Preliminary Data on Geochemical Characteristics of Major and Trace Elements in Typical Biominerals: From the Perspective of Human Kidney Stones

The chemical composition of biominerals is essential for understanding biomineral formation and is regarded as an attractive subject in bio-mineralogical research on human kidney stones (urinary calculi). In order to obtain more geochemically interpreted data on biogenic minerals, mineralogical compositions and major and trace element concentrations of sixty-six kidney stone samples derived from kidney stone removal surgeries were measured. Infrared spectroscopy results showed that calcium oxalate monohydrate (COM) and calcium oxalate dihydrate (COD) were the two main mineral components of kidney stones. Geochemical results indicated that major and trace element concentrations were present in the following order: Ca > Mg > Na > K > Zn > Fe > Pb > Ba > Cu > Ti > Mo > Cd > Cr. With the exception of Ca, Mg was the second-most abundant element. Zn exhibited higher concentrations relative to other trace elements, which suggests a potential substitution of calcium by metal ions with a similar charge and radius rather than by metals in kidney stone formation. Pb appeared in significantly higher concentrations than in previous studies, which indicates Pb enrichment in the environment. In order to discern multi-element relationships within kidney stones, principal component analysis was applied. Three principal components (PCs, eigenvalues >1) were extracted to explain 64.4% of the total variance. The first component exhibited positively correlated Na-Zn-Cr-Mo-Cd-Pb, while the second component exhibited more positively weighted Mg-K-Ba-Ti. Fe-Cu demonstrated a positive correlation in the third component. This study suggests that Ca exhibits a preference for uptake by oxalates during human urinary stone crystallization, while other alkali metals and alkaline earth metals precipitate with phosphate.
Hidden Markov model/Gaussian mixture models (HMM/GMM) based voice command system: A way to improve the control of remotely operated robot arm TR45

A speech control system for a didactic manipulator arm TR45 is designed as an agent in a tele-manipulator system command. Robust Hidden Markov Model (HMM) and Gaussian Mixture models (GMM) are applied in spotted words recognition system with Cepstral coefficients with energy and differentials as features. The HMM and GMM are used independently in automatic speech recognition agent to detect spotted words and recognize them. A decision block will generate the appropriate command and send it to a parallel port of the Personal Computer (PC). To implement the approach on a real-time application, a PC parallel port interface was designed to control the movement of robot motors using a wireless communication component. The user can control the movements of robot arm using a normal speech containing spotted words. Key words: Human-machine interaction, hidden Markov model, Gaussian mixture models, artificial intelligence, automatic guided vehicle, voice command, robot arm and robotics.

Evaluating online education for gifted students: Parents’ views

Due to the effects of a worldwide outbreak of COVID-19, as in many countries, students in Turkey started to have online education since March 2020. Factors such as their motivation and need for learning, and higher cognitive arousal would make it more difficult for gifted students to become away from schools. In this context, this research aimed to examine the experiences of gifted students during the online education process from their parents’ viewpoint. The data, obtained from 15 parents via telephone interviews, were analyzed by descriptive interpretive approach, one of the qualitative research methods. The validity and reliability of the data were ensured. According to the results, seven categories emerged: reflections on education, advantages, disadvantages, psychological impacts, solutions, observed emotions, and suggestions. The results were discussed in terms of gifted students’ characteristics, previous online education practices, and suggestions for future use of online education for gifted children after the pandemic period.
Long-Term Preservation of Renal Function in Septic Shock Burn Patients Requiring Renal Replacement Therapy for Acute Kidney Injury

Background. The real impact of septic shock-associated acute kidney injury (AKI) on the long-term renal outcome is still debated, and little is known about AKI-burn patients. In a cohort of burn survivors treated by continuous renal replacement therapy (CRRT) and sorbent technology (CPFA-CRRT), we investigated the long-term outcome of glomerular and tubular function. Methods. Out of 211 burn patients undergoing CRRT from 2001 to 2017, 45 survived, 40 completed the clinical follow-up (cumulative observation period 4067 months, median 84 months, IR 44-173), and 30 were alive on 31 December 2020. Besides creatinine and urine albumin, in the 19 patients treated with CPFA-CRRT, we determined the normalized GFR by 99mTc-DTPA (NRI-GFR) and studied glomerular and tubular urine protein markers. Results. At the follow-up endpoint, the median plasma creatinine and urine albumin were 0.99 (0.72–1.19) and 0.0 mg/dL (0.0–0.0), respectively. NRI-GFR was 103.0 mL/min (93.4–115). Four patients were diabetic, and 22/30 presented at least one risk factor for chronic disease (hypertension, dyslipidemia, and overweight). Proteinuria decreased over time, from 0.47 g/day (0.42–0.52) at 6 months to 0.134 g/day (0.09–0.17) at follow-up endpoint. Proteinuria positively correlated with the peak of plasma creatinine (r 0.6953, p 0.006) and the number of CRRT days (r 0.5650, p 0.035) during AKI course, and negatively with NRI–GFR (r −0.5545, p 0.049). In seven patients, urine protein profile showed a significant increase of glomerular marker albumin and glomerular/tubular index. Conclusions. Burn patients who experienced septic shock and AKI treated with CRRT had a long-term expectation of preserved renal function. However, these patients were more predisposed to microalbuminuria, diabetes, and the presence of risk factors for intercurrent comorbidities and chronic renal disease.
Self-management of daily life tasks in diploma-track youth with disabilities

Abstract Purpose Youth with disabilities who graduate with a regular high school diploma often continue to have difficulties in their daily functioning that ultimately impact adulthood outcomes. To better understand these functional difficulties and determine how best to address them, it is important to distinguish deficits in discrete skills from difficulty organizing skills to self-manage complex tasks associated with adult roles. The purpose of this study was to explore the extent to which challenges in social, executive function and behavior management factors relate to these two aspects of daily functioning. Methods This is a secondary analysis of the National Longitudinal Transition Study 2 funded by the United States Department of Education. The direct and indirect associations between youth underlying factors and self-management of daily life tasks (SMDLT) versus discrete functional skills were modelled using structural equation modelling. Results A model incorporating social skills, communication, and behavior regulation explained 55% of the variance in SMDLT. In contrast, the model predicting discrete functional skills had fewer significant associations and described less variance (37%) in the outcome. Conclusions Findings suggest that using measures of SMDLT and designing targeted interventions for SMDLT might help improve participation in independent living and productivity for diploma-track youth with disabilities. Implications for rehabilitation Successful transition from high school to adult roles requires the ability to self-manage the daily life tasks required for those roles, such as employment, post-secondary education, and independent living. The ability to self-manage daily tasks is distinct from mastery of discrete functional skills and should be assessed with measures that uniquely examine this domain. Social and communication skills, executive functioning, and behavioral regulation, are important contributors to the ability to self-manage life tasks for diploma-track youth with disabilities and should be incorporated into multifaceted interventions. Interventions to improve self-management of tasks should include teaching strategies and practice coordinating underlying skills in flexible ways that meet the varying demands of tasks and diverse environments.
Application of Bi-CGSTAB to waveguide discontinuity problems

Scattering at a waveguide end facet or other waveguide discontinuities can be calculated by an iterative method together with rational approximations to the related square root operators. Previous work uses the classical Neumann series as the iteration scheme. We demonstrate that the method can be significantly improved if bi-conjugate gradient stabilized is used instead.
DIT - University of Trento Engineering Service-Oriented Systems: Modeling, Discovery and Quality

Service-oriented computing changes the face of modern software by decomposing its application logic. Now business systems can be assembled from loosely-coupled service components developed by various organizations and spread across the world. Service-Oriented Systems (SOSs) incorporate services running on different platforms and hosted by service providers outside of enterprise boundaries. This conceptually new approach to software development poses multiple questions to software engineers. The behaviour of incorporated web services may vary over time, as well as business rules underlying the system. The SOSs should be reactive to any changes in external services, such as service failures or performance decrease. Therefore, discovery of relevant service components and selection of business partners that guarantee good Quality of Service (QoS) are among the prime issues. In this thesis we investigate the problem of developing dependable SOSs from available web services. Firstly, we introduce an approach for conceptual modeling of SOSs, which prescribes a sequence of activities for transforming abstract business processes into service-based workflows. The approach is an extension of the Eriksson-Penker business process modeling framework. Service discovery, risk analysis and QoS-aware selection are parts of the design process. A case study is given to analyze the use of the proposed modeling method. Secondly, we investigate techniques for efficient web service discovery. Our work is primarily concerned with the problem of finding and select-
Antibacterial and cellular behavior of PLA-based bacitracin and zataria multiflora nanofibers produced by electrospinning method

Abstract In this study, poly(lactic-acid) (PLA) polymer-based nanofiber (NF) was obtained by the electrospinning method. Antioxidant Zataria Multiflora (ZM, essential oil extract) and antibiotic effective bacitracin (BAC) materials were added to 8% PLA. ZM essential oil was extracted with Rotary and antioxidant components were investigated using GC-MS. While carvacrol constitutes 50% as the main component of ZM, it was seen as 48.06% carvacrol and 25.47% thymol as a content area. It was analyzed that ZM has a total antioxidant rate of 99.87% with 20 components. In antibacterial tests, PLA/BAC/ZM NF showed the best inhibition growth on all microorganisms (Escherichia coli, Staphylococcus aureus, Bacillus cereus, Staphylococcus epidermidis, Bacillus subtilis). In cell XTT cytotoxicity tests, it was observed that the PLA/BAC/ZM NF used in adhesion and 4′,6-diamidino-2-phenylindole (DAPI) results showed very good adhesion to cells. GRAPHICAL ABSTRACT
Engineering the shape memory parameters of graphene/polymer nanocomposites through atomistic simulations: On the effect of nanofiller surface treatment

This paper aims to comprehend the mechanisms underlying the shape memory behavior of polylactic acid infused with graphene functionalized by four groups of –OH, –CH3, –NH2, and tethered polymer layer. Applying molecular dynamics simulation, it is revealed that the graphene surface treatment enhances the shape fixity ratio of nanocomposites monotonically by increasing the physical cross-linking points within the polymer matrix. The improvement would be even more pronounced by increasing the coverage degree of small functional groups and grafting density of the covalently bonded polymer chains. Monitoring the key parameters illustrates that contrary to the OH groups, which improve the shape recovery value, the other functional groups degrade it by prohibiting the polymer chains mobility. Attempts to explore the governing mechanism demonstrate that shape fixity is improved when the difference between the potential energy variations in the loading and unloading stages increases. Interestingly, shape recovery is only under the influence of conformational entropy, and it is not affected by the potential energy. As such, we also probe variations of the radius of gyration during the recovery stage to address the role of different functionalization procedures on the reported shape recovery parameter.
Slip resistance of the shoe-floor interface under biomechanically-relevant conditions

Slip resistance measurements are used by industry, shoe/floor manufacturers, and the legal profession as a criterion for determining slip potentials of various environments. Whilst static coefficients of friction (COF) of a shoe-floor interface have been used traditionally, dynamic COF(DCOF) measures have been shown to be more relevant to the biomechanics of slips and falls. Recently, new devices have become available that better incorporate the biomechanics of foot movement into DCOF measurement. The purpose of this study was to investigate the effects of environmental and biomechanical factors of the shoe-floor interface on DCOF measures using a new slip resistance testing device. The environmental factors chosen were shoe material, floor type, and contaminant. The biomechanical factors were heel velocity, vertical force, and shoe angle. The results showed that of the biomechanical factors, heel velocity had largest effects on the DCOF. However, contaminant condition was an important interaction. Increa.
Study on inducer and impeller of a centrifugal pump for a rocket engine turbopump

A hydraulic performance test is conducted for a fuel pump of a liquid rocket engine turbopump. The pump driven by an electric motor is tested in a water environment. Experimental results indicate that the inducer has a negligible effect on the head and efficiency of the pump but a significant effect on the cavitation performance. Additionally, an autonomous inducer test is carried out to investigate the effect of the inducer on the pump performance in more detail, and it is found out that the pump reaches a critical cavitation point when the inducer head is dropped by 55%. A reduction of required net positive suction head of the centrifugal pump by attachment of an inducer is also calculated considering the flow interference between the inducer and the centrifugal impeller, and it is found that the calculation shows a reasonable agreement with the test.
Barriers for Early Detection of Breast Cancer among South Indian Women

Background: Breast cancer is one of the most common neoplasms in women across the world. Early diagnosis of breast cancer results in reduced morbidity, mortality, and improved quality of life. Objective: This study was conducted to identify the barriers among Indian women diagnosed with breast cancer in an advanced stage. Methods: A cross-sectional descriptive survey was conducted in a tertiary care teaching hospital, Southern India, among breast cancer patients. A total of 202 women with breast cancer (Stage 3 and 4) were recruited based on the predefined inclusion and exclusion criteria. The data were collected using a demographic proforma and barrier checklist and analyzed using SPSS 16.0 version. Results: The mean age of the women was 51.5 ± 10.7 years. The majority of them were Hindu (87.6%), housewives (69.8%), with primary education (39.6%). The women have cited several barriers including financial (54.5%), lack of knowledge about breast cancer (49.5%), frightened about diagnostic test result (56.9%), afraid of anticipated surgery (54.5%), and the dearth of accessibility to health resources (52%). Conclusions: The presence of barriers in early diagnosis of breast cancer occurs in various contexts and should be recognized and minimized by all health-care providers to reduce the associated health-care cost, morbidity, and mortality.
From Siliciclastic to Bioclastic Deposits in the Gulf of Naples: New Highlights from Offshore Ischia and Procida–Pozzuoli Based on Sedimentological and Seismo-Stratigraphic Data

This study discusses the siliciclastic to bioclastic deposits (in particular, the rhodolith deposits) in the Gulf of Naples based on sedimentological and seismo-stratigraphic data. The selected areas are offshore Ischia Island (offshore Casamicciola, Ischia Channel), where a dense network of sea-bottom samples has been collected, coupled with Sparker Multi-tip seismic lines, and offshore Procida–Pozzuoli (Procida Channel), where sea-bottom samples are available, in addition to Sparker seismic profiles. The basic methods applied in this research include sedimentological analysis, processing sedimentological data, and assessing seismo-stratigraphic criteria and techniques. In the Gulf of Naples, and particularly offshore Ischia, bioclastic sedimentation has been controlled by seafloor topography coupled with the oceanographic setting. Wide seismo-stratigraphic units include the bioclastic deposits in their uppermost part. Offshore Procida–Pozzuoli, siliciclastic deposits appear to prevail, coupled with pyroclastic units, and no significant bioclastic or rhodolith deposits have been outlined based on sedimentological and seismo-stratigraphic data. The occurrence of mixed siliciclastic–carbonate depositional systems is highlighted in this section of the Gulf of Naples based on the obtained results, which can be compared with similar systems recognized in the central Tyrrhenian Sea (Pontine Islands).
EXPERIMENTAL STUDY OF GROUND ENERGY SYSTEMS IN MELBOURNE, AUSTRALIA

Ground energy systems use the ground as a heat source or sink to heat and cool buildings. Because the ground temperature is more stable than the ambient air, ground energy systems can be more efficient than conventional heating and cooling systems. Ground energy systems typically comprise a ground heat exchanger (GHE) connected to a building’s heating and cooling system via a heat pump. The GHE is usually a closed loop of pipe embedded in the ground. Fluid circulates through the embedded pipes to exchange heat between the ground and the building. A research facility has been built at the University of Melbourne’s Parkville campus to experimentally study the effects of GHE configuration on ground energy system performance and investigate the potential to improve existing design techniques. This paper provides an introduction to ground energy systems and describes the experimental set-up.
Accelerated evolution of the system support paradigm

A number of trends, including growing prime system complexity, the more widespread use of COTS equipment, an inclination to extended contractor support, and the increasing importance of global diagnostic coverage, all portend changes in the current system support paradigm. These changes will affect support acquisition, development, design and operational practice insofar as they relate to generic diagnostic functions and their realization using modern enabling technologies. Beneficial changes can be accelerated through the coordinated insertion of these technologies within the framework of a systems engineering process.
When Non-Suicidal Self-Injury Predicts Non-Suicidal Self-Injury and Poor Sleep—Results from a Larger Cross-Sectional and Quasi-Longitudinal Study

Poor sleep is associated with a higher risk of non-suicidal self-injury (NSSI) as a proxy of unfavorable emotion regulation. In the present study, we tested the hypothesis that past non-suicidal self-injury was associated with current non-suicidal self-injury and with current subjective sleep patterns. To this end, a larger sample of young adults were assessed. A total of 2374 adults (mean age: 27.58 years; 39.6% females) completed a series of self-rating questionnaires covering sociodemographic information, past and current NSSIs, suicide attempts, and current sleep patterns, including experiencing nightmares. Past NSSIs predicted current NSSIs. Current sleep patterns had a modest impact on the association between past and current NSSIs. Compared to male participants, female participants did not report more sleep complaints or more current NSSIs, but more past NSSIs. Past NSSIs predicted the occurrences of nightmares and suicide attempts. The best predictor of current NSSI was the remembered past NSSI, while current poor sleep was only modestly associated with current NSSI. Further indicators of current NSSI and poor sleep were suicide attempts and nightmares within the last six months. Overall, it appears that poor emotion regulation should be considered as underlying factor to trigger and maintain non-suicidal self-injury-related behavior and poor sleep. Further, unlike previous studies, which focused on the possible influence of sleep patterns on NSSIs, the aim of the present study paradigm was to investigate NSSIs on sleep patterns.
