, and the carbapenem group of antibiotics. In the current study, we observed that K. pneumoniae was the major cause of SGNB and had high resistance to the antimicrobial agents. Hence, it is important that the epidemiology and susceptibility patterns of circulating organisms causing SGNB infection are always monitored to inform clinical treatment and decrease the occurrence of antibiotic-resistant bacteria.

Strategic communication at the European Space Agency: juxtaposing strategy and public attitudes
Authors: Pfleger Axel , Gerber Alexander , Struck Alexander
Published: October 2022

This case study analyses the efficacy of the European Space Agency's (ESA) strategic communication through a content analysis and an online attitudes survey in Germany. Our findings generally indicate low efficacy as ESA's communication strategy strongly focusses on press agentry, and is not managed in a sufficiently strategic manner. ESA pays little attention to evaluation and lays emphasis on targeting ‘the general public’. By contrast, we reveal a diversity of attitudes towards ESA among various publics. In light of this disconnect from best practice and public attitudes, we argue for a more inclusive approach which maximises public participation and introduces a more diverse and evidence-based science communication portfolio so as to make ESA's communication more efficacious and sustainable.
The Wretched of the Work: Anger, Fear, and Hopelessness as Impacts of Experiencing Workplace Racism in British Columbia, Canada
Authors: Asey Farid
Published: October 2022

Drawing inspiration from Frantz Fanon’s work on the colonization of racialized subjects, this article illuminates how racial discrimination impacted the wretched of the work, in reference to a group of racialized civil servants, in primarily White institutions of public service in British Columbia, Canada. Specifically, using data from twenty-five in-depth qualitative interviews, the article presents findings on the affective impacts of workplace racism on this group of participants. In this regard, anger is discussed as internalized, nonviolent and pent-up frustration over oppressive everyday microprocesses that presented significant workplace barriers to racialized workers. Subsequently, fear is outlined as shaped by the lingering concerns on the part of racialized subjects over the very real prospects that their employers could retaliate against participants using any pretext and at any given time. Lastly, hopelessness is explicated as the feeling of disempowerment driven by the belief that workplace inequities would persist irrespective of what participants did to seek equal and respectful treatment at work. Ultimately, through outlining findings as anger, fear, and hopelessness, this article adds to the existing body of scholarship on how workplace racism not only leaves an indelible mark on racialized targets but also why it wreaks havoc in employment relations, further reinforcing existing empirical literature on the debilitating impacts of workplace racism. Lastly, in view of the fact that racialized public servants have received scant research attention, the findings underscore the need for publicly-funded employers to address White supremacy and institutional domination in their midst on a priority basis.
Op-Ed: Failing to Bend the Arc of the Moral Universe? Dr. King, Newton, Piaget, and Social Work
Authors: Castillo Jason , Lundahl Brad , Moleni Kristina , Blackman Laurie
Published: October 2022

To achieve a more just universe, the momentum and historical forces of racism, sexism, heterosexism, privilege, etc. must be met with equal and opposite forces through policies, structures, and the courageous acts and voices of many. Dr. King’s claim that “the moral universe bends toward justice” is joined with Newton’s Laws of Motion where arcs only bend through external forces. Bending the arc necessitates a large membership, including social workers. Membership in a group confers advantages while simultaneously ushering in implicit biases against those outside of the group ultimately disadvantaging both groups. Educating tomorrow’s social workers necessarily involves ingroup and outgroup membership, instructors and students. We argue well-meaning social work educators often act against Social Work’s mission of producing a cadre of individuals who will pull the arc toward social and economic justice. Students in social work programs, eager to pull on the moral arc, are often criticized for being inexperienced and not further along in their “woke” development. Criticism may discourage students, thereby losing needed ingroup members. Students are canceled. Algebra, evolutionary theory, and cognitive development theories provide guidelines for unifying social work educators and students to promote Dr. King’s vision.

Published: October 2022

Mathematical creative thinking ability is essential to be mastered by students to create good learning results and achievement. To install creative thinking in students' minds, they are highly requested to apply an innovative learning model. Among innovative learning models, project-activity-cooperative learning-exercise (PACE) is the one to be considered suitable for improving the students' mathematical creative thinking. This study is an experimental research using a pretest-posttest control group design. It was conducted in three classes of IKIP Siliwangi students by applying different learning models. The first class was given the PACE model treatment with Geogebra, the second class was given the PACE model treatment, and the third class was given direct learning. The instrument used tests. Based on the data analysis, we can conclude that there are differences in improving creative thinking abilities among the students who get the PACE model learning with Geogebra (PACE-G), the PACE model, and direct learning (DL). The improvement of creative students who get PACE and PACE-G models is better than those who get DL. The progress of students' mathematical creative thinking abilities obtained from PACE and PACE-G models is a high category. In contrast, improving students' creative thinking abilities who acquire DL is categorized as a medium.
The political economy of budget reforms: Evidence of an emerging market
Authors: Alnesafi Awwad
Published: October 2022

The purpose of the paper was to investigate the socio-economic and political processes that influenced Kuwait’s budget reforms in the wake of declining oil prices. A qualitative study and a literature review were adopted and informed by political economy theory to generate in-depth insights into similar and different socio-economic and political processes that influenced the adoption and implementation of a range of budget reforms in Kuwait. The study revealed that the budget reforms in Kuwait, as part of the austerity measures, were influenced by the dwindling oil revenues; the entrenched welfare system; the power struggles between the state actors; and the strategic partnerships and coercive role of supranational agencies, especially in creating an enabling environment for global capitalism. The paper demonstrates how the socio-economic and political environment influences and is influenced by the strategic accounting choices and practices adopted and implemented. Budget reforms in Kuwait were proposed to address the socio-economic and political realities of the day, but also, the reforms prepared fertile grounds to support global capitalism. The paper contributes to the debate on the political economy and how it is relevant in understanding the socio-economic and political processes involved in the adoption and implementation of accounting changes, especially in developing countries.

Foundational Conditions Enabling Participatory Riverine Management in Watersheds of Two Geographically and Regulatorily Disparate States: A Mixed Methods Study
Authors: Burbach Mark E. , Eaton Weston M. , Kennedy Stephanie M. , Brasier Kathryn
Published: October 2022

Increasing complexity of riverine management is driving the need for
more participatory approaches in which a wide range of stakeholders
inform management actions. The foundational conditions of successful
stakeholder engagement in participatory riverine management include the
stakeholders’ familiarity with, trustworthiness of, shared vision with,
and perceived competence of agencies involved in riverine management. We
employ an embedded experimental mixed-methods approach to gain insight
into two key stakeholder group’s (agricultural producers and non-farm
households) perceptions of foundational conditions of successful
stakeholder engagement in participatory riverine management in
watersheds of two geographically and regulatorily disparate states.
Overall, ratings for familiarity were often contrary to ratings of other
three conditions. Contrary to previous research our findings suggest
that familiarity does not necessarily lead to stakeholder perceived
trustworthiness, shared vision, and competence of those involved in
riverine management. These findings are important for participatory
processes; for example, trust and shared vision without familiarity may
inhibit the active involvement of diverse stakeholders in participatory
processes that is needed for improving management of complex riverine
systems. Our findings suggest agencies and groups involved in riverine
management prioritize developing stronger relationships with
agricultural producers to improve on these foundational conditions.
Agencies and groups involved in riverine management rated low on
familiarity should consider campaigns to increase stakeholders’
familiarity with them to leverage the generally high ratings on the
other three foundational conditions. Future research should explore
these contrary findings and their relationships to active involvement in
participatory riverine management.
Meandering reduces the influence of stream orientation on riparian shade
Authors: Rutherford J. Christopher
Published: October 2022

Restoring riparian shade helps maintain healthy stream ecosystems and
computer models are helpful in guiding restoration. The effects of
meandering and orientation on shade to direct and diffuse lighting was
investigated using a simplified model of riparian vegetation. Previous
studies have shown that straight streams oriented east-west (EW)
experience higher lighting than those oriented north-south (NS).
Meandering decreased reach-averaged direct lighting in EW valley streams
but increased lighting in NS valley streams. When meander amplitude
equalled 50% of meander wavelength, lighting of streams in EW and
NS-aligned valleys was similar. Meandering and valley orientation had
little effect on diffuse lighting. In EW valleys lighting was highest at
stream bends and a strategy to reduce lighting quickly would be to
prioritise planting of tall vegetation on bends. In NS valleys lighting
was lowest at bends, suggesting the opposite planting strategy. Shade
exceeding 70%, a criterion for preventing nuisance aquatic plant
growths and stressfully high water temperatures, occurs in ‘typical’
meandering streams on cloudless, mid-summer days at mid-latitudes once
H/ W exceeds about 2. The model over-simplifies riparian
vegetation and the effects of canopy shape and overhang merit further
investigation.

Published: October 2022

In hemisphere point temperature (Thp) measurement of continuous casting mold flux, the evaporation of volatiles under high temperature will have a strong impact on the results. Based on the comprehensive analysis of hemisphere point method and its influencing factors, the corresponding volatile-containing mold flux and non-volatile mold flux were selected to get Thp with different heating rates. Combined with the Thp measurement and TG-DSC results, the effect of relevant factors during measuring process were analysed and the way to characterize and evaluate the effects were suggested. Furthermore, an improved method of mold flux melting point test was put forward. The results showed that for non-volatile mold flux, the temperature hysteresis had a greater effect than heat transfer delay and fractional melting. As for the mold flux with volatile, the effect of evaporation was greater than other factors. Traditional hemisphere-point method is no longer suitable for the volatile mold flux. In order to get through this problem, improved methods were proposed. One is measuring Thp traditional way, correcting the composition at the Thp, and corresponding Thp with the corrected composition. Another is taking the initial composition, revising the hemispherical point temperature Thp, and matching the revised Thp with the initial composition.
A new process for extracting vanadium by direct calcification using the heat of molten vanadium slag
Authors: Qu J.-W. , Zhang T.-A. , Lv G.-Z. , Chen Y.
Published: October 2022

A novel technology for extracting vanadium from molten converter vanadium slag was studied at the laboratory scale by oxidation and calcification. The effect of the cooling method, CaO addition, and reaction time on the phases of calcified vanadium slag was studied. Under the action of oxygen and CaO, the molten vanadium slag underwent calcification reaction to form acid-soluble calcium vanadate phase and the feasibility of its main chemical reaction was calculated by Factsage8.1. The calcified vanadium slag was leached by H2SO4 solution and characterized by the XRF, XRD, SEM, and EDS techniques. Compared with the traditional process, the new process saved much energy, and it was faster and more efficient. The XRD results showed that CaV2O5, Ca7V4O17, and Ca3V2O8 were gradually formed in the molten vanadium slag with increasing CaO addition. However, when too much CaO was added, Ca2SiO4 and CaTiO3 were also formed. These phases wrapped part of the vanadium and reduced the leaching rate of vanadium. When the mass ratio of Ca to V was 0.75, under the optimal acid leaching conditions (particle size of calcified vanadium slag less than 0.075 mm, leaching temperature 90 ?, H2SO4 concentration 200 g.L-1, liquid-to-solid ratio 6:1 ml.g-1, leaching time 60 min, and stirring speed 300r.min-1), the leaching rate of vanadium from calcified vanadium slag could exceed 90%. The new process not only saved energy and reduced emissions, but also reached the average level of the existing vanadium extraction process.
Atmospheric curing of zinc sulfide concentrate by sulfuric acid below 300°C

Published: October 2022

Because the traditional roasting-leaching-electrowinning zinc hydrometallurgy process has a small sulfuric acid sales radius and a high inventory pressure, the process of direct leaching zinc concentrate is gaining popularity, but the pressurized leaching process is a high-pressure condition, which requires strict equipment material and high safety requirements. Furthermore, the atmospheric leaching efficiency is low and generally introduces impurities and chloride ions, which increase the cost of subsequent decontamination. Therefore, a new environmentally friendly hydrometallurgy extraction method of zinc was proposed: an atmospheric pressure medium temperature sulfuric acid curing-leaching process. Under open-air conditions, zinc sulfide concentrate was cured with sulfuric acid at different acid-to-ore ratios and heated to 220?~260? for a different time, then the cured product was leached. The effects of temperature, curing time, acid-to-ore ratio, and sulfuric acid concentration on the leaching ratio of zinc (?Zn) were studied. The results demonstrated that ?Zn could reach as high as 98.23% under the optimized conditions of temperature 240?, curing time 2.5 hours, acidto-ore ratio 1.4:1, and sulfuric acid concentration 60 wt.%. The leaching residue ratio is 6%, with silicate accounting for the majority of it. The kinetic results support the shrinking core model, which is controlled by an interface chemical reaction with an apparent activation energy of 43.158 kJ/mol.

As a refractory industrial solid waste, high-alumina fly ash is discharged into nature in large quantities, causing serious environmental harm. The extraction of valuable components, such as aluminum, from high-alumina fly ash has become a research hotspot at home and abroad. The shortcomings of traditional alumina extraction from high-alumina fly ash include long technological processes, large amounts of waste acid and alkali, and serious equipment corrosion. A novel method for alumina preparation by electrotransformation AlCl3 solution(EAS) under NH4Cl catalysis with injected CO2 has been proposed by Northeastern University. The process has advantages, such as short flow and no waste acid discharge. In this study, the influence of initial NH4Cl concentration in the cathodic chamber on solution pH, phase and morphology of electrotransformation products, phase, D(50) and D(90) of roasting products, and Al recovery rate were examined. Simultaneously, EAS was examined and compared with and without injected CO2, as well as EAS under NH4Cl catalysis with and without injected CO2. The results showed that, when the solution in the cathodic chamber was NH4Cl with CO2 injection, with electrotransformation time extension, pH increased slowly and the morphology of electrotransformation products were all rough and fluffy block structures. Increasing initial NH4Cl concentration effectively improved the product crystallization states, roasting products D(50) and D(90), and Al recovery rate.

Introduction/Objective. Colorectal cancer (CRC) is currently the third most common cancer in incidence in the United States and accounts for about 8.5% of all cancer related deaths. Our study aim was to determine the parameters that contribute to the survival of CRC patients with hepatic dysfunction, attention to the positive effects on survival when the most appropriate clinical approaches. Methods.Patients with CRC, diagnosed with hepatic dysfunction, and who were followed up in our inpatient service in the last two years were included in our study. Survival rates were analyzed starting from after the development of hepatic failure. Results. A total of 57 patients were included in the study, 44 (77.2%) were colon carcinoma, and 13 (22.8%) were rectal carcinoma patients, and 14 (24.56%) were female. Bile duct dilatation (BD) was detected in 19 (33%) of 57 patients with imaging methods. The median OS was calculated as 4 vs. 1.4 months in patients with BD compared to patients without BD (p < 0.001). Survival times were significantly higher in patients with BD compared to those without dilatation, and in patients without renal failure compared to those with renal failure. Conclusion. In cancer patients with hepatic dysfunction, those with additional renal failure had shorter survival times and a worse prognosis. The longer survival of patients with BD was attributed to the optimal timing of the percutaneous transhepatic cholangiography insertion, close clinical and inflammation marker follow-ups, and early prevention of external biliary drainage, therefore preventing a possible septic complication early on.

An emergency caused by the COVID-19 pandemic affected the rethinking of existing healthcare systems. The increased need for hospital beds appeared short after the outbreak of the pandemic and the solution was to adapt the existing buildings, primarily public ones. Among all, sports buildings, i.e. sports halls were successfully used around the globe for conversion into hospitals. Topic of the paper was to investigate whether sports halls in Serbia, which were also used as temporary hospitals, are suitable for conversion in terms of energy consumption needed for achieving thermal comfort. Two case studies were analysed. The energy simulations were done using the DesingBuilder software. The results of thermal comfort summary and energy consumption led to the conclusion that this building type in Serbia could be successfully used for hospital purposes. Although the multiple increase in energy consumption was noted during the heating period, the results were within the limits required by both national and international standards.

The paper examines outdoor thermal comfort in summer in the multi-family housing area Duvaniste in the city of Nis, Serbia, combining objective and subjective evaluation assessments. Objective evaluation obtained field measurements of microclimatic parameters at selected sites and mean radiant temperature, predicted mean vote, and psychological equivalent temperature calculation using RayMan software. Subjective methodology assessment is performed using survey questionnaires based on thermal sensation vote and overall comfort vote. The paper aims to find the correlation between measured and calculated parameters on one side and Thermal Sensation Vote values. The results show that air temperature significantly correlates to human thermal sensation in the subject area. Obtained results also indicate high prediction accuracy of psychological equivalent temperature in the outdoor thermal comfort evaluation in summer. Finally, to feel comfortable, neither warm nor cold, in continental climate regions with hot summer conditions, the neutral psychological equivalent temperature should be between 15-24.3 ?.
Non-Fickian transport models for characterising the sediment suspension in unsteady flows
Authors: Nie Shiqian
Published: October 2022

Non-Fickian transport of suspended sediment has been observed at field and laboratory scales. Such as turbulent bursting, resulting in complex dynamics for the sediment particles movement. The erosion and deposition of sediment have an impact on the hydraulic engineering and environment. This study makes an attempt to develop the variable-order fractional advection-diffusion equation (VOFADE) and variable-order Hausdorff fractal derivative advection-diffusion equation (VOHADE) models to describe the vertical distribution of suspended sediment in unsteady turbulent flows. From a classical viewpoint, the distribution of the concentration in sediment-laden flows is determined based on Fick?s first law. However, the vertical diffusion of suspended particles exhibits the non-locality/space scale dependency and history memory/time scale dependency properties due to turbulent bursting. Moreover, previous literatures have indicated that turbulence structure changes with the water depth. Hereby, we employ the space-dependent VOFADE and VOHADE models to describe the vertical diffusion of suspended sediment in unsteady flows, and further test its applicability with the experimental data. Numerical simulation results confirm that the VOFADE and VOHADE models give a better agreement with the experimental data and can well characterise the space-dependent anomalous transport. Hence, the models proposed by this study may help to provide a powerful mathematical physical model in the quantification of suspended sediment transport.

Tannase have been widely secreted industrially by fungi using tannin rich agricultural waste as substrate. Aspergillus niger SCSGAF0145, was used for the secretion of tannase using groundnut shell as substrate under submerged fermentation. The crude tannase secreted was precipitated out using ammonium sulphate and purified on Sephadex G-150. Kinetic parameters of the secreted tannase were determined using tannic acid as substrate. The estimated biomass weight, tannin concentration, gallic acid concentration and tannase activity of the crude enzyme after fermentation was 81.00±0.08 mg, 1.31±0.01 mg/mL, 0.67±0.03 µg/mL and 6.04 U/mL respectively. The purification fold and enzyme yield after purification were 13.44 and 47.86%. The purified enzyme showed maximal activity at a pH of 5.5 and temperature of 35oC while producing Km and Vmax of 0.43 moles/L and Vmax is 21.55 U/mL respectively using tannic acid as its sole carbon source. In conclusion, Aspergillus niger SCSGAF0145 secreted tannase of high activity using groundnut shell as source of tannic acid which could be utilized for various industrial purposes.
