PROCESS VALIDATION OF COATED LARIAGO TABLET
Authors: Burhanpurkar, Vaibhav
Published: July 2023

Chloroquine was used as a prophylactic agent against malaria, and more recently as a mild immunosuppressive. However, due to lengthy treatment periods, adverse effects have become apparent, which included retinopathy. The structurally related hydroxychloroquine is less toxic, thought to be owing to a lower tissue accumulation in melanin rich areas. This study primarily focused on quantifying melanin binding between chloroquine and hydroxychloroquine at physiological pH to investigate the potential link between binding and reported toxicity. In addition, for the first time this study quantified the actual extent of adsorption of chloroquine and hydroxychloroquine to melanin and examined the desorption profile of both drugs from melanin to demonstrate the affinity between the pigment and the solutes. The results suggest that there is a difference between the adsorption affinities of chloroquine and hydroxychloroquine, potentially explaining the differences in bioaccumulation in retinal tissue. In addition, both solutes displayed a strong physical attraction to the absorbent.

This project features a user-friendly method for person remover from images where the user has control of which object to remove. Our system removes only one object i.e person. However, it is capable of removing multiple persons through repeated application. Our model learns to detect the person in an image using the yolo algorithm. Then, the second stage removes the person in the image and fills the space with neighbouring pixels using the pix2pix concept. We show that by using this integration, the proposed network can learn a well-incorporated structure and also overcome the problem of visual discrepancies in the affected region of the image.

Every year tens of millions of people suffer from depression and few of them get proper treatment on time. So, it is crucial to detect human stress and relaxation automatically via social media on a timely basis. It is very important to detect and manage stress before it goes into a severe problem. A huge number of informal messages are posted every day in social networking sites, blogs and discussion forums. This paper describes an approach to detect the stress using the information from social media networking sites, like tweeter.This paper presents a method to detect expressions of stress and relaxation on tweeter dataset i.e. working on sentiment analysis to find emotions or feelings about daily life. Sentiment analysis works the automatic extraction of sentiment related information from text. Here using TensiStrengthframework for sentiment strength detection on social networking sites to extract sentiment strength from the informal English text. TensiStrength is a system todetect the strength of stress and relaxation expressed in social media text messages. TensiStrength uses a lexical approach and a set of rules to detect direct and indirect expressions of stress or relaxation. This classifies both positive and negative emotions based on the strength scale from -5 to +5 indications of sentiments. Stressed sentences from the conversation are considered &categorised into stress and relax. TensiStrength is robust, it can be applied to a widevarietyofdifferent social web contexts. Theeffectiveness of TensiStrength depends on the nature of the tweets.In human being there is inborn capability to differentiate the multiple senses of an ambiguous word in a particular context, but machine executes only according to the instructions. The major drawback of machine translation is Word Sense Disambiguation. There is a fact that a single word can have multiple meanings or "senses." In the pre-processing part- of- speech disambiguation is analysed and the drawback of WSD overcomes in the proposed method by unigram, bigram and trigram to give better result on ambiguous words. Here, SVM with Ngram gives better resultPrecision is65% and Recall is 67% .But, the main objective of this technique is to find the explicit and implicit amounts of stress and relaxation expressed in tweets.

Authors: Kitjaroonchai Nakhon , Kitjaroonchai Tantip
Published: July 2023

Existing research has indicated the benefits of synchronous collaboration through Google Docs in enhancing language skills and productivity among learners. However, there remains a lack of knowledge concerning synchronous collaborative translation within the context of English as in Foreign Language (EFL) classrooms, particularly concerning its impact on the quality of students’ translations. This study aims to investigate the English translation skills of 20 English majors, aged between 18 and 23 years old, enrolled in the Faculty of Arts and Humanities at a private university in Thailand. The investigation compares individual translation with synchronous collaborative translation in small-groups, conducted under time constraints, utilizing three distinct tests. Additionally, the study examines the prevalent language errors made by individuals and small-groups during the translation process. The findings of the study reveal significant disparities between individual translation and collaborative translation in small- groups across all three test variations employed. Notably, the results suggest that engaging in collaborative work within small-groups leads to higher translation accuracy when compared to individual efforts. Regarding the identified errors, this study highlights word choice, mechanics, articles, prepositions, and ellipses as the most frequently occurring mistakes in both individual and small-group translations. This research briefly discussed the implications of the identified errors of collaborative translation in EFL classrooms.

Authors: Guo Xiaochuan
Published: July 2023

The psychological crises of university students are an important factor affecting the security and stability of colleges and universities. Against the background of school governance, the definition and characteristics of college students' psychological crisis events should be correctly understood and the legal risks clearly classified to help prevent crisis incidents. Legal risks have important practical significance. The author starts with the definition of college students' psychological crisis events and divides the characteristics into two parts: cause diversity and result sensitivity. The legal risks associated with the process are clearly divided into civil, administrative and procedural legal risks, which are specifically manifested in the duty of care in the prevention and response stages of the safety responsibility of colleges and universities. In the process, is there any infringement of privacy violations, and when an incident occurs, does the university take timely and positive measures and pay attention to protecting citizens’ legitimate rights and interests during the emergency response process? Are statutory after-care obligations such as diversion and guidance covered in the aftermath phase? Are students provided with reasonable and legitimate complaint channels?

Authors: Green Theresa , Goodridge Wade H. , Anderson Jon , Davishahl Eric , Kane Daniel
Published: July 2023

The purpose of this study was to examine any differences in test scores between three different online versions of the Mental Cutting Test (MCT). The MCT was developed to quantify a rotational and proportion construct of spatial ability and has been used extensively to assess spatial ability. This test was developed in 1938 as a paper-and-pencil test, where examinees are presented with a two-dimensional drawing of a 3D object containing a cutting plane passing through the object. The examinee must then determine the cross-sectional shape that would result from cutting along the imaginary cutting plane. This work explored three versions of this test (the original and two adapted versions), administered online, to see if there were any differences on the versions regarding student performance. Versions differed in the linework quality displayed as well as shading shown on the surfaces.

This study analyzed statics students’ scores on the three online versions of the MCT and on the original paper version of the MCT to identify which version of the test may be most optimal for administering to engineering students. Results showed that there was a statistically significant difference in students’ scores between multiple versions. Understanding which representations of the MCT items are most clear to students will provide insights for educators looking to improve and understand the spatial ability of their students.

Dikarenakan hal tersebut sehingga diperlukan penelitian yang bertujuan untuk mengetahui sirkulasi fluida pada induced draft counterflow cooling tower serta untuk mengetahui kemampuan pendinginan dengan standar temperatur air masuk adalah 70oC dan standar temperatur air keluar 27oC. Penelitian ini menggunakan metode pendekatan terstruktur atau kuantitatif dimana proses penelitian dilakukan dengan membuat design dan rancangan sistem pendingin yang kemudian cooling tower diidentifikasi melalui pengukuran dan  perhitungan. Berdasarkan  penelitian yang dilakukan mekanisme sirkulasi fluida pada induced draft counterflow cooling tower dimulai dengan air panas yang masuk ke dalam menara dikeluarkan melalui nozzle, dimana air yang jatuh akan pecah dan melambat saat melalui  filler. Pada saat yang bersamaan undara masuk melalui inlet dan melewati filler, uap panas akan ikut tertarik bersama udara dan air dingin akan jatuh kedalam kolam air dingin.  Cooling tower  mampu mendinginkan air dari tempertur 70oC ke temperatur standar air keluar 27oC dengan nilai rata-rata range 44,38oC dan rata-rata approach -0,67oC serta menghasilkan nilai Efektivitas mencapai 100% dan kapasitas penyerapan kalor maximum mencapai 225 kW.

Perancangan alat ini bertujuan untuk meningkatkan keamanan pada pintu serta untuk meningkatkan daya kreativitas, inovasi serta keahlian. Sistem ini menggunakan papan mikrokontoler Arduino yang berfungsi sebagai pusat kendali, sensor sidik jari digunakan untuk membuka kunci dari luar ruangan dan sensor ultrasonik digunakan untuk membuka kunci dari dalam ruangan, serta sistem ini dilengkapi dengan kunci konvensional sebagai pembuka kunci jika terjadi suatu masalah pada sistem. Hasil pengujian alat ini pada sensor sidik jari pengujian dilakukan menggunakan lima jari yang dimana tiga jari telah diregistrasi dan dua jari tidak diregistrasi. Dua jari yang telah diregistrasi dapat terbaca dan satu jari yang telah diregistrasi tidak terbaca, hal tersebut dapat terjadi karena beberapa faktor seperti jari sensor kotor, posisi jari tidak tidak tepat dan lain-lain. Pada sensor ultrasonik tidak terdapat masalah pada sensor tersebut. Alat ini memiliki kelebihan yaitu tingkat keamanan lebih tinggi dibandingkan dengan kunci konvensional biasa dan memiliki kunci konvensional sebagai cadangan jika terjadi suatu masalah pada sistem. Alat ini juga memiliki kekurangan yaitu harus selalu terhubung ke sumber listrik tetapi jika terjadi pemadaman listrik bisa menggunakan baterai. Beberapa komponen alat ini juga akan panas jika terus terhubung ke sumber listrik tetapi bisa diatasi jika menggunakan heatsink ataupun jenis pendingin lainnya.

Karakteristik aliran yang melewati struktur mempengaruhi stabilitas, desain aerodinamika dan respon struktur terhadap pola aliran yang melewatinya. Penelitian ini mengkaji secara numerik efek penggunaan pemecah aliran (splitter plate) terhadap pola kecepatan, tekanan, gaya aerodinamis dan deformasi aliran pada bilangan Reynolds 104. Penelitian ini menggunakan pemecah aliran tipe ganda 2D di sisi hilir dengan model turbulen k-ε menggunakan perangkat lunak ANSYS FLUENT 18.2. Hasil simulasi numerik menunjukkan bahwa penggunaan spliter plate telah merubah pola aliran yang melewati silinder persegi yang ditandai dengan berkurangnya zona negative aliran, pemulihan tekanan, dan penurunan gaya hambat. Pola deformasi aliran berbeda dengan silinder tanpa splitter plate. Data-data numerik juga ditampilkan dalam bentuk kontur aliran untuk memverikasi data grafis yang ditunjukkan pada studi ini. Studi ini juga menunjukkan bahwa penggunaan splitter plate juga menunjukkan sesintifitas grid yang berbeda dengan silinder persegi biasa, sehingga uji validasi-verifikasi sensitifitas grid silinder dengan splitter plat tidak direkomendasikan pada kasus yang serupa.
