Published: February 2024

Wastewater is a complex matrix consists of varied pollutants namely particulate matter, microorganisms, dissolved solids, biogeochemical species at significant concentrations. Wastewater treatment brings down the concentration of pollutants to permissible levels. The Technology faculty has approximately 1,600 students and approximately 110 academic and non-academic staff members. We have observed that wastewater from the washroom systems, canteens and water used for cleaning activities are directed to the wastewater treatment plant. The study was conducted to determine the quality of generated and treated wastewater when the faculty functions in full capacity. Upon the treatment of wastewater, these are pumped for the garden water supply of the faculty. In this research, parameters like water pH, temperature, turbidity, dissolved oxygen (DO), chemical oxygen demand (COD), conductivity, total suspended solids (TSS) and temporary hardness of water were analyzed for both influent and effluent. The treatment efficiencies COD, DO, TSS and turbidity were recorded 53%, 41%, 96% and 93% respectively after the wastewater is passed through equalization anaerobic tanks, aeration tank, clarifier, chlorination tank, sand filter and carbon filters. The occurrence of an efficient treatment of wastewater can be concluded and it is recommended to be used for general water usage at the faculty gardening activities.

The study aimed to explore the therapeutic potentials of medicinal plants identified and documented indigenous uses of medicinal plants at T.B.Tennakoon Memorial Ayurveda Base Hospital and Study Center, North Matale, Sri Lanka. The study was followed over six months from March 2021 to September. Authorization was granted by the MOIC hospital and during this period the therapeutic effects of medicinal plants were classified among the plants studied. An investigation conducted through direct observation in the field, discussion, and via quessionaire. Collected plant samples and images of plants, herbarium leaves, and botanical plaques, were identified by healers in hospitals and old mounds in the region, and information gathered on medicinal plants was recorded and documented. A total of 130 medicinal plants belonging to 47 families have been identified in the region. Microsoft Excel 2013 version 15.04 was used for data analysis. The most common medicinal plant families are Fabaceae (19%), other more identified medicinal plants are Euphorbiaceae (15%), Rutaceae (10%), and Santalaceae (1%). Some rare medicinal plants have also been reported. According to this study, this area contains rich green floristic diversity, and the plants have grown well in the regional climatic conditions and the natives have used the plants for multiple purposes. Therefore, these medicinal plants are used for various diseases such as Loco-motor disorders, urinary disorders, circulatory disorders, respiratory disorders, nervous disorders, gastrointestinal disorders, skin disorders, gynecological disorders, hormonal disorders, and poisonous bites. These plants, which are used in various diseases and have different therapeutic potentials, are freely harvested in this hospitable region and some plants are also abundant. The conservation of these plant species is essential to improve traditional health practices within the hospital. However, plant breeding and conservation education are used in primary health care, conservation of their diversity, as well as clinical practice, and scientific research.

Published: February 2024

One of the major global trends of the twenty-first century that has a big impact on our lives is urbanization. By 2050, two-thirds of the world's population, who currently make up half of the population are expected to reside in urban regions. The demands of urban environments can lead to greater poverty and environmental degradation such as poor air and water quality, shortages in water supply, waste-disposal issues, and excessive energy consumption will become worse. Additionally, urbanization encourages the invasion of non-native species by reducing the diversity of plant species, making it difficult to plant growth. Some species, however, exhibit signs of resilience to these challenges and are adaptable to the urban environment. Spontaneous Urban Plants (SUP), also known as "weeds" are frequently found in abandoned urban landscapes. They are neglected as unwelcome, unwieldy, and unkempt, but they thrive in environments where most plants cannot grow. They can grow out of cracks in the sidewalks, in the wall of a garbage ditches, or even in a tiny space inside the walls of houses. This research aims to identify the SUP species with ethnomedicinal values in urban environment. This roadside surveys were conducted to identify SUP species with ethnomedicinal values in 10 urban areas in the Galle district between January and July 2020. Open-ended and semi-structured questionnaire was used to interview a total of 37 people including Ayurveda and traditional medical practitioners, community elders and people experts in plants. The acquired data were verified using the Ayurveda authentic books and reputed journals. A total of 50 plant species of 27 families were identified as SUP. Asteraceae and Amaranthaceae and Fabaceae were reported as the most represented families. The most plant species are used to treat gastrointestinal disorders, followed by respiratory disorders and dermatological conditions. However, ethnomedicinal values of these SUP are yet to be revealed.

Sri Lanka is rich in biodiversity and traditional, religious, and cultural practices. However, some of these traditional beliefs could lead to decline of the local biodiversity. Ran-Dotalu (Loxococcus rupicola (Thw.) H. Wendl. & Drude,) is one of the sacred groves among the Buddhists and Buddhism is the major religion followed in Sri Lanka. L. rupicola (Family Arecaceae), is a palm listed as Critically Endangered and Endangered on the global and national red lists respectively. Loxococcus is an endemic genus and Ran-Dotalu is also protected under the Flora and Fauna Protection Ordinance. It confines to rainforests in central highlands of Sri Lanka as small populations on shady rocky outcrops. Therefore, the objective of this study was to explore the religious beliefs, and cultural practices, and document the present state of the wild collection of Ran-Dotalu to identify the threats related to religious activities. Sociocultural data on Ran-Dotalu and its uses in the rituals were collected based on semi-structured questionnaire interviews via formal discussions, telephone conversations, and emails. Out of 114 respondents there were Buddhist priests (n=03), plant collectors (n=07), and users and or worshipers (n=104). Among them 36% were males and 64% were females. According to the results, flowers, seeds, seedlings, and saplings collections were reported from Peak Wilderness sanctuary, Erantha-Gilimale Forest reserve, and Knuckles Forest Reserve. Ran-Dotalu. Flowers were mainly collected for religious activities and rituals (42.3%), medicinal purposes (26.3%), as a substitute for Areca nut (23.6%), and to sell (7.8%). Worshiping with Ran-Dotalu flowers was common at Sri Padasthanaya, Temple of Tooth, Ruwanweliseya and Jayasrima Bhodiya, Saman Devalaya, and Katharagama Devalaya. On average 10-12 flowers were collected by a collector per month and, sold for a price ranging from Rs. 500 to Rs. 5,000. On average 10-15 flowers (per month) were brought to above-mentioned religious places. According to the legends god Sumana-Saman offered Ran-Dotalu flowers to Buddha for establishing Sri Padastanaya. Therefore, worshipers believe that offering Ran-Dotalu flowers is a great act of charity and pays off all sin. The palm recently become a popular ornamental plant (9%) despite its protected status. Around 78% of the respondents were not aware of the conservation status of L. rupicola. Thus, seed production and young generations in the wild populations are in danger. The study suggests that understanding of practices that may threaten local biodiversity and immediate actions are needed to conserve the L. rupicola wild populations.

La democracia mexicana sigue en el horizonte
Authors: Guerrero Anaya Luis José
Published: February 2024

Este artículo trata de reflexionar sobre la construcción de un ethos democrático (Cortina, 2000, p. 267) en México, puesto que no bastó con las alternancias habidas en el gobierno (2000, 2012, 2018). En otras palabras, México no ha alcanzado la democracia, como lo muestran los datos enumerados en el texto. La democracia permanece como un horizonte: deseado, pero no alcanzado. Las tareas pendientes para legitimar completamente la democracia son, además de respetar sus reglas: regresar a la política, alentar los movimientos sociales, renovar los partidos y los sindicatos, repensar y, en su caso, crear nuevos significados comunes, imaginar lo posible, aun cuando lo anterior se haga en medio de las limitaciones implicadas en corregir las ideas que los actores sociales tenemos sobre la realidad.
(Re)imaginar el periodismo inteligente
Authors: López-García Xosé
Published: February 2024

La emergencia de la Inteligencia Artificial (IA) en los procesos comunicativos mediados tecnológicamente no sólo ha abierto nuevos debates en el periodismo sino que ha puesto sobre la mesa, una vez más, su futuro en una sociedad red donde, a pesar de la ubicuidad, la información veraz que circula por los diferentes canales y en todo tipo de formatos representa una pequeña parte de los flujos comunicativos. Tras las alargadas sombras de las turbulencias que han acompañado al periodismo en las primeras olas de transformación digital, la irrupción de la IA en las redacciones anuncia nuevas oportunidades y plantea renovadas amenazas, en un contexto de regulación y de expectación sobre la capacidad para ordenar el nuevo escenario en favor de los ciudadanos. Una revisión analítica de las aportaciones y los temores que suscitan los nuevos desafíos animan el diseño de algunos elementos que impulsan las iniciativas que buscan imaginar un periodismo inteligente. Dado que las máquinas no tienen compromisos firmes con la verdad y la honestidad ni disponen de todas las coordenadas que les señalen la disciplina de la verificación como la esencia del periodismo, apostamos por la inteligencia artificial híbrida, la que combina diferentes algoritmos y técnicas de aprendizaje automático con conocimiento y lógica humana, como una de las mejores vías para la consecución de un periodismo más inteligente –periodismo total que aproveche todas las técnicas y modalidades heredadas y alcanzadas en estos dos siglos– y más humano –más centrado en las personas, para las personas y con las personas–.

The functional basis of agricultural marketing
Authors: KONONENKO Ganna
Published: February 2024

The article is examined key principles, func­tions, systems and methods that allow ensuring market orientation of the production and sales activities of the enterprise, where effective management decisions are based not only on the capabilities of the manufacturer, but also prima­rily the needs of the agro-industrial market, existing and potential needs of consumers and buyers of agricultural products. It was the first time to propose a definition of the functional basis of agricultural marketing – it is a system of organizational, economic, technical, financial and commercial functions of enterprises, united by a synergistic effect, and aimed at optimal and adaptive satisfaction of consumer demand for agricultural products and food security. It has been established that agricultural marketing can be implemented in mechanisms of mutually beneficial exchange between various market subjects, create conditions for identifying con­sumer requirements and determining the possibi­lities of their satisfaction, which will provide an opportunity to study the agricultural market and forecast its dynamics, form demand for the products of this market and stimulate it distribution The main aim of the research is to offer the author’s interpretation of the concept of "agricultural marketing" and to determine of the functional basis of agricultural marketing in the conditions of martial law. The main hypothesis of the research is to prove the effectiveness of the functional basis of agricultural marketing in the conditions of a full-scale invasion of the Russian Federation on the territory of Ukraine. It has been proven that for effective planning and management of agrarian business of the national economy in the conditions of a full-scale invasion, as well as taking into account the existing conditions (alienation of territories, damage and occupation of part of the land), entrepreneurs are forced to effectively and quickly implement agricultural marketing in its economic activity for researching consumer needs, forecasting demand, studying assortment policy and developing a production program, studying channels of goods movement and organizing safe sales.

Authors: Muazzam Zainab , Munir Maryam , Suneel Ivan
Published: February 2024

Past literature has shown that academic procrastination shares a negative association with an internal locus of control and self-variables, including self-esteem, self-regulation and self-efficacy. These self-variables may even have a negative effect on students’ academic performance. The aim of the current study is to explore whether students who have higher creative self-efficacy are less likely to experience academic procrastination. A correlational research design is used. Hence, the current research determines the relationship between academic procrastination, locus of control, and creative self-efficacy in Pakistani undergraduate students. Pearson's Product Moment Coefficient of Correlation is calculated. There are significant correlations between the three variables. Regression analysis indicates that both variables make a significant contribution towards academic procrastination. Results are discussed in light of the literature review.

Authors: Farooqi Muhammad Tahir Khan , Khalid Muhammad Naveed , Shafiq Aima
Published: February 2024

The study aimed to assess the impact of implementing Six Sigma practices on teaching effectiveness. This exploratory research, conducted at the University of Okara, centred on teachers from various departments. Qualitative data was gathered via semi-structured interviews and analyzed using thematic analysis. The findings revealed that faculty members were unintentionally addressing three phases (define, measure, and analyze) of the Six Sigma process due to a lack of awareness. Students were knowledgeable about their educational standards and rights, and their issues were addressed when communicated. However, the remaining two phases (improvement and control) of Six Sigma were neglected by university teachers, with quantity taking precedence over quality. Teachers acquainted with Six Sigma practices demonstrated greater teaching effectiveness. The study recommends raising awareness among teaching staff about Six Sigma practices and ensuring their implementation for better outcomes. Expanding the data collection scope for result triangulation is also suggested.

Self-Tuning PID Controller for Quadcopter using Fuzzy Logic
Authors: Baharuddin A'dilah , Basri Mohd Ariffanan Mohd
Published: February 2024

Tracking has become a necessary feature of a drone. This is due to the demand for drones, especially quadcopters, to be used for activities such as surveillance, monitoring, and filming. It is crucial to ensure the quadcopters perform the tracking with stable flight. Despite the advantages of having VTOL ability and great maneuverability, quadcopters require an effective controller to overcome their under-actuation and instability behavior. Even though a PID controller is commonly used and promising with its simple mechanism, it requires very proper tuning to ensure the stability of the system is not affected. In this paper, a simple Fuzzy algorithm is proposed to be incorporated into a PID controller to form a self-tuning Fuzzy PID controller. The Fuzzy logic controller works as the self-adjuster to the PID parameters. A mathematical model of the DJI Tello quadcopter is derived with position and attitude control loops that are designed to track a variety of trajectories with stable flight. The proposed method uses a simple architecture where the ranges of PID parameters are used as scaling factors for Fuzzy controller outputs. The results of the simulations show the tracking error performance metrics, which are IAE, ISE, and RMSE, are smaller compared to the values of the PID controller. Beyond its impact on quadcopter control, the proposed self-tuning approach holds promise for broader applications in nonlinear systems.
Performance Investigation of Low-Cost Dual-Axis Solar Tracker using Light Dependent Resistor
Authors: Keo Chivorn , Srang Sarot , Seng Rattana
Published: February 2024

To generate power, the solar tracker mechanism can be mounted on a stationary or mobile platform. Moving platforms include boats, ground vehicles, and aerial vehicles. The solar tracker must be a mechanism that can keep the solar panel perpendicular to the direction of the sun at an appropriate level of precision in order to be more effective. Therefore, this research is going to investigate the performance of a low-cost dual-axis solar tracker (parallel mechanism) installed on a moving platform. This work describes the simulation and experiment of a dual-axis solar tracker that is mounted on a rotating support plate with rotational axis. This simulation uses the method of controlling linear actuators to adjust the solar panel perpendicular to the direction of sunlight. Both actuators were controlled by proportional and integral controllers (PI), which will make the system have a faster response time. The tracker is equipped with a type of low-cost sunlight sensor to provide the information for determining the orientation of the sunlight vector with respect to the solar panel. The sunlight sensor was designed and fabricated on our own by adding four light-dependent resistors in the four different quadrants. For the purpose of tracking the sun, the mathematical models of the tracker mechanism, sun sensor, and control architecture are defined. The results of simulation and experiment demonstrate that the tracker control system can follow the sun with some tracking error (about 2 degrees) at its final alignment. In real-time applications, solar trackers can be used on vehicles or boats to adjust solar panels on their surfaces and increase their exposure to sunlight and electrical output.

Published: February 2024

The multiplication of nonlinear loads leads to significant degradation of the energy quality, thus the interconnection network is subject to being polluted by the generation of harmonic components and reactive power, which causes a weakening efficiency, especially for the power factor. In three-phase systems, they can cause imbalances by causing excessive currents at the neutral. This research treats the operation of robust voltage-oriented control (VOC) for a shunt active power filter (SAPF). The main benefit of this technique is to guarantee a decoupled control of the active and reactive input currents, as well as the input reference voltage. To sustain the DC voltage, a robust PI-structure-based antiwindup is inserted to ensure active power control. Besides, a robust phase-locked loop (PLL)-based bandpass multivariable filter (BPMVF) is used to improve the network voltage quality. Furthermore, a space vector modulation (SVM) is designed to replace the conventional one. A sinusoidal network current and unitary power factor are achieved with fewer harmonics. The harmonics have been reduced from 27.98% to 1.55% which respects the IEEE 519-1992 standard. Expanded simulation results obtained from the transient and steady-state have demonstrated the high performance of the suggested control scheme.

Salivary gland botulinum toxin injection is a widely studied therapeutic method for treating sialorrhea. The proper protocol for such treatment modality is an area of interest for researchers. This study set out to assess the success of ultrasound-guided botulinum toxin injections in either the submandibular or combined with parotid salivary glands for children with cerebral palsy suffering from sialorrhea, while also identifying factors that predict a positive treatment outcome. 
Method: This cross-sectional study included 30 children with cerebral palsy who have Sialorrhea. Ultrasound-guided botulinum toxin injections of submandibular salivary glands alone or combined with parotid glands were done. Drooling was evaluated using Drooling Rating Scale, Drooling Impact Scale, and 5-minute Drooling Quotient. Children were followed up weekly for 12 weeks after botulinum toxin injections.
Result: All children showed a significant decline in drooling and sufficient caregivers’ satisfaction for the first 8 weeks after botulinum toxin injections, with gradual worsening of drooling later in 60% of children. Assessment scores were significantly lower in those who received combined parotid and submandibular injections than those who received submandibular gland injections alone. Changes in drooling scores have a significant negative correlation with the severity of motor disabilities.
Conclusion: Submandibular salivary gland injection alone has a satisfactory response in decreasing drooling in children with cerebral palsy. However, a combined injection of both parotid and submandibular salivary glands gives a better response for at least 8 weeks without complications. This study not only addresses the clinical effectiveness of botulinum toxin injections in managing sialorrhea in children with cerebral palsy but also opens avenues for improved dietary strategies.

Causal Relationship Between Ferritin and Neuropsychiatric Disorders: A Two-Sample Mendelian Randomization Study
Authors: Sun Wenxian , Wei Cuibai
Published: February 2024

Background:

Previous observational research has indicated a correlation between ferritin levels and neuropsychiatric disorders, although the causal relationship remains uncertain.

Objective:

The objective of this study was to investigate the potential causal link between plasma ferritin levels and neuropsychiatric disorders.

Methods:

A two-sample Mendelian randomization (MR) study was conducted, wherein genetic instruments associated with ferritin were obtained from a previously published genome-wide association study (GWAS). Summary statistics pertaining to neuropsychiatric disorders were derived from five distinct GWAS datasets. The primary MR analysis employed the inverse variance weighted (IVW) method and was corroborated by additional methods including MR-Egger, weighted median, simple mode, and weighted mode. Sensitivity analyses were employed to identify potential pleiotropy and heterogeneity in the results.

Results:

The fixed effects IVW method revealed a statistically significant causal relationship between plasma ferritin level and the occurrence of Alzheimer’s disease (odds ratio [OR] = 1.06, 95% confidence interval [CI]: 1.00–1.12, p = 0.037), as well as Parkinson’s disease (OR = 1.06, 95% CI: 1.00–1.13, p = 0.041). Various sensitivity analyses were conducted, which demonstrated no substantial heterogeneity or pleiotropy. Conversely, no compelling evidence was found to support a causal association between ferritin and amyotrophic lateral sclerosis, schizophrenia, or major depressive disorder.

Conclusions:

This MR study provides evidence at the genetic level for a causal relationship between plasma ferritin and an increased risk of Alzheimer’s disease and Parkinson’s disease. The exact genetic mechanisms underlying this connection necessitate further investigation.
The Association Between Positive Amyloid-PET and Cognitive Decline Is Not Always Supportive of Alzheimer’s Disease: Suggestions from a Case Report

Published: February 2024

Amyloid-β deposition is the pathological hallmark of both cerebral amyloid angiopathy and Alzheimer’s disease dementia, clinical conditions that can share cognitive decline and positive Amyloid-PET scan. A case is reported involving an 82-year-old Italian female who presented initially a memory deficit, later transient focal neurologic episodes, and finally two symptomatic lobar intracerebral hemorrhages. In light of these events, MRI and PET imaging findings, acquired before cerebral hemorrhages, are reconsidered and discussed, highlighting the utility of Amyloid-PET in supporting an in vivo diagnosis of cerebral amyloid angiopathy.

BACKGROUND: Breast cancer (BC) patients’ diagnosis and management was affected by a global reorganization after the Coronavirus disease 2019 (COVID-19). Our study aimed to assess the impact of the pandemic on the pathological stage of newly diagnosed patients with BC compared to pre-pandemic and to identify predictive factors of tumor advanced stage. METHODS: Pathological records of all consecutive newly operated BC patients between March 2020 and December 2021 were reviewed retrospectively. Clinical and pathological prognostic factors of BC were collected and compared between pre-pandemic and pandemic periods. Then, predictive factors of tumor advanced stage were identified. RESULTS: Of the 225 cases included in the analysis, 98.7% were females and 1.3% were males. The median time from first histological diagnosis to first surgical treatment was enlarged by 42 days with a significant difference between the two periods (p = 0.002). Newly diagnosed BC patients during the COVID-19 pandemic were operated at a more advanced stage (54.1% vs 36.2%, p = 0.007), had a greater lymphovascular invasion (p = 0.002), lymph node metastasis (p = 0.015) and are more commonly of IBC NST histological type (p = 0.005). Moreover, multivariate analyses showed that the pandemic period (AOR = 2.28; p = 0.016) and the lympho-vascular invasion (p < 0.001) were independently associated with advanced stage of tumors. CONCLUSION: Our findings proved an increase in alarming rates of advanced stage BC associated with the COVID-19 crisis. These findings support recommendations for a quick restoration of BC screening at full capacity, with adequate prioritization strategies to mitigate harm.

Published: February 2024

OBJECTIVE: This study was designed to investigate the role of 8-oxoguanine DNA glycosylase 1 (OGG1) in preventing atherosclerosis-induced vascular EC injury, thereby providing a theoretical basis for the exploration of drug targets and treatment methods for atherosclerosis. METHODS: Human umbilical vein cell line (EA.hy926) was treated with ox-LDL to construct an in vitro atherosclerotic cell model. pcDNA3.1-OGG1 was transfected into EA.hy926 cells to overexpress OGG1. qRT-PCR, CCK-8 assay, flow cytometry, oil red O staining, ELISA, comet assay and western blot were used to evaluate the OGG1 expression, viability, apoptosis level, lipid droplet content, 8-OHdG level and DNA damage of cells in each group. RESULTS: Compared with the Control group, ox-LDL stimulation of endothelial cells significantly decreased cell viability, promoted apoptosis and DNA damage, and increased intracellular levels of 8-OHdG and γH2AX, while decreasing protein levels of PPARγ, FASN, FABP4, RAD51 and POLB. However, overexpression of OGG1 can significantly inhibit ox-LDL damage to endothelial cells, promote lipid metabolism, decrease lipid droplet content, and improve DNA repair function. CONCLUSION: Over-expression of OGG1 improves DNA repair. Briefly, OGG1 over-expression enhances the DNA damage repair of ECs by regulating the expression levels of γH2AX, RAD51 and POLB, thereby enhancing cell viability and reducing apoptosis.

BACKGROUND: The triad “insulin resistance, prediabetes, diabetes” is three independent neologies with characteristic features and development. In addition, each are characterized by progression and the possibility of transition from one form to other. Due to the fact that diabetes is one of the common diseases associated with high rates of disability, it is necessary to improve diagnostic methods and educational regimens for successful prevention and treatment of the disease. OBJECTIVE: We investigated Band 3 protein (B3p) level, osmotic resistance of erythrocytes, the total antioxidant activity (TAA) of blood serum, level of HbA1 in group patients with insulin resistance (IR), prediabetes, and Type 2 Diabetes Mellitus (T2DM) and comparative with health control group. METHODS: We used original, accurate research methods that measure the essence of the studied quantities. RESULTS: Disruptions of glucose and insulin homeostasis ay lead to the initiation of oxidative stress (in our study demonstrated by a decrease of TAA of blood serum) increased redox-sensitive PTP activity and aberrant band 3 phosphorylation, potentially leading to reduced erythrocyte deformability. At the same time glycation of Hb during T2DM may affect its cross-link with membrane proteins, in particular with B3p, and although appears to limit its cross-linking and decrease its clusterization ability, induces alterations in the cytoskeletal matrix, and thereby decrease erythrocytes’ osmotic resistance making them more susceptible to hemolysis. CONCLUSIONS: The osmotic resistance of the erythrocytes can be used as a sensitive marker for the detection of the early stages of hyperglycemia (prediabetes). This set of clinical trials will make it possible to identify diseases that make up the triad at an early stage. Early detection of disorders and continued research in this direction will help in the development of a diagnostic scheme for the prevention of such patients. Based on our data, research into anti-oxidation drugs is very important. With the help of the array of studies described in the article and antioxidant treatment, the likelihood of successful treatment will increase.
