Evaluating the role of a fully automated SARS-CoV-2 antigen ECLIA immunoassay in the management of the SARS COV 2 pandemic on general population
Authors: Carta Mariarosa , Pascarella Michela , Cappelletti Anna , Rassu Mario , Giavarina Davide
Published: October 2022

Objectives

Chemiluminescence immunoassay (CLIA) automated assays (fourth-generation antigen test) for SARS-CoV-2 detection are promising because of their analytical productivity, but have lower sensitivity and specificity than rt-PCR assays. The authors of this paper evaluated a recent immunoassay implemented on Siemens Atellica IM, investigating how much this could affect the actual feasibility of this diagnostic during the pandemic.

Methods

From the three-day routine 134 positive and 241 negative swab samples by rt-PCR test were evaluated, selected as 1/3 positive – 2/3 negative.

Results

Using rt-PCR as gold standard, the specificity of immunoassay was 96.7%, while sensitivity was 68.0%. Sensitivity is inversely proportional to the viral load: 100% for cycles threshold (CT) values from 14 to 29, 95% until 30 CT, then 85, 74, 72, 68%, for 31–35 CT respectively.

Conclusions

Our study confirms the reliability of the fourth-generation antigen assay in recognizing negative samples. Conversely, sensitivity appears to be less reliable (68.0%) than reported in the literature. This could be due to a non-randomized study group: many swab samples were taken from patients with expected low viral load (hospitalized for COVID for more than 10–12 days or asymptomatic patients for epidemiological surveillance). The strong correlation of sensitivity and viral load could prove significant to track the infectiousness of infected people, as previous studies reported that a viral load of at least 10E6 copies of RNA/mL, corresponding to 25 CT, is the threshold of transmission of the disease.

Published: October 2022

Objectives

Meteorin-like peptide (Metrnl), the newly discovered adipokines involves in glucose and lipid metabolism and energy homeostasis. The aim of the present study was to explore the potential predictors of Metrnl by emphasizing the Irisin, glycemic indices, and lipid profile biomarkers in type 2 diabetic patients.

Methods

This cross-sectional study was carried out on 32 obese types 2 diabetic patients, 31 healthy obese, and 30 healthy normal weight people between August 2020 and March 2021. Serum Metrnl and Irisin, fasting blood glucose (FBS), fasting insulin (FI), fasting insulin (FI), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), HbA1c and eAG levels were measured in a standard manner. To assay insulin resistance and insulin sensitivity, the homeostatic model assessment insulin resistance (HOMA‐IR) and quantitative check index (QUICKI) model were used. Quantile regression analysis with the backward elimination method was used to explore predictors. The significant level was defined as p<0.05.

Results

Between variables entered into the model, only the group item showed to be the main predictor of Metrnl in type 2 diabetic patients. Besides, the serum level of Irisin was lower in diabetic patients, and a significant difference was detected between obese diabetic patients and the normal weight group (p=0.024).

Conclusions

Given the multi-causality of diabetes and also the possible therapeutic role of Metrnl in the management of type 2 diabetic patients’ abnormalities, designing future studies are needed to discover other predictors of Metrnl and the related mechanisms of Metrnl in the management of diabetes.
The relationship between humor and women’s body image concerns and eating behaviors
Authors: Fasoli Fabio , Ogden Jane , Johnson Susie
Published: October 2022

Humor is considered a coping strategy that is associated with well-being and positive self-esteem. The role of humor in relation to body image and eating behaviors has rarely been investigated. This cross-sectional study (n = 216) examined the relationship between general coping humor and humor styles targeting the self, namely self-enhancing and self-defeating humor, and body image and eating behaviors. Results showed that adaptive self-enhancing humor was associated with body appreciation and compassion, whilst maladaptive self-defeating humor was related to body criticism, drive for thinness, and emotional eating. General coping humor played almost no role. We also examined humor clusters and found that body appreciation and body kindness were higher in self-enhancers than self-defeaters and higher in humor endorsers than humor deniers. Further, self-defeaters reported more body criticism and emotional eating than self-enhancers, and emotional eating was higher in humor deniers than humor endorsers. This study shows that humor referring to the self is key in the understanding of body image and eating behaviors. Whilst the use of self-enhancing humor can have positive effects on body image, self-defeating humor can play a detrimental role.
Joining of titanium—copper TA2/T2 bimetallic sheet by double side laser—TIG welding
Authors: Yu DeShui , Zhang Yan , Zhou JianPing , Sun DaQian , Li HongMei
Published: October 2022

In this paper, laser—tungsten inert gas (TIG) hybrid welding of TA2 titanium alloy and T2 copper alloy dissimilar joint has been performed using BCuP-2 wire as filler metal. A new welding process for TA2/T2 joining was introduced on the basis of the controlling the formation of Ti–Cu intermetallics in the joint. One process was two-pass welding involving creation of a joint with one laser weld and one TIG weld separated by remaining unmelted TA2/T2 interface. The influence of the hybrid welding process on the microstructure of the interfacial intermetallic compounds, and tensile strength of joints was investigated. The grain size of the TA2 fusion weld became larger after welding, forming acicular α martensite structure. The metallurgical combination between TIG weld and T2 base metal was good, and the TIG weld was mainly composed of α-Cu solid solution and a fine layered structure. However, a reaction layer containing α-Cu + α-Ti with an average width of about 30 μm was formed at the interface between the TIG weld and TA2 base metal, and fracture occurred along the TA2 weld and the interface of the reaction layer during tensile testing. A large number of Ti–Cu brittle compounds were avoided in joints, and the maximum tensile strength reached 610 MPa.
L2 textbook input and L2 written production: a case of Korean locative postposition–verb construction
Authors: Jung Boo Kyung , Shin Gyu-Ho
Published: October 2022

This study investigates how L2 learners of Korean in foreign language-learning environments manifest the target knowledge as a function of various factors surrounding the learners (e.g., L2 textbook input, language-specific properties, general language-use experience in class), specifically concerning the learners’ written production of the postposition–verb pair in a locative postposition–verb construction. For this purpose, we analyze two textbook types and learner writing from two L1 groups, focusing on postposition/verb use, Type–Token Ratio, and keyness. We find some meaningful relationships, but also inconsistencies, between L2 textbook input and L2 written production regarding this construction. We discuss implications of the findings with respect to how L2 knowledge is shaped at the interface of L2-textbook characteristics, language-specific properties involving the target knowledge, learners’ L1, and general language-use experience in class. Based on the results, we also discuss pedagogical implications, with emphasis on (methods and technologies of) utilizing the existing corpora for instructional purposes.
Speaking proficiency development in EFL classrooms: measuring the differential effect of TBLT and PPP teaching approaches
Authors: Harris Justin , Leeming Paul
Published: October 2022

This paper outlines a classroom-based study on the timing of explicit language instruction. It also provides an alternative to the CALF (Complexity Accuracy Lexis Fluency) framework for analyzing learner language, which may not always be appropriate for EFL contexts. Two groups of learners, assigned to either a TBLT or a PPP condition, completed a speaking task. A follow-up task was given three months later, but with no explicit language focus for either group. Data from these interactions were analyzed for use of target grammar structures and overall speaking proficiency. Results suggest that explicit introduction of language through PPP benefits immediate task performance, but that ultimately post-task focus on language through TBLT leads to greater language development. The framework for analysis was effective in showing differences in performance between the groups in this context.

Published: October 2022

“Placenta Accreta Spectrum” (PAS) describes abnormal placental adherence to the uterine wall without spontaneous separation at delivery. Though relatively rare, PAS presents a particular challenge to anesthesiologists, as it is associated with massive peripartum hemorrhage and high maternal morbidity and mortality. Standardized evidence-based PAS management strategies are currently evolving and emphasize: “PAS centers of excellence”, multidisciplinary teams, novel diagnostics/pharmaceuticals (especially regarding hemostasis, hemostatic agents, point-of-care diagnostics), and novel operative/interventional approaches (expectant management, balloon occlusion, embolization). Though available data are heterogeneous, these developments affect anesthetic management and must be considered in planed anesthetic approaches. This two-part review provides a critical overview of the current evidence and offers structured evidence-based recommendations to help anesthesiologists improve outcomes for women with PAS. This first part discusses PAS management in centers of excellence, multidisciplinary care team, anesthetic approach and monitoring, surgical approaches, patient safety checklists, temperature management, interventional radiology, postoperative care and pain therapy. The diagnosis and treatment of hemostatic disturbances and preoperative prepartum anemia, blood loss, transfusion management and postpartum venous thromboembolism will be addressed in the second part of this series.
Head and dependent marking and dependency length in possessive noun phrases: a typological study of morphological and syntactic complexity
Authors: Sinnemäki Kaius , Haakana Viljami
Published: October 2022

The interaction of morphosyntactic features has been of great interest in research on linguistic complexity. In this paper we approach such interactions in possessive noun phrases. First, we study the interaction of head marking and dependent marking in this domain with typological feature data and with multilingual corpus data. The data suggest that there is a clear inverse relationship between head and dependent marking in possessive noun phrases in terms of complexity. The result points to evidence on complexity trade-offs and to productive integration of typological and corpus-based approaches. Second, we explore whether zero versus overt morphological marking as a measure of morphological complexity affects dependency length as a measure of syntactic complexity. Data from multilingual corpora suggest that there is no cross-linguistic trend between these measures in possessive noun phrases.
Linguistic complexity in second language acquisition
Authors: Kuiken Folkert
Published: October 2022

Since the 1990s linguistic complexity has become an important issue in second language acquisition (SLA) research and teaching: second language (L2) learners want to know how well they are progressing, while teachers and researchers are interested to find out which grade of complexity can be associated with a particular proficiency level. After a short sketch of the background to the construct of complexity, the paper presents an overview of how complexity is measured in SLA, how it is related to other constructs of language proficiency (in particular accuracy and fluency), and by which factors complexity may be affected: these concern both internal linguistic factors and external factors, like task-related features and type of instruction. The paper concludes with directions for future research, focusing on the need for non-redundant, valid and reliable measures, more developmental measures, a broader scope of complexity, combined cross-linguistic and longitudinal research, and more research in instructional practice.
A short overview of radioactivity measurement studies in Uzbekistan
Authors: Khasanov Shakhboz , Safarov Akmal , Tukhtaev Ulugbek , Mavlonov Temurbek
Published: October 2022

Natural radioactivity is a public health issue that affects people all around the world. Environmental radioactivity accounts for approximately 87% of the radiation dose received by human beings. The primary external source of irradiation to the human body is gamma radiation emitted by naturally occurring radioisotopes such as 40K and radionuclides from the 232Th and 238U families, as well as their decay products, which exist at trace amounts in all ground formations. The establishment of baseline data for environmental radiological studies is of great importance for the assessment of environmental radiological levels in Uzbekistan and related studies on human health risks. The current study aimed to describe the research state of the art on natural radioactivity in Uzbekistan with emphasis on results obtained during the last 20 years. NaI (Tl) and High Purity Germanium HPGe detectors were employed in most conducted studies. The results showed that data for natural radionuclide activity were below international standards in all but a few areas. The research results of this paper can play a good guidance and reference role in the planning of such research in the future.

Published: October 2022

The increasing need of environment protection and preservation has been stimulating road agencies to progressively adopt sustainable technologies for the design, construction, and maintenance of their assets, with the consequent increasing use of recycled materials, industrial by-products, and wastes. In such a context, the experimental investigation presented in this paper moved from the idea of synergistically combining the use of bottom ashes originating from incineration of municipal solid waste (MSW) and crumb rubber from end-of-life tires. The performance-related properties of rubberized asphalt mixtures containing MSW bottom ashes in partial substitution of natural aggregates were evaluated by means of laboratory tests focused on the determination of workability, viscoelastic characteristics, anti-rutting potential, and resistance to crack propagation. Tests were carried out by considering an ash-amended rubberized asphalt mixture and, for comparison purposes, a standard gap-graded rubberized mixture (GGRM). Obtained results indicate that the rubberized mixture containing bottom ashes exhibited lower workability (16 % decrease in k parameter), reduced stiffness (decrease of dynamic modulus at 20°C of approximately 40 % and 60 % at 0.1 Hz and 10 Hz, respectively), and decreased anti-rutting potential (17 % decrease in flow number values) with respect to the standard GGRM. Conversely, the addition of bottom ashes was found to provide beneficial effects in terms of resistance to crack propagation (with fracture toughness values five times larger than those of the reference mixture). These outcomes suggest that the use of MSW bottom ashes must be carefully considered because environmental benefits may be counterbalanced by lower performance.

Published: October 2022

One-quarter of gay, bisexual, and other men who have sex with men (GBMSM) with diagnosed HIV are not engaged in HIV care. Between 2018 and 2019, 50 GBMSM completed qualitative interviews 3 months after receiving an HIV-positive result. Interviews explored barriers to and facilitators of engagement and retention in HIV testing and care. Thematic analysis revealed five major themes: (1) reason for HIV testing (e.g., self-testing), (2) linkage to care (e.g., appointment/logistic issues and social support as encouragement), (3) barriers to engagement in care (e.g., financial burden, competing priorities, and fear/stigma), (4) facilitators of engagement (e.g., financial assistance, patient-provider relationships, auxiliary support services, and health agency), and (5) PrEP as a missed prevention opportunity. Addressing individual-, social-, and policy-level barriers could improve GBMSM's engagement in HIV care. Further, capitalizing on GBMSM's health agency through partnerships with local agencies and fostering better patient-provider relationships could optimize HIV care continuity.

Published: October 2022

Long-acting injectable pre-exposure prophylaxis (LAI-PrEP) was recently approved for HIV prevention as an alternative to daily oral PrEP. We explored preferences and attitudes toward LAI-PrEP among Black, Hispanic/Latino, and White gay, bisexual, and other men who have sex with men (GBM) using focus groups (n = 13) and in-depth interviews (n = 17). Participants expressed differing levels of interest in LAI-PrEP. While important benefits of LAI-PrEP included convenience, provider-facilitated PrEP discussion, and expansion of PrEP options, participants raised concerns about treatment efficacy and side effects, discomfort with needles/injections, cost, and frequency of clinic visits. Our findings highlight ongoing challenges with accessing HIV-prevention tools and provide guidance for developing strategies to enhance LAI-PrEP uptake among GBM.

Published: October 2022

The main aim of this article is to compare the prevalence of four forms of physically self-destructive behavior in the offspring of parents with borderline personality disorder (BPD) and compare them to the offspring of parents with other personality disorders (OPD). At the 4- and 6-year waves in a prospective study of the long-term course of BPD, participants were asked to report on the self-destructive behaviors of their children using the Childhood Self-Destructiveness Scale. A total of 68 parents were interviewed regarding 131 children, 104 of whom were offspring of parents with BPD (n = 55) and 27 were offspring of parents with OPD (n = 13). BPD parents reported significantly more self-injury and substance abuse in their children than OPD parents. The results from this study suggest that both direct and indirect forms of self-destructive behavior are both more common and quite specific for the children of parents with BPD.
What If I Feel Rejected? Borderline Personality, Pathological Narcissism, and Social Rejection in Daily Life
Authors: Di Pierro Rossella , Amelio Sara , Macca Martina , Madeddu Fabio , Di Sarno Marco
Published: October 2022

The authors investigate whether and how borderline and pathological narcissistic traits differ in their associations with trait and state rejection sensitivity, and with affective reactions to experiences of social rejection occurring in daily life. Community adults (N = 189) completed baseline measures of rejection sensitivity, borderline personality, and pathological narcissism, and daily measures of perceived social rejection and affective states for 7 days. Vulnerable narcissism was the main driver of negative anticipated emotions for social rejection. Borderline personality made people prone to experiencing social rejection in daily life. Moreover, borderline personality traits predicted greater self-directed aggressive impulses when experiencing social rejection. Grandiose narcissism showed only a negative association with anticipatory anxiety for rejection. These findings highlight that sensitivity to social rejection is crucial in both borderline personality and pathological narcissism.
Relations Between Anxiety Sensitivity and Attachment in Outpatients With Borderline Personality Disorder
Authors: Doyle Jessie N. , Watt Margo C. , Cohen Jacqueline N. , Couture Marie-Eve , Smith MacGillivray M.
Published: October 2022

Borderline personality disorder (BPD) is characterized by dysregulated emotion, interpersonal relationships, and impulsivity, and is putatively linked to a known transdiagnostic risk factor, anxiety sensitivity (AS). AS is a dispositional fear of the physical, cognitive, and/or social consequences of arousal-related somatic sensations. Gratz et al. (2008) demonstrated significantly higher AS in outpatients with BPD and a predictive value of AS over and above emotion dysregulation and impulsivity. The present study sought to extend these findings with a larger sample of outpatients with BPD by investigating predictive value of AS dimensions; relations between AS and attachment style; and impact of BPD treatment on AS. Participants completed measures at three time points: pretreatment and 6 and 12 months posttreatment. AS social was the best predictor; attachment anxiety correlated positively with AS global and AS physical. AS levels significantly decreased from pretreatment to 6 months posttreatment. Clinical implications discussed include targeting AS in BPD treatment.
Discrimination Without Intoxication: The Role of Controlled Processes in the Promotion of Racial Bias After Viewing Alcohol-Related Cues
Authors: Petzel Zachary W. , Noel Jeffrey G. , Casad Bettina J.
Published: October 2022

Viewing alcohol-related cues (e.g., advertisements) is known to promote expressions of racial bias and aggression through the temporary promotion of reflexive or impulsive responding. However, this increased automaticity may be inhibited by thoughtful control of behavior. We examined the role of controlled processes in the suppression of racial bias following alcohol cue exposure across two experiments. Experiment 1 (N = 125) indicated reduced control of behavior promoted greater expressions of racial bias after viewing alcohol-related cues. Experiment 2 (N = 71) replicated these effects, suggesting individuals with lower neural indices of control, indexed by reduced amplitudes of the error-related negativity (ERN), similarly express greater racial bias after viewing alcohol-related cues. These findings replicate previous work suggesting alcohol-related cues promote impulsivity and application of negative racial stereotypes. Yet, whether this automaticity manifests into behavioral expressions of racial bias depends on the availability to engage self-control to inhibit these socially undesirable responses.
Individual learning strategies and other characteristics of e-learning in the first phase of online learning during the COVID-19 pandemic
Authors:   Uniwersytet Jagielloński, Poland, Smoter Katarzyna
Published: October 2022

One aspect of university governance during the Covid - 19 pandemic was the introduction of compulsory distance learning. This set-up required significant modifications in the organisation of the teaching-learning process, becoming an area of reflection in the field of academic didactics. The main addressees of the described educational change were female and male students - entities who chose different paths to achieve their learning goals. The analysis subject of this article is to identify such characteristics as, inter alia, their learning strategies, ways of evaluating online classes or emotions experienced in a learning situation. The pilot studies were carried out in the first phase of introducing remote university teaching, and were done using a unique questionnaire. The theoretical basis of the research was the learning theory of adults, described by M. Knowles, co-creators of the teaching-learning process, selecting methods of action to specific problems. In this article we refer to the description of the strategy (individual learning) according to R. Arends (1998), as well as other issues related to remote university learning, i.e. evaluation of one's own study process, satisfaction with studying and emotions evoked by the necessity to learn remotely. Referring to the research results, the most frequently chosen strategies were those around working with 'written text': highlighting the most important information, creating notes or adding comments in the text. On the other hand, online classes were often of low value for the students. The obtained results also indicate the predominance of negative feelings and states related to anxiety, anger or disappointment with the remote organisation of university work.
PhotoVoice (PV) as an educational research method - considering the possibilities of online work in the fourth grade of primary school. Challenges and solutions.
Authors:   Uniwersytet Kardynała Stefana Wyszyńskiego w Warszawie, Poland, Zioło-Pużuk Karolina
Published: October 2022

The aim of this article is to find an answer to the question of whether the PhotoVoice method can be used in online educational research conducted with children aged 10-11. The author describes the aims and methodology of PhotoVoice. The paper also presents the ethical and organisational challenges faced by researchers wishing to use PhotoVoice in educational settings. The conducted pilot study did not provide an unequivocal answer to the research question, but indicated the directions in which further research should be conducted. It showed how the PV procedure should be changed, while maintaining the main objectives of the method, enabling its implementation in work with children in the fourth grade of primary school. The changes should include greater involvement and empowerment of students, conducting a mini-project preceding the actual project, and limiting the role of the teacher to participation in the final stage, i.e. the presentation of photographic work to decision-makers. At the same time the pilot project made it possible to conclude that the involvement of students in the project, in-depth reflection on photographs and discussions and motivation to propose changes in the immediate educational environment pose additional challenges if the project is conducted online.
Analysis of physical dimensions in tsunami disaster resilience in Tanjung Lesung Special Economic Zone, Indonesia
Authors: Ristya Yoanna , Hasibuan Hayati Sari , Lubis Rissalwan Habdy
Published: October 2022

The Tanjung Lesung Special Economic Zone (SEZ) is a tourism area close to faults and active volcanoes. This location causes the Tanjung Lesung SEZ to have a high tsunami threat. In 2018, this area became an area affected by the Sunda Strait tsunami, which caused various losses, including casualties. This study aimed to examine the physical characteristics of the Tanjung Lesung coastal area, which has a tsunami threat. The physical characteristics in the research are elements that can affect the resilience of the tsunami disaster on the Tanjung Lesung coast. These include land use, topography, evacuation routes, and settlement conditions. This study used primary and secondary data obtained through government agencies and a field survey in 2021. The overlay analysis method on GIS was used to provide a spatial explanation of the physical characteristics of tsunami-prone areas. The study results showed that shrubs, a slope of 2-15%, and a height of 5-25 m above sea level dominate the area with the category of dangerous and very dangerous levels. The results also explained that there are settlements with wooden wall structures and cement floors located in very dangerous areas (with an area of 32.06  ha) and dangerous areas (with an area of 11.62 ha). Based on the analysis, there are three distinct categories in the research area. All three categories require coastal boundary planning that considers the tsunami threat to increase disaster resilience. The research results can be used to increase disaster resilience or spatial planning in coastal areas.
Disposal slope design based on low-plasticity rock’s shear strength in coal mining activities
Authors: Hasan Harjuni , Oktaviani Revia , Trides Tommy , Sinaga Dionisyus Fransiskus
Published: October 2022

Slope stability is the primary factor in designing a stable slope. The strength of the disposal slope relies on the characteristic of the dump materials. The rock shear strength denotes rock ability to withstand the burden, both constant and dynamic load. The weakest material used as a reference in designing the disposal slope is siltstone in Pulaubalang formation (location-04). The safety value in Location 04 and 02 tend to drop quickly as the inclination increase, while the safety in location 01 and 03 tend to fall slowly. This indicates that rocks with a lower plasticity index tend to be stronger in steeper slope conditions. The slope geometry was designed to be 10, 15, 20, and 25 meters high with a slope angle of 10o, 15o, 20o, 25o, 30o, 35o, 40o, 45o, 50o, 55o, and 60o. The slope geometry is considered stable and safe. However, this study suggests that the most effective slope design is the slope with 25 meters high, overall slope of 25,3o; the single slope of 35o; berm width 4,66 meters, bench height of 5 meters, with the safety factor value of 4.30 (SF= 4.30).

Published: October 2022

Monitoring shoreline changes is important in detecting abrasion and accretion in coastal areas. This study aimed to determine the level of shoreline change caused by abrasion and accretion and estimate the change rate. The study area covers coastal areas in ten Districts in Biak Numfor Regency (only on Biak Island). Six Landsat image datasets (1997, 2002, 2007, 2013, 2018, and 2022) were used to determine the coastline. Shoreline changes were analysed using DSAS software. The results of digitising the shoreline show a change in the length of the shoreline during the six data periods. Based on NSM and EPR for the last ten years (2013-2022), the average shoreline changes due to abrasion range from -6.65 to -13.16 m with an abrasion rate of -0.76 to -1.50 m/year. Meanwhile, the average shoreline changes due to accretion ranged from 4.64 to 8.45 m with an accretion rate of 0.53 m/year to 0.96 m/year. Changes in shoreline based on the rate of abrasion and accretion vary greatly in each district along the coastal area of Biak Numfor Regency, depending on the EPR value of each transect. Spatially, high abrasion and very high abrasion are widely distributed in Oridek, Biak Utara, Swandiwe, and Warsa Districts. Medium and high accretion were found in Yawosi, Bindifuar, and Oridek Districts. Because there has been a change in the coastline due to abrasion, planning efforts to mitigate coastal areas are very necessary.

Nowadays, halting greenhouse gasses (GHG) emission is the world's major concern to mitigate global climate change. In oil palm cultivated tropical peatland, GHG emission is primarily constituted of CO2 flux emitted from aerobic heterotrophic respiration (Rh), the natural degradation process of organic material in an oxidative environment. By coupling descriptive and predictive statistical approaches, this study attempt to gain an in-depth understanding of the effects of zeolite rates and incubation time on CO2 emission that came from aerobic Rh in peat, as well as their decomposition process. This study found that zeolite amelioration up to 30% of the peat at field capacity and starting from the first month of observation (month-1) significantly restricted peat Rh, denoted by a reduced amount of observed CO2 flux (0.021 and 0.019-0.012 mg m-2 sec-1, respectively). Both factors and several soil variables exhibited some non-linear relationships with Rh at different magnitudes and importance, showing the limitation of the traditional linear-based approach to interpreting their complex interrelationships, as well as predicting CO2 flux. This study highlights the vital role of a polynomial (GAM) and artificial intelligence (Cubist and GBM) -based pedotransfer models in improving our understanding regarding the dynamic of the peat decomposition process as affected by zeolite amendment.

Published: October 2022

Leakage or seepage in reservoirs and dams has the potential for structural instabilities persuaded by water leakage pathways and linked to economic consequences. An environmental isotopic and hydrochemical research was conducted to determine the source and origin of seepages on the tunnel of Pandanduri dam, Lombok Island, Indonesia. This study aimed to examine the source of the tunnel leak on the dam site and the origin or source of water at the point of leakage based on water chemistry data and stable isotopes. To identify the source of the leakage water in the tunnel dam, 33 samples of the leakage water, groundwater, reservoir water, river water, and rainfall water were taken for chemical and isotopic composition analysis. The field measured the reservoir level, spring discharges, and physicochemical parameters (EC, pH, TDS, TSS). The physicochemical parameters show that the leakages water is similar to reservoir water. The types of leakage water in the tunnel belong to alkaline water, predominantly sulfate-chloride. This type of water is deep groundwater with a higher sulfate and chloride concentration than surface water or shallow groundwater. Hydrochemical and isotope analysis showed that water origin at leakage points is dominated by groundwater.

Published: October 2022

The rise of the batik industry in Jambi Province causes the accumulation of waste in the environment. Disposal of batik dye wastewater directly into the environment is one source of heavy metals entering the river. Palm Oil Fuel Ash (POFA), as a part of waste originating from combustion residues of oil palm, is potential to be used as a low-cost adsorbent in overcoming the batik dye wastewater problem. The POFA is also potential to be used in the removal of heavy metals and chemical and organic compounds in industrial waste treatment. This paper reported the potential use of POFA and the modification of POFA as batik dye adsorbents in overcoming waste problems from the batik industry. Results of this study showed that POFA could adsorb the dye in batik waste with up to 22% removal efficiency and adsorption capacity up to 62 mg/g. The isotherm adsorption in this study was in accordance with the Freundlich model that showed adsorption occurred at multi-layer and heterogeneous surfaces. The adsorption process occurred endothermically and spontaneously.

Vegetation can be an important indicator of ecosystem change, the influence of anthropogenic and non-anthropogenic factors. Therefore, it is important to study the dynamics of vegetation changes. One technique that can be used for vegetation analysis is the Normalized Difference Vegetation Index (NDVI). NDVI is an indicator of the active biomass that helps distinguish vegetation from other land cover and can provide information about changes in Spatio-temporal vegetation dynamics, thus allowing for assessment of the ecological conditions. This study aimed to investigate the dynamic of vegetation in the Sangkub watershed area located in North Sulawesi Province. This analysis used geospatial technology with the NDVI method, utilizing Landsat 5 and Landsat 8 satellite imagery data in three periods the year 2000, 2015, and 2020. The results showed that vegetation cover of the Sangkub watershed decreased substantially, whereas the non-vegetated area increased gradually over time.

Stress is a normal and necessary response, it functions as a defensive response, whether subjectively or objectively (1). It produces the experience of a dangerous situation, which explains why some people are afraid of empty spaces and others. We are living in perilous times, and we cannot deny their existence. Since the coronavirus is circulating, it is not surprising that everyone may be stressed (2, 3). This virus, presented suddenly as a situation no one knows about, was something new that adds to our lived experience, and it is normal for it to cause uncertainty, anxiety, or stress (4).

Authors: Madou Karel , Pribish Chris
Published: October 2022

Introduction: In team sports with short repeated sprints and changes of direction, it is important to know how the anaerobic capacity level of his players is and develops during the season. To test this ability the 15m Modified Shuttle Run Test (15m MSRT), based on the Wingate Cycle Test principles, was developed. Method: Two groups of five female soccer players from Germany (GER) (average age 19.2 years; range 18–21) and the United States of America (US), (average age 18.8 years; range 17–21) performed a 15m MSRT on two occasions to test the reliability. Maximum (Highest Lap Velocity (HLV)), minimum (Lowest Lap Velocity (LLV)) and average speed (Mean (Individual) Velocity (M(I)V)) of the individual player and average lap speed (Mean Lap Velocity (M(L)V)), the Fitness Index (FiI), Fatigue Index (FaI) and Speed–Endurance–Index (SEI) was calculated for the individual player as well as for the whole team. Results: The ICC and CV for the MLV was 0.95 and 1.41% resp (GER) and 0.72 and 3.24% (US), the Fitness Index (GER: 0.93 and 2.90%; USA: 0.78 and 4%) and Speed–Endurance–Index (GER: 0.95and 3.30%; US: 0.94 and 4.40%) Conclusion and recommendation: The 15m MSRT is a reliable tool to assess and monitor both individual and team running speed. The MIV is useful to individualize anaerobic capacity training.

A total of 145 flint items, as well as four obsidians and seven stone-made artefacts, were collected during the excavations on the Linear Pottery culture settlement Modrychi-1 in Lviv Oblast, which is located within Ukrainian Outer Subcarpathia. The assemblage of flint and obsidian items has been analyzed as an integral complex that characterizes the material culture of the Neolithic settlement. The prevailing number of flint items such as cores, flakes and blades reflect on-site production. As for the obsidian artefacts, an attempt was made to establish the origin of raw materials.
How to Perform Quality Improvement Projects

Published: October 2022

Safety and efficiency remain salient concerns for the US health-care system, especially in the face of growing health-care costs and morbidity from low-quality care. Current estimates suggest that more than 20% of health-care costs in the United States represent waste and low-value care, presenting numerous improvement opportunities. Although current guidelines and standards aim to address these problems, system processes and clinician behavior must also change to fill care gaps in the health-care system. Quality improvement (QI) is a systematic approach to safety or value gaps in care that uses data measured over time and then makes sequential, small changes to achieve a measurable aim. The Model for Improvement provides a general framework for approaching QI. In this review article, we describe the general approach to conducting QI studies in the health-care setting using the Model for Improvement as a guide, including identifying a problem, performing testing, measuring change, and implementing successful ideas. We also summarize common issues that QI teams face and should consider if sharing their QI work through publication. By following a systematic approach, QI teams can develop and implement interventions aimed at addressing gaps in care, thereby improving overall health-care value and safety for their patients.

Automated breast ultrasound is a three-dimensional ultrasonographic technique allowing the evaluation of women with dense glandular breast tissue. In this group of patients, mammography has a low sensitivity because dense breasts can obscure breast cancer on mammogram. On the other hand, women with dense breast tissue, types C and D on the BI-RADS scale, are at an increased risk of developing breast cancer compared to women with fatty breast tissue. Automated breast ultrasound is a standardized and reproducible ultrasound technique which improves breast cancer detection and is promising in the screening and diagnostic settings: it increases the detection of breast cancer, and helps to differentiate benign and malignant lesions. Unfortunately, automated breast ultrasound also has its limitations and disadvantages due to artifacts caused by poor positioning, and lesion and patient characteristics. Many artifacts can be avoided by training and experience of the performing technician. Furthermore, familiarity of the interpreting breast radiologist with these artifacts and pitfalls will decrease false negative diagnosis of true lesions.

Aim of the study: Seromas are rarely reported as complications of autologous arteriovenous fistula creation. Case description: An 89-year-old woman was hospitalized for hemodialysis and underwent an autologous arteriovenous fistula creation in the forearm. During cephalic vein expansion using a heparinized saline solution, leakage occurred. A suture was placed to control the leakage, and a Penrose drain was inserted. Serosanguineous drainage ceased on postoperative day two; however, a seroma occurred approximately two weeks after the surgery. Follow-up ultrasonography revealed no growth tendency; therefore, excision and aspiration were unnecessary. Conclusion: This seroma was associated with postoperative dead space, surgical technique, and patient clinical status. Sufficient preoperative ultrasonographic vascular mapping is required to avoid inappropriate handling of veins and prevent seroma formation. Postoperative ultrasonographic follow-up is recommended due to the future risk of fistula dysfunction and infection associated with seroma enlargement, which may necessitate surgical seroma excision.
