Authors: Bogdanov A. V. , Shkrabo A. I. , Shatrova A. S.
Published: April 2023

The purpose of the present research is the inventory of the sources of accumulated contaminants at the former Vostsibelement industrial site located within the municipality of the town of Svirsk of the Irkutsk region (Russia) as well as the analysis of their impact on the environmental conditions. The conducted study included the calculation of the numerical assessment criterion of the overall impact of the accumulated environmental damage site on the state of environmental safety. On the basis of the results obtained, it was concluded that the industrial site of the former Vostsiblement factory is a source of accumulated harm, as well as an extremely environmentally hazardous site posing a potential threat to the entire upper territory of the Bratsk reservoir due to its location within the boundaries of the municipality of the town of Svirsk and the water protection zone of the Angara river. Based on the monitoring data, a geostatistical dispersion model of mobile lead in soil was constructed and anomalous contamination zones were identified. Three areas with an anomalously high content of mobile forms of lead (more than 6000 mg/kg) were identified in the soil on the territory of the industrial site of the former Vostsibelement battery factory. The content of mobile lead in the surface layer (0–20 cm) throughout the industrial site is not less than 100 mg/kg, which is 17 times higher than the maximum allowable concentration. The established excess of lead content in silverweed cinquefoil (Potentilla anserina) amounted to 10 background readings. A single point sample of bottom sediments of the Angara river at the entry of the industrial site, four meters from the water edge demonstrates an excess of the background content for lead, copper, zinc by 59, 12 and 4.7 times, respectively. The conducted research, analysis of the data obtained and review of the best available technologies allowed to introduce a concept for an environmentally friendly recuperative technology for the reclamation of the former Vostsibelement factory industrial site, which is very effective both from the technical and economic, and from the legal and social-ecological point of view. It also can be considered as an option to eliminate the accumulated harm of an extremely hazardous site.

Phytoremediation of domestic sewage using a floating wetland and assessing the pollutant removal effectiveness of four terrestrial plant species
Authors: D. Arivukkarasu , R. Sathyanathan
Published: April 2023

Several developing countries have limited infrastructure and finance to treat domestic and industrial wastewater. Discharging untreated sewage pollutes the surface and groundwater. Floating wetlands are an alternate method for treating polluted surface water bodies. This study's objective is to investigate the remediation of domestic wastewater using natural buoyant bamboo as a floating raft and terrestrial plants such as Ocimum tenuiflorum, Hibiscus, Chrysopogon zizanioides, and Canna in the floating wetland treatment (FWT) system. Floating rafts with a healthy terrestrial plant were planted and made to float in four plastic tanks with domestic wastewater. The water quality analysis was carried out periodically after 0, 3, 5, 10, 15, 20, and 25 days intervals. The experimental results of FWT using C. indica showed the highest removal efficiency of the pollutants such as TSS (96%), TP (98%), ammonia (95%), and DO (45%). In contrast, Ch. zizanioides showed its maximum removal efficiencies for turbidity (90%), TDS (48%), TN (85%), sodium (53%), potassium (74%), TP (92%), EC (27%), COD (93%), BOD (95%), and E. coli (47%). This study finding showed that the best terrestrial plants for removing various nutrients and other contaminants from municipal sewage were C. indica and Ch. zizanioides. However, further research is required to utilize these terrestrial plants with substrates under long-term study.

Published: April 2023

Long-term and sustainable agricultural practices can be achieved through monitoring and evaluation of groundwater quality for irrigation operations. However, less attention was given to irrigation water quality in the Tana sub-basin, Ethiopia. The present study is aimed to assess the seasonal and spatial groundwater suitability for irrigation uses. The groundwater quality parameters measured in 40 samples in each dry and wet season were the pH, electrical conductivity (EC), Na+, Ca2+, Mg2+, K+, Fe2+, HCO3-, CO32-, Cl−, and NO3-. The groundwater suitability for irrigation was assessed using the irrigation water quality index (IWQI) and support vector machine (SVM). The results showed high and medium irrigation suitability classes in the dry and wet seasons. The proportion of groundwater samples in the medium irrigation suitability class in the dry and wet seasons, respectively, was 72.5 and 67.5%. The groundwater in the wet season is comparatively more suitable than that in the dry season, which is attributed to the leaching of accumulated salts during the wet season. To avoid a salinity threat, vigilance should be exercised when using groundwater during the dry seasons. The groundwater quality map developed here for irrigation may aid in locating better-quality groundwater sources for irrigation.
Effects of highly corrosive pipe wall and disinfectant constituent on the chlorine decay behavior in drinking water
Authors: Ma Kai , Yu Chuan , Xie Wenxi , Fan Dongmei
Published: April 2023

In this study, a pilot-scale pipeline reactor and refined total chloramine decay model were employed to study the effects of the highly corrosive pipe wall and three kinds of disinfectant constituents on the chlorine decay behavior. The bulk decay coefficient, kbulk for NaClO, NaClO + NH3·H2O, and NaClO + (NH4)2SO4 were 0.011, 0.004, and 0.004 h−1, respectively. By resorting to the refined total chloramine decay model, the comprehensive wall decay coefficient kwall appeared in the ascending order of NaClO, NaClO + NH3·H2O, and NaClO + (NH4)2SO4. The remarkable contribution of the aged cast iron pipe wall to overall total chlorine residual decay was manifested by the ratio, kwall/kbulk. The pipe wall-induced decay was related to microbe consumption and electrochemical corrosion as indicated by variations in total organic carbon (TOC), NO2−-N, NO3−-N, and Fe residual. The larger kwall for NaClO + NH3·H2O (0.720 h−1) relative to NaClO (0.465 h−1) was mainly attributed to enhanced nitrifier-mediated microbe consumption. The largest kwall for NaClO + (NH4)2SO4 (0.864 h−1) was due to the further promoted microorganism regrowth and metabolization as evidenced by the SO42- declining behaviors. On this basis, it was suggested to minimize extra inorganic salt introduction into treated water to constrain microbial development in drinking water distribution system (DWDS). Temporal-free chlorine disinfection was also recommended for the chloraminated DWDS before the critical temperature.

Authors: Jiang Chunfeng , Liu Yanqing , Zhang Chong , Li Xianning
Published: April 2023

Excessive discharge of phosphorus can produce eutrophication in aquatic environments, damaging public health, the living environment, and the economy. The conventional mechanical–biological phosphorus removal methods are not suitable for small rural domestic sewage due to the features of small scale, scattered distribution, intermittent emission, and large fluctuation. This work evaluated electrocoagulation (EC) with industrial steel as electrodes on small rural domestic sewage. Results showed that the best performance was achieved at a current density of 1 mA/cm2, electrode distance of 2 cm, electrode number of 2, pH of 7, and Hydraulic Retention Time of 30 min, respectively. Under optimum conditions, the EC process removed 93.91% phosphorus while consuming around 0.25 kWh/m3 of electricity. In addition, the electrode passivation of EC was further investigated; the long-term research found that the phosphorus removal efficiency only decreased by 4.34% after 10 days of continuous flow operation, and the operational energy consumption was 0.07 kWh/m3 at a Cl– concentration of 500 mg/L.

The results of experimental and theoretical studies of the low-frequency region of infrared spectra and Raman scattering spectra in liquid cyclic hydrocarbons (arenes) and their halogen-substituted ones are analyzed. The results of experimental studies of 13 liquids in the range 20–700 cm–1 using a high-resolution all-wavelength vacuum Fourier spectrometer (Bruker IFS 125 HR) are presented. It is shown that the appearance of spectral bands in the low-frequency region (the region of the “boson” peak) of the infrared spectra of liquids is due to the formation and decay of cluster formations in the structure of the liquid.
Trends in Cause-Specific Injury Mortality in China in 2005-2019: Longitudinal Observational Study (Preprint)
Authors: Ji Zixiang , Wu Hengjing , Zhu Rongyu , Wang Lu , Wang Yuzhu , Zhang Lijuan
Published: April 2023

BACKGROUND

Over the last few decades, although the age-standardized mortality rate (ASMR) of injury has shown a significant declining trend in China, this pattern has dramatically reversed recently.

OBJECTIVE

We aimed to elucidate the geographical, demographic, and temporal trends of cause-specific injuries, the reversal phenomenon of these trends, and the fluctuations of injury burden from 2005 to 2019 in China.

METHODS

A longitudinal observational study was performed using the raw data of injury deaths in the National Cause-of-Death surveillance data provided by the disease surveillance points system in 2005-2019. The cause-specific injuries were divided into disparate subgroups by sex, age, urban/rural region, and eastern/central/western areas of China. The burden of injury was assessed using potential years of life lost (PYLL), average years of life lost (AYLL), and PYLL rate (PYLLR). Temporal trends of mortality rates and burden were evaluated using best-fitting joinpoint models.

RESULTS

Injury deaths accounted for 7.51% (1,156,504/15,403,835) of all-cause deaths in China in 2005-2019. The crude mortality rate of all-cause injury was 47.74 per 100,000 persons. The top 3 injury types (traffic accident, falls, and suicide) accounted for 70.57% (816,145/1,156,504) of all injury-related deaths. The ASMR of all-cause injury decreased (P=.003), while the crude mortality rate remained unchanged (P=.52) during 2005-2019. A significant reverse trend in ASMR of all-cause injury was observed in urban older adults since 2013, mainly due to the inverted trend in injuries from falls. A reverse trend in ASMR of suicide was observed among individuals aged 10-24 years, with notable increases by 35.18% (annual percentage change 15.4%, 95% CI 4.1%-28.0%) in men since 2017. The AYLL and PYLLR of all-cause injury among older adults showed consistent ascending trends from 2005 to 2019 (average annual percentage change [AAPC] 6.1%, 95% CI 5.4%-6.9%, 129.04% increase for AYLL; AAPC 5.4%, 95% CI 2.4%-8.4%, 105.52% increase for PYLLR). The AYLL due to suicide for individuals aged 10-24 years showed a considerable upswing tendency (AAPC 0.5%, 95% CI 0.4%-0.7%, 8.02% increase).

CONCLUSIONS

Although the ASMR of all-cause injury decreased in China from 2005 to 2019, the trend in suicide among adolescents and young adults and falls among older adults has been on the rise in recent years. Interventions should be encouraged to mitigate the cause-specific burdens of injury death.
Participants’ Engagement With and Results From a Web-Based Integrative Population Mental Wellness Program (CHAMindWell) During the COVID-19 Pandemic: Program Evaluation Study (Preprint)
Authors: Rosansky Joseph A , Okst Kayley , Tepper Miriam C , Baumgart Schreck Ana , Fulwiler Carl , Wang Philip S , Schuman-Olivier Zev
Published: April 2023

BACKGROUND

The COVID-19 pandemic involved a prolonged period of collective trauma and stress during which substantial increases in mental health concerns, like depression and anxiety, were observed across the population. In this context, CHAMindWell was developed as a web-based intervention to improve resilience and reduce symptom severity among a public health care system’s patient population.

OBJECTIVE

This program evaluation was conducted to explore participants’ engagement with and outcomes from CHAMindWell by retrospectively examining demographic information and mental health symptom severity scores throughout program participation.

METHODS

We examined participants’ symptom severity scores from repeated, web-based symptom screenings through Computerized Adaptive Testing for Mental Health (CAT-MH) surveys, and categorized participants into symptom severity-based tiers (tier 1=asymptomatic to mild; tier 2=moderate; and tier 3=severe). Participants were provided tier-based mindfulness resources, treatment recommendations, and referrals. Logistic regressions were conducted to evaluate associations between demographic variables and survey completion. The McNemar exact test and paired sample t tests were performed to evaluate changes in the numbers of participants in tier 1 versus tier 2 or 3 and changes in depression, anxiety, and posttraumatic stress disorder severity scores between baseline and follow-up.

RESULTS

The program enrolled 903 participants (664/903, 73.5% female; 556/903, 61.6% White; 113/903, 12.5% Black; 84/903, 9.3% Asian; 7/903, 0.8% Native; 36/903, 4% other; and 227/903, 25.1% Hispanic) between December 16, 2020, and March 17, 2022. Of those, 623 (69%) completed a baseline CAT-MH survey, and 196 completed at least one follow-up survey 3 to 6 months after baseline. White racial identity was associated with completing baseline CAT-MH (odds ratio [OR] 1.80, 95% CI 1.14-2.84; P=.01). Participants’ odds of having symptom severity below the clinical threshold (ie, tier 1) were significantly greater at follow-up (OR 2.60, 95% CI 1.40-5.08; P=.001), and significant reductions were observed across symptom domains over time.

CONCLUSIONS

CHAMindWell is associated with reduced severity of mental health symptoms. Future work should aim to address program engagement inequities and attrition and compare the impacts of CHAMindWell to a control condition to better characterize its effects.

Blackout in Ukraine and challenges regarding the storage of immunobiological drugs
Authors: Golovach I.Yu.
Published: April 2023

An undeclared war has been going on in Ukraine for more than one year. Defeated at the front, Russia resorted to massive shelling of energy facilities with the aim of leaving Ukrainians without electricity and heat during the winter. As reported, since October 10, the Russians have fired more than a thousand missiles and drones at Ukrainian energy facilities. The shelling on November 23, 2022 led to a system crash — a blackout occurred. For the first time in the history of Ukraine, all of the country’s nuclear power units were shut down. In conditions of lack of light and non-working refrigerating chambers, the storage conditions of thermolabile immunobiological drugs became a new test for the medical community and patients. As you know, immunobiological drugs, which are widely used in the treatment of various rheumatological diseases, require strict storage conditions in the temperature range from +2 to +8°С. Under blackout conditions, it is difficult for Ukrainian patients to maintain optimal storage conditions for these drugs. The analysis of the studies showed that the majority of patients do not comply with the requirements for the storage of thermolabile drugs, even with the constant presence of light and electricity. Experts indicate that more and more thermolabile drugs are becoming available, and in most cases, these medications are dispensed to ambulatory patients. More thermolabile drugs are becoming available, and in most cases, these medications are dispensed to ambulatory patients. However, there is no regulation once medications are dispensed to patients and little is known with regard to what happens during transport and home storage. Previous studies suggest that these drugs are improperly stored. Future studies should focus on clinical consequences and possible solutions. It is recommended for Ukrainians to follow the rules and conditions of storage of heat-labile medicinal products during blackouts/emergency and stabilization blackouts.

Background. The problem of vitamin D (VD) deficiency in the population, in general, and in pregnant women, in particular, and related diseases, including the musculoskeletal system, remains one of the most widespread medical and social problems of our time. The purpose was to determine the frequency of musculoskeletal diseases in pregnant females at high infection risk (HIR) with impaired vitamin D status and single-nucleotide Bsml polymorphism of its receptor gene. Materials and methods. Fifty-six pregnant women (main group) with HIR and 40 healthy pregnant women (control group) had been examined. The level of 25-hydroxyvitamin D (25(OH)D) in blood was determined by the enzyme-linked immunosorbent assay, and real-time polymerase chain reaction was used to detect the mutant version of Bsml (rs1544410) polymorphism of the gene that is encoding vitamin D receptors (VDR). Statistical processing of the results was done using the resource www.socscistatistics.com. Results. HIR was due to the presence of chronic kidney diseases, carriers of pathogens of the TORCH group of infections and conditionally pathogenic microflora in the urogenital tract. The level of 25(OH)D was lower than the generally accepted optimal level in 76.8 and 15 % of pregnant women, in the main and control groups, respectively (F = 0.03; p = 0.0001). Carriers of the heterozygous genotype A/G were 67.7 % of pregnant women with HIR compared to 35 % of the control group (odd ratio (OR) = 3.95; 95% confidence interval (CI): 2.19–7.1; χ2 = 20.88, p = 0.00001), and the G/G genotype was inherent in 19.6 and 47.5 % of women, respectively (OR = 0.27; 95% CI 0.15–0.51; p = 0.00006). A third of pregnant women from the main group had a history of musculoskeletal diseases (32.14 %) versus 12.5 % in control group (OR = 3.15; 95% CI: 1.54–6.46); 71.4 % of pregnant women with HIR were carriers of A/G genotype (OR = 9.79; 95% CI: 5.10–18.82). Conclusions. The share of vitamin D deficiency/insufficiency in pregnant women with HIR is almost 77 %. The general somatic history of these women is characterized by a high frequency of the kidney diseases (37.5 %) and musculoskeletal diseases (32.1 %). Two-thirds of pregnant women with HIR, as well as with musculoskeletal diseases, are carriers of the heterozygous Bsml of polymorphic genotype A/G of the VDR gene, which probably causes a higher risk of the development of pathology in conditions of calcitriol deficiency. Studying VD status, the genetic personification of disease risks, and correction of modified factors in time, in particular, VD deficiency is seen as a promising direction for improving perinatal outcomes and the quality of life of pregnant women in general, but further research is required.

Profitability of corn ethanol production in different plant scenarios
Authors: Lourinho Ferreira Priscila , Pimenta Lucas Smith
Published: April 2023

Productive efficiency and production costs are factors that impact the economic success of sugar and ethanol plants. Ethanol is a highly demanded product and, during the off-season period of sugarcane, its residual production is insufficient to supply the market. This generates the need for imports and adversely affects the Brazilian trade balance. In this context, the ethanol produced from corn figures as a potential alternative to ensure the market supply, generating revenue and diluting plants’ operational costs by expanding its operational period throughout the year. However, access to raw materials and implementation costs can affect the economic viability of this activity. In this study, the objective was to evaluate if the profitability of corn ethanol is feasible within the context of a sugarcane-only plant to be adapted to flex, located in the state of São Paulo. The increment in the marketing margin of this fuel and its co-products was used as an indicator, taking into account the difference between the costs of raw materials in two regions. The results demonstrate that the marketing margin of corn ethanol is negative in the state of São Paulo due to its distance from major corn supplies in Brazil. Although, when we considered the potential revenue from co-products, the loss scenario is converted into profitability. Thus, it is concluded that the profitability of the corn ethanol production in this scenario depends on the commercialization of its co-products in consumer markets, such as pig farming and biodiesel plants.

Authors: Felitti Karina , Palumbo Mariana
Published: April 2023

En este artículo presentamos diagnósticos, análisis y propuestas en torno a las relaciones sexo afectivas, principalmente cisheterosexuales, en una selección de productos culturales de amplia circulación y éxito comercial en la Argentina, que dialogan con y disputan sentidos a discursos y consignas feministas. En cinco libros no académicos publicados por el Grupo Editorial Planeta entre 2018 y 2021, y un podcast producido entre 2020 y 2022, disponible en Spotify, identificamos cuatro núcleos de discusión: la novedad de una revolución de mujeres deseantes, la responsabilidad afectiva como requisito para amores democráticos y menos dolorosos, la importancia del placer sexual para el empoderamiento de las mujeres y las alternativas al sistema monógamo. Ubicamos estos productos en un contexto de popularización feminista, difusión de una cultura terapéutica que promociona el trabajo sobre sí y guiones de subjetivación vinculados al mercado y la sexualidad que configuran nuevos modelos de educación sentimental.
Los cambios climáticos durante el tiempo del Homo sapiens
Authors: Munguía-Flores Fabiola
Published: April 2023

Desde su origen, el clima ha tenido varios efectos en el ser humano. Asimismo, existen evidencias de que ha influido en los grandes pasos de nuestra especie en este planeta. Por ejemplo, en la evolución de los homínidos, en la modificación del tamaño del cerebro y el cuerpo, y hasta en la invención de la agricultura, pues requirió de una estabilidad climática. Hasta la fundación y la caída de imperios también han sido regidos por cambios en el clima. En la actualidad, por primera vez en la historia de la humanidad, somos la causa de un nuevo cambio climático y esto puede tener consecuencias importantes en nuestro estilo de vida. Dado que tendremos que adaptarnos y aprender de nuestra historia con el clima, en este artículo te cuento algunos de los eventos clave relacionados con él en la historia de nuestra humanidad.

Authors: Osornio Muñoz Nadia Maricela
Published: April 2023

La serie fotográfica Más allá del canto apocalíptico busca explorar nuevas formas de abordar la degradación histórica del Zócalo capitalino a través de un ejercicio imaginativo y subversivo. El concepto central es el regreso a la historia acuática de la Ciudad de México para repensar nuestra relación con el agua, en el contexto del cambio climático actual. La serie integra también otros elementos, como la presencia de espacios verdes en la superficie —en forma de chinampas— y en la parte subterránea, junto con el metro, las ruinas prehispánicas y especies animales. A través de esta propuesta, se busca ir más allá de las narrativas apocalípticas y proponer escenarios posibles si la industria y los gobiernos adoptan medidas que permitan una reversión gradual del deterioro ambiental.

Published: April 2023

Uno de los animales de granja que más se ven afectados por el calentamiento global son los cerdos. En este trabajo, se explorará por qué los cerdos son más susceptibles al calor que otros animales, cómo identificar a un cerdo con estrés por calor y cómo pueden los cerdos mantener su temperatura corporal normal. También se expondrán las principales estrategias que los científicos han utilizado para ayudar a los cerdos a sobrellevar el estrés por calor, principalmente mediante la modificación de la temperatura ambiente en la que se alojan. Sin embargo, todavía se necesitan más estudios para llegar a una solución práctica y accesible para todos los criadores de cerdos, ya que la implementación de algunos de estos métodos puede ser costosa. Por lo tanto, se necesita la colaboración de más científicos y personas interesadas en ayudar a los cerdos que sufren de calor en todo el mundo.

Authors: Urrejola-Contreras Gabriela Paz , Pérez-Lizama Miguel Angel
Published: April 2023

Introducción: Las evaluaciones de opción múltiple constituyen el instrumento ampliamente usado en ciencias para evaluar al estudiantado; sin embargo, la reciente pandemia exigió adaptar este tipo de instrumento al entorno virtual. Este contexto requirió valorar la calidad de los instrumentos mediante índices de discriminación, consistencia interna y relacionarlo con el rendimiento académico.

Objetivo: Evaluar los instrumentos de evaluación empleados en modalidad online durante la pandemia por COVID-19, y el rendimiento de los estudiantes en ciencias de la salud.

Método: Se realizó la revisión de los 5 instrumentos de la asignatura Estructura y Función formados por 290 bancos de preguntas aleatorias para evaluar cada contenido en estudiantes de primer año durante el 2020 en la escuela de ciencias de la salud en la Universidad Viña del Mar. Se analizaron los datos obtenidos a partir de la plataforma virtual y se interpretaron los índices de discriminación, facilidad, eficiencia discriminativa, consistencia interna y rendimiento académico mediante un informe que fue compartido con los docentes para identificar los parámetros de calidad y validez.

Resultados: Del total de bancos de preguntas evaluados, un 70.2% de las preguntas presentaron adecuada discriminación y solo un 5.6% debieran ser eliminadas. El certamen dos obtuvo el menor rendimiento promedio 3.9 ± 0.99; sin embargo, presentó la consistencia interna más alta: 81%. Al comparar todos los instrumentos se observó una mejora gradual en la formulación, reflejada en el examen final, en el que además el rendimiento académico concuerda con el promedio del semestre 4.2 ± 0.92.

Conclusiones: El rendimiento académico debe ponderarse en relación con la calidad del instrumento formulado en el que, a menor índice de facilidad, existe una mayor consistencia interna, representado por la mayor eficiencia discriminativa de las preguntas. El proceso de diseño y formulación de los instrumentos debe cuidar y examinar estas pautas para resguardar criterios de calidad.

El placer estético: William Turner
Authors: Fortoul Teresa I.
Published: April 2023

Hasta sus últimos días, William Turner vivió una vida solitaria. Aunque no fue un artista de las relaciones sociales, el pintor británico, le dió un nuevo sentido a la historia del arte. Extraordinariamente popular por su audacia y talento fue un experimentador que llevó al óleo técnicas propias de la acuarela, y se acercó al impresionismo e incluso al arte abstracto. Reconcilió al hombre con la naturaleza pues en sus pinturas, por primera vez, los paisajes tenían un papel protagónico.
Hymenolepis ackerti n. sp. (Eucestoda: Hymenolepididae) infecting cricetid rodents from the central Great Plains of North America

Hymenolepis ackerti n. sp., parasite of rodents from the tallgrass prairie ecoregion of North America is herein characterized. This tapeworm occurs in 3 species of rodents including the hispid cotton rat Sigmodon hispidus, the eastern woodrat Neotoma floridana, and the prairie vole Microtus ochrogaster. A comparison against the other 10 congeneric species known from North America reveals that this species is different based on the size of the scolex, length of rostellar capsule, testicular arrangement, and the size of cirrus sac, seminal receptacle and eggs. A comparison of mitochondrial DNA reveals that tapeworms present in sympatric mammals share the same mitochondrial haplotype and feature similar morphology, supporting their recognition as a single species. The phylogenetic position of H. ackerti relative to other species is still to be resolved, since there are no homologous sequences available for most species in the genus. Given the pervasiveness of these parasites across rodents in the continent, we recommend diligence among scientists to build public archives of tapeworm specimens collected from mammals across North America, and globally. In the present manuscript, we propose a method to sample DNA while still allowing specimens to be postfixed for staining or fluid-preserved for long term storage.

Abstract: This comparative study examined the accessibility of online learning for students with disabilities amidst the pandemic in five purposively selected countries: the Philippines, the United States of America (USA), South Africa, Italy, and Australia. A qualitative research design was used to determine and compare the accessibility of online learning in the selected countries in terms of policy, curriculum, teacher-student ratio, accommodations and supports, challenges, and improvements. Results revealed that online learning accessibility varies significantly from country to country in offering national curricula and strategies to provide accessibility and carry out inclusive education amidst the pandemic. It was found that the USA had shown a solid commitment to policy, curriculum, teacher-student ratio, accommodations, and support among the five selected countries. On the contrary, the Philippines show immense challenges in accessing online learning for students with disabilities. It is concluded that limited learning resources, lack of internet connectivity, inadequate digital literacy for teachers and students, and lack of concentration and coordination persisted as significant challenges in achieving quality online learning accessibility in a country. It is recommended that countries facing the same challenges may observe countries having quality and accessible online learning, such as the USA.

Abstract: License plate detection is an image processing technology that uses a license (number) plate for vehicle identification. The objective is to design and implement an efficient vehicle identification system that identifies the vehicle using the vehicle’s license plate. The system can be implemented at the entrance of parking lots, toll booths, or any private premises like colleges, etc. to keep records of ongoing and outgoing vehicles. It can be used to allow access to only permitted vehicles inside the premises. The developed system first captures the image of the vehicle’s front, then detects the license plate, and then reads the license plate. The vehicle license plate is extracted using image processing of the image. Optical character recognition (OCR) is used for character recognition. The system is implemented using OpenCV and its performance is tested on various images. It is observed that the developed system successfully detects and recognizes the vehicle license plate. To recognize License number plates using the Python programming language. We will utilize OpenCV for this project to identify the license number plates and the python py-tesseract for the characters and digits extraction from the plate. We will build a Python program that automatically recognizes the License Number Plate

Abstract: The notepad is made on the basic concept of a real-time voice to text conversion technology that translates said words into text exactly as the user pronounces them. We developed a real-time speech recognition system and tested it in normal surroundings. The system is made up of two parts: the first is for processing an acoustic signal acquired by a microphone, and the second is for interpreting the processed signal and translating it to words. We want a voice recognition system that is reliable and inexpensive and with a good efficiency in performance. This system allows us to take notes faster which helps us to increase productivity and maintain good work life balance at the same time. This helps people of all age groups such as kids to take down notes who find writing difficult, adults to note down paragraphs or important points more easily and elderly persons to make use of technology who find typing hard. The software program was created using an object-oriented analysis and design methodology, and it accomplishes Speech Recognition by detecting and also capturing the audio using the microphone on the device. Along with additional advantages, the suggested system decreased the note making duration to more than 50% depending on the user's speed. To address the present issues with note taking, we decided to take on and do the project.

Published: April 2023

Abstract: The current study aims to synthesize, characterize, and evaluate a specific class of heterocyclic compounds called fused polycyclic indoles, in combination with carbazoles, carbolines, and their partially saturated counterparts. These compounds have been known to have potent biological activity. The study's procedures involve synthesizing these compounds and evaluating them for central nervous system activity. Results showed that all the compounds had CNS-depressing effects in mice. Some compounds, such as YA1 and YA5, were found to have a stronger CNS-depressing activity than others. All compounds tested, YA1 to YA7, caused more than 50% change in locomotor activity when compared to a standard drug. YA3 and YA5 were found to have the highest activity at 86.2% and 83.9% respectively after 120 minutes of administration at a dose of 100 mg/kg. In addition, the acute oral toxicity studies showed that YA3 was non-toxic and YA5 was found to be toxic. The findings of the study provide evidence that these title compounds have good CNS activity.

Abstract: Plastic is one of the most common used materials in the world today, but, they cause serious environmental pollution and exhaustion of landfill space. The recycling of waste plastic recovers the material, which can be used to make new plastic products such as containers, plastic lumbers and particle boards. For this to happen, the waste plastic will first be the effect of plastic waste is environment problems such as: chain food disturb, contaminate ground water, air pollution, extinction anima, poisonous soil, and act. One of the handling for plastic waste is recycling. It starts with separating plastic waste by kind of plastic. The next step is crush it until it becomes small flakes. The Small flakes can be directly used for making product such as pot, filler material for mixing with road asphalt or plastic granulate for making a product by injection mold or extraction. In order to handle plastic waste into small flakes, plastic shredder can be used to realize the making of prototype of plastic shredder machine. The concept design of the shredder machine that is currently available is fairly similar. The shaft and blades are the critical components in the shredder machine that determines its performance. The geometry and orientation of the blades that were fitted into the single or double-shafts were found to directly affect the shredding performance. Therefore, this article aims to review the various geometry and orientations of the blades that give direct effect on the shredding performance, as well as identifying the research gaps related to the shredder machine for plastic waste materials.
