Impact of New Zealand teenagers’ fertility intentions on childbearing
Authors: Sligo Judith L. , Hohmann-Marriott Bryndl E. , McAnally Helena M. , Hancox Robert J.
Published: April 2023

Objective:

To assess the impact of age 15 fertility intentions on childbearing outcomes three decades later.

Background:

Evidence is mixed about the implications of teenage fertility intentions on later childbearing. Taking a prospective life course approach to assessing intentions and outcomes may help clarify these mixed findings.

Method:

A general population birth cohort (born 1972/73) was asked about their fertility intentions at age 15 and 775 of this sample (384 women, 391 men) provided data on their childbearing between ages 15 and 45.

Results:

At age 15, almost all of the sample indicated they would like to have children in the future (93%). Most (79%) reported having had a biological child by they time they were 45; but those who professed to not wanting children as teenagers were significantly less likely to have had a child three decades later.

Conclusion:

Fertility intentions during adolescence are probably influenced by social, political and economic norms and may influence later childbearing decisions. This may be particularly true for those whose intentions counter established norms around childbearing.

Implications:

A life course framework is useful for examining the relationship between hypothetical fertility intentions and outcomes.

Authors: Rahayu Dea Santika , Yanti Meili , Lestari Ayu
Published: April 2023

Multiple representation ability is a student's understanding of describing a concept at three chemical representation levels: macroscopic, submicroscopic, and symbolic. This ability represents a complete understanding of chemistry, so every teacher needs to know. This research was conducted to analyze students' multiple representation abilities in voltaic cell material using the Predict-Observe-Explain (POE) diagnostic test. This study uses a qualitative descriptive method to obtain an overview of the ability of multiple representations naturally. The instrument uses the POE diagnostic test, has been validated by five validators consisting of lecturers and chemistry teachers and has been tested to obtain instrument legibility. The research subjects involved 34 class XII high school students who had studied voltaic cell material. The findings of the ability profile of multiple representations include (1) the concept of voltaic cell construction; most students (32.35%) are able to understand the constructs at the macroscopic and symbolic levels accompanied by explanations at the submicroscopic level that are not correct, (2) the concept of calculating values standard cell potential, as many as 44.12% of students were able to observe (macroscopic) and calculate (symbolic) the standard cell potential value accompanied by an inaccurate submicroscopic level explanation, (3) most students (32.35%) were not correct in explaining cell voltaic in alkaline batteries at the macroscopic and submicroscopic levels accompanied by writing at the appropriate symbolic level, and (4) the concept of corrosion, most students (35.29%) were able to explain corrosion phenomena at the macroscopic and symbolic levels accompanied by explanations at the submicroscopic level which less correct.
The impact of attentional centering on ergative marking in Tima
Authors: Schneider-Blum Gertrud
Published: April 2023

One of the languages on the African continent which displays ergative features is Tima, a Niger-Congo language spoken in the Nuba Mountains of Sudan. In this contribution, the impact of attentional centering – influenced by factors including the animacy of the participants, the identifiability of the agent, and the givenness of either A or P participant – on the choice of construction between AVO and OVAergis investigated. The research brought forth the following findings: token-identifiable human agents typically trigger an AVO constituent order; type-identifiable human agents typically trigger anOVAergconstituent order; the event described may or may not be decomposed into two sub-events; inanimate agents acting on human animates trigger a decomposition of the event into two sub-events: first, P is presented, and second, A is introduced as an ergative-marked participant following the verb. The information structural device of givenness interacts with the two parameters of agent-identifiability and animacy. A given agent always leads to an AVO construction. A given patient finds the speaker faced with the choice of opting for an AVO or anOVAergconstruction.
Visualizing the conceptual space of pluractionality
Authors: Denk Lukas
Published: April 2023

This paper seeks to improve the understanding of the conceptual structure of pluractionality, a bundle of functions denoting the plurality of events. By conducting a multidimensional scaling analysis on 366 marking strategies from the 183-language sample in Mattiola, Simone (2019. Typology of pluractional constructions in the languages of the world. Amsterdam & Philadelphia: John Benjamins), a spatial model is presented showing the semantic distance of pluractional functions as Euclidean distance. This quantitatively induced conceptual space differs in some way from the space proposed by Mattiola (2019) comprising data from only a small fraction of the sample. The analysis reveals that the conceptual space could be interpreted as defined by two prominent dimensions: a vertical dimension that represents the boundedness of events and a horizontal dimension that represents participant-oriented versus event-oriented plurality.

Published: April 2023

To date, there has been little attention focused on jade powder, the leftover of the jade polishing process, although jade has been long considered precious and valuable. Herein, jade powder was characterized, followed by an investigation on its biocompatibility and bactericidal effects. Characterization conducted by scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, and Fourier-transform infrared spectroscopy showed that the main component of jade powder is tremolite, which is in good crystallization with no typical peaks of possible impurities observed. Tremolite’s main elements are oxygen, calcium, magnesium, and silicon, all of which exist in the form of oxides. Water contact angle, trace element content, and in vitro cytotoxicity analyses demonstrated that jade powder is of hydrophilicity and good cytocompatibility and contains only parts-per-million-level heavy metals. Meanwhile, antibacterial evaluation proved that the jade powder had excellent antimicrobial effects against both gram positive and negative microbes such as Escherichia coli and Staphylococcus aureus. This study suggested that jade powder is a promising material that could be used in the fields of biological and medical applications.

Authors: Yu Yinshan , Zhang Hongyun
Published: April 2023

This paper presents a method for detecting the concentration of difenoconazole in lake water-quality detection based on spectrophotometry. Prediction models were established by using various parameters to detect the concentration of difenoconazole. The results showed that the concentration of difenoconazole had a good linear correlation with total nitrogen and ammonia nitrogen. To verify the accuracy of the measurement method, the total nitrogen and ammonia nitrogen of different concentrations of liquids were tested, and the concentration of difenoconazole predicted by the model equation was obtained and compared with the actual value. The results show that the prediction correlation coefficient of the equation is close to 1, and the standard error of prediction is small, which meets the actual test requirements.

Authors: Stiles Ciara , Batchelor Rachel , Gumley Andrew , Gajwani Ruchika
Published: April 2023

Individuals with a diagnosis of borderline personality disorder (BPD) typically experience discrimination and stigma, resulting in poor identification and delayed care. We conducted a review to examine and synthesize qualitative studies exploring experiences of stigma and discrimination among individuals with BPD. In August 2021, we systematically searched the following databases: Embase, Medline, Cochrane Library, PsycINFO, and Cinhal. We also hand searched reference lists and Google Scholar. We then synthesized studies using meta-ethnography. We included seven articles in the study, all of high or moderate quality. Five themes were identified: (1) resistance from clinicians (withholding information), (2) othering, (3) negative impact on self-image/esteem, (4) hopelessness surrounding the perceived permanency of BPD, and (5) feeling like a burden. This review highlights the need for improved understanding of BPD across health care services. We also discussed the need to introduce a standardized pathway of care across health services following a BPD diagnosis.

Published: April 2023

We aimed to explore the heterogeneity of schema therapy regarding (a) patient characteristics, (b) content, and (c) way of delivering schema therapy. A search was conducted of the electronic databases EMBASE, PsycINFO, Web of Science, MEDLINE, and COCHRANE up to June 15, 2022. Treatment studies were eligible if they (a) used schema therapy as (component of) the intervention examined, and (b) reported an outcome measure quantitatively. A total of 101 studies met the inclusion criteria, including randomized controlled trials (n = 30), non-randomized controlled trials (n = 8), pre-post designs (n = 22), cases series (n = 13), and case reports (n = 28), including 4006 patients. Good feasibility was consistently reported irrespective of format (group versus individual), setting (outpatient, day-treatment, inpatient), intensity of treatment, and the specific therapeutic components included. Schema therapy was applied to various (psychiatric) disorders. All studies presented promising results. Effectiveness of the different models of schema therapy as well as application beyond personality disorders should be examined more rigorously.
Crisis and Praxis in Lukács’History and Class Consciousness
Authors: Kavoulakos Konstantinos
Published: April 2023

In Lukács’ early Marxist thought in the 1920s, crisis is understood as an expression of a deeper dissonance of social life that reveals the violence inflicted upon humans even in “normal” social conditions. The experience of crisis can thus lead to new forms of social consciousness and, consequently, to a “revolutionizing praxis.” However, this transition is in no way mechanically necessary, as crisis can also be perpetuated and temporarily “overcome” through the restoration of dominant power relations. However, the relative instability of the system during a crisis calls us to think about the appropriate forms of organizing collective political practice to effectively intervene in the historical continuum, instead of letting historical automatism be restored.
Claudia Jones, theWest Indian Gazette and Afro-Asian-Caribbean Newsand the Rise of a New Black Radicalism in the UK and US
Authors: Smethurst James
Published: April 2023

In recent years, considerable scholarly attention has been paid to the Black Communist Claudia Jones as a progenitor of Black radical feminist notions of intersectionality. In Britain, Jones has also been hailed as an important part of the Black British political and cultural radical tradition. Less studied is how Jones brought a U. S. Black Left institution-building sensibility to the UK, particularly as embodied in the West Indian Gazette and Afro-Asian-Caribbean News (WIG) newspaper, helping to lay the foundation for the growth of Black Power and Black Arts in the UK. In turn, Jones and WIG brought to Black radicals in the U. S. a renewed sense of Black internationalism inspired by Africa's crossroads and its diaspora in London and other major British cities.
The Role of Valence Matching in the Truth-by-Repetition Effect
Authors: Béna Jérémy , Mierop Adrien , Bancu Douglas , Unkelbach Christian , Corneille Olivier
Published: April 2023

People judge repeated information as truer than new information, a “truth-by-repetition” effect. Because repetition increases processing fluency, which is assumed to elicit positive affect, participants may match their positive experience associated with repeated information with a positive (“true”) rather than negative (“false”) response. We tested this valence-matching hypothesis in a preregistered experiment by manipulating the affective congruency of the response format. Specifically, in the congruent condition, participants had to select a positive (negative) picture to respond “true” (“false”). In the incongruent condition, we reversed these associations. In line with the valence matching hypothesis, the truth-by-repetition effect was larger in the congruent than incongruent condition. However, the effect was small, and Bayesian analyses were inconclusive. In addition, the truth-by-repetition effect was significant in both response format conditions. The results suggest a possible contribution of a valence matching process to the truth-by-repetition effect, but one that does not challenge extant models.

Published: April 2023

Organic matter (OM) has a very crucial role in the management of acid mine drainage (AMD) using a passive treatment system, although information on the use of this system in different reclaimed-mining soils (RMS) is very limited. Therefore, this study aimed to determine the effect of adding OM to RMS with different characteristics. It was carried out by adding only OM or in combination with coal fly ash (CFA) to two RMS with different characteristics (Palam and Cempaka Soils) and quartz sand (control) in a batch reactor experiment. This was followed by the incubation of the mixture of soil/quartz-OM or soil/quartz-OM-CFA at 60% water holding capacity for 15 days. After incubation, AMD slowly flowed into the reactor, and its pH in the reactor was monitored every day for 30 days, while the concentrations of Fe (iron), Al (aluminum), and Mn (manganese) were measured on the 30th day. The results showed that the application of OM on Palam Soil only increased AMD pH by 0.38 units, while Cempaka Soil and quartz sand increased by 4.83 and 5.36 units, respectively. The addition of OM to Cempaka Soil and quartz sand also showed a higher reduction in heavy metals concentration in AMD than those in Palam Soil. It was also discovered that the application of OM combined with CFA led to a higher improvement in AMD quality than only using OM. This study demonstrated that the effect of OM addition on increasing pH and decreasing metal concentration on AAT management with the passive treatment system is controlled by soil characteristics.

Published: April 2023

The Lantung area is one of the places on Sumbawa Island with a large gold deposit. One of the activities of the Lantung people that has the potential to damage the environment is separating gold from mercury. This study aimed to examine the activity of the gold laundering process, and the level of contamination of groundwater and river water due to gold processing from amalgamation by mercury (Hg+) waste. In this study, sampling was carried out for each location, namely two samples of wastewater, six samples of river water, and two samples of groundwater, which were then tested in the laboratory on the parameters of mercury and TSS. At the same time, pH was measured in the field. Furthermore, from the survey results, it was found that the use of mercury was ±150-250 mL at each gold processing location. The results showed that all samples from wastewater (tailings), groundwater and river water were contaminated with mercury with levels exceeding the acceptable quality standards. Furthermore, the status of water quality using the Pollution Index (IP) method shows that wastewater is light to moderately polluted, groundwater is lightly polluted, and river water is also lightly to moderately polluted.

Published: April 2023

Ultisols have considerable potential in developing agricultural cultivation, but in their management, they face several obstacles, including physical properties that do not adequately support plant growth. The low content of soil organic matter causes poor soil physical properties. Low organic matter content leads to low soil aggregate stability, obstructing pore distribution and infiltration so the soil can easily become compacted. This study aimed to observe the changes in some physical properties of the soil due to the application of cow manure and Gliricidia sepium pruning compost and its effect on the yield of soybean plants. This study used a randomized block design with five treatments, namely, K0 (without cow manure-Gliricidia compost), K1 (5 t ha-1cow manure-Gliricidia compost), K2 (10 t ha-1cow manure-Gliricidia compost), K3 (15 t ha-1cow manure-Gliricidia compost), and K4 (20 t ha-1cow manure-Gliricidia compost). The results showed that the 15 t ha-1 cow manure-Gliricidia compost was the best dose in improving the total pore space and penetration resistance of the soil studied. The application of 15 t ha-1cow manure-Gliricidia compost significantly increased soybean yield, reaching 2.97 t ha-1.
Application of triple bottom line concept to artisanal and small-scale mining activities in Wa East District, Ghana
Authors: Mensah-Abludo Emmanuel , Peprah Kenneth , Baddianaah Issah
Published: April 2023

The artisanal and small-scale mining (ASM) sector offers a supplementary livelihood strategy to agriculture in northern Ghana, acting as a source of capital to support agriculture. However, the sector has been associated with several adverse environmental and socio-economic consequences, making its sustainability dimensions extremely complex and inconclusive across the literature. This study sought to investigate the dynamics of ASM operations in line with the Triple Bottom Line concept. Specifically, the paper explored the influence of the small-scale mining law and institutional framework on ASM operations, examined the relationship between the economic benefits of ASM and other livelihood activities, and assessed the adverse environmental effects of ASM in the host communities. The research design was a mixed method and cross-sectional survey. Household questionnaires, semi-structured interviews and non-participant observation were the main primary data collection techniques. Secondary data were provided by satellite images sourced from USGS Earth Explorer. They were analysed to determine the land cover types. The results indicate that the relevant regulatory state institutions lag behind their law enforcement duty. The ASM is a lucrative job that provides quick income to the youth. However, ASM activities affect food crop farming and decrease the quantity and quality of vegetation causing variations in land cover. Consequently, the host communities and ASM cooperatives have employed some land reclamation strategies. The study recommends increased government support to the relevant regulatory state institutions to constantly monitor and sanitize the ASM sector. To eradicate illegal mining, the study advocates for multi-stakeholder consultation and action.

Published: April 2023

The paper discusses the environmental impact of industrial minerals mining. Research shows that interest in mining of industrial minerals increases year by year, and their demand and consumption will steadily grow. The market conditions are favorable for developing new fields. Both opencast and underground mined minerals are most popular these days. The industrial minerals market analysis indicates its dynamics, but the high monopoly degree of mining of certain minerals causes some restrictions on free competition in subsoil use. At the same time, environmental issues raised at the level of world power governments are not reflected in legislative documents. We raise the possibility of partial transition from opencast mining to underground one-as an alternative that carries environmental improvement of a mining area.

Published: April 2023

Purpose: the purpose of this study was to establish morphometric parameters that correlate with the reactivity and recovery of blood pressure in response to a standard physical load in athletes of various game sports.

Material & Methods: to achieve the set goal, 101 qualified male athletes engaged in game sports were examined. All examined represented 3 game sports: 13 – water polo (average age 27.3±6.3 years), 59 – volleyball (average age 21.1±2.5 years), 29 – handball (average age 20.9±2.8 years). The morphometric study was carried out by traditional methods and included the determination of body length (BL, cm), body weight (BW, kg), chest circumference (CC, cm) with calculation of chest excursion (CE, cm), hand dynamometry, vital lung capacity (VLC, ml). Body mass index (BMI, kg×m–2), vital index (VI, ml×kg–1) and Erismann index (IE, c.u.) were calculated separately. The Martine test (20 squats in 30 seconds) was performed according to the traditional method.

Results: changes in SBP in response to load were the significantly greater in handball players compared to water polo players (p=0.025) and compared to volleyball players (p=0.022). Changes in SBP during 3 minutes of recovery are not related to morphometric parameters and obey the general mechanisms of changes in hemodynamic support under the influence of physical load. Changes in DBP during 3 minutes of recovery are related to chest circumference (CC, cm) and proportionality of its development (IE, c.u.) in volleyball and water polo players, and with BW (kg) in handball players. Changes in PBP during 3 minutes of recovery in handball players are not differentiated, in volleyball players they are related to the proportionality of chest development (IE, c.u.), and in water polo players to the BW (kg), CC (cm), mobility and proportionality of chest development (CE, cm and IE, c.u.).

Conclusions: the obtained results confirm that changes in DBP and PBP in response to physical load and during the recovery period after it are related to the morphometric parameters of the body, which can characterize the mechanisms of hemodynamic maintenance recovery and be useful in the selection and the organization of recovery measures in certain sports sport.
Effect of lower torso training on asthma patients
Authors: Shimal H. Hamad  , Ammar Hamza Hadi  , Bestoon Akram Ahmad
Published: April 2023

Purpose: the researchers see that this project is significant for asthma patients to help them improve. Therefore, this study hypothesizes that lower torso muscle endurance may affect 6MWT in asthma patients. To test this hypothesis, we examined the effect of decreased thoracic muscular endurance on asthma patients' 6-minute walk test (6MWT).

Material & Methods: this study included two groups (experimental and control), and they used a quantitative descriptive technique and achieved Pre – Post tests research design. The researcher began by administering a pre-test to the two groups. Researchers then carried out the therapy to experiment group, whereas the control group used the hospital protocol. Following the conclusion of the treatment, the researcher conducted a post-test for both groups. The program of the treatment's impact may be determined precisely by comparing the pre-and post-test findings. The trial lasted 24 meetings, with training occurring three times a week. On many occasions, twenty asthmatic patients from Imam Sadiq Hospital who had been hospitalized at a pulmonary rehabilitation center were assessed. Patients were included if they met the global effort for asthma recommendations for asthma diagnosis. The current study employed an experimental design. This study evaluated the maximal inspiratory pressure (PI, max), the pulmonary function test, the baseline dyspnea index (BDI), and the six-minute walk test (6MWT). Each exercise (leg extension and leg press) on gymnasium equipment was assigned a one-minute repetition. Additionally, the St. George Respiratory Questionnaire (SGRQ) was used to determine a person's quality of life. The researchers discovered that a training program had statistically significant favorable impacts on the 6MWT and body weight.

Conclusion: this study's findings demonstrated the critical role of lower torso training in achieving submaximal exercise tolerance. Additionally, they may pave the way for new avenues for training programs aimed at increasing functional activity in asthma patients.

Published: April 2023

Purpose: to determine the relationship between the functional state of the pituitary-thyroid system and the growth hormone/insulin-like growth factor type 1 (GH/IGF-1) system in adolescents with type 1 diabetes mellitus (DM1) during puberty

Material & Methods: 165 children (85 girls (51,5%) and 80 boys (48,5%) aged 8 to 18 years old who have DM1 and are in the endocrinology department of the State Institution "Institute for Children and Adolescents Health Care at the National Academy of Medical Sciences of Ukraine" (SI "ICAHC NAMS"). The criterion for inclusion in the study was the duration of DM1 for more than one year (from 1 to 16 years). The level of thyrotropin (TSH), free fractions of thyroxin (fT4) and triiodothyronine (fT3), GH and IGF-1 was determined and the ratio (fT3/fT4 and TSH/fT4) was calculated. Study participants were divided into groups depending on the level of sexual development (T1-T4) at the time of the study, assessed by the Marshall & Tanner scale (Marshall & Tanner, 1969; Marshall & Tanner, 1970); functional state of the pituitary-thyroid system: (euthyroidism (TSH/fТ4 <0,19 c.u.), minimal thyroid insufficiency (0,19 c.u. ≤ TSH/fТ4 ≤0,29 c.u.), with subclinical hypothyroidism (TSH/fТ4 >0,29 c.u.) (Turchina et al., 2016).

Results: it was found that among adolescents with DM1, almost every child has signs of thyroid dysfunction. An increase in the fT3 level and the fT3/fT4 ratio were more often diagnosed. The frequency of increase in the level of TSH and the ratio of TSH/fT4 fluctuated widely and depended on the sexual development of the child. More often, signs of SGH were determined during early puberty (23,5%), which probably exceeded those in prepubertal (16%, Pφ<0,05), proper (8,9%, Pφ<0,05) and late puberty (6,1%, Pφ<0,05). These changes indicate the tension of the thyroid system at the beginning of puberty, which is the basis not only for an increase in the risk of thyroid pathology in this period of puberty, but also for violations of physical and sexual development.

Conclusions: almost a third of adolescents with DM1 had signs of thyroid insufficiency of varying degrees, which was most often determined during early puberty. The progression of thyroid insufficiency was accompanied by a decrease in the level of GH and IGF-1.

Published: April 2023

The secondary metabolite of Leucojum aestivum lycorine, is of high medicinal value and has attracted much attention internationally. Therefore, it is essential to review and analyze the existing literature on L. aestivum to clarify the research progress, research bottlenecks, and applications of lycorine in landscapes. In this study, we used the Web of Science (WOS) and CNKI Chinese journal database as data sources to analyze the bibliometric analysis of L. aestivum-related literature in terms of the number of publications, journal sources, research institutions, keywords, and co-cited literature using Citespace visualization software. The results showed that the number of L. aestivum-related studies decreased compared to previous years, but the number of publications showed a high growth trend in this research frontier. Bulgaria has a significant dominance in L. aestivum-related research, while China has fewer publications in this field but focuses more on the frontiers of the discipline. The frontiers of L. aestivum research concentrate on improving in vitro culture devices, changing plant culture strategies, and adding chemical additives to improve the yield of compounds in plants; new methods for lycorine synthesis; identification of ornamental plant species and detection of compounds by electrochemical methods; practical applications of lycorine in medicine and its mechanism of action. It is inferred that future research will focus on the ornamental value, medicinal value, cultivation methods, and innovation of lycorine synthesis methods of aestivum.

Published: April 2023

Mango anthracnose in mango in the tropical and subtropical regions of Mexico is a disease that induces serious economic losses, caused by Colletotrichum gloesporioides. The objective of this research was to determine the efficiency of integrated management for anthracnose control and to identify the critical moment for disease management. The work was carried out on cv. 'Ataúlfo', in Guerrero, Mexico, in three production cycles. The identification of the pathogen was confirmed and during a period of 11 months the abundance of spores in the canopy of the trees was examined. Three treatments were evaluated: integrated management with severe pruning (MIM-Pruning), integrated management without severe pruning (MIM) and Control treatment. The climate was conducive to the development of the disease (>80% incidence). The greatest increase in spores, with 65.9 to 84.1 spores/week, was observed during summer vegetative growth, in the phase of flowering and fruit set on the rachis, with its subsequent decrease in fruit growth. The MIM-Pruning and MIM treatment showed consistent results of less area under the disease curve progress (AUDCP), in foliage and flowering, causing a greater definitive fruit set per inflorescence and marketable fruits per tree with respect to the Control (P ≤0.05). Field pathogen population management should begin with the spraying of fungicide products in the summer vegetative growth phase and before the full flowering stage. Pruning is a practice that should be included in anthracnose management.

Published: April 2023

Acute renal failure (ARF) is a syndrome that occurs due to multiple causes of injury and is characterized by an abrupt decrease in glomerular filtration rate. The concept of renal angina is made to highlight the characteristics of renal injury, as an analogy to the concept of angina pectoris, which is used to increase the suspicion of acute coronary syndrome in cardiology. Material and methods: Prospective, observational and descriptive study. The present study will be carried out on patients admitted and attended in the Emergency Department of the Hospital de Alta Especialidad (UMAE) No. 14. Adolfo Ruiz Cortínez from September 1 to November 30, 2022. The data described in the data collection instrument will be collected in order to later concentrate them in a database for analysis. Results: Of the 73 patients who entered the study, 42 patients were male, the mean age was 55 years, the minimum 18 and the maximum 75, the mode was 70 years. Of the patients included 49 were diabetic and of these 38.36% were male, only 11 had sepsis without much difference between the two sexes, representing 15.07% of the total number of patients. Of the total number of patients only 12 were admitted to the intensive care unit, 16.44%; the male sex was the most prevalent group, only 23.9% of the total number of patients required mechanical ventilation and 10.96% required vasopressor (Of the total number of patients only 15 (20.5%) had acute renal injury and of these the most affected age group was 61 to 80 years old). Conclusion: The percentage of patients with a positive renal angina index (>8) who had AKI was 100% of the 73 patients only 15 developed AKI. Sepsis, vasopressor use and mechanical ventilation did not have a significant value for the development of AKI within this study in comparison to the study "Renal angina: "The beginning of the end" where out of 95 patients included in their study, sepsis, vasopressor use and mechanical ventilation did have a significant value for the development of AKI.
Human hydatid disease and its effect on bones and joints: edital
Authors: Gracio MA
Published: April 2023

In this short note, we present general information on Echinococcus granulosus and its impact on human health. Our objective is to alert physicians and health professionals to hydatid cyst locations in humans, with emphasis on bones and joints, and the necessity for special care before, during or after surgery. Effectively, opening of a hydatid cyst requires special care not to spill the contents into the peritoneal cavity or tissues, since this may result in an anaphylactic reaction to the spilt fluid or in dissemination and implantation of the immature scolices contained in the “sand” in the fluid. Incomplete removal of viable germinal epithelium from the liming of a hydatid cyst results in the formation of multiple cysts.
Non usual urban sounds in a western neighborhood of Havana city
Authors: Barcelo Perez Carlos , Gonzalez Sanchez Yamile
Published: April 2023

Main noise source in the city of Havana is road traffic, but many noise complaints are connected to a mechanical source and audio exposures as level induced from air conditioners or fun which escapes from entertainment places. Last year some complaints by noise exposure to the so called “noise attacks” were referred by American diplomats. This paper intends to present a sound characterization of possible noise events experienced including audible structure of this acoustic episodes (target sound). Article could contribute to clarify nature of the so-called noise attacks which have worsened the diplomatic relations between the United States and Cuba. Some recordings of the target sound supplied were assessed and also, background noise was featured through sound level measurements. It was watched that background noise at night is connected several times to presence or absence of crickets calls in green spaces at a residential neighborhood, Western of Havana. Target sound is described on behalf its possible noise level and frequency structure, by two main shapes, one of them reflects a broadband noise with a high pitch overlapped. The other one has no high frequency (pitch). Several target sounds episodes recorded show certain likeness to the background noise with cricket sounds added. Ultrasounds and microwaves are not supported as source of target sounds connected to noise attacks. Sound estimated levels and frequency structure do not support hypothesis of induced health impairment. Sometimes target sound level is weak, close to background. Directional sound seems not able to penetrate isolated built environment.
Implication of social theories in covid-19: a succinct reflection on Bangladesh society

SARS-CoV-2 or Covid-19, has emerged as the most serious public health threat of the contemporary age. More than 6.8 million individuals have died as a result of this infectious virus, which has infected about 673 million people. Coronavirus spread quickly across the world due to its infectious nature, resulting in a large number of deaths. In many ways, Covid-19 had an impact on nearly every nation in economic, social, cultural, political and other spheres. This paper is an attempt to identify major social determinants of Covid-19 worldwide with an extensive focus on Bangladesh society. The paper is primarily based on secondary sources like journal article, newspaper reports, research reports and validated website contents. The paper revealed that determinants of Covid-19 vary concerning the population, geographic location and other factors. In terms Bangladesh society, predominantly in urban areas, poverty is found to be a major determinant as well as impact of Covid-19. At the one hand, poor people tend to be more exposed to get infected by coronavirus; on another, Covid-19 induced lockdown in many ways crippled economic growth and triggered job loss and unemployment which contributed to increase poverty and marginality. Other social factors like social class, status, physical environment, health seeking behavior, and illiteracy are also found to be major determinants of Covid-19 infection.

Published: April 2023

Introduction. Distributing public funds to the “best” researchers is a key element of the science policy. Evaluation is a fundamental activity for the allocation of competitive funding. The flaws of peer review have led to increased interest in the use of bibliometric indicators for the evaluation of the research project proposals.Problem Statement. The advantajes and advance of bibliometrc is stimulated interest toward the correlation of peer review and applicants’ bibliometric indicators. The results of such studies are different and heterogeneous. Such studies are insufficient in Eastern Europe.Purpose. To establish the correlation between peer review and bibliometric indicators of project team leaders within the call for research projects in Moldova, which are financed from public funds for 2020—2023.Material and Methods. Statistical correlation of the results of national competition of R&D proposals (evaluation and funding) and the bibliometrics indicators of project team leaders (publications ant patents); analytical analysis of the contextual factors influencing this correlation.Results. The results of the analysis have shown a positive, albeit weak correlation between the scores assigned by experts and the previous performances of leaders. The most significant relation is between the call results and the Hirsh index in Web of Science and Scopus databases. However, the projects proposed by the most cited researchers in WoS and Scopus or the founders of scientific schools did not receive funding.Conclusions. The analysis of the national R&D competition has proved that previous scientific performance of team leaders influenced the evaluation results and the funding of project proposals. However, these dependencies are not linear and seem to be affected by the conflicts of interest and “old boys” schemes. This fact calls for significant changes of the process: ensuring the transparency, the involvement of foreign experts and the use of bibliometric indicators in evaluation.
Neonatal Hypocalcemia: Common, Uncommon, and Rare Etiologies
Authors: Cheng Elaine , George Akeem A. , Bansal Sanjay K. , Nicoski Pamela , Amin Sachin
Published: April 2023

Calcium homeostasis in the neonatal period is a reflection of the transition from placental regulation to hormonal maturation in the newborn. Hypocalcemia occurring within the first 72 hours after birth, termed early-onset hypocalcemia (EOH), is more common and often asymptomatic. Hypocalcemia occurring beyond 72 hours of age is termed late-onset hypocalcemia (LOH). LOH is less common than EOH, and affected patients are more likely to be symptomatic. To prevent and treat hypocalcemia in the newborn, neonatal clinicians should be familiar with the common, uncommon, and rare etiologies of EOH and LOH, as summarized in this review.
The Role of Religious Centre in Monash University: Perspective of Three Indonesian Muslim Students
Authors: Aflahah St
Published: April 2023

This study aims to explore the perspective of three Indonesian Muslim students at Monash University concerning the availability of Religious Centre which facilitates some aspects of students’ spiritual inquiry. This study deals with the primary data through observation and semi-structured interviews as qualitative research. This research reveals that Religious Centre has a significant role in fulfilling students’ spiritual needs, including the prayer room for Muslim students, and also fosters students’ tolerance by putting prayer rooms for all religions in the same building. The university students found that Religious Centre is significant in preserving their religiosity and relieving them to perform prayers inside the campus. Likewise, it has eased students in managing academic challenges. In addition, this study found that Religious Centre has contributed to maintaining the religiosity of three Indonesian Muslim students: helping them cheering educational challenges and controlling their academic stresses.
Reviewer Assignment Problem: A Systematic Review of the Literature
Authors: Aksoy Meltem , Yanik Seda , Amasyali Mehmet Fatih
Published: April 2023

Appropriate reviewer assignment significantly impacts the quality of proposal evaluation, as accurate and fair reviews are contingent on their assignment to relevant reviewers. The crucial task of assigning reviewers to submitted proposals is the starting point of the review process and is also known as the reviewer assignment problem (RAP). Due to the obvious restrictions of manual assignment, journal editors, conference organizers, and grant managers demand automatic reviewer assignment approaches. Many studies have proposed assignment solutions in response to the demand for automated procedures since 1992. The primary objective of this survey paper is to provide scholars and practitioners with a comprehensive overview of available research on the RAP. To achieve this goal, this article presents an in-depth systematic review of 103 publications in the field of reviewer assignment published in the past three decades and available in the Web of Science, Scopus, ScienceDirect, Google Scholar, and Semantic Scholar databases. This review paper classified and discussed the RAP approaches into two broad categories and numerous subcategories based on their underlying techniques. Furthermore, potential future research directions for each category are presented. This survey shows that the research on the RAP is becoming more significant and that more effort is required to develop new approaches and a framework.
