Published: December 2023

Torrefaction emerges as an industrial process that increases the energy content of conventional biomass. Primary and secondary sludge are the main solid residues generated in the Effluent Treatment Plants of bleached kraft pulp mills, and can be considered as biomass. Typically, these wastes are sent to industrial landfills. The present study aimed to evaluate the technical feasibility of transforming the primary sludge (PS), secondary sludge (SS) and mixed sludges (MIX) into torrefied biomass for energy generation. Three temperatures (260, 290 and 320 °C) and three residence times (20, 40 and 60′) were used in the sludge torrefaction process. Increasing the torrefaction temperature and residence time of the sludges produced several benefits on their physical and chemical properties. They promoted an increase in the heating value, due to the elimination of less energetic compounds and the concentration of the fixed carbon content; caused a reduction of moisture, with a consequent increase in the lower heating value of the sludges; and led to a high energy yield and an increased energy density, important parameters in sludges energy generation. The treatment at 320 °C for 60′ obtained increases of 76%, 27% and 41% over the reference, for PS, SS and MIX, respectively.
Fetching felines: a survey of cat owners on the diversity of cat (Felis catus) fetching behaviour
Authors: Forman Jemma , Renner Elizabeth , Leavens David A.
Published: December 2023

Domesticated animals are famous for the ease with which they can accommodate to diverse human environments and roles, but less well-studied is the ease with which domestic animals can manipulate their human caregivers to their own ends. For example, domestic animals may start and end their play behaviour with humans at times of their choice. Here we present the results of a survey of 924 cat owners who report fetching behaviour in 1154 cats. The overwhelming majority (94.4%) of these owners report that fetching emerged in the absence of explicit training. Fetching was primarily first noticed when the cats were less than one year old (n = 701) or 1–7 years old (n = 415). Cats initiated and terminated fetching bouts more often than did their owners. Thus, cats who fetch demonstrate independent and co-ordinated agency in the onset and maintenance of fetching behaviour with their human partners. Additional findings highlight the diversity of objects fetched and the diversity in household demographics. Our thematic analysis reveals owners’ perspectives on (a) the process of a fetching session, (b) the initial acquisition of fetching, and (c) the circumstantial factors that influence fetching patterns. In summary, cats who fetch largely determine when they engage in fetching sessions and actively influence the play behaviour of their owners.

Published: December 2023

Dogs that have a vocabulary of object labels (Gifted Word Learner dogs—GWL dogs) have great potential as a comparative model for studying a variety of cognitive mechanisms. However, only a handful of studies, with a small sample size of 1 or 2 dogs, have examined this phenomenon. GWL dogs appear to share many of the same distinctive characteristics, but due to their rarity, it is not clear if these similarities are only anecdotal or indeed reflect characteristics that are similar in these rare individuals. Here we present the first study conducted on a relatively large sample of 41 GWL dogs that were recruited and tested using a citizen science model. After testing the dogs' receptive vocabulary of toy names, we asked the owners to complete a questionnaire about their and their dog’s life experiences. Our findings highlight several characteristics that are shared among most GWL dogs, such as their learning speed, their large vocabulary, and that they learned the names of the toys spontaneously, without the explicit intent of their owners. Our findings validate previous anecdotal evidence on common characteristics of GWL dogs and supply additional support to the hypothesis that these dogs represent a unique group of dogs.

Published: December 2023

Flexion-type pediatric humeral supracondylar fractures are rare, and the reduction technique remains contradictory. A minimally invasive technique using percutaneous leverage reduction combined with an external fixator was described to achieve satisfactory reduction and avoid the open reduction in this study. The operation and clinical results of patients treated with this technique were retrospectively compared with traditional closed reduction. From January 2013 to January 2018, children diagnosed with displaced flexion-type humeral supracondylar fractures were included in this study. Patients were treated with closed reduction (Group A) or minimally invasive reduction technique (Group B). The external fixator fixation was then applied. The demographic information, as well as the clinical and functional results of the operation, were retrospectively reviewed and evaluated. There were twenty-two patients, ten in Group A and twelve in Group B. The mean duration of the operation in Group A was more prolonged than Group B (59 min versus 46 min, p < 0.001). No infection, nonunion, myositis ossificans, neurovascular injury or other complications related to the operation were observed by the time the fractures healed. During an average 36 months follow-up time, almost all children achieved good to excellent results except for one fair in Group A according to the MEPS and the Flynn criteria. This study introduced a safe and efficient minimally invasive technique for displaced flexion-type supracondylar humerus fractures. With the assistance of mosquito forceps, this leverage technique might achieve similar satisfactory clinical outcomes as traditional closed reduction but with a shorter surgical duration.

Published: December 2023

Traditional methods for assessing plant health often lack the necessary attributes for continuous and non-destructive monitoring. In this pilot study, we present a novel technique utilizing a customized fiber optic probe based on attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) with a contact force control unit for non-invasive and continuous plant health monitoring. We also developed a normalized difference mid-infrared reflectance index through statistical analysis of spectral features, enabling differentiation of drought and age conditions in plants. Our research aims to characterize phytochemicals and plant endogenous status optically, addressing the need for improved analytical measurement methods for in situ plant health assessment. The probe configuration was optimized with a triple-loop tip and a 3 N contact force, allowing sensitive measurements while minimizing leaf damage. By combining polycrystalline and chalcogenide fiber probes, a comprehensive wavenumber range analysis (4000–900 cm−1) was achieved. Results revealed significant variations in phytochemical composition among plant species, for example, red spinach with the highest polyphenolic content and green kale with the highest lignin content. Petioles displayed higher lignin and cellulose absorbance values compared to veins. The technique effectively monitored drought stress on potted green bok choy plants in situ, facilitating the quantification of changes in water content, antioxidant activity, lignin, and cellulose levels. This research represents the first demonstration of the potential of fiber optic ATR-FTIR probes for non-invasive and rapid plant health measurements, providing insights into plant health and advancements in quantitative monitoring for indoor farming practices, bioanalytical chemistry, and environmental sciences.

HP501 is a highly selective renal urate transporter 1 (URAT1) inhibitor used for treating hyperuricemia. This study aimed to evaluate the tolerability, pharmacokinetics, and pharmacodynamics of HP501 in male Chinese patients. Patients with hyperuricemia were sequentially assigned to receive oral doses of HP501 (30, 50, 60, 90, and 120 mg) as a single dose on Day 1 and as once-daily doses from Days 4 to 13. Safety, pharmacokinetic, and pharmacodynamic data were collected. Multiple oral doses of HP501 were well-tolerated in all the cohorts. The most common adverse events (≥ 10% of patients) of any grade regardless of drug relationship were gout flare (14 patients, 25.93%), diarrhea (12 patients, 22.22%), elevated ALT (8 patients, 14.81%), hypertriglyceridemia (7 patients, 12.96%), dry mouth (7 patients, 12.96%) and oral ulcer (7 patients, 12.96%). All adverse events were mild or moderate. The Cmax and exposure (AUC) of HP501 was approximately dose-proportional between 30 and 120 mg. A dose-dependent serum uric acid (UA)-lowering effect was observed in the dose range of 30 to 60 mg and the serum UA lowering effect was similar between 90 and 120 mg on day 13, indicating that the maximal serum UA lowering effect of HP501 was achieved at 90 mg in the patients with hyperuricemia. In conclusion, the tolerability, pharmacokinetics, and pharmacodynamics supported 90 mg HP501 for subsequent clinical studies of this highly selective URAT1 inhibitor.

Published: December 2023

Batch processes are relevant to a wide variety of industries in chemical processes. In batch operations, water sources are almost not directly reused/recycled in process sinks without considering time constraints and storage tanks. However, storage tanks are usually expensive and thus a cost-effective water system has to be synthesized. Rescheduling the water network can contribute to reducing the cost of storage tanks by reducing their number and capacity. In the current research work, a goal programming is used to reschedule the water network in batch processes considering the time and storage tanks. A Mixed Integer Non-Linear Program model is introduced using the Lingo optimization program. This model is used to optimize multiple objectives, which are freshwater usage, wastewater discharge, the number and capacity of tanks, the degree of shifting streams, and the total cost of the water network. Three case studies are presented in this study to demonstrate the effectiveness of the proposed procedure, considering both single and multi-contaminants problems. The results of the first case study show a reduction in the network cost and the freshwater flowrate by 26.4% and 42%, respectively. Regarding the rescheduled water network results of the second case study, the cost is reduced by 24.6% and the freshwater flowrate is decreased by 21.8% with no requirement of storage tanks. The third case study highlights the model’s applicability to multi-contaminants problem, revealing a 15.1% cost reduction and a 25.7% decrease in freshwater flow.

Authors: Hong In Hwan , Cho Bum-Joo , Choi Se Hyun
Published: December 2023

Subconjunctival hemorrhage (SCH) is a benign eye condition that is often noticeable and leads to medical attention. Despite previous studies investigating the relationship between SCH and cardiovascular diseases, the relationship between SCH and bleeding disorders remains controversial. In order to gain further insight into this association, a nationwide cohort study was conducted using data from the National Health Insurance Service-National Sample Cohort version 2.0 from 2006 to 2015. The study defined SCH using a diagnostic code and compared the incidence and risk factors of intracerebral hemorrhage (ICH) and gastrointestinal (GI) bleeding in 36,772 SCH individuals and 147,088 propensity score (PS)-matched controls without SCH. The results showed that SCH was associated with a lower risk of ICH (HR = 0.76, 95% CI = 0.622–0.894, p = 0.002) and GI bleeding (HR = 0.816, 95% CI = 0.690–0.965, p = 0.018) when compared to the PS-matched control group. This reduced risk was more pronounced in females and in the older age group (≥ 50 years), but not observed in males or younger age groups. In conclusion, SCH dose not increase the risk of ICH and major GI bleeding and is associated with a decreased incidence in females and individuals aged ≥ 50 years.

Published: December 2023

Older adults have limitations from their aging process and chronic disease, so developed interventions must pay attention and concern to their aging degeneration and needs. This study aims to study the effects of a symptom management program on selected health outcomes among older people with chronic obstructive pulmonary disease. The quasi-experimental research included the 15 older patients in the control group receiving routine nursing care, while the other 15 in the experimental group received a 4-week symptom management program. First, the general information was analyzed using descriptive statistics. Next, the average health outcomes were analyzed using independent and dependent t-tests, Mann–Whitney U Test, and Wilcoxon Signed Ranks Test. In addition, the readmission rate was compared using Fisher’s Exact Test. Results revealed that most of the older patients were men (96.7%), aged 60–88 years (Mean = 71.57, SD = 7.75), with a smoking history (93.3%). The improvements were found in dyspnea (p < .01), its severity during activities (p < .01), and the quality of life (p = .04) among patients who attended the program. However, both groups did not have a different pulmonary function (p = .25) and the proportion of readmission within 28 days (p = .50). This study shows that the symptom management program can reduce dyspnea and severity during activities and improve the quality of life. Older people suffer from chronic obstructive pulmonary disease, especially when experiencing dyspnea. Therefore, it is crucial to have a symptom management program for older patients, especially a program developed to respond to changes in the aging process and the limitations of older people. This developed program was age-friendly to deal with symptoms and improve quality of life. However, this program should be explored in typical situations without the effects of the coronavirus disease (COVID-19) pandemic. In addition, more extensive population-based studies and randomized controlled trials should be adopted to increase credibility and ensure generalization.

Our current study aimed to investigate the association of preoperative OCT parameters with visual function after vitrectomy surgery in eyes with epiretinal membrane (ERM). This study enrolled 33 eyes with ERM that underwent vitrectomy surgery. In addition to visual acuity (VA), metamorphopsia was measured pre- and postoperatively for each eye. Using the preoperative horizontal and vertical OCT images, SUKIMA (the gap area between the ERM and retinal surface) was measured respectively and the average of horizontal SUKIMA and vertical SUKIMA was used for the analysis. The associations of baseline parameters (age, axial length, preoperative central retinal thickness [CRT], inner nuclear layer [INL] thickness, ectopic inner foveal layer [EIFL] and SUKIMA) with postoperative VA, the change in VA, postoperative metamorphopsia and the improvement in metamorphopsia were investigated using multivariate regression analysis followed by the model selection. The result suggested that age and INL thickness were related to the postoperative VA, whereas age and preoperative CRT were significantly associated with the change in VA. In contrast, only SUKIMA was correlated with the postoperative metamorphopsia, whilst age, EIFL and SUKIMA were associated with the improvement in metamorphopsia. Measuring SUKIMA might be useful for predicting postoperative metamorphopsia and the improvement in metamorphopsia in ERM eyes.

Exploring Culturally Responsive Voice Care: Mitigating Disparities by Addressing Implicit Bias
Authors: Morton-Jones Mariah E. , Timmons Sund Lauren
Published: December 2023

Purpose:

Access to voice care is central to improving the quality of life of patients with voice concerns. However, health care access is a dynamic, complex entity involving various factors, including the voice clinician. The purpose of this clinical focus article is to explicate the impactful role speech pathologists and voice clinicians may play in daily clinical practice to promote health equity through mitigating well-documented negative effects of personal implicit biases in health care and providing culturally responsive practices.

Conclusions:

Evidence indicates that implicit bias has a grave impact on daily clinical practice and dialogue. Within the complexity of health care access, a clinician either creates barriers or facilitators that determine the acceptability and approachability of the care offered. Unaddressed implicit bias and lack of culturally responsive practices may reduce the quality of care and ultimately hinder a patient from seeking behavioral voice services. However, intentional practices sought by the clinician and health care team to resolve unconscious biases and promote culturally responsive care throughout the therapeutic process are obtainable, as we collectively strive toward health equity for all patients with voice concerns.
Planet formation around intermediate-mass stars

Published: December 2023

Context. The study of protoplanetary disc evolution and theories of planet formation has predominantly concentrated on solar- (and low-) mass stars since they host the majority of confirmed exoplanets. Nevertheless, the confirmation of numerous planets orbiting stars more massive than the Sun (up to ~3 M⊙) has sparked considerable interest in understanding the mechanisms involved in their formation, and thus in the evolution of their hosting protoplanetary discs.

Aims. We aim to improve our knowledge of the evolution of the gaseous component of protoplanetary discs around intermediate-mass stars and to set the stage for future studies of planet formation around them.

Methods. We study the long-term evolution of protoplanetary discs affected by viscous accretion and photoevaporation by X-ray and far-ultraviolet (FUV) photons from the central star around stars in the range of 1–3 M⊙, considering the effects of stellar evolution and solving the vertical structure equations of the disc. We explore the effect of different values of the viscosity parameter and the initial mass of the disc.

Results. We find that the evolutionary pathway of protoplanetary disc dispersal due to photoevaporation depends on the stellar mass. Our simulations reveal four distinct evolutionary pathways for the gas component not reported before that are a consequence of stellar evolution and that likely have a substantial impact on the dust evolution, and thus on planet formation. As the stellar mass increases from one solar mass to ~1.5–2 M⊙, the evolution of the disc changes from the conventional inside-out clearing, in which X-ray photoevaporation generates inner holes, to a homogeneous disc evolution scenario where both inner and outer discs formed after a gap is opened by photoevaporation vanish over a similar timescale. As the stellar mass continues to increase, reaching ~2–3 M⊙, we identify a distinct pathway that we refer to as revenant disc evolution. In this scenario, the inner and outer discs reconnect after the gap opened. For the largest masses, we observe outside-in disc dispersal, in which the outer disc dissipates first due to a stronger FUV photoevaporation rate. Revenant disc evolution stands out as it is capable of extending the disc lifespan. Otherwise, the disc dispersal timescale decreases with increasing stellar mass except for low-viscosity discs.

Published: December 2023

Jawa Tengah is one of the provinces in Indonesia which has high agricultural productivity. That way, it is necessary to carry out an analysis of the carrying capacity of agricultural land in Jawa Tengah Province in 2022. The method used to calculate population pressure and the carrying capacity of agricultural land is the Soemarwoto method which is suitable for local conditions and can assess the factors that affect the level of carrying capacity of land in an area. Jawa Tengah Province has a carrying capacity of agricultural land of 1.43. The value of population pressure in Jawa Tengah Province with a dominance of less than 1 indicates that districts/cities in Jawa Tengah Province are dominated by the carrying capacity of high agricultural land. The high rate of population growth and not accompanied by an area of land capable of supporting the needs of the population can be a threat to the availability of sustainable agricultural land.

Oil palm plantations are undoubtedly recognized as a significant contributor to economic development in Indonesia. However, uncontrolled expansion of oil palm cultivation presents challenges due to its potential negative consequences on the environment and society. This study aims to assess the distribution of oil palm plantations and their suitability with spatial planning in the Aceh Province, Indonesia. We obtained spatial data on plantations from official authorities, which underwent an extensive inventory process during the year 2021. The total area of oil palm plantations in Aceh was reported at 706,943.87 ha, primarily concentrated in the eastern and western lowland areas of Aceh mainland. Through spatial analysis, we identified that approximately 40% of the oil palm plantations are located in areas where plantation development should not be permitted according to existing spatial planning regulations. This study provides important information for land use management in Aceh and offers policy recommendations to promote sustainable oil palm cultivation practices.

Published: December 2023

The Petungkriyono forest is one of the few remnant tropical forests on the island of Java, particularly in Central Java. This forest is known for its high conservation value due to its abundance of biodiversity, particularly the endangered Javan gibbon or Owa Jawa (Hylobates moloch). The Petungkriyono people, on the other hand, rely on upland agriculture and cultivation on steep slopes as a means of subsistence, which poses a threat to the Petungkriyono forest. This paper aims to formulate the direction of the community land use at the habitat of Javanese gibbon at Petungkriyono. The method used the Spatial Multi-Criteria Analysis (SMCA). SMCA was applied to create the initial model of the zoning description of sustainable land use in Petungkriyono. The SMCA analysis process includes goal setting and conceptualization, data collection, analysis, field ground checks, and Focus Group Discussions (FGD) with the community and related parties. The result showed that considering the massive changes of land use at Petungkriyono almost 70% of the area is formulated for perservation and protection to support the conservation of Javan gibbon.

A comparison and insight into the concept of family education in the context of virtue in the masterpieces of pre-school education -- Selected Masterpieces of Preschool Education
Authors: Guan Yuying
Published: December 2023

In contemporary society, a prevalent trend exists whereby parents excessively indulge their children from an early age, delegating the responsibility of education to schools and teachers. This article provides a comprehensive analysis of the similarities and differences between the concepts of home education proposed by Rousseau, Locke, and Comenius, specifically regarding the cultivation of virtue. All three educators emphasize the significance of early education, advocating for home-based education while opposing the reliance on institutional schooling. Furthermore, they collectively recognize the critical role parents play in the moral development of young children and stress the importance of virtue education. Nevertheless, disparities arise in terms of the educational objectives, principles of virtue formation, goals of education, and educational approaches employed by each of these theorists. Consequently, the article asserts the necessity of integrating family education with formal schooling in a harmonious manner. The article posits that these educational perspectives hold profound insights for contemporary family education and offer solutions to current challenges in this domain. Furthermore, it presents strategies and recommendations for parents, urging them to revise their educational mindset, acknowledge their own significance, confront prevailing issues in family education, implement appropriate family education practices, prioritize the holistic development of their children, and help them adapt to societal challenges.

Authors: Xing Siyuan
Published: December 2023

The development of the Internet has had a major impact on this generation of young people. The rise of online media has led to an increasing number of lending product companies seeing opportunities to manipulate the psychological accounts of university students, using tactics such as the payment segregation effect so that they lose sight of the actual value of money and engage in irrational spending behavior. The immature consumption concept of university students makes them more susceptible to the influence of these loan products. The article analyses the consumption behavior of university students at home and abroad through behavioral economics theories, explores the basic influence of lending products on university students’ consumption and various promotional effects and consumption inducements, and proposes countermeasures and suggestions for solutions.

Exploring Adaptive Learning of English as a Foreign Language from the Perspective of Semiotics
Authors: Chen Xinyu
Published: December 2023

Both adaptive learning and semiotics play crucial roles in learning English as a foreign language. This paper reviews adaptive learning and semiotics, respectively, by analyzing the technical support and function of adaptive learning, as well as the concept of semiotics. Then, this paper further explores the relationship between the two, finding out that adaptive learning is an embodiment of semiotics, and semiotics is a mediator in adaptive learning. Among a number of applications of adaptive learning, the author chooses one of the representative applications and analyzes its strengths and weaknesses. Since there are scant articles that cover adaptive learning and semiotics and focus on learning English as a foreign language at the same time, this paper aims to demonstrate the significance of linking the two aspects with foreign language learning and provide practical pedagogical implications to language teachers.

Modern Significance of Liang Shuming’s Rural Education Theory and Practice
Authors: Jiang Chunlan
Published: December 2023

As an innovative form of rural education, Liang Shuming’s theory and practice of rural education has far-reaching significance for the modernization of Chinese rural education and the improvement of the comprehensive quality of rural students. However, current education is facing the problem of utilitarianization of education. This paper first introduces Liang Shuming’s life background and ideological system and the framework of the core ideas of the rural education theory proposed by Liang Shuming, and then discusses Liang Shuming’s rural education theory and practice, i.e., vitalized education. At present, the rate of compulsory education in rural areas is only 79.1% and the rate of high school education is only 32.5%, so the level and quality of education need to be improved. The modern significance of Liang Shuming’s rural education theory and practice in rural education not only lies in the enrichment of educational contents and methods, but also in the promotion of rural economic, social and cultural development and the improvement of rural education quality and level. To this end, we should learn from Liang Shuming’s theory of rural education to enhance the level of rural education and to realize the "life-giving" educational practice of promoting students’ human growth, moral development and spiritual ascension. This paper argues that in the current rural education, the school level should face the growth of students’ lives, consciously care for their lives, and guide them to deepen their own lives; in the practice of education and teaching, it should respect students’ individual lives, build a platform for students’ independent innovation, and nurture students’ spiritual lives with classical Chinese traditional culture, so as to promote the progress of rural education.
