Authors: ABBAS Asaad A.
Published: July 2024

Abstract. The research paper endeavored to significantly improve the energy efficiency and sustainability of the electrode wear rate (EWR) in electric discharge machining (EDM) through a particular exploration of various parameters. These parameters included nano-powder concentration, electric current, and pulse-on time. By systematically analyzing and manipulating these variables, the study aimed to optimize the EDM process, thereby reducing energy consumption and enhancing the overall sustainability of the machining operation. We employed the Powder Mixed Electro-Discharge Machining (PMEDM) technique, a refined iteration of electric discharge machining. This innovative method blended graphite nano-powder with transformer oil to serve as the dielectric medium. The primary objective of this investigation is to examine the outcomes concerning crucial process parameters such as graphite powder concentration, electric current, and pulse-on time when machining high-speed steel, focusing mainly on electrode wear rate (EWR). Incorporating nano graphite (Gr) mixed powders into dielectric liquids has demonstrated a discernible enhancement in EWR across diverse operational conditions. The study found that the electrode wear rate (EWR) varied based on nano-powder concentration, electric current, and pulse-on time. Maximum EWR was observed at a concentration of 10 g/L, a current of 30 A, and a pulse-on time of 70 µs, while minimum EWR occurred at 0 g/L, 10 A, and 60 µs. The Full Factorial design, executed with MINITAB 17 software, validated these findings. The optimal EWR recorded was 1.154 mm3/min. The coefficient of determination (R-sq) for surface roughness prediction also stood at 91.15%.

Authors: Mohammed N.
Published: July 2024

Abstract. Addressing the increasing demand for energy in the Kingdom of Saudi Arabia (KSA) poses challenges and opportunities. This necessitates effective energy planning, diversification of energy sources, and implementation of energy-efficient technologies. This study presents the energy scenario in the KSA. Later, various technical algorithms used for energy prediction from past data, including regression models, statistical models, machine learning and deep learning networks, are presented. The present study revealed that learnable models, specifically neural networks, outperformed statistical and regression networks in predicting energy demands. In addition, statistical models lack predictability and lack adoption with new data.
AI-Based PV Panels Inspection using an Advanced YOLO Algorithm
Authors: HAERUMAN Agus
Published: July 2024

Abstract. The rapid growth of solar photovoltaic (PV) systems as green energy sources has gained momentum in recent years. However, the anomalies of PV panel defects can reduce its efficiency and minimize energy harvesting from the plant. The manual inspection of PV panel defects throughout the plant is costly and time-consuming. Thus, implementing more intelligent ways to inspect solar panel defects will provide more benefits than traditional ones. This study presents an implementation of a deep learning model to detect solar panel defects using an advanced object detection algorithm called You Look Only Once, version 7 (YOLOv7). YOLO is a popular algorithm in computer vision for classification and localization. The dataset utilized in this study was sourced from ROBOFLOW, consisting of 1660 infrared images showcasing thermal defects in PV panels. The model was constructed to identify a broader range of images with heterogeneity, leveraging the aforementioned dataset. Following validation, the model demonstrates a mean Average Precision (mAP) of 85.9%. With this accuracy, the model is relevant for real-world applications. This assertion is affirmed by testing the model with additional data from separate video-capturing PV panels. The video was recorded using a drone equipped with a thermal camera.

Authors: Ramírez-Díaz Marysol , Gutiérrez Jorge , Terrazas Teresa
Published: July 2024

Background and Aims: Systematic anatomy and leaf architecture have supported the separation of species by using leaf morphological and anatomical characters, such as, the arrangement of vascular bundles or the venation pattern. The genus Tilia (Malvaceae) consists of approximately 23 species with unclear boundaries between some of them.
Methods: The purpose of this work was to identify leaf morpho-anatomical characters that contribute to Tilia species differentiation. Leaves of eight species and four subspecies were collected studied. Leaf architecture was described using herbarium voucher and cleared-leaves and leaf anatomy through transverse and paradermal sections.
Key results: Results showed that leaves are variable in shape, margin dentate with first and second order teeth, secondary venation mostly craspedodromous and well-developed areole. Leaves were hypostomatic heterobaric and with three types of midvein. The combination of characters favored the recognition of species. For example, T. platyphyllos is characterized by teeth with narrower bases, T. mongolica is the only species with a deltoid lamina and without domatia and T. caroliniana subsp. occidentalis is separated by lamina with three teeth per cm and four-armed stellate trichomes with a length of 296 µm.
Conclusions: The different combinations of leaf characters are promising for the systematics of the genus Tilia.

Authors: Feofilov I. V. , Chernega V. S. , Arbuzov I. A.
Published: July 2024

Introduction. Currently, single- and multifactorial criteria are employed to evaluate the quality of urolithiasis treatment utilizing lithotripsy. Among the most utilized single factors that influence the efficacy of urolithiasis therapy are the stone-free rate (SFR), the duration of lithotripsy, the level of intra- and post-operative complications, and hospital stay following lithotripsy. A more promising approach is the integrated indicator of the efficacy of urolithiasis management using the lithotripter, which considers all the aforementioned factors. It is an urgent task to determine the extent to which alterations in individual variables impact the value of an integrated assessment of the efficacy of laser lithotripsy-based urolithiasis intervention.

Objective. To study the dependence of the integral efficiency indicator on the magnitude of influencing factors in the treatment of urolithiasis using transurethral thulium lithotripsy.

Materials & methods. We used the method of mathematical modeling of the integral criterion for urolithiasis treatment efficacy using the Scilab v.6.02 software package to determine the extent to which individual factors influence the overall effectiveness of laser thulium lithotripsy.

Results. Graphical dependences of the index of urolithiasis treatment efficacy for lithotripsy on the complication rate (at different values of surgery time and dependence of urolithiasis treatment efficacy on SFR at different values of complication rate, surgery time and hospital stay) were obtained. A software system for determining the integral index of urolithiasis treatment efficiency for lithotripsy was developed.

Conclusion. The resulting dependencies of the index of urolithiasis treatment efficacy for lithotripsy can be used to evaluate the impact of the complication grade and the SFR on the value of the efficacy index and to devise measures to enhance it. The software developed for the calculation of this index allows to obtain the required value at different input influencing parameters.

Published: July 2024

Introduction. In patients with suprapubic tube (SPT) surgical restoration of voiding is not 100% successful. Sometimes urination is inadequate or not recovered at all.

Objective. To determine factors influencing the outcomes of benign prostatic hyperplasia / benign prostate obstruction (BPH/BPO) surgery in patients with cystostomy drainage.

Materials & methods. The study included 52 men with suprapubic tube initially placed for urinary retention caused by prostate hyperplasia. Afterwards, all patients underwent transurethral resection of the prostate. The age of the patients ranged from 48 to 85 years old. Clinical and urodynamic data of the patients were analysed, restoration of adequate urination after surgery was evaluated as well. We took into account patients age, IPSS scores, bacterial growth in the urine culture test, number of episodes of urinary retention, volume of urinary retention prior to cystostomy, prostate volume, intravesical prostate growth, detrusor overactivity and ability to void in the presence of SPT.

Results. We were unable to achieve adequate bladder emptying after transurethral resection of the prostate in 4 (7.6%) patients. These patients required continued bladder drainage after surgery. In 48 (92.4%), adequate urination was restored after surgery and cystostomy drains were removed. Patients with one or more of the following characteristics were more likely to experience a failure of surgical treatment: age over 80, residual urine volume over 1500 mL, and absence of overactive bladder.

Conclusion. The study indicates that use of cystometry prior to BPH/BPO surgery is reasonable in such patients.  Feasibility of BPH/BPO surgery for this group of patients should be considered individually.

Published: July 2024

Background

Plastic pollution has reached an alarming magnitude, defining the contemporary era as the “Plastic Age.” Uncontrolled plastic production and inadequate recycling processes have led to widespread contamination of the environment with micro and nanoplastics.

Objective

The study aims to assess the environmental and human health consequences of exposure to microplastic particles (MPs) and their additives among plastic recycling workers in Dhaka. Specifically, it focuses on mapping the management pathways of plastic waste from collection to disposal, analyzing the types of MPs in the environment, and assessing the potential health impacts on plastic recycling workers.

Methods

A cross-sectional exploratory study design was used, consisting of exposed and nonexposed groups in plastic recycling sites in Dhaka, Bangladesh. The study will establish possible associations between different health consequences and microplastic particle exposure with a systematic approach involving plastic recycling hot spot detection, management pathway mapping, and detecting the presence of environmental MP. MPs and heavy metals will be detected from environmental samples using fluorescence microscopy, Fourier-transform infrared spectroscopy, and inductively coupled plasma mass spectrometry. Human exposure will be assessed by detecting the metabolites of bisphenol and phthalates from urine samples using liquid chromatography–tandem mass spectrometry and thoroughly evaluating endocrine, reproductive, respiratory, and renal functions. The sample size was derived from the mean concentrations of urinary bisphenol and phthalates metabolites, requiring the participation of 168 respondents. A 1:1 exposure to nonexposed stratification would be sufficient to meet our study objectives, considering the conventional level of power and confidence interval. This study protocol (PR#22111) has received approval from the Research Review Committee and Ethical Review Committee of the icddr,b.

Results

The project was funded in August 2022. We started collecting environmental samples in January 2023 and completed participant enrollment, exposure survey, and biological sample collection by December 2023. We enrolled 84 adult plastic recycling workers with at least 5 years of exposure history and 84 nonexposed participants who were not involved with plastic recycling activities. Data analysis is currently underway, and the first results are expected to be submitted for publication in November 2024.

Conclusions

The findings would provide valuable insights into the adverse impacts of microplastic pollution on both the environment and human health, aiding in better understanding the extent of the issue.

UNSTRUCTURED

The purpose of this paper is to demonstrate how critical discourse analysis (CDA) frameworks can be used in cross-cultural mental health recovery research. CDA is a qualitative approach that critically appraises how language contributes to producing and reinforcing social inequalities. CDA regards linguistic productions as reflecting, consciously or unconsciously, the narrators’ understandings of, or attitudes about, phenomena. Mental health recovery research aims to identify and address power differentials, making CDA a potentially relevant approach. However, CDA frameworks have not been widely applied to mental health recovery research. We adapted established CDA frameworks to our cross-cultural mental health recovery study. The adapted methodology comprises (1) selecting discourses that indicate positive changes and (2) considering sociocultural practices informed by relevant cultural characteristics identified in our previous research, without placing value judgments. Our adapted framework can support cross-cultural mental health recovery research that uses CDA.

Authors: Tesso Dessalegn wirtu
Published: July 2024

BACKGROUND

Abstract
Background: The rapidly evolving COVID-19 pandemic has become a global health crisis. However, as the CoVID-19 is a new pandemic infectious disease, how people, particularly young people, perceive self risks to COVID -19 and associated factors is not well understood .

OBJECTIVE

Objective: The general objective of this study was to assess the perceived self -risk perception; health behaviours related to CoVID-19 and associated factors among young people (18-24yrs) in selected Wollega zones

METHODS

Methods and materials: A community based cross sectional study design was conducted from July to August, 2021. The study was conducted in 10 selected districts of Horo Guduru Wallaga and East Wollega Zones (four from Horo Guduru Wallaga and 6 from East Wallaga Zone) and two zonal capitals, Nekemte and Shambu. The total sample size was 630 young people aged 18-24 years. This sample size was proportionally distributed to the selected study areas based on their population size. Data collection tool was developed from different literature in English and translated to Afan Oromo, the regional language, and was pretested on young people with similar demographic characteristics out of the study areas. Data collectors were recruited from each site and were trained for two days. Data was collected by house–to- house survey. Descriptive, covariate and multivariate analysis was done after data was cleaned for error.

RESULTS

Result: Almost all (99.7%) of the respondents have ever heard about corona virus and 97.1 % reported that they know the modes of transmission of corona virus. However, only less than fifty percent (46.6%) of the study participants mentioned droplet as major mode of transmission of corona virus. The majority knew the sign and symptoms of COVID-19 and that it is preventable. Age and awareness level of participants on the cause of CoVID-19 was significantly associated with self-risk perception.

CONCLUSIONS

Conclusion: Even though, almost all young people have ever heard about corona virus, there is a knowledge gap in the mode of transmission and prevention methods of Corona virus. Age and awareness level on the cause of CoVID-19 disease was positively associated with self-risk perception.

Published: July 2024

Hydrogels, or water-swollen polymers, are three-dimensional networks of polymeric chains with a high capacity for holding water inside their structure. Because of this special quality, they are helpful in many applications, such as tissue engineering, drug delivery, and wound healing. Tissue engineering, controlled drug release, smart devices, and magnetic fields are all made possible by their sensitivity to temperature, ionic strength variations, electric fields, pH changes, magnetic fields, and ultrasounds. The interesting potential of stimuli-dependent hydrogels for gastroretentive drug delivery in the Gastrointestinal Tract (GIT) is examined in this review article. A new strategy is provided by stimuli-responsive hydrogels, which change their characteristics in response to particular GIT environment triggers like pH, enzymes, or pressure. The article explores a range of stimuli-dependent hydrogels, such as those that react to enzymes, pH, and other stimuli. Hydrogel's latest developments and their use in GIT medication delivery are also examined. Promising research on these innovative drug delivery systems is highlighted in the review. The paper also examines patents about stimuli-dependent hydrogels, offering information about the intellectual property environment surrounding this technology. In summary, hydrogel systems combine the targeted response to GIT stimuli with the controlled release properties of hydrogels to hold immense potential for improved drug delivery and therapeutic efficacy.

Peringkasan teks merupakan salah satu cara untuk mengurangi suatu dimensi dokumen yang besar untuk mendapatkan informasi penting dari dokumen tersebut. Berita adalah salah satu informasi yang biasanya dalam satu topik memiliki beberapa sub topik. Untuk dapat mengambil informasi penting dari satu topik secara cepat, peringkasan multi dokumen berita dapat menjadi solusi. Namun, peringkasan multi dokumen dapat menimbulkan redundansi. Oleh sebab itu, penelitian ini menerapkan algoritma cluster importance dengan mempertimbangkan posisi kalimat untuk mengatasi redundansi tersebut. Penelitian ini menggunakan 30 topik berita berbahasa Indonesia, dimana tiap topiknya terdiri dari 5 sub topik berita. Dari 30 topik berita yang diuji menggunakan Rouge-1, dimana terdapat 2 topik berita yang memiliki nilai Rouge-1 berbeda antara yang menggunakan algoritma cluster importance ditambah posisi kalimat dengan yang hanya menggunakan algoritma cluster. Namun dari 2 topik berita tersebut, nilai Rouge-1 yang menggunakan cluster importance ditambah posisi kalimat memiliki nilai yang lebih besar daripada yang hanya menggunakan cluster importance. Penggunaan posisi kalimat memiliki pengaruh terhadap urutan bobot kalimat pada setiap topiknya, namun hanya 2 topik berita yang berpengaruh terhadap hasil ringkasan.

Seiring berkembangnya jaman perkembangan malware android terus mengalami peningkatan setiap tahunnya.Machine Learning adalah salah satu teknik yang bisa kita gunakan dalam melakukan analisa malware android dengan 2 model pendekatan statis dan dinamis.Penulis menggunakan Support Vector Machine(SVM) untuk proses klasifikasiannya dan menggunakan kernel RBF. Fitur yang digunakan dalam penelitian ini adalah Permission dan Broadcast Receiver. Untuk menambah hasil akurasinya digunakan metode Seleksi Fitur Relieff. Dan Seleksi Fitur pembandingnya adalah Chi-Square(CHI),Correlation-based Feature Selection(CFS), dan Gain Ratio(GR). Hasil dari Seleksi Fitur Relieff akan di evaluasi dengan Seleksi Fitur pembandingnya serta juga dengan hasil klasifikasi tanpa menggunakan Seleksi Fitur. Akurasi klasifikasi Seleksi Fitur Relieff menghasilkan 33.33333%, hasil akurasi Seleksi Fitur pembanding lainnya juga memberikan hasil sama dengan Seleksi Fitur Relieff. Sedangkan hasil klasifikasi tanpa Seleksi Fitur memberikan hasil yang cukup tinggi yaitu 95%. Hasil pengujian menunjukkan bahwa Seleksi Fitur tidak cocok digunakan dengan data yang sedikit karna memberikan hasil yang jauh lebih rendah dari tanpa menggunakan Seleksi Fitur.
