Published: July 2023

Background:
The brain-type natriuretic peptides (BNP) and troponins levels can be used for the risk stratification of patients presenting with acute myocardial infarctions. Elevated levels of N-terminal pro-brain natriuretic peptide (NT-ProBNP) can be seen in patients with heart failure (HF) and atrial fibrillation.

Objectives:
The aim is to evaluate the NT-ProBNP levels and high-sensitive troponin-T (Trop T-HS) levels in patients with ischemic and nonischemic HF and to analyze its association with prognosis.

Methods:
This prospective observational study was conducted in a tertiary Centre over a period of 2 years. We analyzed NT-ProBNP and Trop T-HS levels of patients with HF, who were admitted to our cardiac intensive care unit. Patients with acute coronary syndrome, myocarditis, and renal failure were excluded from the study. The study population consists of 130 patients, of which 90 patients with ischemic dilated cardiomyopathy (ISDCM) and 40 patients with idiopathic dilated cardiomyopathy (IDCM). They belonged to the New York Heart Association functional classes 3 and 4. The diagnosis was made with the help of a coronary angiogram and transthoracic echocardiogram. We analyzed the NT-ProBNP levels and Trop T-HS of both groups of patients.

Results:
Males were predominant in both groups, i.e., 70 (77.8%) in the ISDCM patients and 26 (65%) in the IDCM patients. The NT-ProBNP levels were significantly higher among patients with ISDCM compared to patients with (IDCM) dilated cardiomyopathy (8648 ± 6207 pg/mL vs. 3100 ± 2906 pg/mL); P = 0.0008. We analyzed the NT-ProBNP levels of the survivors and nonsurvivors in each group separately. We found that there were significant differences in the levels of NT-ProBNP in the survivors and nonsurvivors in the ISDCM group (7061 ± 3663 vs. 18035 ± 4667 pg/mL); P = 0.0004. However, there was no significant difference between the survivors and nonsurvivors of IDCM patients (4701 ± 737 vs. 6821 ± 1212 pg/mL); P = 0.07. Like the previous analysis, higher levels of Trop T-HS levels were found in patients with ISDCM group compared with IDCM group (26.6 ± 8.5 ng/L vs. 16.3 ± 3.4 ng/L); P = 0.0002. There was also a significant raise of Trop T-HS in the nonsurvivors in the ISDCM group compared to the survivors (28.9 ± 16.3 vs. 65.5 ± 17.0 ng/L): P = 0.0003. Conclusion: In this study, we found that HF patients who were admitted with higher levels of NT-ProBNP and Trop T-HS had a poor prognosis.

Published: July 2023

Introduction:
An impacted tooth is one that remains unerupted and/or is partly erupted due to mechanical obstructions. These teeth can give rise to a magnitude ranging from dental caries, tumors, periodontal diseases to even jaw fractures.

Materials and Methods:
The study aimed to identify and analyze the impaction of maxillary and mandibular canines, premolars, and molars among children and adolescents aged 13 to ≤21 years of Indian origin belonging to both sexes who reported orthodontic treatment having good quality radiographs and medical/dental case sheets. The Pearson’s Chi-square test analyzed the data obtained. Level of with a significance was set at P < 0.05.

Results:
Of 1001 individuals (551 M, 450 F), we could detect 709 individuals with impaction. The prevalence of impaction of third molar, canine, and premolar was found to be 29.1%, 31.4%, and 10.3%, respectively. Molar and canine impactions were more common in males, while premolar impactions were observed more in females.

Conclusion:
The prevalence of third molar impaction, canine impaction, and premolar impaction was found to be 29.1%, 31.4%, and 10.3%, respectively. Molar and canine impactions were more common in males, while premolar impactions were observed more in females among the patients reported for orthodontic treatment.

Published: July 2023

Introduction:
Behçet’s disease (BD) is a rare inflammatory autoimmune disorder characterized by recurrent oral and genital ulcers, uveitis, and other systemic manifestations. Reported neurological manifestations of BD include meningoencephalitis, cerebral venous thrombosis, intracranial hypertension (ICH), and cranial nerve palsies. Involvement of the superior vena cava (SVC) is rare but should be considered in patients with BD with suspected ICH.
Case Report:
A 32-year-old man presented with ICH as the initial manifestation of BD. He presented with a one-week history of facial and neck edema, headache, and blurry vision, followed by fever, sore throat, and oral blisters a few days later. Lumbar puncture (LP) was performed, and opening pressure was found to be elevated at >50 cmH2O and closing pressure of 36 cmH2O. The work-up included a chest CT, which identified thrombosis of the SVC extending into the brachiocephalic veins, and blood work which revealed elevated inflammatory markers. Further probing revealed a history of genital ulcers and a family history of a cousin with BD. The patient underwent mechanical thrombectomy and was treated with oral prednisone with symptom resolution.
Conclusion:
BD has a wide spectrum of symptomology and may present without common manifestations, making it challenging to diagnose. The aim of our report was to emphasize the importance exploring the rarer vascular, neurological, and cardiac symptoms of BD in order to avoid potentially dangerous sequala. A system approach may be necessary to diagnose and optimally treat these patients.

Deaf and hearing-impaired people typically use sign language as their primary form of communication. This study designed a Convolutional Neural Network-based Sign Language e-tutor which removes language barriers between people who are deaf and use sign language and people who can hear and speak. Thus giving deaf people a way to communicate with hearing people in real time, with no need to write notes or use a human sign language interpreter. The method used is comprised of four major phases: data collection, data preprocessing, model training and model evaluation. The Model Precision, Accuracy, Recall and f1 score were 0.977, 0.985, 0.99, and 0.99 respectively.
Influence of Ammonium Chloride Buffer Solution on the Photo-Electro-Chemical (PEC) Cell and Optical Performance of Mos2 Thin Films
Authors: Olusola Olajide I 
Published: July 2023

Thin films of molybdenum disulphide (MoS2) of approximately same thickness of 290 nm have been successfully synthesized with and without ammonium chloride (NH4Cl) buffer solution using electrodeposition growth technique. The experimental results obtained showed that NH4Cl buffer solution has an obvious effect on the photo-electro-chemical (PEC) cell and optical performance of electrodeposited MoS2 (ED – MoS2) thin films. The MoS2 thin films prepared from NH4Cl buffer solution possess better electronic properties than the ones prepared without the buffer when measured under dark condition. Open circuit voltage of ~0.556 V and ~0.382 V were obtained for samples prepared with and without a buffer solution respectively. MoS2 from buffer solution had higher maximum power (Pmax) of 0.710 mW while the ones without a buffer solution had a Pmax value of 0.258 mW Also, both materials showed different electrical conductivity type possibly due to the influence of chlorine in the prepared electrolytic bath. The optical results revealed similarity in the energy band gaps of both materials with a little variation. In the same vein, both MoS2 thin films showed optical conductivity of same order but MoS2 thin films prepared with buffer solution have higher magnitude than the ones without a buffer solution. These preliminary results revealed that more efficient MoS2 films for photovoltaic application can be developed / deposited using an electrolytic bath containing NH4Cl buffer.

Published: July 2023

Fuzzy Time Series (FTS) is able to eliminate the problem of overfitting that is fundamental to Artificial Neural Network (ANN), hence this study used air pollution data acquired from three different sampling stations in Kaduna metropolis, Nigeria, to implement FTS using the Adaptive Neuro Fuzzy Inference System (ANFIS). The fuzzy inference system (FIS) was generated by the ANFIS model using grid partitioning and subtractive clustering optimization types with backpropagation and hybrid training algorithms. The models were implemented using MATLAB 2018b software, and a total of thirteen models were developed. The resulting models were used to forecast the daily mean for the next ten days for each sampling station and for each pollutant. Carbon monoxide (CO), Nitrogen dioxide (NO2), Sulfur dioxide (SO2), Particulate matter, (PM2.5 and PM10) air pollutants were considered. Determination of the accuracies of the developed models in forecasting the next ten days was achieved using the error performance metrics of Mean Absolute Error (MAE), and Root Mean Squared Error (RMSE). The results of the performance metrics from the models in the same category are correlated and indicated similar trends. Comparison and analysis of the models revealed the one with the most accurate prediction for each sampling station and pollutant.

Following the rapid growth of cities,the continuous expansion of cities, too many vehicles competing for limited capacity transportation, Researchers on a daily basis are working tirelessly to solve the problem of road traffic congestion as it increases the increasing probability of accidents and has a negative impact on the environment. In this paper, we focused on MATLAB as it is far better (financially) than using commercial tools for traffic simulation adopting a Simulated annealing algorithm. We created an objective function which in turn generated the fitness or best values using the equation: f = inline 20(C1)4 + 16(C2)2., while the traffic model consisted of 14 radio buttons, 12 text boxes and edit boxes) splitting into a cross road and adjoining T-junction separated by a distance to make it coordinated. After the signal time cycle, there were six (traffic) phases, each showing the decongestion time and fitness function. In Case 1, the decongestion time was within the range of 9s and 41s, while the second’s was within the range of 2s and 58s. Further analysis revealed the relationships between generated fitness values and decongestion times. Another table was designed to show the analysis of the lanes’ decongestion times, the phases and cycles involved. It was shown that the six lanes were touched in at most two phases in the two cases considered. In future, researchers should compare the theoretical values to real-life cases, and include emergency conditions (ambulance & police vans).

Published: July 2023

E-Wallet applications in Indonesia have started to be in demand since the Covid-19 pandemic. The object being analyzed is an e-wallet application that is widely used in Indonesia and can be downloaded on the Google Playstore. The applications analyzed are Dana, Ovo, PayPal Link Aja and Doku. The advantages of these five applications are that Dana is user friendly or easy to use, while using Ovo is superior in terms of benefits, and Doku is superior in terms of security, Link Aja tends to be perceived by consumers in a neutral condition between security and user convenience because it is an e-wallet. It is still considered new in Indonesia, and PayPal has become a successful online payment system in C2C field. The focus of this research is to compare the comments of the users of the five applications. The method used in this study is the Support Vector Machine (SVM) algorithm. To produce high accuracy it is optimized using the Particle Swarm Optimization (PSO) algorithm. This was taken based on previous studies which stated that SVM-PSO has the highest percentage of accuracy compared to other algorithms. The data used is a thousand (1000) per application. So, the total amount of data is five thousand (5000) data. The results of the research show that the Ovo e-wallet is superior because it has the most positive comments, namely 579 and 421 negative comments, while the lowest position is occupied by Link Aja which only has 579 positive comments and 421 negatuve comments. In the process of sentiment analysis, the accuracy percentage of the SVM-PSO algorithm was also obtained, which was 91.10% in the Link Aja application. This means that SVM-PSO is very suitable to be combined to get the highest accuracy

Metode Penerapan Dan Pengembangan Qowa`id Al-Ahkam
Authors: Lidinillah Endin 
Published: July 2023

Walaupun sudah ada pengembangan dalam berbagai hal terkait hukum Islam, namun dalam bidang qawa`id al-ahkam (kaidah-kaidah hukum Islam) pengembangan itu belum begitu tampak. Padahal pengembangan kaidah fikih yang belum mapan sangat diperlukan. Apalagi kalau kaidah fiqh itu didudukan sebagai bagian dari epistemologi hukum Islam yang membahasa bagaimana cara pembentukan dan perolehan hukum Islam, maka pengembangannya merupakan keniscayaan, karena akan sangat menentukan kemampuan hukum Islam sebagai produknya dalam merespon perubahan sosial yang sangat pesat akibat kemajuan teknologi saat ini. Penelitian pustaka (library research) ini menelusuri permasalahan metode penerapan dan pengembangan qawa`id al-ahkam tersebut. Hasil penelitian ini menyimpulkan bahwa dalam menerapkan qawa`idul ahkam, setidaknya ada tiga hal yang perlu diperhatikan agar tepat penggunaannya. Ketiga hal tersebut adalah: (1) kehati-hatian dalam penggunaannya; (2) ketelitian dalam mengamati masalah-masalah yang ada di luar kaidah yang digunakan; dan (3) memerhatikan sejauh mana kaidah yang di¬gunakan berhubungan dengan kaidah-kaidah lain yang mempunyai ruang lingkup yang lebih luas. Adapun qawa`id al-ahkam yang perlu dikembangkan dan dikaji ulang mencakup: (1) kaidah-kaidah fikih yang masih diikhtilaf¬kan di kalangan para ulama, yaitu kaidah-kaidah fikih yang masih diper¬debatkan baik substansinya maupun formulasinya, apakah akan men¬jadi kaidah fikih yang mapan atau akan hilang dalam kesejarahan dan keilmuan Islam; (2) kaidah yang sudah ada dan bisa diterima oleh mayoritas ulama, akan tetapi masih mungkin dikritisi untuk penyem¬purnaannya, baik kaidah umumnya, kaidah khususnya, atau kaidah tafshiliyah-nya; (3) memunculkan kaidah-kaidah fikih yang baru karena kebutuhan masyarakat telah jauh berkembang.
Mineralogy and mineral chemistry of detrital platinum-group minerals and gold particles from the Elbe, Germany
Authors: Junge Malte , Goldmann Simon , Wotruba Hermann 
Published: July 2023

Abstract. In heavy mineral concentrates of the Elbe, gold and
platinum-group minerals (PGMs) are observed. Two fractions (> 63
and < 63 µm) of the concentrate are analyzed by
reflected-light microscopy, scanning electron microscopy with automated
mineralogy software and electron microprobe analysis (EPMA). Other heavy
minerals are cassiterite, ferberite, monazite, uraninite,
columbite–tantalite, magnetite, zircon and cinnabar. Scanning electron
microscopy determined the modal abundance of PGMs, gold and the other heavy
minerals. The PGMs are mainly Os–Ir–Ru–(Pt) alloys, Pt–Fe alloys, sperrylite
and rustenburgite. Compositional variation of PGMs and gold was analyzed by
EPMA. This showed that Pt–Fe alloys are (1) native platinum (> 80 atom %), (2) ferroan Pt (20 atom % to 50 atom % Fe), (3) isoferroplatinum (2.64 to 3.04 apfu of sum PGE, platinum-group
element), (4) tetraferroplatinum group with Ni + Cu + Fe ≈ 50 atom %, and (5)
γ(Pt,Fe) with sum PGE > 3.04 apfu. The Os–Ir–Ru–(Pt)
alloys show large compositional variations. Platinum and Fe enrichment is
typically observed for Ir-rich Os–Ir–Ru alloys. Gold particles often show
compositional zoning of Ag-rich cores and Ag-poor rims due to selective
leaching of Ag. Similarly, Hg-rich rims of gold particles are analyzed.
These are interpreted as the results of in situ amalgamation due to mobilization of
Hg from the associated cinnabar particles. The size and shape of the gold
particles generally argue for short transportation distances. Similarly,
almost euhedral sperrylite and Pt–Fe alloys suggest a source region close to
the sampling site. However, roundish Os–Ir–Ru–(Pt) alloys presumably have
experienced longer transportation in the river. Gabbroic dikes of the
Lusatia block contain sperrylite and gold particles, which can be the source
for these particles found in the concentrate. The composition of the
Os–Ir–Ru–(Pt) alloys is similar to previous studies on the Vestřev
placer in Czech Republic. Both locations are within the drainage area of the
Elbe and can therefore be the source of the PGM and gold particles in
the concentrate.
