The effect of coronary stent policies on the risk of percutaneous coronary intervention among acute coronary syndrome patients in Shanghai: Real-world evidence
Authors: Shao Zhenyi , Lu Dongzhe , Wang Yue , Xue Di
Published: April 2024

Objective

This study aimed to analyze the effect of coronary stent policies implemented in Shanghai on the risk of percutaneous coronary intervention (PCI) in acute coronary syndrome (ACS) inpatients based on real-world data.

Methods

Two retrospective cohorts of inpatients with a first diagnosis of ACS who had undergone PCI for the first time in the previous year in Shanghai hospitals were examined (one for the postpolicy period and the other for the prepolicy period). χ2 tests were used to compare categorical variables between the two cohorts. Single- and multivariate Cox proportional hazards models were used to compare the risk of major adverse cardiovascular events (MACEs) between the two cohorts.

Results

A total of 31,760 ACS patients were included in this study. The proportion of ACS inpatients who had at least one bid-winning stent and 3 or more coronary stents implanted for first-time PCI in the postpolicy cohort was higher than that in the prepolicy cohort (86.52% vs. 55.67% and 6.27% vs. 4.39%, respectively; all p values < 0.0001). The single- and multivariate Cox proportional hazards models revealed that the unadjusted and adjusted hazard ratios for MACEs at 1 year after PCI for the postpolicy cohort relative to the prepolicy cohort were 0.869 (P<0.0001) and 0.814 (P = 0.0007), respectively.

Conclusions

The implementation of coronary stent policies changed coronary stent utilization but had no significant adverse effects on the risk of PCI among ACS patients in Shanghai in the short term. However, the reasons for changes in the number of coronary stents implanted should be analyzed and addressed in the future.

Published: March 2024

Background

With half a female population, empowering women can be a key factor in our country’s global advancement. Focusing on household decision-making and attitudes toward wife beating, our study addresses the dearth of research exploring how different socio-economic and demographic factors associated with women’s empowerment evolve over the past decade in Bangladesh (from BDHS 2007 to BDHS 2017–18).

Methods

Data from four waves of Bangladesh Demographic and Health Survey (BDHS, 2007 to BDHS, 2017–18) were used in this study. We put forth two domains—household decision-making and attitudes toward domestic violence—to assess women’s empowerment. Principal component analysis (PCA) was employed to create women’s empowerment index. To assess the unadjusted association between the selected covariates and women’s empowerment, Pearson Chi-square test and ANOVA F test have been used, while adjusted association has been analyzed through proportional odds model (POM).

Results

In BDHS 2017–18, women from urban areas experienced ‘high’ empowerment than women in rural areas (56.08% vs. 45.69%). A notable change has been observed in the distribution of women’s empowerment index by education over the survey years. Findings also showed that in all the survey years, division, place of residence, education level, number of living children, media exposure, wealth index, working status, and relationship with household head have been found to have significant association with women’s empowerment index. For instance, women who completed secondary education in 2007, 2011, 2014, and 2017–18, respectively have 14.4%, 31.8%, 24.6%, and 39.6% higher odds of having empowerment compared to those who were uneducated. Further, age at first marriage, spousal age gap, NGO membership etc. emerged as a contributing factor in specific survey years.

Conclusion

Our study affirmed that, over a ten-year period, women were more likely to protest against physical violence and to participate in various decision-making regarding their personal and social life. Empowerment is notably higher among women in urban residents, those with secondary education, 1–2 children, media exposure, and employment. Policy recommendations should emphasize targeted measures to raise awareness and empower uneducated, unemployed, economically disadvantaged, and physically oppressed women.

Published: April 2024

The study aimed to record blooming episodes of the dinoflagellate Ceratium furcoides (Levander) Langhans 1925 and the cyanobacterium Cylindrospermopsis raciboskii (Woloszynska) Seenayya & Subba Raju  in some areas of the São Francisco River Basin, Northeast region of Brazil. Water collections for determination of nutrients, chlorophyll a and phytoplankton density were carried out in the surface layer were collected from May/2015 to December/2016, in seven stations located in the counties of Delmiro Gouveia, Piranhas (Alagoas) and Paulo Afonso (Bahia). The determination of density (cell.mL-1) was performed in an inverted microscope (Zeiss Axiovert). During the study, the average water temperature varied between 26,38 ºC and 30.70 ºC, the pH remained alkaline, the dissolved oxygen contents were between 3.99mg.L-1 and 17.57 mg.L-1, the turbidity varied between 0.21UNT and 26.4 UNT. The maximum value for nitrate was 509.16 µg.L-1 and for total phosphorus was 92.46 µm.L-1. In May 2015, dark stains were visibly observed in some parts of the São Francisco River. These spots were caused by the accumulation of the dinoflagellate Ceratium furcoides. The bloom started in May 2015 with a maximum density of 5,600 cel.mL-1 (Biovolume 112.80µm3.L-1), decreasing considerably in the subsequent months (June, July and November) with densities below 260 cel.mL-1 ( Biovolume 5.24µm3.L-1). In February 2016 it reached another peak with a maximum density of 5,470 cell.mL-1 (Biovolume 113.97µm3.L-1) declining again in June, August and December/2016, with densities below 140 cell.mL-1 (Biovolume 2.92µm3.L-1). The highest density C. raciboskii was observed in June/2016, with 198,000 cell.mL-1 (Biovolume 884.31µm3.L-1). C. furcoides blooms are normally not toxic, whereas C. raciboskii is considered toxic. These microalgae have harmful effects on the entire aquatic community, affecting the balance of the ecosystem. The record of blooms of this species is relevant, as it provides important information about its distribution and dispersion in Brazilian aquatic systems.

Umbu physicochemical quality, diversity in the Caatinga biome and promising genotypes for consumption
Authors: Tonetto de Freitas Sergio
Published: April 2024

Umbu (Spondias tuberosa Arruda) is a wild fruit species distributed all over the Caatinga biome in the Northeast of Brazil. The objective of this study was to analyze the physicochemical quality variability of umbu genotypes in the Caatinga biome, and to identify the most promising ones for fresh fruit consumption, processing industry and breeding programs. The fruit of 69 umbu genotypes were harvested at the maturity stage known as swollen, presenting full size and beginning of softening. The plants were cultivated in the umbu germplasm bank (UGB) at the Brazilian Agricultural Research Corporation, Embrapa, Petrolina, PE, Brazil. Each genotype was characterized by the global position system (GPS) coordinates to understand the distribution of fruit physicochemical quality in different regions in the Caatinga biome. According to the results, fruit physicochemical quality, such as mass, soluble solids (SS), titratable acidity (TA), and SS/TA ratio are homogeneously distributed all over the Caatinga biome. However, there were three main genotype groups, one characterized by higher fruit mass (52, 55, 57, 60, 65, and 68), other by higher SS (08, 09, 11, 20, 38, 41, and 62), and another by lower AT (02, 03, 07, 08, 16, 24, 27, and 51). Umbu genotypes with the highest mass and SS content can be used for commercial production in order to obtain fruit with desirable trait for the market. In addition, genotypes from all three groups can be used in breeding programs to obtain new genotypes with all desirable traits for fresh fruit consumption and processing industry.

Authors: Sanginov A. J. , Isakov I. D. , Akhmetyanov Sh. A. , Peleganchuk A. V.
Published: April 2024

Objective. To analyze the information on spontaneous resorption of lumbar disc herniation.

Material and Methods. A non-systematic review of 37 publications on resorption of disc herniation was conducted. The data on the timing, mechanisms and predictors of regression of lumbar disc herniation were summarized. A clinical case is presented illustrating the resorption of a herniated L4–L5 intervertebral disc over 8 months.

Results. The frequency and timing of resorption of lumbar disc herniation vary depending on the number of patients, follow-up period, the type and nature of the hernial bulging, and other characteristics of patients. The results of meta-analyses indicate that the average period of spontaneous resorption of lumbar disc herniation is more than 6 months. The main theories of spontaneous resorption of lumbar disc herniation are the dehydration theory, the mechanical theory, and mechanisms associated with inflammatory processes and neovascularization. Currently, predictors of disc herniation resorption include the type and size of the hernia, follow-up period, Modic changes, etc. Existing data on the timing, mechanisms and predictors of resorption of lumbar disc herniation are insufficient to improve treatment tactics for this category of patients.

Conclusion. Herniated lumbar intervertebral discs tend to undergo spontaneous regression which, however, is not observed in all patients. The mechanisms of resorption can be different, and the fact of resorption itself can occur in different types of hernia with different frequencies. An analysis of large data sets is necessary to more accurately determine the timing and predictors of resorption of lumbar disc hernias.

An analysis of hybrid impulsive prey-predator-mutualist system on nonuniform time domains
Authors: Kumar Anil , Malik Muslim
Published: April 2024

In this work, we propose a hybrid impulsive prey-predator-mutualist model on nonuniform time domains. We have investigated the permanence/persistence results for the proposed model using the comparison theorems of impulsive differential equations and some dynamic inequality on the nonuniform time domains. In addition, we have established certain necessary requirements for the uniform asymptotic stability of the almost periodic solution and global attractivity of the proposed model. Furthermore, we provide several numerical examples on nonuniform time domains with computer simulation to demonstrate the viability of the results of the acquired analytical work.
Reconstructing Late Neolithic animal management practices at Kangjia, North China, using microfossil analysis of dental calculus
Authors: Wang Jiajing , Liu Li , Qin Xiaoli
Published: April 2024

Examination of plant microfossils (phytoliths and starch granules) preserved in dental calculus allows for the direct identification of some components of prehistoric diets. In this article, the authors present the results of microfossil analysis of dental calculus from wild and domestic animals at the Late Neolithic site of Kangjia in the Central Plains, an area critical in the emergence of early Chinese states. Consumption of cooked plant foods by domestic pigs and dogs, and of domestic crops by wild animals, at this site hints, the authors argue, at an interdependent relationship between animal management, agricultural production and ritual practices that contributed to the political transformations of Late Neolithic China.
Traumatized and Traumatizing: Understanding Clerical Abuse and Dysfunction Through the Lens of Bowenian Systemic Family Therapy
Authors: Skinner Christine Way , Buhagar Desmond C.
Published: April 2024

This article explores the phenomenology of clerical abuse and dysfunction within the Catholic Church from the standpoint of the systemic family therapy of Murray Bowen, MD (1913-1990). While intergenerational systems theory and thinking have been well understood in terms of one's family of origin, this knowledge has rarely been applied to the context of Catholic and other priests within their ecclesial communities and the wider institutional Church. The article examines the relationship between the Church's call to reform and heal ecclesial structures and persons while presenting various intervention strategies such as the need for greater self-differentiation and individuation among them. The primary goal is the need to restore emotional homeostasis and holistic well-being to traumatized individuals and groups.

This project and the associated tasks emerged from the most recent Strategic Planning Member Survey. This member survey is completed every 2 years to gauge the needs and interests of our members. The CPA Board of Directors assumes the mission outlined in the member survey, which honors the vision of the founding members of CPA. This article explores the drafting of the CPA Ethics Code, which is the fruit of the Board's mission to respond to and honor the voice of membership and the mission established by its founding members. So you may ask, what led to the development of the first ever CPA Ethics Code?
Introduction
Authors: Baars Suzanne
Published: April 2024

It is a privilege to be able to introduce the readers of Integratus to the life and work of my father, Catholic psychiatrist Conrad Baars. A survivor of Buchenwald Concentration Camp, he became disillusioned with the secular Freudian approach to therapeutic intervention. Through the hand of Providence, he was introduced to the work of Dr. Anna Terruwe, which changed the trajectory of his life and career. Terruwe, a Dutch Catholic psychiatrist, had been successful in pioneering the rational psychology of St. Thomas Aquinas as the foundation for her work with clients with obsessive compulsive symptoms. In addition, she identified a syndrome in adults caused by a deprivation of love in childhood. Terruwe realized that these persons needed the remedy of someone's receptive, affective presence, which she called affirmation. She observed that contrary to some of the more active treatments, it was crucial to simply be with rather than do much with these persons.
The Impact of Anna Terruwe on the Work of Conrad Baars
Authors: Mazzone Jeff
Published: April 2024

In his autobiography Doctor of the Heart, Conrad Baars (1996) recounted his desire to leave the profession of psychiatry until he discovered the Dutch neuropsychiatrist Anna Terruwe through her writings on Thomistic rational psychology in conceptualizing, treating, and preventing neurosis. He immediately began a partnership with her that continued until his death in 1981. Baars (1982) acknowledged that before discovering Terruwe's work, he did not believe he was “getting anywhere in bringing about true healing” (p. 347). He named Terruwe the discoverer of deprivation neuroses and attributed to her their treatment models for several types of repressive neurosis (Baars, 1959, 1960). An exploration of the legacy of Baars therefore benefits from understanding Terruwe's collaboration with him and her contributions to psychiatry grounded in her philosophical and theological understanding of the human person (Baars, 1981). This article introduces Terruwe, her relationship to Baars, and her theories of neurosis and affirmation that Terruwe and Baars applied to their treatment of individuals, married people, consecrated religious, and priests. Because affirmation is a concept of Terruwe's that Baars widely promoted in the United States and with which he is often associated today, this article offers a detailed summary of her book The Abode of Love in which she formulates the concept of affirmation through a reflection on the meaning, operation, and significance of human love as fundamental for happiness in general, in marriage, and in the priesthood (Ware, 1970).
The Loving Experience of the Therapeutic Relationship as a Factor in Affective Maturation in Adults
Authors: Calatrava Maria , Zapata Ricardo
Published: April 2024

This analysis aims to clarify our hypothesis on the role of love experience as a factor of emotional maturation in adults. Affective experiences during childhood may influence adult self-esteem and sense of worth, as well as affective maturation and the capacity to love. Positive affective relationships, such as therapeutic ones, have the potential to heal entrenched negative emotions such as low self-esteem, and thereby foster confidence and joy. However, love alone does not always overcome the feeling of unworthiness that results from a deeper negative self-evaluation. Similarly, as Conrad Baars and Anna Terruwe elucidate, this sense of unworthiness often stems from early emotional wounds and unmet needs, which necessitate a healing journey beyond the realm of love alone. From the perspective of Baars's theory, integrated psychology can explain how for the person to develop a transcendental love proper to the affectively mature person, it is essential that the therapist helps the clients to (a) identify and heal affective deficiencies in the more immature stages of love, including the strengthening of self-esteem, and (b) promote psycho-spiritual integration, helping the clients to discover their personal worth and the meaning of their existence.
Experimental use of self-affirmation to manage self-concept threat in a simulated intrusive thought paradigm
Authors: Wright Edward C. , Riskind John H.
Published: April 2024

Introduction: Based on the commonality in cognitive clinical theories of OCD and cognitive dissonance theory regarding threat to self (Wright & Riskind, 2021), this preliminary study investigated whether (1) OCD-related distress catalyzed by ego-dystonic intrusive unwanted thoughts is akin to cognitive dissonance, and (2) distress and negative appraisals of the simulated intrusive thoughts can be alleviated by a values-based self-affirmation exercise developed in the dissonance literature. Methods: Nonclinical college students (N = 93) were presented with a simulated intrusive thought induction. After rating their distress from writing the simulated intrusion, they were randomly assigned to one of four conditions: neutralization used in the clinical literature, a values-based self-affirmation task, a combination of neutralization followed by self-affirmation, or a control condition. Results: The results revealed that the group that combined a neutralizing exercise followed by a self-affirmation exercise displayed a significantly greater decrease in dissonance-like distress and negative appraisals of the simulated intrusion than the other three groups. The groups that received self-affirmation alone or neutralization alone did not appear to reduce distress on their own. The combined group and other groups did not show rebound distress. Discussion: These novel analogue study findings help to bring cognitive clinical models of OCD and cognitive dissonance theory closer together. Moreover, they introduce the possibility that self-affirmation procedures could provide useful secondary ways to augment current OCD treatment protocols.

Authors: Santoso Heri Budi , Krisdianto Krisdianto , Yunita Rizmi
Published: April 2024

This study investigated iron (Fe) accumulation in South Kalimantan's coastal swamp wetlands ecosystem, utilizing giant mudskipper fish as indicators of heavy metal pollution. By analyzing Fe levels in water, sediment, and fish organs over time, insights into its effects on the environment and human health were gained. Furthermore, through Atomic Absorption Spectrometry, Fe concentrations in Kuala Lupak's coastal wetland were measured, revealing significant correlations between Fe levels in water, sediment, and fish tissues. These results enhance our understanding and inform better management strategies. Anthropogenic and natural sources contribute to the accumulation of heavy metals, particularly Fe, with anthropogenic pollution being the most dominant. This study presented the escalating concentrations of Fe within the Kuala Lupak estuary and raised concerns regarding the ecological and human health implications. Continuous monitoring, source identification, public awareness, regulations, remediation, and long-term exploration are essential for addressing heavy metal pollution and its ecological impact. Therefore, valuable insights are provided for environmental management and conservation efforts.

Authors: Maulana Amsar , Harianti Mimien , Prasetyo Teguh Budi , Herviyanti Herviyanti
Published: April 2024

Optimizing the potential utilization of low-rank coal, such as sub-bituminous coal (SC), can improve and maintain soil quality and productivity through amelioration technology. This potential is especially in controlling heavy metals such as Hg. This study aimed to examine the geochemistry of SC and the adsorption mechanism of Hg with SC through an adsorption isotherm model approach developed for experimental equilibrium. The geochemical of SC has an atomic composition of C (43.60%), O (40.64%), N (11.96%), Si (1.57%), Al (1.06%), Ca (0.92%), Mg (0.14%) and K (0.11%) and oxide composition dominated by SiO2 (57.07%), as well as O-H and N-H functional groups, C-H C-H, C=C-H, C=O, and C=C-H and minerals (quartz, magnetite, mica and muscovite). Characteristics of SC have a proximate composition (16.99% moisture, 97.81% volatile matter, 69.63% ash, and 28.19% fixed carbon) and chemical properties of pH, EC, CEC, OC, and total N (5.23, 1.38 dS m-1, 35.33 cmol(+) kg-1, 9.81% C,  and 0.16% N). The adsorption capacity and coefficient of Hg2+ by SC were 304.32 mg g-1 and 78.67 L kg-1 at pH 1.26 and Hg2+ concentration 100 mg L-1 with a removal efficiency of 76.08%. Hg2+ adsorption isotherms occurred in Langmuir (RL = 0.97 and R² = 1)>Freundlich (1/n = 1.05 and R² = 0.9999) models. The application of 40 t SC ha-1 on ex-gold mining soil contaminated with Hg significantly decreased the total Hg in the soil by 2.50 mg kg-1 and a removal efficiency of 36.37% with increased pH H2O (0.35), OC (0.041% C), and CEC 2.14 cmol(+) kg-1, compared to control.
Peri-urban forests: an exploratory study of users' recreational activities: The case of the El Meridj-Est recreational forest in Constantine, Algeria
Authors: Bouttaba Chourouk , Nouibat Brahim , Benmechiche Meriem
Published: April 2024

Peri-urban forests are wooded areas under the influence of urbanization and are becoming increasingly attractive as recreational areas for urban populations. This study focused specifically on the El Meridj-Est recreational forest, located in Constantine, the capital of eastern Algeria. This study selected this forest as the main case study because of its distinction as the region's most frequented woodland site. This research aimed to understand the practices of 350 users of this forest and to identify the determining factors behind the high affluence at El Meridj. This study also examined their individual and family perceptions, expectations, and concerns, adopting a methodological approach combining detailed qualitative and quantitative social survey techniques. This study fills a research gap in the field of peri-urban green space management with regard to social interactions and recreational activities in these spaces. It also highlights the importance of taking local specificities into account when studying recreational spaces. These results, potentially generalizable to other similar geographical and cultural contexts, offer practical perspectives for the management and conservation of peri-urban forests while minimizing the negative impacts of anthropogenic pressures leading to the degradation of these natural environments.

Published: April 2024

Acid Mine Drainage (AMD) contains Fe(II) and Mn(II) metals, which can cause environmental pollution. This research aimed to investigate the potency of activated carbon made from coal as an adsorbent in AMD treatment. The carbon was made of coal and activated with H3PO4 in a weight ratio of 40%, 800 °C for 120 minutes while supplying 1.5 L/min of nitrogen during the carbonization process. The result shows that BET surface area, total pore volume, and iodine number were 296.4 m2/g, 0.156 cc/g, and 1205 mg/g, respectively. The surface contained many fractures, channels, and big holes, as evidenced by the FT-IR and SEM investigations, and it also had acidic surface functional groups. The optimum contact time adsorption for AMD treatment was 30 minutes, and the first concentration of Fe(II) and Mn(II) metals affected the adsorption. The optimum removal of Fe(II) in AMD treatment was 95.27% at an initial concentration of 3.51 ppm, while the optimum removal of Mn(II) was 99.82% at an initial concentration of 5.71 ppm. This activated carbon has a considerable potency to be used as the adsorbent in AMD treatment to reduce Fe(II) and Mn(II) levels.

Chara corallina is a freshwater macroalgae found in aquatic-terrestrial boundary environments. Their cellulose fibers have a crystallinity and biosynthesis similar to those of terrestrial plants. The algal nanocellulose (NC) was prepared through a series of chemical treatments, including alkaline, bleaching, grinding, and acid hydrolysis. The X-ray diffraction (XRD) crystallinity index of nanocellulose was 85.64%. The cellulose nanocrystals are seen in the form of nanorods, and the specific surface area of the sample of NC found was 5.823 m2g-1. The study aimed to test the effectiveness of a nanocellulose composite membrane in removing heavy metal ions, specifically cadmium (Cd), nickel (Ni), and lead (Pb) ions, from an aqueous solution. A vacuum filtration unit was used for the experiment, where up to five filter layers of composite membranes were examined for their ability to remove heavy metal ions. The results showed that the highest removal rates of Cd2+, Ni2+, and Pb2+ ions were 98.20%, 95.15%, and 93.80%, respectively, when using five layers of membranes of NC with the adsorbent dose set at 20 ppm. Cellulose and its derivatives are essential in sustainable technology for wastewater treatment, as they demonstrate exceptional performance in removing various types of pollutants, including heavy metals, dyes, and other pollutants. Cellulose is preferred due to its low cost, biodegradability, eco-friendliness, and simple surface modification.

On September 28, 2018, a 7.5 Richter magnitude earthquake struck the Palu City neighborhood of Petobo. The tectonic activity along the Palu-Koro fault generated this earthquake, which resulted in soil liquefaction. The purpose of this study is to use microtremor measurements at 33 distinct places to investigate the properties of the soil layer after liquefaction. The obtained data was then evaluated utilizing Horizontal to Vertical Spectral Ratio (HVSR) methodologies such as Ground Shear Strength (GSS), amplification factor, and vulnerability index to determine the soil layer's properties and susceptibility. The dominant frequency ranges from 0.19 to 4.75 Hz, while the dominant period ranges from 0.21 to 5.17 seconds, according to the measurement results. According to these measurements, the silt layer varies between 5 and 30 m. GSS values in the 10-4 to 10-2 range indicate that soil cracking, subsidence, liquefaction, landslides, and compaction are likely. The soil vulnerability and amplification index values range from 2.36 to 4.37, respectively. These values show the potential level of danger, which might be low, medium, high, or extremely high. Peak ground acceleration varied from 299.52 to 301.52 gals, suggesting high to extremely high danger levels. The microzonation map created for this study is considered to be a useful resource for training disaster mitigation approaches and facilitating infrastructure development planning in the region.

Farmers in Ethiopia and other sub-Saharan African countries often implement various agricultural land management (ALM) practices to mitigate the negative impact of land degradation, increase crop yield, improve income, and safeguard the security of food. Despite the widespread use of these measures, their effect on crop productivity and related income has received relatively little attention in research, particularly in the context of mixed farming systems. The objective of this study was to assess the effects of ALM practices on crop production and household income in southern Ethiopia. Data was gathered from 423 sampled respondents, which included adopters and non-adopters of ALM practices. This study adopted multistage sampling to gather the data through a survey questionnaire. This study’s findings reveal that ALM strategies have a considerable impact on crop productivity and the incomes of farm households (p<0.05). Moreover, the adoption of integrated physical and biological intervention practices for longer durations resulted in a steady increase in both crop productivity and household incomes. Furthermore, analysis of the effect of long-term treatment indicates that farms show a significant and increasing marginal benefit to production after six years of intervention. These findings imply that integrating ALM practices and maintaining them for an extended period (i.e., 10 years) will help to increase crop productivity and household incomes. Hence, adopting a wider range of physical and biological ALM measures and ensuring their continual adoption are key strategies for improving crop production and increasing household income. This strategy will have significant policy implications and provide a solid foundation for sustainable agricultural development.

In 2014, Kelud, an active volcano in East Java, ejected ashes (hereafter termed KA; Kelud ash) that reportedly reached as far as Central Java and the Special Region of Yogyakarta (DIY). The KA deposits are observable in, among others, the coastal sand dune area in Parangtritis. Due to the active aeolian process, the KA layers can be found at different depths five years after the eruption. Thus, the KA can be used as a marker of the post-2014 aeolian activities at the Parangtritis dune, which was once classified as a degraded land and later recognized as a coastal geosite, ultimately allowing us to calculate the volume and sand transport rate. The research surveys performed at 25 points discovered volcanic ash layers at 1 cm to 26 cm below the surface. At some observed points, the ash deposits were found on the surface and continuously transported. This research observed an area of 60,000 m2 with an average of 8.5 cm thick sand layers lying above the KA layer. Based on the calculation, the total volume of the transported sand at the Parangtritis sand dune from 2014 to 2019 was approximately 5,100 m3. This volume is considerably small owing to various obstacles in the transport zones. Based on the five-year dynamic of the sand dune, this study suggested that restoration needs to be conducted immediately particularly in eliminating vegetation barriers to maintain the sediment balance (erosion-transport-sedimentation) of the coastal sand dune area.

When cultivating medicinal plants, the use of chemical substances such as pesticides and chemical fertilizers should be avoided, as these can be contaminated with hazardous substances. Bio-fertilizers are a good alternative for growing herbs, as they are produced from organic materials that contain fewer hazardous substances. The aim of this study was to investigate the effects of different bio-fertilizers on growth, yield, andrographolide content, nutrient accumulation, and different pigments in green chiretta. In addition, the effectiveness of bio-fertilizers on the convertible phosphorus content in the soil was investigated. The experimental design was a completely randomized design (CRD) with four treatments and four replicates. The details of the experiment were 1) control (no bio-fertilizer), 2) phosphate-solubilizing microorganisms (PSMs), 3) plant growth promoter, and 4) mycorrhiza. The findings revealed that the application of PSMs provided the highest leaf dry weight (yield) of green chiretta (20.8±3.58 g/plant). This treatment also gave the highest chlorophyll a, b and total chlorophyll content (699±70, 178±24, 880±94 mg/sqm, respectively) and andrographolide yield (0.38±0.06 g/plant). Regarding the phosphorus content in the soil, the PSMs application showed the highest available phosphorus and the highest phosphorus activation coefficient (PAC) in the soil, namely 52.0±4.76 mg/kg and 4.22±0.32 percent, respectively. These results indicate that the use of PSMs as a bio-fertilizer is most suitable for the cultivation of green chiretta, especially when this plant grows on acid sulfate soils.

Biochar and Tithonia compost are alternative materials used to ameliorate soil properties. The application of these two types of ameliorants in ex-coal mining areas aims to improve the physical properties of the soil and its effect on soybean growth and yield. The research was designed in the form of a polybag experiment conducted in a greenhouse. The soil used for this research was taken from the surface layer of ex-coal mining pits. The treatment levels tested consisted of three biochars and four Tithonia composts. Each treatment level was 0, 5, and 10 t biochar ha-1 and 0, 5, 10, and 15 t Tithonia compost ha-1. The research units were arranged in a completely randomized design. The results showed that applying 10 t biochar ha-1 and 15 t Tithonia compost ha-1 decreased soil bulk density, increased total pore space, aggregate stability, and soil water content capacity, and improved soybean growth and yield. The soil physical properties and soybean improvement were not significantly different from those due to the application of 5 t Tithonia compost ha-1.

Maintaining productive farmland necessitates precise crop mapping and identification. While satellite remote sensing makes it possible to generate such maps, there are still issues to resolve, such as how to choose input data and the best classifier algorithm, especially in areas with scarce field data. Accurate assessments of the land used for farming are a crucial part of national food supply and production accounting in many African countries, and to this end, remote sensing tools are being increasingly put to use. The aim of this study was to assess the potentiality of Sentinel-2 to distinguish and discriminate crop species in the study area and constraints on accurately mapping cropping patterns in the winter season in River Nile and Northern State, Sudan. The research utilized Sentinel-2 Normalized Different Vegetation Index (NDVI) at 10 m resolution, unsupervised and supervised classification method with ground sample and accuracy assessment. The results of the study found that the signatures of grain sorghum, wheat, okra, Vicia faba, alfalfa, corn, haricot, onion, potato, tomato, lupine, tree cover, and garlic have clear distinctions, permitting an overall accuracy of 87.38%, with trees cover, onion, wheat, potato, garlic, alfalfa, tomato, lupine and Vicia faba achieving more than 87% accuracy. Major mislabeling problems occurred primarily in irrigated areas for grain sorghum, okra, corn, and haricot, in wooded areas comprised of small parcels of land. The research found that high-resolution temporal images combined with ground data had potential and utility for mapping cropland at the field scale in the winter.

Published: April 2024

Over the past few years, numerous urban areas have been identified in floodplains and coastal regions. These areas should be repurposed as water storage zones to enhance surface water infiltration. The escalating demand for land in flat areas adds complexity to the susceptibility of urban areas to flood hazards. The observation focuses on understanding how land use change influences urban flood susceptibility assessment. Several aspects assumed to have a significant relationship with the flood phenomenon include the impact of land use change, environmental health impact, modification of land typology, explanation of urban flooding, appropriate model for flood-prone assessment, current state of research, appropriate steps in decision-making in susceptibility areas, and challenges of the scenario-based flood-prone mapping model in the future. Additionally, the assessment aspect should consider the impact of land degradation resulting from land use change. Integrated measures are necessary to guide future studies aimed at improving ecological quality and restoring environmental health. The availability of free and open-source datasets facilitates conducting studies to support decision-making both locally and regionally.
