In this study, Chitosan-Xyloglucan encapsulated Titanium dioxide was prepared by in-situ method for coating Silk fabric. FT-IR XRD characterized the functional groups and formation of crystallization of composite film. SEM analysis showed the immobilization of composite film on the surface of silk fabric. The coated silk fabrics were stained with methylene blue, and the stain removal efficiency was evaluated. The results showed that the composite film was deposited onto the silk fabric. The functional groups showed peaks around 1635 to 1636 and 400 to 500 cm-1 that indicate the presence of C=N groups of Chitosan-Xyloglucan and Ti-O groups of TiO2 on the composite, respectively. The XRD results indicated that the TiO2 prepared by the sol-gel method was an anatase crystalline structure. The mechanical properties showed the composite film was superior to the Chitosan-Xyloglucan, TiO2, and uncoated silk fabric. Finally, the methylene blue degradation capability was investigated. The coated silk fabric has insignificantly removing methylene blue stain than the untreated silk fabric, but it is noticeably repellent to stain.
Empowering Young Adult Second Language Learners through Extensive Reading Practices
Authors: Samaraweera S. G. S.
Published: March 2024

Although English as a second language learners identify linguistic forms, structures, rules, and functions in the classroom, they are not able to use them correctly in receiving and producing meaning due to a lack of exposure to the language. Second-language learners can be exposed to the target language through extensive reading. Extensive reading may help the learner to recognize the function of linguistic forms, structures, patterns, and vocabulary of the target language and facilitate the learner to receive and produce meaning independently. Therefore, this study investigated the viability and validity of incorporating the extensive reading component into second language (L2) programmes designed to develop receptive and productive skills. This quasi-experimental study was conducted with 70 undergraduate students of both genders divided into two groups: experimental and control. Both groups were taught the same syllabus by the same teacher. However, the participants of the experimental group (N=35) were engaged in extensive reading programme whereas the participants of the control group (N=35) were not. When the achievement results of the two respective groups were compared, the results of the experimental group indicated a significant increase in receptive and productive skills. Therefore, extensive reading can be considered an effective and useful instrument in developing L2 receptive and productive skills.

Authors: Wijeratne S.
Published: March 2024

The Morawaka Kanda area has become heavily impacted by the landslides in the recent years resulting in socio-economic and environmental damages. This area which consists of steep slopes, soft soil layers with feldspar, poor drainage, constructions, deforestation, settlements and gardens may be at high potential risk for landslides. Therefore, in this study, special attention has been drawn to examine the risks of landslides on the Morawaka “Kanda” area in the Matara district. The research framework of this study was planned based on field surveys for the data collection of landslide risks using a data collection sheet and questionnaire. Satellite data taken by survey department was used for the risk area mapping using Geographical Information Systems (GIS). According to the analysis of causative factors, high risky land area is about 18 km2 and it is 24% of the area. The land extent of moderate and low risk is nearly 64% of the total area in this study area. The moderate landslide risk areas covered 24.14km2 land. It is about 31%. 25km2 is about low risk. 45% is low and no risk. Still there is a risk for future landslides in the unstable slope on the right bank of the Morawaka Kanda landslide path in 2017. 55% of the families live in the high risk area and only 20% of the families are in the moderate risk while 25% of the families have low or no risk. 50% of the high risk families are in Morawaka Kanda and Yati Horagala. The identification of landslide prone areas play an important role in avoiding or minimizing hazards and the identification of potential landslide risk areas is very important to ensure the safety of lives and property.
The Structure and usages of future forms in Classical Sinhalese Literature
Authors: Ariyawansa Thero Morakandegoda
Published: March 2024

This research paper is presented to identify the morphological and practical approaches to the future verb appearing in the prose language of classical Sinhalese. According to records, five formations of the future verb can be identified. This shows that the future verbs of the Sinhalese language were not clearly identifiable in classical literature. Therefore, it is possible to observe how different formations were used to convey the same linguistic meaning. There are two future formations in the traditional standard grammar of Sinhalese. According to the facts found in religious texts which were written in the Classical Sinhalese Period, some other formations of future verbs are realized. This research is mainly based on the qualitative research method. The data is collected from primary and secondary resources. The future forms used in the Classical Sinhalese Period are taken into account in this research. The religious texts such as Dharma Pradīpikā, Amāvaturǝ, Butsarǝɳǝ, Pūɟāvəlijə, Saddharmə Ratnāvəlijə, and Pansijəpaɳas Ɉātəkə Potə are considered as main primary resources in the research. These literary works which were written in the Classical Sinhalese Period have been selected for the research because they represent the written and spoken varieties, the standard and non-standard varieties of the Sinhalese language. The data collected from the texts is categorized and analyzed according to the relevant formations of the future tense. According to the facts found in the above-mentioned religious texts, there are five formations of future forms. They are as follows: the future form with future meaning, the future form with present meaning, the adverb of (future) time with the future verb form, the adverb of (future) time with the present verb form and the representation of the future meaning by the present form. Therefore, two future formations of traditional grammar are developed up to five in the Classical Sinhalese literature.

Published: March 2024

We report the case of an incidental finding of a huge aneurysm of the ascending aorta with a congenital bicuspid aortic valve type 0-lateral. This severe condition was totally unknown to the patient, who was asymptomatic for cardiovascular disease. The aneurysmal mass involved the entire mediastinum, altering the normal anatomical relations, so the operative strategy was modified intraoperatively, tailoring the surgical technique to the anatomical conditions found. Despite a delayed awakening, the patient had an uncomplicated postoperative course. Therefore, this case highlights the importance of not underestimating nonspecific, seemingly harmless symptoms and signs that may reveal potentially catastrophic pathologies, while also focusing on the surgical technique used. The modified Cabrol procedure, while an underutilized technique, if present in the cardiac surgeon's "arsenal," can represent a life-saving strategy in complex cases requiring an aortic valve and ascending aorta replacement.
Logistic regression
Authors: Pal Ankita
Published: March 2024

Logistic regression is used to obtain the odds ratio in the presence of more than one explanatory variable. This procedure is quite similar to multiple linear regression, with the only exception that the response variable is binomial. The result is the impact of each variable on the odds ratio of the observed event of interest. The main advantage of performing logistic regression is to avoid the effects of confounders by analyzing the association of all the variables together. In this article, we explain how to perform a logistic regression using practical examples. After defining the technique, the assumptions that need to be checked are explained, along with the process of checking them using the R software.

Published: March 2024

Purpose

The aim of this study was to evaluate the accuracy of tumor height measurements with variable probe positions in relation to the center of the spherical shaped globe.

Patients and methods

This is a retrospective study that included 27 eyes of 27 patients with different types of intraocular tumors recruited from the Ocular Oncology Service at Kasr Alainy Hospitals, Cairo, Egypt. All patients were evaluated by ocular ultrasound using a 20 MHz B scan transducer. Frames of each tumor measurements were evaluated and reassessed to get three heights (in the same visit) at three different positions: H-1: perpendicular with the tumor at central of the scan, H-2: perpendicular with the tumor oblique to the scan, and H-3: oblique with the tumor oblique to the scan.

Results

Different types of intraocular tumors were evaluated, with choroidal melanomas being the most common (44.4%). The median measurement in H-1 was 4.76±1.89 mm (range=1.82–8.73 mm), while the median measurement in H-2 was 4.94±1.93 mm (range=1.96–8.40 mm), and that in H-3 was 4.93±2.00 mm (range=1.99–8.73 mm). There were no statistically significant differences either between H-1 and H-2 (P=0.92) or between H-1 and H-3 measurements (P=0.97). To evaluate if the tumor height measurements were affected by the tumor size, the lesions were categorized into three groups: small-sized (tumors up to 4.0 mm), medium-sized (tumors from 4.1 to 7.0 mm), and large-sized (tumors >7.0 mm) in height. The large tumors (4/27=15%) showed differences in height measurements according to the positions of the calibers.

Conclusion

There was no statistically significant evidence on the effect of angulation on tumor height measurement using the 20 MHz B scan combined with vector A scan. However, large tumors should be more accurately calculated by the conventional perpendicular height (H-1) to avoid any error.

Default mode network aberrance in subjects of alcohol and opioid use disorders during working memory task: An exploratory EEG microstates study
Authors: Dastidar Shaon Ghosh , Leon Chaithanya , Pegwal Nishi , Balhara Yatan Pal Singh , Prakash Suriya M , Tayade Prashant , Sharma Ratna , Kaur Simran
Published: March 2024

Background:

Aberrance in switching from default mode network (DMN) to fronto-parietal network (FPN) is proposed to underlie working memory deficits in subjects with substance use disorders, which can be studied using neuro-imaging techniques during cognitive tasks. The current study used EEG to investigate pre-stimulus microstates during the performance of Sternberg’s working memory task in subjects with substance use disorders.

Methods:

128-channel EEG was acquired and processed in ten age and gender-matched subjects, each with alcohol use disorder, opioid use disorder, and controls while they performed Sternberg’s task. Behavioral parameters, pre-stimulus EEG microstate, and underlying sources were analyzed and compared between subjects with substance use disorders and controls.

Results:

Both alcohol and opioid use disorder subjects had significantly lower accuracy (P < 0.01), while reaction times were significantly higher only in subjects of alcohol use disorder compared to controls (P < 0.01) and opioid use disorder (P < 0.01), reflecting working memory deficits of varying degrees in subjects with substance use disorders. Pre-stimulus EEG microstate revealed four topographic Maps 1-4: subjects of alcohol and opioid use disorder showing significantly lower mean duration of Map 3 (visual processing) and Map 2 (saliency and DMN switching), respectively, compared to controls (P < 0.05).

Conclusion:

Reduced mean durations in Map 3 and 2 in subjects of alcohol and opioid use disorder can underlie their poorer performance in Sternberg’s task. Furthermore, cortical sources revealed higher activity in both groups of substance use disorders in the parahippocampal gyrus- a hub of DMN; superior and middle temporal gyri associated with impulsivity; and insula that maintains balance between executive reflective system and impulsive system. EEG microstates can be used to envisage neural underpinnings implicated for working memory deficits in subjects of alcohol and opioid use disorders, reflected by aberrant switching between neural networks and information processing mechanisms.

Authors: Khalil Hadeel Qasim , Al-Jiboori Mohammed AK , Salman Ahmad Majd , Alhelfy Sajid H.
Published: March 2024

Background:

Elastosonography is a promising noninvasive technique that developed in recent years for evaluating thyroid nodules. It assesses nodule stiffness or displacement depending on the applied force to differentiate malignant from benign thyroid nodules.

Objectives:

The aim of this study was to evaluate the diagnostic utility of real-time ultrasound (US) elastography in the differentiation the benign from malignant thyroid nodules.

Patients and Methods:

A prospective study was carried out on 40 patients attending the US unit/radiology in Al-Imamein Al-Kadhimein Medical City in Baghdad, Iraq, from September 2018 to August 2019. All patients were examined by B-mode US, color Doppler, and real-time elastography by Voluson-E6 US machine. Final diagnoses were obtained from histological and/or cytological evaluation.

Results:

The mean age of 40 patients was 43.7 ± 11.7 years, with a range of 25–70 years. Twenty-eight (70%) of them were female and 12 (30%) were male. Of the 40 lesions, 34 (85%) were benign and 6 (15%) were malignant lesions. Malignant thyroid nodules were significantly hypoechoic, with irregular margin, taller than wider, showed microcalcification, and exhibited a significant increase in vascularity with varying rates of sensitivity and specificity. Orientation (taller than wider) was the most US predictive pattern of malignancy with sensitivity, specificity, and accuracy of 66.7%, 100%, and 92.5%, respectively. The mean ± standard deviation of the strain ratio (SR) of all nodules was 2.7 ± 2.1 (range: 0.4–13.5) with significant result. The optimal SR cutoff value was >2.5 and showed to have a sensitivity of 100%, a specificity of 88.2%, a positive predictive value of 67%, a negative predictive value of 100%, and an accuracy rate of 90%.

Conclusion:

Elastosonography can assist in the differential diagnosis of malignant and benign thyroid nodules, as strain elastosonography improves the diagnostic performance in differentiating the benign and malignant thyroid nodules. SR is higher in malignant than benign nodules.

Assessment of effects of combination of SGLT2 inhibitors and renin–angiotensin–aldosterone system blockers on the renal functions of patients of diabetic kidney disease (SGRASS-DKD study)
Authors: Halder Susovan , Bhattacharyya Arnab , Mukherjee Shatavisa , Konar Bhaswar , Halder Antareep
Published: March 2024

Introduction:

With the advent of the novel class of drug, SGLT-2-I, there are many speculations about the combined use of this class of drug with renin–angiotensin–aldosterone system inhibitors (RAAS-I) and their effects on DKD. In spite of the fact, that there is a huge prevalence of DM in India, there is hardly any Indian study regarding their combined use. Therefore, with this in mind, the present study has been conceived and conducted in the southern part of West Bengal, India.

Materials and Methods:

A total of 279 patients of DKD were recruited from different private clinics in this region over a period of 12 weeks and followed up for about a year. All the patients were initiated on RAAS-I (ACE-I, ARB, or ARNI) and SGLT-2-I was added on second visit. Statistical analysis was done after the completion of the study and significance was tested using Student t test with P value of <0.05.

Results:

The study showed a slight male preponderance and a significant decrease in FBG, PPBG, HbA1C, and ACR and an increase in serum sodium with no significant change of serum urea, creatinine, and eGFR. A slight but clinically insignificant increase in serum potassium was also noted.

Conclusion:

Combination of RAAS-I and SGLT-2-I retard the progression of DKD by their composite effects on glycemic control, albuminuria, and blood pressure in this study population. Whether combining these two classes of drugs have any synergistic effects on DKD, will have to be determined by larger studies.
Assessment and documentation of substance abuse by crisis resolution home treatment team: A quality improvement project
Authors: Raja Usman , Misra Anurag , Kar Nilamadhab
Published: March 2024

AIM:

Substance abuse is associated with mental health crises, leading to increased attendance in A and E and hospital admissions. This quality improvement project (QIP) evaluated the assessment and documentation of substance abuse of patients admitted under the crisis resolution home treatment team (CRHT) as well as any change following a teaching session as an intervention.

METHODS:

Data from 40 consecutive patients admitted under the CRHT from the 1st of September 2023 were collected. The CRHT uses the “Core Crisis Resolution Team Fidelity Scale” as the standard of practice and this was utilized as the benchmark for the QIP. A teaching session for nursing staff was conducted as an intervention. Following the teaching session, the second cycle of data was collected from 40 consecutive patients.

RESULTS:

Substance abuse was documented by CRHT in 30% of patients (12/40). However, the proportion was 70% (28/40) when documentation by other secondary services, such as mental health liaison, community mental teams, and the sources of referral were considered. Following the educational session, CRHT documented substance abuse for 37.5% (15/40). When documentation by secondary services was checked, the percentage of patients with documented substance abuse was 67.5% (27/40).

CONCLUSION:

The QIP suggested a minor improvement in the documentation of substance use after the educational session of the nurses. Multiple sessions of sessions, a longer period before reassessment to allow change of practice, and a prompt in the evaluation document might improve the assessment and documentation of substance use by the patients in CRHT.
Evaluating Performance of Conversational Bot Using Seq2Seq Model and Attention Mechanism
Authors: Saluja Karandeep , Agarwal Shashwat , Kumar Sanjeev , Choudhury Tanupriya
Published: March 2024

The Chat-Bot utilizes Sequence-to-Sequence Model with the Attention Mechanism, in order to interpret and address user inputs effectively. The whole model consists of Data gathering, Data preprocessing, Seq2seq Model, Training and Tuning. Data preprocessing involves cleaning of any irrelevant data, before converting them into the numerical format. The Seq2Seq Model is comprised of two components: an Encoder and a Decoder. Both Encoder and Decoder along with the Attention Mechanism allow dialogue management, which empowers the Model to answer the user in the most accurate and relevant manner. The output generated by the Bot is in the Natural Language only. Once the building of the Seq2Seq Model is completed, training of the model takes place in which the model is fed with the preprocessed data, during training it tries to minimize the loss function between the predicted output and the ground truth output. Performance is computed using metrics such as perplexity, BLEU score, and ROUGE score on a held-out validation set. In order to meet non-functional requirements, our system needs to maintain a response time of under one second with an accuracy target exceeding 90%.

Authors: Sánchez-Montalvo A , Lecocq M , Bouillet E , Steelant B , Gohy S , Froidure A , Bullens D , Pilette C , Hox V
Published: March 2024

Background: Chronic rhinosinusitis (CRS) is a highly prevalent airway disease worldwide. Whereas eosinophilic CRS with nasal polyps (eCRSwNP) represents its most severe phenotype, pathogenic mechanisms remain poorly understood despite a wide spectrum of in vitro and in vivo experimental models. A mouse model of experimental ovalbumin (OVA)-induced airway allergy with coadministration of Staphylococcus aureus enterotoxin B (SEB) has been widely used to study eosinophilic eCRSwNP. This study revisits the features of this model and its suitability for studying eCRS. Methodology: We implemented the most used eCRSwNP mouse model based on OVA+SEB intranasal challenges. Readouts including inflammatory features by (immuno)histology of the sinonasal epithelium (NP formation, eosinophils, epithelial and basement membrane thickness, fibrosis, goblet cells, Charcot-Leyden crystals (CLC)-like, tight junctions) and IgE production by enzyme-linked immunosorbent assay (ELISA), were compared to features of the corresponding human disease. Results: The OVA+SEB model induced eosinophilic inflammation of upper and lower airways, with epithelial and basement membrane thickening, goblet cell hyperplasia and subepithelial fibrosis in the sinuses, along increased IgE production. Except local IgE in nasal lavage (NL), which was only increased in OVA+SEB group, all other features did not differ between OVA and OVA+SEB groups. Macro- or microscopic NP were not detected. Conclusions: With the notable exception of local IgE production, the addition of SEB did not induce additional inflammatory or structural change in the sinuses from mice exposed to and challenged with OVA. This model might represent a model for severe upper airway allergy rather than a specific model of human eCRSwNP.
Improved quantum data analysis
Authors: Bădescu Costin , O'Donnell Ryan
Published: March 2024

We provide more sample-efficient versions of some basic routines in quantum
data analysis, along with simpler proofs. Particularly, we give a quantum
"Threshold Search" algorithm that requires only $O((\log^2 m)/\epsilon^2)$
samples of a $d$-dimensional state $\rho$. That is, given observables $0 \le
A_1, A_2, ..., A_m \le 1$ such that $\mathrm{tr}(\rho A_i) \ge 1/2$ for at
least one $i$, the algorithm finds $j$ with $\mathrm{tr}(\rho A_j) \ge
1/2-\epsilon$. As a consequence, we obtain a Shadow Tomography algorithm
requiring only $\tilde{O}((\log^2 m)(\log d)/\epsilon^4)$ samples, which
simultaneously achieves the best known dependence on each parameter $m$, $d$,
$\epsilon$. This yields the same sample complexity for quantum Hypothesis
Selection among $m$ states; we also give an alternative Hypothesis Selection
method using $\tilde{O}((\log^3 m)/\epsilon^2)$ samples.

Salah satu persyaratan yang harus dimiliki oli sebagai pelumas pada pesawat terbang yaitu viskositas yang baik pada berbagai suhu pengoperasian mesin pesawat. Terdapat beberapa faktor yang dapat menurunkan nilai viskositas oli seperti overheat dan jangka waktu pemakaian oli. Bedasarkan hasil tinjauan pada record AMLB diketahui bahwa pesawat King Air ini telah dilakukan ground run mencapai waktu interval 580 jam dan terakhir ground run pada tahun 2020. Selama periode tersebut belum dilaksanakan penggantian oli pada pesawat King Air. Menurut buku pilots operating manual King Air chapter servicing halaman 11-03 tentang oil system dijelaskan harus mengganti oil setiap 600 jam pemakaian. Dari hal tersebut diketahui bahwa oli pada mesin pesawat King Air telah memasuki anjuran batas interval untuk penggantian oli dan oli pada mesin pesawat telah mengendap dalam waktu yang lama. Merujuk dari hal tersebut perlu dilakukan analisis bagaimana kualitas oli pada pesawat King Air apakah masih layak digunakan atau perlu dilakukan penggantian. Metode uji karakteristik viskositas oli pada mesin pesawat King Air di laboratorium menggunakan metode uji ASTM yaitu viskositas pada suhu 40ºC dan 100ºC (ASTM D445) yang mengacu standar MIL-PRF-23699. Dari nilai viskositas tersebut dapat diketahui toleransi viskositas oli pada masing-masing mesin pesawat King Air dan tindakan yang perlu dilakukan mengacu Service Bulletin P&W Canada. Hasil penelitian menunjukkan bahwa oli mesin pesawat King Air masih bisa digunakan dalam batas toleransi sesuai ketentuan dokumen Service Bulletin P&W Canada yang tidak membolehkan mencampur oli dengan beda viskositas. Namun, sebaiknya menguras dan mengganti oli mesin sesuai ketentuan AMM, berdasarkan approved dari P&W Canada dengan standar MIL-PRF- 23699

Healthcare-associated Infections (HAIs) continue to present a significant challenge in healthcare settings, particularly within operating rooms and patient rooms where the risk of contamination is high. Despite rigorous cleaning protocols, traditional methods often struggle to fully eradicate microorganisms, contributing to a notable percentage of HAIs, especially among surgical patients. This paper examines the potential of ultraviolet (UV) light technology, specifically within the C band range (200-280nm), as a promising adjunct to conventional cleaning practices. UV-C light has demonstrated remarkable efficacy in deactivating bacteria, viruses, and fungi by disrupting their DNA, rendering them incapable of replication. This technology offers a versatile solution for sterilizing air, water, and surfaces, including hard-to-reach areas inaccessible to manual cleaning. Incorporating UV-C robots into routine cleaning procedures holds promise in augmenting the effectiveness of environmental decontamination efforts. By addressing the limitations of traditional cleaning methods and targeting residual pathogens, the integration of UV-C technology has the potential to significantly reduce the incidence of HAIs. Furthermore, the implementation of UV-C robots in healthcare facilities could lead to improved patient outcomes, reduced healthcare costs associated with treating HAIs, and a safer environment for both patients and healthcare workers. This paper synthesizes current evidence and highlights the implications of adopting UV-C technology as a crucial step toward enhancing infection control measures in healthcare settings.
Introduction to English Literature for Arab Students

When a professor prepares an introduction that has this name, s/he has to deal with a lot of ​​literary works. S/he has a single semester and a limited number of hours to accomplish the mission. What could s/he do? This prompts him/her to set limits and work on them. As we know, specifying one work for each literary genre does not mean much, but this is the only option whenever you teach non-native students. After realizing the shortcomings of the prescribed plans and their negative effects on teaching English literature to non-native speakers, I prefer to introduce my experience, and share my opinion with my colleagues in the field. Hence, I rely on my experience as a background for what I discuss in this article. I conclude that the goal of the course should focus primarily on the culture of the source language. It should be offered to students at a level that allows them to discuss, read, and criticize, and not be offered to beginners who find it difficult to master all of these literary skills. I will present this topic from personal experience and discuss it in this article.
