A Perspective on the Supersonic Solution Blowing: Nanofibers at the Forefront of Energy Storage and Conversion, and Environmental Remediation
Authors: Silva Vinícius , Medeiros Eliton , Torresi Roberto
Published: April 2024

Nanofibers play a crucial role in energy storage and conversion, catalysis, and environmental remediation applications. These nanomaterials, characterized by their high surface-to-volume ratio and porous structure, exhibit exceptional properties that render them ideal for various energy applications such as in fuel cells, lithium-ion batteries, supercapacitors, catalysis, and hydrogen production. This discussion outlines the historical context of electrospinning (ES), acknowledging its limitations in terms of commercial viability. Introducing the supersonic solution blowing (SSB) technique as a promising alternative, its energy-efficient process holds potential for commercial feasibility. The ES has remarkable advantages in nanofiber fabrication but faces limitations due to high operating costs. Solution blow spinning (SBS) offers speed and versatility; however, fibers have a broad distribution of diameters. SSB therefore overcomes some of the limitations of both ES and SBS techniques to produce defect-free nanofibers with smaller diameters at higher throughput rates. In this concise perspective paper, we emphasize the primary contributions of nanofibers to the development and optimization of materials used in energy applications. Drawing parallels with the prevalent ES and SBS techniques in the literature, we conclude with a discussion on the potential benefits that may arise as researchers increasingly explore this emerging and more efficient technique.

Authors: Silva Aleir , Xavier Franklin , da Fonseca Maria , da Conceição Marta
Published: April 2024

Composites prepared from metal oxides and materials derived from agroforestry residues have been successfully applied to remove emerging contaminants. The lignin properties, high surface area and number of functional groups, are beneficial in the preparation of TiO2 composites. In the present work, sisal residue was used as a source of lignin, and after extraction, the lignin was applied in the preparation of an adsorbent composite with TiO2 to remove bisphenol-A. The optimal conditions for lignin extraction resulted in a lignin purity of 73%. Characterization proved that the synthesized composites have a high surface area (> 100 m2 g-1), homogeneous distribution of TiO2 particles and stable surface charge. Such characteristics resulted in a lignin/TiO2 composite with a maximum adsorption capacity of 13.7 mg L-1, capable of removing up to 97% of bisphenol-A. The adsorbent can be used in six cycles, removing over 70% by the third cycle, which indicates good stability.

Published: April 2024

One of the main causes of climate change is the increased concentration of greenhouse gases from anthropogenic sources. Therefore, the search for processes that provide mitigation of these gases is imperative and very important. Dry reforming of methane (DRM) is a process that converts CO2 and CH4 in pure syngas. Thus, this study aims to evaluate the influence of the calcination temperature (500 and 700 °C) in the titanate nanotubes (TNT) structure. The calcination at 700 °C led to a new morphology in the form of titanate nanorods (TNR). TNT and TNR nanostructures were modified with Ni and used as catalysts in the DRM reaction. The CO2 and CH4 conversions were around 60 and 48%, respectively, when using Ni-TNT500 at 700 ºC, while values around 85 and 70%, respectively, were obtained using TNR in the same reactional condition. Both catalysts presented values of H2/CO ratio near 1.

Published: April 2024

Local markets boost domestic production, encourage regional businesses, improve the local economy, and structure the local economy. They are responsible for property relations, interregional economic links, and distribution of goods and services, which is especially relevant under the current foreign sanctions. This article describes a number of socio-economic indicators that affect local markets in general and construction products in particular. The study sample included local markets for construction products in Belgorod, Voronezh, Kursk, Lipetsk, and Tambov, i.e., the major cities in the Chernozem macroregion, also known as the Black Earth Region. Using the theory and methodology of strategizing, the authors analyzed data from the Federal State Statistics Service and revealed that construction work increased per capita in 2017–2021, which indicates a dynamic development of the local markets. The local markets in Belgorod, Voronezh, Lipetsk, and Kursk specialize in construction products and services. Their main strategic priorities include a prospective expansion of the range and quality of goods in order to meet the demand and satisfy the local communities and business. These local markets strive to overcome infrastructural constraints and increase the availability and quality of market infrastructure in different sectors. They level interregional differentiation, accelerate sustainable socio-economic development, and achieve local provision security. The research results contribute to urban and regional strategizing, as well as the construction industry.
Predictors of a child's psychosomatic well-being
Authors: Semenova Kristina Sergeevna
Published: April 2024

The article discusses predictors of a child's psychosomatic well-being, such as readiness for motherhood and mother's attachment to the child. Their concepts and their influence on the child's life are revealed. Readiness for motherhood is an important aspect of every woman's life. It includes physical, psychological and emotional readiness, as well as the support of people around you. Not all women are ready for motherhood, which can lead to serious consequences for the child. Physical readiness is a woman's state of health that allows her to carry and give birth to a child. Psychological readiness is a woman's ability to adapt to a new role as a mother and be ready for changes in her life. Emotional readiness is a woman's ability to experience emotions related to motherhood. An important aspect of readiness for motherhood is also the support of people around you. The attachment of the mother to the child is a key factor for ensuring the psychosomatic well-being of the child. Mothers should strive to create a favorable atmosphere in the family and support close relationships with children. They should also learn to manage their emotions and seek help from specialists if there are problems in their relationships with children. Readiness for motherhood should begin long before pregnancy and include physical, psychological and emotional preparation, as well as the support of others.

The problem of drug addiction is a problem that affects all spheres of society: economic, political, legal, large-scale, moral. Throughout post-Soviet history, since only the silence of these phenomena was a crisis, drug addiction has been an exclusively youth problem. Works from the 1990s to the early 2000s pointed to a rejuvenation of drug addiction problems: the most progressive drug addiction was in the age group from 15 to 19 years, and in the period from 2000 to 2010, the average age of initiation of drug addiction decreased to 10-14 years [7 ]. From 2012 – 2014 There was a tendency towards a restructuring of the morbidity structure, and it was revealed that the most vulnerable group of the population are people aged 18 to 40 years [6]. The average age of first trial has also shifted towards adulthood [3]. All this indicates that student youth are the most vulnerable to drug addiction risk factors. With the onset of the pandemic and the lockdown, teenagers and young people found themselves in London. Many were forced to be alone for several days due to sudden poisoning, many suffered due to losses at work and their only source of income. At the same time, psychological risk factors associated with drug use have worsened [6]. According to the data obtained by the Russian authorities, due to the reduction in the distribution and availability of narcotic substances in the first two months of the pandemic, there was a rapid decline in the detection of drug-related crimes. However, after some time, the popularity of not only communication on social networks increased, but also the sale of drugs through them among teenagers and students. According to the Ministry of Internal Affairs of the Russian Federation, drug distribution and trafficking have increased in the context of the web, and since the summer of 2020, the volumes of the illegal drug market have recovered and increased to heights [8, 9]. Thus, the period under study is 2022–2023. The youth community approached in the context of the consequences of serious psychological trauma, a shortage of anti-drug information during the covid period and an intensification of the illegal supply of drugs. Prevention 2022 – 2023 – this is largely ―catching up.‖

Published: April 2024

Fetal hypoxia is not an independent disease, but is a complication resulting from pathological processes, primarily in the mother’s body. There are many risk factors for the development of this pathological condition, which results in adverse changes in the fetal body. That is why early diagnosis is so important, the ―gold standard‖ of which is cardiotocographic examination, ultrasound diagnostics and assessment of minimal facial movements in the early stages. The purpose of the study is to study the risk factor for the development of acute and frequent fetal hypoxia, as well as the possibility of the occurrence of diseases during pregnancy and childbirth in order to determine preventive measures. For this purpose, an analysis of the necessary literature was carried out. As a result, in order to reduce the development of fetal hypoxia, it is necessary to improve the quality of health of the population in the preconception period; women with a complicated obstetric history are at high risk for this nature

A hybrid water quality prediction model based on variational mode decomposition and bidirectional gated recursive unit
Authors: Jiao Jiange , Ma Qianqian , Huang Senjun , Liu Fanglin , Wan Zhanhong
Published: April 2024

Water quality predicted accuracy is beneficial to river ecological management and water pollution prevention. Owing to water quality data has the characteristics of nonlinearity and instability, it is difficult to predict the change of water quality. This paper proposes a hybrid water quality prediction model based on variational mode decomposition optimized by the sparrow search algorithm (SSA-VMD) and bidirectional gated recursive unit (BiGRU). First, the sparrow search algorithm selects fuzzy entropy (FE) as the fitness function to optimize the two parameters of VMD, which improves the adaptability of VMD. Second, SSA-VMD is used to decompose the original data into several components with different center frequencies. Finally, BiGRU is employed to predict each component separately, which significantly improves predicted accuracy. The proposed model is validated using data about dissolved oxygen (DO) and the potential of hydrogen (pH) from the Xiaojinshan Monitoring Station in Qiandao Lake, Hangzhou, China. The experimental results show that the proposed model has superior prediction accuracy and stability when compared with other models, such as EMD-based models and other CEEMDAN-based models. The prediction accuracy of DO can reach 97.8% and pH is 96.1%. Therefore, the proposed model can provide technical support for river water quality protection and pollution prevention.

Published: April 2024

Electroplating wastewater contains heavy metal ions and organic matter. These contaminants not only endanger the environment but also pose risks to human health. Despite the development of various treatment processes such as chemical precipitation MBR, electrocoagulation (EC) ceramic membrane (CM), coagulation ultrafiltration (UF) reverse osmosis (RO), and CM RO. These methods are only effective for low concentrations of heavy metals and struggle with high concentrations. To address the challenge of treating electroplating wastewater with high heavy metal content, this study focuses on the wastewater from Dongfang Aviation Machinery Processing Plant. It introduces an EC and integrated membrane (IM) treatment process for electroplating wastewater. The IM comprises microfiltration (MF) membrane, nanofiltration (NF) membrane, and RO membrane. Results indicated that under specific conditions, such as a pH of 8, current density of 5 A/dm2, electrode plate spacing of 2 cm, 35 min of electrolysis time, and influent pH of 10 for the IM, removal rates of Zn2+, Cu2+, Ni2+, and TCr in the wastewater exceeded 99%. The removal rates of chemical oxygen demand (COD), suspended solids (SS), total phosphorus (TP), total nitrogen (TN), and petroleum in wastewater exceed 97%. Following a continuous cleaning process, the membrane flux can consistently recover to over 94.3%.

Mi Sleep Coach Mobile App to Address Insomnia Symptoms Among Cancer Survivors: Single-Arm Feasibility Study
Authors: Arring Noel , Barton Debra L , Lafferty Carolyn , Cox Bryana , Conroy Deirdre A , An Lawrence
Published: April 2024

Background

Rates of sleep disturbance among survivors of cancer are more than 3 times higher than the general population. Causes of sleep disturbance among survivors are many and multifaceted, including anxiety and fear related to cancer diagnosis and treatments. Cognitive behavioral therapy for insomnia (CBT-I) is considered a first-line treatment for insomnia; However, a lack of access to trained professionals and limited insurance coverage for CBT-I services has limited patient access to these effective treatments. Evidence supports digital delivery of CBT-I (dCBT-I), but there is only limited evidence to support its use among survivors of cancer. Broad adoption of smartphone technology provides a new channel to deliver dCBT-I, but no prior studies have evaluated mobile dCBT-I interventions for survivors. To address the need for accessible and efficacious CBT-I for survivors of cancer, the Mi Sleep Coach program was developed to adapt CBT-I for delivery to survivors of cancer as a self-directed mobile health app.

Objective

This single-arm feasibility study assessed the adherence, attrition, usefulness, and satisfaction of the Mi Sleep Coach app for insomnia.

Methods

A 7-week, single-arm study was conducted, enrolling adult survivors of breast, prostate, or colon cancer reporting sleep disturbances.

Results

In total, 30 participants were enrolled, with 100% completing the study and providing data through week 7. Further, 9 out of 10 app features were found to be useful by 80% (n=24) to 93% (n=28) of the 30 participants. Furthermore, 27 (90%) participants were satisfied with the Mi Sleep Coach app and 28 (93%) would recommend the use of the Mi Sleep Coach app for those with insomnia. The Insomnia Severity Index showed a decrease from baseline (18.5, SD 4.6) to week 7 (10.4, SD 4.2) of 8.1 (P<.001; Cohen d=1.5). At baseline, 25 (83%) participants scored in the moderate (n=19; 15-21) or severe (n=6; 22-28) insomnia range. At week 7, a total of 4 (13%) patients scored in the moderate (n=4) or severe (n=0) range. The number of patients taking prescription sleep medications decreased from 7 (23%) at baseline to 1 (3%; P<.001) at week 7. The number of patients taking over-the-counter sleep medications decreased from 14 (47%) at baseline to 9 (30%; P=.03) at week 7.

Conclusions

The Mi Sleep Coach app demonstrated high levels of program adherence and user satisfaction and had large effects on the severity of insomnia among survivors of cancer. The Mi Sleep Coach app is a promising intervention for cancer-related insomnia, and further clinical trials are warranted. If proven to significantly decrease insomnia in survivors of cancer in future randomized controlled clinical trials, this intervention would provide more survivors of cancer with easy access to evidence-based CBT-I treatment.

Authors: Talpur Bandeh Ali , Laghari 2nd Madeeha , Talpur 3rd Kazim Raza , Talpur 4th Samar Raza
Published: April 2024

BACKGROUND

On 30th January 2020, the World Health Organisation (WHO) announced the Covid-19 outbreak to be the sixth emergency services public health (SPHEC) epidemic (Waris et al., 2020). Federal Ministry of Health in Pakistan confirmed the first case of Covid-19 on 26th February 2020, in a Pakistani student returning from Iran. Over span of 15 days, 20 confirmed cases were diagnosed with Covid-19 in the province of Sindh, where highest numbers of cases were reported (Waris et al., 2020). On 27th June 2020, the numbers have reached to 198,883 confirmed cases with 86,906 recoveries and 4,035 deaths in the country . Geographically, Pakistan occupies a place of considerable significance, bordered on the west by Iran and on the northeast by China, where the number of cases and deaths during the pandemic remained enormously high, and eventually this became a major reason for the start of pandemic in Pakistan (Javed et al., 2020). Ergo, WHO officials have expressed grave concern over Pakistan that might become the next epicentre of Covid-19 pandemic (Qazi et al., 2020).

OBJECTIVE

Objective: To asses different tonal behavior of people towards Covid-19 in online social media, Twitter.

METHODS

Methods: In our study we used Whissell Dictionary of Affective Language (WDAL) to categorize people’s emotions in terms of their activeness, passiveness, and imagination towards current outbreak. Present study looked at general population of country, which then naturally split in three types of account; namely, general users, news, and organizations.

RESULTS

Results: Organizations' response to Covid-19 on social media is more conscientious, active, and they are determined to take an appropriate action to stop this outbreak in any way possible. General users on other hand on Twitter have taken this outbreak nonserious and making fun of it. Although news accounts had posted nice messages together with unpleasant messages in our dataset, yet there is no positive attitude by general public towards taking serious steps to avoid Covid-19 spread.

CONCLUSIONS

Conclusion: Our results suggest, general public is being ignorant with regard to spread of virus despite strict measures taken by the government and positive and negative framing provided by news or journalists. Present research focused on English written tweets only. However, studying behavior people who write tweets in Urdu and the role of influential spreaders on online social media towards Covid-19 remained unsolved.
Preliminary Geochemical Appraisal on Sumatera, Java, and Kalimantan Coaly Source Rocks
Authors: Jyalita Jasmin , Hendra A Donatus , Anggara Ferian
Published: April 2024

In Western Indonesia’s petroleum system, one of the hydrocarbon source rocks was deposited in parallic-deltaic environment with high organic content, categorizing it as coaly source rock. This study focused on geochemical characteristics of 25 coal and coaly shale samples from rock outcrops and well representing the Central Sumatra, South Sumatra, South Central Java, Barito, and Kutai Basin, with additional data from previous studies. TOC analysis and Rock-eval Pyrolysis were carried out to reveal the geochemical characteristics and maturation pathway of the source rock. The TOC analysis results showed a value of 0.5-67.73 wt%, indicating poor-excellent source rock potential. Further rock-eval pirolysis exhibits kerogen type II/II-III (excluding samples from Ngimbang Fm.), with gas-dominated hydrocarbon. Hydrocarbon Index ranging from 4-308 mg/gC indicates possible low-moderate quantity of hydrocarbon that can be generated by the source rocks. Despite the overall fair-good source rock potential, Tmax of the samples indicates a very poor maturity level, with only Upper Talang Akar as the mature candidate. Thus, it can be concluded that young source rock candidates in Western Indonesia (limited to the basins studied in this research) initially possess potential in generating hydrocarbons, if it is not for the immature level of most coaly source rock formations.

Published: April 2024

The Kujang Pb-Zn skarn deposit is known to be the newest skarn deposit found in the Sunda-Banda magmatic arc. The skarn orebodies are mostly hosted by limestone which might be the part of the Jampang Formation where dacite porphyry is interpreted to be the ore causative intrusion. Orebodies are mostly found at the contact between marbleized limestone and volcanic rocks and are controlled by NW-SE-trending strike-slip faults. Previous research on the mineralogy and ore characteristics of the Kujang Prospect remains limited on the preliminary studies. Using fieldwork data, petrography, ore microscopy, and assay data from core samples, this study is aimed to characterize the mineralogy of both alteration and ore of the deposit. The alteration of the Kujang Prospect skarn can be divided into 2 phases of alteration i.e. prograde and retrograde. The prograde alteration is characterized by the occurrence of clinopyroxene, wollastonite, and vesuvianite. Garnet is present in very rare amounts. the retrograde alteration is typified by epidote, chlorite, calcite and actinolite. Metalliferous minerals are represented by sphalerite, galena, pyrrhotite, chalcopyrite and pyrite. All ore minerals are formed at the early retrograde stage. the deposit’s average grade is 2.06% Pb, 6.45% Zn and 1.81% Cu.

Published: April 2024

Introduction: The COVID-19 pandemic has had an impact on the economic and business sectors in Indonesia. The pandemic has affected household food security not only in the economic sector but also in the household sector. The number of households experiencing food insecurity has increased as they cannot meet their food needs. In Sleman Regency, a forum for women farmer's groups (KWT) sells local food. One quite active is in Moyudan and Minggir Region, but the sales are not optimal, and not all have received training. Therefore, this study aims to see changes in KWT's knowledge, improve their marketing after training, and increase their economic status. Methods: This research was conducted in Sleman Regency, DIY. The training target involved the KWT in Moyudan and Minggir Region forums. We collected primary data from KWT characteristics (24 groups) and pre-post-test scores for each training (46 and 27 participants). The activities include 1) socialization of the program and bazaar of KWT products; 2) training of KWT; 3) packaging design and accompaniment; and 4) developing module training. Results: Most of KWT produces dry foods, such as vegetable and fruit chips, and shredded. Most of KWT's businesses (75.0%) are still running, although some have stopped due to difficulty in promotion during the pandemic. The obstacles experienced by KWT were using technology, arranging home industry food permits (P-IRT), and marketing. Training 1 and 2 pre-tests and post-test results increased only a little since the participants already had good knowledge (62.5% and 85.5% mainly answered correctly). However, many participants still answered incorrectly regarding the halal certification and food licensing. Ten KWTs succeeded in designing product logos and were assisted in making new, more attractive designs. Conclusion: The accompaniment can help KWT maximize its potential to improve the community's economic status.

Introduction: Many young athletes joined football schools (SSB) to gain and improve their skills, aiming to participate further in high-level competitions. However, most SSB management lacked comprehension of sports sciences, essential to support young athletes' growth and development and improved sports performance. This program aimed to improve coaches' and parents' knowledge and attitudes towards sports sciences and its implementation in SSB. Methods: Involving representatives from 13 SSBs in Sleman, an integrated training on sports sciences comprising of long-term athlete development (LTAD), nutrition and psychological development for young athletes, coaching program, and management of SSB was carried out. Knowledge was measured before and after training using questionnaires consisting of multiple-choice questions (MCQ). A focus group discussion (FGD) was also conducted to assess participants' knowledge and attitudes about implementing sports sciences in SSB. Changes in knowledge scores were analyzed using the Wilcoxon Signed Rank Test. Results: Thirty-five participants completed both pre-test and post-test, whereas only 17 participated in the FGD. The mean score during the post-test increased significantly by 12.71 points compared to the pre-test (74.29 vs. 61.58, p<0.05) with increased passing rate (57.14% vs 25.71%). Individual's change in knowledge improved by 28.83%. As stated during FGD, participants believed in the benefits of implementing sports sciences on athletes' growth and development, health, well-being, and performance. They also believed in the possibility of implementation, considering the growing number of licensed coaches. However, the inhibiting factors might be a lack of capable human resources, funding, readiness, and knowledge. Fortunately, a few SSBs reported having partially implemented sports sciences, and all SSBs are willing to start implementing sports sciences by educating all involved parties regarding sports sciences. Conclusion: These findings concluded the program's success and the promising possibility of sports sciences implementation in SSB.

Published: April 2024

Diabetic nephropathy is a disease experienced by diabetic patients. In this disease, damage to the glomerulus occurs. The administration of antidiabetic drugs tends to cause unwanted side effects, so there is a need for alternative treatment from herbs, one of which is Cassia alata L. Cassia alata L. leaves have chemical content such as flavonoids, alkaloids, tannins, and saponins. Flavonoids reduce blood glucose levels by increasing insulin secretion and mimetic agents, tannins slow carbohydrate digestion and saponins repair pancreatic beta cells and increase glycogen in the liver. This study aims to determine the effect of Cassia alata L. ethanol on the histopathology damage score of male white rat kidney (Rattus norvegicus) induced by streptozotocin. The test animals used were 30 male white rats divided into six treatment groups, each group consisting of five male white rats, namely the normal control group, negative control group, positive control group, treatment group with doses of 500 mg/kg BW, 600 mg/kg BW, and 700 mg/kg BW.

Metabolic Syndrome (MetS) represents a combination of metabolic factors that can elevate the likelihood of developing type 2 diabetes mellitus (T2DM) and coronary heart disease (CHD). The high prevalence of MetS results in a significant socio-economic burden. However, current management approaches have limitations, prompting the exploration of functional foods and nutraceuticals as promising alternatives. The primary objective of this study is to investigate the impact of Black Glutinous Rice Fermented Beverage (BGRFB) on Short Chain Fatty Acids (SCFA) concentration in a MetS rat model. Rats were induced with a high-fat diet (HFD) and streptozotocin (STZ)-nicotinamide (NA) to induce MetS conditions. BGRFB was administered as a treatment to the MetS rat group. The results showed that the Negative Control (NC) group exhibited a significant decrease in SCFA levels compared to the normal group (N). However, administration of BGRFB to the T2 group resulted in a significant increase in SCFA levels. The SCFA levels in the T2 group were higher but not significantly different from the Positive Control (PC) group treated with metformin. Increasing SCFA production could be an effective strategy in addressing Mets. This study demonstrates the potential of BGRFB as a therapy to enhance SCFA production and improve MetS. The outcomes of this investigation are anticipated to provide insights into novel dietary approaches for MetS management.

Chrysanthemum flowers (Chrysanthemum indicum L.) have been shown to contain flavonoid compounds and exert antioxidant activity. This brings Chrysanthemum indicum potential to be developed as a nutraceutical product. This study aims to evaluate the antioxidant activity of Chrysanthemum flowers before and after the formulation of Chrysanthemum indicum flower extract as a gummy candy. Gummy candy formulas were developed using variations of gelatin and pectin as gelling agents. In this study, Chrysanthemum flower extract was formulated into gummy candy. The physical characteristics evaluated include organoleptic tests, weight uniformity, elasticity, and moisture content. Optimization was performed using the simplex lattice design (SLD) method with the aid of the Design Expert software Ver. 13. The antioxidant activity of the chrysanthemum flower extract and gummy candy extract was evaluated using the DPPH radical scavenging method. Ascorbic acid was used as a positive control. The optimum formula for preparing the gummy candy was 11.51% of gelatin and 1.24% of pectin. The evaluation of weight uniformity, elasticity, and moisture content suggested that there is no significant difference between the optimum formula and the predicted value. Both the chrysanthemum flower extract and chrysanthemum flower gummy candy had strong antioxidant activity. The IC50 value of the extract was 67.80 ± 2.37 mg/mL while the gummy candy IC50 value was 82.93 ± 2.55 mg/mL. The antioxidant activity of Chrysanthemum indicum was slightly decreased after being formulated into gummy candy. These studies suggested that scientists are expected to anticipate the decrease of Chrysanthemum antioxidant activity in the gummy manufacturing process.

Nauclea pobeguinii is a plant in the Rubiaceae family endemic to the swamp forest region of the world. Its extract is widely used in traditional medicine for the treatment of a wide variety of ailments such as malarial, Jaundice, gonorrhea, fever, and stomach discomfort. While other parts of the plant have been examined for the bioactive principles responsible for the medicinal properties, limited information is available in the literature as regards the leaves, hence this study. N. pobeguinii leaves were collected, air-dried, and pulverized. The pulverized sample was extracted with solvents (n-hexane, ethyl acetate, and ethanol) of varying polarity to obtain the crude extracts. Repeated column and thin layer chromatographic separation of the crude extracts afforded three compounds, which were characterized by their IR, 1H, 13C-NMR, and 2D-NMR spectral data. A comparison of the data with literature confirmed the compounds to be 2-hydroxylstigmastane acetate (1), Ergosta-5,6-epoxy-22-en-3-yl-acetate (2), and β-sitosterol (3). Compounds 1 and 2 are novel to N. pobeguinii.

Abstract: In the modern world, power is becoming more and more crucial for all tasks. Even with our existing array of renewable and nonrenewable power sources, we are still unable to meet our needs for electricity. The population of humans is one of these assets. For this project, jogging or walking is how we produce energy. Calorie burning occurs when you go up and down stairs. People can generate power with their weight when they walk on steps or platforms. The energy produced will be kept in a battery for subsequent use around the house. This technique can be applied in sites with a high pedestrian traffic volume, such as movie theaters, colleges, schools, and temples. Applying pressure causes the control mechanism's piezoelectric sensors to produce electrical energy. The energy produced by walking on the floor is pollution- and noise-free. You may use this technology's energy to charge other electrical devices, such as laptops and mobile phones.
PDF-Driven Q&A: A Research Paper
Authors: Sontakke Prof. Sneha R.
Published: April 2024

Abstract: Traditional methods of PDF retrieval often suffer from inefficiencies and inaccuracies due to their reliance on keyword-based search algorithms. These methods usually don't understand what words really mean and have trouble with things like different words meaning the same thing, one word meaning many things, and understanding the context. This makes the search results not very good. This project proposes a novel approach to address these shortcomings by developing a comprehensive system for efficient PDF document management and context-aware question answering. The system integrates various components, including a user-friendly interface for PDF upload, Longchain techniques for breaking down lengthy PDFs into manageable chunks, and vectorization using OpenAI's language models. These vectorized chunks are stored in the Faiss Vector Database for rapid retrieval. User queries are converted into vectors using the same language model, and a semantic search algorithm matches them against the stored PDF chunks to retrieve contextually relevant answers. By presenting these answers in a user-friendly format, the system aims to enhance accessibility and usability, enabling seamless access to pertinent information within PDF documents
