The increasing prevalence of brain tumors necessitates accurate and efficient methods for their identification and classification. While deep learning (DL) models have shown promise in this domain, their computational demands pose challenges when deploying them on resource-constrained mobile devices. This paper investigates the potential of Mobile Edge Computing (MEC) and Task Offloading to improve the performance of DL models for brain tumor classification. A comprehensive framework was developed, considering the computational capabilities of mobile devices and edge servers, as well as communication costs associated with task offloading. Various factors influencing task offloading decisions were analyzed, including model size, available resources, and network conditions. Results demonstrate that task offloading effectively reduces the time and energy required to process DL models for brain tumor classification, while maintaining accuracy. The study emphasizes the need to balance computation and communication costs when deciding on task offloading. These findings have significant implications for the development of efficient mobile edge computing systems for medical applications. Leveraging MEC and Task Offloading enables healthcare professionals to utilize DL models for brain tumor classification on resource-constrained mobile devices, ensuring accurate and timely diagnoses. These technological advancements pave the way for more accessible and efficient medical solutions in the future.

Background and Aim: Cyclophosphamide therapy is known to be associated with the risk of female infertility as a result of ovarian toxicity. Alpha-lipoic acid (LA) and omega-3 fatty acids are known for their antioxidant and anti-inflammatory activities. The present study investigated the potential protective effect of alpha-LA, omega-3 fatty acids, and its combination against cyclophosphamide-induced ovarian toxicity in rats. Materials and Methods: Thirty rats were equally divided into Groups I, II, III, IV, and V. Group I was normal control, wherein the rats were fed with normal feed and water ad libitum. Group II served as cyclophosphamide-induced group, wherein the rats were injected with cyclophosphamide at 75 mg/kg through intraperitoneal route once a week to induce ovarian toxicity. Groups III and IV were treated with alpha-LA at the rate of 25 mg/kg and omega-3 fatty acids at the rate of 400 mg/kg, respectively, in parallel to cyclophosphamide induction as in Group II. Group V animals were coadministered with alpha-LA (25 mg/kg) and omega-3 fatty acids (400 mg/kg) along with cyclophosphamide induction as in Group II. The respective treatments were administered daily through oral route for a period of 30 days. Regularity of estrous cycle was evaluated by vaginal cytology. Post-treatment period, the animals were humanely sacrificed, and the blood samples were subjected to the estimation of follicle-stimulating hormone (FSH) and estrogen. The ovarian tissue was weighed and subjected to histopathology, transmission electron microscopy, estimation of decreased glutathione (GSH), and tumor necrosis factor (TNF)-alpha. Results: Rats treated with cyclophosphamide alone manifested irregularity in estrous cycle, increased FSH, and reduced estrogen levels. The ovaries showed decreased GSH and increased TNF-alpha concentrations. Histopathological and transmission electron microscopic analysis of the ovarian follicles revealed degenerative changes. Administration of alpha-LA and omega-3 fatty acids as well as the combination of both the treatments demonstrated significant normalization of the estrous cycle and antioxidant defense mechanism as well as ameliorated the hormonal profile and histological architecture of the ovarian follicles. However, appreciable synergistic efficacy of the combination therapy (alpha-LA+omega-3 fatty acids) with respect to the monotherapies was not observed in the present study. Conclusion: The efficacy of alpha-LA and omega-3 fatty acids against cyclophosphamide-induced ovarian toxicity could be attributed to its antioxidant and anti-inflammatory activities that prevented the oxidative damage to the ovaries caused by cyclophosphamide. Hence, our findings suggest that dietary supplementation of alpha-LA and omega-3 fatty acids in women receiving cyclophosphamide therapy could carry potential benefits in preventing cyclophosphamide-induced infertility in childbearing women.

Introduction: Sodium channelopathies are a group of genetic disorders characterized by abnormalities in sodium channels that can cause a wide range of cardiac and neurological symptoms. These disorders can be inherited in an autosomal dominant pattern and can be caused by mutations in various genes, including SCN5A, SCN1B, and SCN2B. A comprehensive literature search was conducted using PubMed, MEDLINE, and Google Methodology: Scholar to identify relevant articles published from March 2005 to November 2021. The following keywords were used: "sodium channelopathies", "sodium channels", "sodium channelopathy genetics", "sodium channelopathies-pathophysiology", "sodium channelopathies- their clinical presentations and management". Only articles written in English and reporting on human studies were included. The clinical presentation of these disorders can vary widely, Clinical features and management: ranging from asymptomatic to sudden cardiac death, and can be inuenced by factors such as age, gender, and comorbidities. Genetic testing can aid in the diagnosis and management of these disorders, and there are several treatment options available, including medications, implantable cardioverter-debrillators, and lifestyle modications. Conclusion: While signicant progress has been made in our understanding of sodium channelopathies in recent years, there is still much to learn about these complex disorders. Further research is needed to fully elucidate the underlying mechanisms of these disorders, identify novel therapeutic targets, and improve clinical outcomes for affected individuals. Nonetheless, the knowledge gained so far has provided valuable insights into the pathogenesis and management of these disorders, and has the potential to greatly improve the lives of those affected by sodium channelopathies.

Increase in demand for energy production and its supply, rise in petroleum prices, environmental issues have lead in search of new alternative energy resources. This eventually lead in using edible oils as essential feed stock but in recent years, the food verses fuel controversy made edible oil a non-ideal feed stock. In search for alternative non-edible feed stocks, GuizotiaAbyssinica and CucumisSativus seed oils were found to be potential feed stocks for the synthesis of Bio-Diesel through transesterification process using Crystalline Manganese Carbonate as catalyst. Crystalline Manganese Carbonate was found to be a sustainable catalyst since higher yields were obtained at 1 wt% catalyst for both the oils. The catalyst is pure, crystalline and ash colored in nature. It is a heterogeneous catalyst and promotes reuse of the catalyst for all most seven successive runs. It is a low cost and easily available, non-corrosive, versatile, environmental friendly, green and sustainable catalyst for the transesterification of non-edible feed stocks. In the present study, a comparison on effects of parameters like methanol quantity, catalyst amount, reaction time and reaction temperature for GuizotiaAbyssinica and CucumisSativus seed and Edible oils are done. The results show that using the catalyst CrystallineManganese Carbonate gives higher yields and conversions. The catalyst is neither corrosive nor emulsion forming and is easier to separate. The research focuses on sustainable catalyst and feed stocks that are economic and environmental friendly

General Nursing ,Education - Abstract
Text summarization is the process of employing a system to shorten a document or a collection of documents into brief paragraphs or sentences using various approaches. This paper presents text categorization using BERT to improve summarization task which is a state-of-the-art deep learning language processing model that performs significantly better than all other previous language models. Multi-document summarization (MDS) has got its bottleneck due to lack of training data and varied categories of documents. Aiming in this direction, the proposed novel hybrid summarization B-HEATS (Bert based Hybrid Extractive Abstractive Text Summarization)framework is a combination of extractive summary via categorization and abstractive summary using deep learning architecture RNN-LSTM-CNN to fine-tune BERT which results in the qualitative summary for multiple documents and overcomes out of vocabulary (OOV). The output layer of BERT is replaced using RNN-LSTM-CNN architecture to fine tune which improves the summarization model. The proposed automatic text summarization is compared over the existing models in terms of performance measures like ROUGE metrics achieves high scores as R1 score 43.61, R2 score 22.64, R3 score 44.95 and RL score is 44.27 on Benchmark DUC datasets.

A new tetradentate binucleating ligand [H2L] has been synthesized by condensation between 3, 3′-diaminobenzidine and o-hydroxyacetophenone in the molar ratio 1:4. The reaction of the ligand with metal chelation leads to bimolecular complexes of the general formula [M2(L)]. The ligand and metal complexes have been characterized by elemental analysis, UV, IR,…1H NMR, 13C NMR, conductivity measurements and magnetic studies. In conductivity experiments, all metal chelates showed to be non-electrolytic in nature. The bonding sites are the nitrogen atoms of the azomethine and the oxygen atoms of the phenolic groups. The anti-microbial activities were screened against one Gram-positive bacterium (Streptococcus pyogenes) and one Gram-negative bacterium (Klebsella pneumoniae). The anti-fungal activity was screened against Asperigillus flavus. All complexes showed significant anti-bacterial and anti-fungal activities. The DNA binding studies were performed by electronic spectroscopy, cyclic voltammetry studies and viscosity measurements. The cleavage studies of these complexes are investigated by gel electrophoresis method in the presence of peroxide. All complexes cleaved efficiently and the complex interacts with DNA through an intercalating way.

Slow evaporation method at constant temperature was used to generate optically better-quality clove and pure doped Potassium Di-hydrogen Phosphate crystals, which were then characterized. If the optimum conditions are adequately attained, the slow evaporation method can be used to produce crystals with low solubility. FTIR spectra are used to assess the reality of crystal efficient groups qualitatively. To investigate the dopants effect on the ideal appearances of Potassium Di-hydrogen Phosphate, an X-ray diffraction investigation was carried out. The tetragonal design of KDP and incapacitated crystals was discovered via powdered X-ray diffraction. The lattice parameter values were determined using X-ray diffraction on a single crystal. UV-Visible spectroscopy was used to examine the generated clove doped (1:1) KDP crystals. The TG and DTA analysis were utilized to examine the constancy and breakdown of unpolluted and clove doped KDP crystals. ND-YAG laser was utilized to notice the SHG. Clove doped KDP crystals outperformed pure KDP crystals in terms of relative generation of second harmonics productivity. The effect of dopants on the exterior morphology of KDP crystals was investigated using a scanning electron microscope (SEM). EDAX was utilized to have a better understanding of the elements found in crystals.

The subversion of the body and mind of women is a complex and pervasive issue that has been present throughout history. It takes many forms, from physical violence and sexual assault to more subtle forms of discrimination and social conditioning. However, even less overt forms of violence, such as verbal harassment and intimidation, can significantly impact women's wellbeing and sense of safety. This paper is an exploration of Atwood's novel Bodily Harm to expose the inhuman and stigmatic attitudes meted out against women by subverting their bodies and minds. Further, this paper is based on the argument that power politics, gender discrimination, and trauma reflect changes in the lives of Rennie, the protagonist, and other female characters while pointing out the problems they face and the reasons for the problems.

Through-silicon-via (TSV) technology has emerged as the key technology to enable 3D IC integration. 3D integration is seen as the leading candidate, which can help in sustaining Moore’s Law to future IC technology nodes. It clearly set a benchmark to the IC industry due to its tremendous benefits in performance, data bandwidth, and supports heterogeneous integration. In 3D IC structure TSV’s are used to carry the overall electrical signal between the layers. The major drawback in the TSV based 3D integration is noise coupling between aggressive (electrical signal carrying TSV; ETSV) and victim TSV’s (ground). It can be reduced by creating very good isolation between TSV’s and Si substrate by using different liner materials around TSV’s. In this work, we have addressed various TSV models to reduce noise coupling between the TSV’s. The models we have studied are single layer model and stacked layers of liner model. Apart from this we have studied how the core materials in the TSV reduces noise coupling between aggressive and victim TSV’s. Also, we have shown the high frequency study for proposed models. Finally, our work shows single layer model with Crystalline-Germanium is comparably better noise coupling reduction even at higher frequency.

The objective of this study was to determine the liver oxidative stress status of grey mullets living in heavy-metal-rich polluted Ennore estuary compared with unpolluted Kovalam estuary. Fish were collected from both estuaries during the monsoon and summer seasons from October 2004 to September 2006. Fish liver homogenate (N = 20 per group) was prepared for evaluating oxidative stress parameters. Fish living in the polluted estuary had significantly higher lipid oxidation products, conjugated dienes (0.346 ± 0.017 vs 0.141 ± 0.012 DA233/mg protein), lipid hydroperoxides (0.752 ± 0.032 vs 0.443 ± 0.03 nmol/mg protein), and lipid peroxides (3.447 ± 0.14vs 1.456 ± 0.096 nmol MDA/mg protein) than those of the unpolluted estuary during the summer. In contrast, significantly lower levels of superoxide dismutase (20.39 ± 1.14 vs 53.63 ± 1.48 units/mg protein) and catalase (116 ± 6.87vs 153 ± 8.92 units/mg protein) were detected in the liver of fish from the polluted estuary (Ennore) compared to fish from the unpolluted estuary (Kovalam) during the summer. Variations in most of the oxidative stress parameters were observed between the summer and monsoon seasons, indicating the importance of seasonal variation for estuaries and their inhabitants.

Background: Cisplatin is one of the most remarkable solutions in ‘the war on cancer’. Although cisplatin has been a mainstay for cancer therapy, its use is mainly limited by nephrotoxicity. The current study was aimed to evaluate the ameliorative potential of Terminalia arjuna (TA) in comparison to taurine against cisplatin toxicity. Methods: A total of 36 male Wistar rats were divided into 6 groups of 6 rats in each. Group 1 was normal control. Cisplatin @ 5 mg/kg b.wt was injected on day 1 to groups 2, 5 and 6. Aqueous leaf extract of Terminalia arjuna was administered orally @ 400 mg/kg b. wt to groups 3, 5 and Groups 4, 6 recieved taurine orally @ 1000 mg/kg b.wt for 14 days. Blood samples were collected from animals to assess Kidney function tests, oxidative stress and cytokines and renal tissues were examined for histological changes, if any. Result: Antioxidant profile, serobiochemical and cytokine parameters were significantly (P less than 0.05) increased and histopathological studies revealed degenerative changes and marked infiltration in the kidney of group 2 when compared to groups 1, 3 and 4. However, These changes were reversed in groups 5 and 6 that were administered with Terminalia arjuna and taurine, respectively. In conclusion, the results of the present investigation elucidated that both Terminalia arjuna and taurine have potent nephroprotective activity in cisplatin injected Wistar rats.

Anomaly is in general defined as deviation or diversion from the normal. The word anomaly came from the Greek word anomalia which means “uneven” or “irregular”. In our day-to-day lives, we have seen many such irregularities or deviations from normalcy. For example, a condition monitoring system beeps an alarm when it detects any value or parameter of the machine away from the minimum value limit to the maximum value limit, or a credit card fraud alerts the bank and the customer immediately. Now, the crucial task here is how we detect anomalies in data streams. When there is streaming data that is continuously generated from any source, it is called a data stream. The task of finding anomalies from such a stream of data will be a challenging job. In this paper, we will discuss elaborately about data streams and anomaly detection in data streams by reviewing several papers and articles written on this topic.

Nowadays, one-day rapid growth in technology has been seen. Within the context of recent healthcare, the utilization of IoT technologies brings their convenience to physicians and patients as they are applied to varied medical areas. The development of new technology in healthcare applications without regard to safety makes patient privacy vulnerable. In this study, we highlighted key security requirements when storing patient information in the cloud. When we consider the hospitality facilities in the villages, they face a lot of problems with the fact that the doctors are not able to visit the rural clinics often; they always want to take all the medical history, medicines, and records with them; and they have to stand in front of the hospitals. Accordingly, providing an honest quality of life for people has become a big social challenge at that point. The rapid proliferation of knowledge and communication technologies has led to the approval of innovative trend solutions and tools that show commitment to meeting challenges. There has been a long struggle to maintain access to quality health services with consulting physicians in rural areas. When we consider the major challenges facing rural public hospitality, such as lack of infrastructure, poor manpower, cost, quality of health services, and time required to provide services to patients, the treatment recommendations of the IoT doctor and patient updated treatment information will be stored directly in the [1] cloud [2]. In order to be effective in storing information on the cloud, we must provide secure communication protocols. We propose a secure IoT based on the sensors used in modern healthcare.

Expansive soil deposits mostly appear in arid and semi-arid areas of the world and they pose severe difficulties to engineering constructions as they possess higher tendency to heave in the course of moist season and shrink at summer season. Construction in such highly expansive strata can be done by adopting ground modification techniques like soil stabilization, Vertical drains, inducing reinforcement in to soil etc., On the other hand with rapid industrial growth more quantity of industrial waste will be generated which will trigger several environmental issues when it is dumped in to environment. Utilization of industrial waste in construction industry without compromising in strength criteria is the best possible option for the engineers as the waste is used as construction material there will be no need for dumping yards, biodiversities can be protected, strength properties of the soil can be enhanced and hydraulic properties can also be modified by treating soil with industrial wastes. As the river sand can be partially replaced by some of the industrial wastes requirement for natural sand can be reduced which will not only economise the construction cost but also preserves the natural resources. The present study was carried out to assess the behaviour of coir pith treated black cotton soils. Due to increase in the natural fibres in many industries the waste produced from the coir industry is increasing, if proper care is not taken these waste may create severe effects on environment .To avoid disposal of this waste directly into environment it is better to use the waste in construction industry is a better option. But before adopting such practices proper studies are to be done to check whether these materials are suitable for treating the soils are not .In the present study by adding various proportions of coir pith Swell, strength characteristics of soil where compared for obtaining the optimum Replacement percentage.

We designed and developed a novel framework DWIRS for Deep Exploration with indexing and ranking. The purpose of DWIRS framework is to explore high quality contents from the quantitative Deep Web, with least possible effort, in the least possible time, irrespective of architectural dependencies and operating system related issues. It is imperative to perform indexing and ranking is the nucleus of the exploration process. The design of the proposed framework is carried out in three phases: Indexing, Standard Search and Ranking Search. In phase 1, the acquired Deep Web data is pre-processed through Tokenization, Stop Word Removal and Stemming. Then, indexing is performed for the Deep Web data. The exploration process is carried out based on the search keyword provided by the user. Cosine similarity measure is used in standard search. The search results are re-ranked by using BRF algorithm. The performance of DWIRS framework has been evaluated by developing a customized application on the collected Deep Web data sets. By comparing the results of standard search with that of ranking search, it is shown that retrieval effectiveness as well as the quality of search results has been improvised. Our experimental results revealed that the proposed framework works effectually.

The term anomaly is derived from a Greek word anomolia meaning uneven or irregular. Anomalies are often referred to as outliers in statistical terminology. For a given set of data if we plot a graph and observe, all the data points that are relative to each other will be plotted densely, whereas some data points which are irrelevant to the data set will be lied away from the rest of the points. We call those points as outliers or anomalies. Anomaly detection is also called as deviation detection, because outlying objects have attribute values that are significantly different from expected or typical attribute values. The anomaly detection is also called as exception mining because anomalies are exceptional in some sense. Anomalous data object is unusual, irregular or in some way, inconsistent with other data objects. In this case, unusual data object or irregular patterns need not be termed as not occurring frequently. If we take a large data set or a continuous data stream, then an unusual data object, that occurs ‘one in a thousand’ times, can occur millions of times in billions of events considered. To find out the anomalies in data sets, we have many approaches like statistical, proximity–based, density–based and cluster–based. Statistical approaches are model-based approaches where a model is created for the data and objects are calculated with respect to how they are relative with all other objects. In this paper, we will be discussing various statistical approaches to detect anomalies. Most statistical approaches to outlier detection are based on developing a probability distribution model and considering how probable objects are under that model.

Worldwide in the construction industry uses reinforced cement concrete. The different types of structures which were built using reinforced cement concrete served for long period. But due to faulty design, improper quality control and corrosion of reinforcement there are notable premature failure and subsequently sudden collapse of the structure occurs. The presence of aggressive medium such as moisture and chloride ions are the main factors which are induces the steel corrosion. The cost involves for repairing the corroded structure escalate very rapidly which leads property loss to the people, if the problem is not corrected. Columns are the main structural members of R.C bridges when exposed to de-icing salt they are more vulnerable to steel reinforcement corrosion. The thorough knowledge about the corrosion can get only by proper investigation. This experimental work mainly focuses on structural behaviour R.C columns subjected to steel corrosion. Columns with two different size were cast and accelerated corrosion was induced. Structural behaviour of the columns were studied with axial load test and compared with conventional specimen.

This paper deals with numerical investigation using finite element software, ABAQUS CAE, for the analysis of precast reinforced concrete (RC) column connected to the foundation containing protruding bar in grouted sleeve subjected to axial, and lateral loads, including the cyclic loading response. The monolithic connection of column and foundation is designed and the same has been used for the design of precast concrete column and foundation. The model focusses on the length of the protruding bar provided in the foundation that is connected to the column through the grouted sleeve. As there is lack of Indian standard codes in the design of precast concrete connections, an attempt has been made by varying the length of protruding bars. The model was subjected to quasi-static loading condition and parameters such as ultimate load carrying capacity, load-displacement hysteresis, ductility and plastic strain were studied and were compared with that of monolithic connection. The results proved that when the length of protruding bars provided was equal to development length of the bar provided, the results were comparable with that of monolithic connection.

Boswellia serrata is an Indian herb known for its potent anti-inflammatory and anti-arthritic properties in ancient folk medicine. The present study was undertaken to evaluate the anti-arthritic potential of Boswellia serrata on radiographic joint damage and histopathology of adjuvant-induced arthritis. Thirty male Wistar rats were randomly divided into 5 groups with six rats each. While group 1 served as normal control, arthritis was induced in animals belonging to groups 2 (arthritic control); 3, 4 and 5 (treatment groups) by injecting 0.1 ml of Freund's complete adjuvant, intradermally into the hind foot pad. Treatment protocol was followed from 3rd to 21st day, with Boswellia serrata given orally as methanolic extract @ 500 mg/kg b.wt. to group 3, meloxicam given subcutaneously @1 mg/kg b.wt. to group 4 and both the drugs given concurrently to group 5. The onset and progression of arthritis were assessed weekly by radiographic interpretation. The drug effects were evaluated on the histopathology after completion of the experiment. The extent of paw inflammation before treatment and its subsequent amelioration after treatment were noticed in groups 3, 4 and 5 Boswellia serrata showed better amelioration compared to meloxicam with a superior curative effect witnessed when both the drugs were administered together. The significant alleviation of joint damage in adjuvant-induced arthritis may be attributed to the pharmacologically active principles present in the extracts of Boswellia serrata.
