HEAT TRANSFER ENHANCEMENT AND SCALE FORMATION: EXPERIMENTAL STUDIES IN FALLING FILM EVAPORATORS USING COPPER METAL FOAM
Authors: Jayakumar Arjun , Annamalai Mani
Published: November 2022

Performance enhancement of horizontal tube falling film evaporators using thin metal foam was studied. A copper foam was brazed over the outer surface of a copper horizontal tube and used in the falling film evaporator of a desalination system. It was observed that the distillate production and heat transfer rate was enhanced by more than twice with the modified tube. Effect of feed rate, feed temperature, and subcooling on distillate production was studied for the copper foam-wrapped heat exchanger tube evaporator. A metal foam-wrapped heat exchanger tube was also used to study the effect of scale formation. The effects of temperature, flow rate, and seawater turbidity on scale formation was studied. Total scale deposit weight was observed after every 16 h of operation for a total run time of 128 h. It was observed that scale formation reduces with an increase in flow rate and increases with seawater temperature. It was also observed that scale formation is lower when the system is operated with seawater of low turbidity. The heat transfer enhancement surface promotes scale formation due to the increase in metal surface area in contact with seawater as in the copper foam-wrapped tube. Energy-dispersive X-ray spectroscopy and scanning electron microscopy were applied to investigate the mineralogy and microstructure of the deposits.
Upper bounds for the three-dimensional seismic active earth pressure coefficients
Authors: Santana T. , Antão A. , Guerra N. , Vicente da Silva M.
Published: November 2022

A numerical implementation of the upper-bound theorem of limit analysis is applied to determine two-dimensional (2D) and three-dimensional (3D) active horizontal earth pressure coefficients considering seismic actions through a horizontal seismic coefficient. Results are obtained for vertical wall, horizontal soil, different friction angles of the soil, soil-to-wall friction ratios, horizontal seismic coefficients and wall width-to-height ratios. The few cases for which 3D active earth pressure coefficients are available in the literature using upper-bound methods were used for comparison with the corresponding earth pressure coefficients obtained in this study. This showed a general improvement of these results, which allows expecting a good accuracy for the set of cases studied. The ratios between the 3D and 2D horizontal active earth pressure coefficients are found to be practically independent of the soil-to-wall friction ratio. An equation is proposed for calculating these ratios. This equation can be easily used in the design of geotechnical structures requiring the determination of 3D active earth pressure coefficients.

Background

Prospective randomized trials investigating treatments and outcomes in anti–glomerular basement membrane (anti-GBM) disease are sparse, and validated tools to aid prognostication or management are lacking.

Methods

In a retrospective, multicenter, international cohort study, we investigated clinical and histologic parameters predicting kidney outcome and sought to identify patients who benefit from rescue immunosuppressive therapy. We also explored applying the concept of the renal risk score (RRS), currently used to predict renal outcomes in ANCA-associated vasculitis, to anti-GBM disease.

Results

The final analysis included 174 patients (out of a total of 191). Using Cox and Kaplan–Meier methods, we found that the RRS was a strong predictor for ESKD. The 36-month renal survival was 100%, 62.4%, and 20.7% in the low-risk, moderate-risk, and high-risk groups, respectively. The need for renal replacement therapy (RRT) at diagnosis and the percentage of normal glomeruli in the biopsy were independent predictors of ESKD. The best predictor for renal recovery was the percentage of normal glomeruli, with a cut point of 10% normal glomeruli providing good stratification. A model with the predictors RRT and normal glomeruli (N) achieved superior discrimination for significant differences in renal survival. Dividing patients into four risk groups led to a 36-month renal survival of 96.4% (no RRT, N≥10%), 74.0% (no RRT, N<10%), 42.3% (RRT, N≥10%), and 14.1% (RRT, N<10%), respectively.

Conclusions

These findings demonstrate that the RRS concept is transferrable to anti-GBM disease. Stratifying patients according to the need for RRT at diagnosis and renal histology improves prediction, highlighting the importance of normal glomeruli. Such stratification may assist in the management of anti-GBM disease.

Published: November 2022

Abstract Objectives: To present the data generated at our hospital by comparing the operative characteristics and surgical results of patients who applied to the clinic and emergency room due to ovarian cyst and underwent laparoscopy or laparotomy. Materials and Methods: In this retrospective study, patients who underwent cystectomy, oophorectomy, and hysterectomy salpingo-oophorectomy due to ovarian cysts were compared in two groups, comprising laparoscopy and laparotomy. Evaluated retrospectively in this study were 443 patients operated on due to benign ovarian cyst diagnosis. Data in the patient files were analyzed in terms of age, cyst size, postoperative hemoglobin, postoperative white blood cell count, operating time, hospital stay, and surgical site infection. Results: Postoperative surgical site infection was significantly higher in the laparotomy group. The risk of surgical site infection was RR= 4. 5 (1.74–11.67) times higher in those who underwent laparotomy when compared to laparoscopy. The duration of hospital stay was lower in the laparoscopy group for all operation types (oophorectomy, cystectomy, and hysterectomy salpingo-oophorectomy). The cyst sizes of the patients who underwent hysterectomy salpingo-oophorectomy were significantly more significant in the laparotomy group. The duration of hospital stay in the patients who underwent hysterectomy salpingo-oophorectomy was significantly longer when compared to the laparoscopy group, while no significant difference was found in the oophorectomy and cystectomy patients. The need for blood transfusion was significantly lower in the laparoscopy group for all operation types. Conclusions: It was concluded that the duration of hospital stay, surgical site infection, need for blood transfusion, and operating time was less in patients who underwent laparoscopy. Laparoscopic surgery methods can be safely recommended for rapid and effective treatment of benign ovarian cysts with cystectomy, oophorectomy, and laparoscopic hysterectomy about hospital stay and complications.

The verbal structure in English synthetic compounds
Authors: Iordăchioaia Gianina , Alexiadou Artemis , Alexiadou Artemis
Published: November 2022

The question whether synthetic compounds should be analyzed as including a verbal core or as root compounds has issued a long theoretical debate in the linguistic literature since the ‘70s. It is precisely their mixed properties that make this debate so difficult to settle. We investigate compounds headed by suffix-based deverbal nouns and propose that they are ambiguous between true synthetic compounds, which include verbal structure, and root compounds. We trace this ambiguity back to Grimshaw’s (1990) distinction between argument structure nominals (realizing verbal arguments) and result or simple event nominals (which do not realize verbal arguments). The true synthetic compounds are headed by argument structure nominals and realize the verb’s internal argument as a non-head (e.g. book reading, book reader), but deverbal nouns may also head root compounds when interpreted as simple event or result nominals and realize a modifier as their non-head (e.g. police questioning). We account for the differences and similarities between synthetic compounds and argument structure nominals in the framework of Distributed Morphology and show how Voice-related properties account for further characteristics of synthetic compounds concerning event implication and accommodation of idioms.

Elektorenkefalográfiával (EEG) a kognitív folyamatok jó időbeli felbontással követhetők, a hordozható készülékek valós környezetben történő adatrögzítést is lehetővé tesznek. A regisztrátumok értelmezéséhez azonban vizsgálni kell, hogy a laboratóriumi körülmények között feltárt EEG jellemzők érvényesülnek-e komplex környezeti hatások mellett. Három különböző nehézségű feladat közben rögzítettük egyetemisták EEG aktivitását, a feladatok eredményét és a résztvevők szubjektív értékelését. A regisztrátumok nagyfokú egyéni variabilitást mutattak, ráadásul az egyéb hatásokra (például kialvatlanság) adott válaszok akár ellentétesek is lehettek, de a figyelem és az alfa aktivitás jellemzői elvárásainknak megfelelően változtak. A feladatok eredményére egyik EEG jellemző se utalt megbízhatóan. Az EEG-t a tanulási folyamat értékelésére egyéb pedagógiai értékelő módszerekkel kiegészítve érdemes alkalmazni.

Published: November 2022

Dementia is a syndrome characterized by multidomain acquired chronic cognitive impairment that has a profound impact on daily life. Neurogenerative diseases such as Alzheimer's disease or nondegenerative diseases such as vascular dementia are considered to cause dementia. The need for further diagnostic improvement originates from the prevalence of these conditions, especially in developed countries with a predominance of the elderly population. Today, the diagnosis and follow-up of all neurodegenerative diseases cannot be performed without radiological imaging, primarily magnetic resonance imaging (MRI). The introduction of 3T MRI and its modern techniques, such as arterial spin labeling, has enabled better visualization of morphologic changes in dementia. For better diagnosis and follow-up in patients with dementia, various semiquantitative scales have been designed to improve the accuracy of assessment and decrease interobserver variability. Moreover, there is a growing need for MRI in the assessment of novel therapies and their side effects. To better apply MRI findings in the diagnosis of both already developed dementia and its early stages, the aim of this paper is to review the available literature and summarize the specific MRI changes.

A high-level method was obtained to solve the SEI model problem involving Symmetrization measures in numerical calculations through the Implicit Midpoint Rule method (IMR). It is obtained using Non-Standard Finite Difference Schemes (NSFD) with Extrapolation techniques combined. In solving differential equation problems numerically, the Extrapolated SEI model method is able to generate more accurate results than the existing numerical method of SEI model. This study aims to investigate the accuracy and efficiency of computing between Extrapolated One-Step Active Symmetry Implicit Midpoint Rule method (1ASIMR), Extrapolated One-Step Active Symmetry Implicit Midpoint Rule method (2ASIMR), Extrapolated One-Step Passive Symmetry Midpoint Rule method (1PSIMR) and the extrapolated Two-Step Passive Symmetry Midpoint Rule method (2PSIMR). The results show that the 1ASIMR method is the most accurate method. For the determination of the efficiency of 2ASIMR and 2PSIMR methods have high efficiency. At the end of the study, the results from the numerical method obtained show that Extrapolation using Non-Standard Finite Difference has higher accuracy than the existing Implicit Midpoint Rule method.

Published: November 2022

Qualitative content analysis can be applied to analysing textual words written in different types of reflection assignments. Thus, the aim of this research is to investigate the adoption of problem-based learning (PBL) learning to understanding the knowledge and level of awareness of chemical engineering students regarding graduate unemployment in Malaysia. Participants are 88 second-year students enrolled on the Differential Equation course at the National University of Malaysia. With technological breakthroughs in computerised text analysis that enable researchers to collect and analyse large amounts of textual data, content analysis employing an inductive approach is used to analyse students’ PBL reflective writing which expresses whether all the main factors of graduate unemployment can be identified. The result reveals that almost 80% of participants were unable to meet the requirement of the first stage of PBL, which is to identify the critical learning issue i.e., unemployment factors. This group of students only managed to identify person-related factors associated to unemployment: working experience and soft skills. Only 15 participants, however, have successfully identified all six factors influencing graduate employability. Practical learning, entrepreneurial skills, internal audit and basic qualifications of graduates, along with soft skills and working experience are the main components of the higher education curriculum that have a significant impact on the unemployment problem of graduates in Malaysia if they are revised. The findings have important implications for how the institution can properly plan and take appropriate actions to raise unemployment awareness among students at an early stage of their study.

Published: November 2022

With the development of industry, the need to improve the efficiency of oil coolers is particularly increasing, due primarily to the rising cost of equipment, as well as increased attention to the issues of resource and energy saving. Oil coolers should not only perform the required functions of oil cooling, but also be as reliable and environmentally friendly as possible. Meanwhile, the majority of serial oil coolers are designed on the basis of outdated technical solutions, and this predetermines the levels of efficiency and reliability of their work as not corresponding to modern requirements. In this connection, the issues of hydrodynamics and heat exchange in finned tubes of oil coolers and refinement of methods of their calculation are relevant both for modernization of existing devices and for design of new oil coolers.

Published: November 2022

The main goal of the study is the atomistic determination of the static stress-strain state at the crack tip in isotropic and anisotropic linearly elastic materials by the molecular dynamics method implemented in the open source LAMMPS (Large-scale Atomistic/Molecular Massively Parallel Simulator). An extensive class of computational experiments has been carried out for a single-crystal copper specimen with a central crack in the LAMMPS. The circumferential distributions of the stress tensor components obtained by molecular dynamics are compared with the angular distributions of brittle fracture continuum mechanics, i.e. with Williams’ analytical solution to the problem of an infinite plate loaded with a central crack in a linearly elastic isotropic material. The comparison of the angular distributions of the stress tensor components gained in the framework of atomistic modeling and the angular distributions obtained from the classical solution of continuum mechanics has shown that, at the nanoscale level, the stress fields are in good agreement with their macroscopic values.

Published: November 2022

The paper presents an exact solution to the boundary value problem describing the steady-state unidirectional flow of a viscous incompressible fluid. The fluid moves in an infinite horizontal strip (infinite fluid layer). The fulfillment of the no-slip condition is postulated at the lower boundary of the viscous fluid layer. At the upper boundary, which is assumed to be rigid, non-uniform velocity distribution is specified. The deformation of the free boundary is neglected due to the use of the rigid-lid boundary condition. The exact solution to the equations of the hydrodynamics of incompressible fluids automatically satisfies the continuity equation (the incompressibility equation). The velocity function is harmonic in this case. The simplest exact solution satisfying the Laplace equation is constructed, which takes into account the features of the velocity field along the transverse (vertical) coordinate and one of the longitudinal (horizontal) coordinates. The paper analyzes the topological properties of the velocity field, the tangential stress field, the vorticity vector, specific kinetic energy, and specific helicity.

The paper presents the results of studying the mechanical behavior of laminated carbon-fiber-reinforced plastic under complex low-velocity impact three-point bending followed by cyclic tension. An integrated approach to studying damage accumulation patterns is implemented with the use of state-of-the-art testing and diagnostic equipment. The residual fatigue life of the composite is related to the intensity of preliminary impact bending. The fields of temperature distribution in the active zone of the samples during the tests are shown. Data on damage accumulation obtained by recording acoustic emission signals are presented. Relation of the change in the recorded acoustic response signals to infrared thermal scanning data has been detected, which is supported by the results of an experimental study. The use of additional equipment for infrared thermal scanning and recording of acoustic emission signals gives a complete picture of damage accumulation and failure in composite materials, with a good agreement with experimental data.

The study explore the legal and doctrinal sources, materials of meetings (congresses) of authorities, members of the public, related to the field of countering the development of epidemics, published during the existence of the USSR (19221991) and in modern Russia. The construction of a universal legal model of socially useful behavior of an individual should be organized based on the conditions that contribute to ensuring the individuals compliance with formal requirements (empirical perception of risk, degree of trust in formal rules, and presence and strength of the influence of factors-obstacles). The following principles of functioning of the desired model were proposed: (1) the principle of a single source of origin, non-contradiction and factual validity of the application of special rules of conduct when threatened with the spread of dangerous diseases, (2) the principle of scientific validity of additional restrictions, prohibitions, and obligations, (3) the principle of systematic preventive work, and (4) the principle of rational planning for the preparation and use of human and material resources of public organizations of volunteers to prevent epidemiological emergencies.

BACKGROUND: Determining the incidence of acute and lethal poisoning with clobazam remains an urgent task of analytical toxicology. The medicinal substance clobazam belongs to the group of benzodiazepines, which is included in the list of psychoactive substances whose turnover is limited because of its high toxicity profile in overdose and abuse.
AIM: To propose a simple, reliable, and sensitive technique for the identification of clobazam and its metabolite in the urine by the modern high-performance liquid chromatography-tandem mass spectrometry (HPLC-QqQ-MS/MS).
MATERIALS AND METHODS: We have described a simple and sensitive HPLC-QqQ-MS/MS method for the qualitative determination of clobazam in the urine.
RESULTS: The retention time in the selected chromatography conditions for clobazam was 5.17 min, and its metabolite (norclobazam) in urine was 4.56 min. The base peaks for clobazam and norclobazam were 259 m/z and 245 m/z, respectively.
CONCLUSION: For the first time, this study provides a validated method of chemical-toxicological examination for poisoning with clobazam by HPLC-MS/MS, tested both on a model mixture and real biological matrix of the patients urine after taking clobazam. This technique can be a confirmatory research method in addition to the clinical picture in forensic medical examination.

Examinations in relation to living persons and of corpses of persons injured in incidents involving ground wheeled vehicles remain one of the leading places in the practical activities of forensic medical experts. Over the past 35 years, the means of individual mobility have become increasingly widespread. The use of means of individual mobility naturally leads to an increase in road accidents.
To date, coverage of issues related to automobile, motorcycle, and even bicycle injuries is sufficient. However, no data on scooter trauma in the domestic forensic literature is limited, which cannot be said about the work of foreign authors.
This literature review provides some epidemiological data and information on the mechanism and type of damage in cases of injuries involving electric scooters. This kind of road incidents, including fatal ones, was statistically analyzed. Scooter trauma is characterized by its seasonality with an upward trend mainly in the warm months of the year (summer and early autumn). Young persons who directly control electric scooters are often injured. Falls in the predominant type of incident. The most traumatic parts are the head and limbs. Injuries are isolated in nature and can be both external (such as abrasions, bruises, and wounds) and internal (such as fractures). Visceral injuries in scooter injuries are extremely rare.
Elevated Bacterial STI Incidence in Canada

Rates of sexually transmitted infections (STI) have increased among gay, bisexual, and men who have sex with other men (GBM) in Canada, particularly gonorrhea and syphilis. If left untreated, these bacterial STI can cause serious sequalae among GBM such infertility and prostatitis as well as increase the risk of HIV transmission. Based on the theory of risk compensation, pre-exposure prophylaxis (PrEP) has been hypothesized as the primary contributing factor to the recent growth in bacterial STI incidence. However, findings are conflicting due to the methodological challenges of assessing how PrEP use facilitate behavioral changes for other prevention strategies such as condom use, subsequently increasing bacterial STI risk. Thus, this dissertation examined whether a) time-varying PrEP uptake affected cumulative bacterial STI incidence, b) condomless anal sex mediated the relation between PrEP uptake and bacterial STI, and c) characteristics of sexual partnerships were associated with elevated bacterial STI incidence among GBM in the era of PrEP. To answer address these research aims, this dissertation used data from the iCruise study, an online longitudinal study of GBM in Ontario, Canada. I used methods in causal inference to construct marginal structural models to evaluate the effect of PrEP uptake on rates of bacterial STI incidence and mediation models to quantify the indirect effect through condomless anal sex. In the final aim, I broaden the scope of possible mechanisms contributing to increased STI risk and adopt a descriptive epidemiology approach to generate hypotheses regarding the potential impact of partnership characteristics on STI incidence. Overall, this dissertation did not find sufficient evidence of risk compensation among iCruise participants. It demonstrates that a different mechanism (or a set of mechanisms) may better explain the observed increases in STI incidence among GBM and those on PrEP.

Virtual audits of neighborhood environments using online sources of interactive panoramic imagery, such as Google Street View, are an increasingly-common source of data for public health studies. However, most studies to date have focused on North American and Western European cities. This dissertation describes the development of a novel measure of neighborhood physical disorder applicable for use in health studies in Latin American cities. First, patterns of Google Street View image availability within Latin American cities is described. Second, virtual audits were conducted on street segments in five urban areas in the United States (New York, NY; Philadelphia, PA; Jackson, MS; San Antonio, TX; and the Rio Grande Valley, TX) and four in Latin America (Mexico City, MX; Bogota, CO; Belo Horizonte, BR; and Santiago, CL). Next, a measure of neighborhood physical disorder was adapted from this audit data, and predictors of individual perceptions of disorder by trained auditors are explored. Finally, predictive validity of the measure was assessed by examining associations between neighborhood physical disorder at the subcity level and life expectancy at birth and at age 45, comparing relationships between regions.
Estado de la cuestión de la escultura en Salamanca en el siglo XVI: nuevas atribuciones a Alonso Berruguete

Published: November 2022

Desde hace relativamente pocos años surgió la necesidad de abrir una nueva línea de estudio e investigación centradaen la escultura salmantina en madera policromada de Época Moderna, hasta entonces gran desconocida, realizadapor maestros oriundos y extranjeros que, avecindados en algún momento de su vida en la ciudad del Tormes, desarrollaronen ella y su diócesis, las limítrofes y otras más lejanas, su vida personal y laboral. Hoy, por el contrario, nos proponemosretomar la línea de estudio e investigación tradicional, es decir, la que rastreaba la presencia temporal e influencia enSalamanca de los grandes escultores castellanos del siglo XVI; en este caso Alonso Berruguete.
The Visage of a Mother’s Success
Authors: Tu Alissa
Published: November 2022

This inquiry is a personal essay about Vietnamese American youth participating in a beauty pageant and how notions of Western and Eastern beauty collide between Vietnamese American youth and their mothers. What does the beauty pageant represent for those who have been exiled from their homeland? How do ideal versions of success influence the participant’s identity or sense of self? Who is the ideal Vietnamese American beauty queen? By hypothesizing and understanding entry points that affect a mother’s perspective, Vietnamese American youth, specifically daughters, must navigate different ideals to find a sense of belonging. While being excluded from parts of American society, Vietnamese American youth are faced with trauma, values and ethics, racism and sexism while also being the personification of a mother’s success. Daughters who participate in a beauty pageant enforce a sense of community and are a symbol of hope to assimilate in America for those who have been exiled, and a participant’s success is a product of this navigation and a mother’s vicarious desires. In other words, the ideal beauty pageant queen must not only be able to uphold cultural values embedded in the beauty pageant but also their values entangled through familial relationships as well. As such, the ideal beauty pageant queen can balance both the daughter’s (Western) and the mother’s (Eastern) definition of success.
