Fungal-Associated Deterioration Of Polythene Bags Collected From The Dumping Sites Of District Sialkot: A Preliminary Screening Study, Zarish Fatima, Brian Gagosh Nayyar, Ayesha Sarwar, Mah-E- Noor Abbas, Saira Fiaz, Wajiha Seerat

Journal of Bioresource Management

Polythene bags are highly inert plastic materials made from monomers of ethylene. Due to their durability, lightweight, and low-weight characteristics, polythene bags are in high demand among consumers and retailers worldwide. This widespread use of polythene bags has led to the generation of polythene waste in the environment. This study focused on the degradation of polythene bags through fungal strains in the desired region.  In this research, three identified fungal strains, namely Aspergillus niger, Aspergillus flavus, and Fusarium oxysporum, were screened using two synthetic media for degradation, such as the culture plate method (CPM) and Liquid media degradation (LMD). A …

Correlation Of Norepinephrine With Some Biochemical Parametric In Patients With Type 2 Diabetes Mellitus, Aqeel Abed Nour Hadi, Ferdous A. Jabir, Muhammad Abd-Alwahab

Al-Qadisiyah Medical Journal

Background: Type 2 diabetes is a chronic metabolic disorder characterized by high blood sugar levels (hyperglycemia) resulting from the body's reduced ability to produce or use insulin effectively. Insulin is a hormone that regulates blood sugar levels, and in type 2 diabetes, the body either does not produce enough insulin or becomes resistant to its effects. This causes a buildup of glucose in the bloodstream, which can eventually harm organs and tissues. This study was carried out on patients who attended the Diabetes and Endocrinology Specialist Center of Marjan City for Medical Education in Babil Province; all patients were diagnosed …

Analysis Of Normalization, Resampling, And Weighted Voting To Improve K-Nn Performance In Diabetes Disease Detection, Agustiyar, R. Rizal Isnanto, Budi Warsito, Adi Wibowo, Ferry Jie

Research outputs 2022 to 2026

Diabetes is a global health issue, and machine learning has become crucial for early detection. The k-Nearest Neighbors (k-NN) machine learning algorithm is widely used because it is simple and easy to implement; however, its performance is sensitive to feature scale differences, class imbalance, and the assumption of uniform decision-making, as commonly found in clinical datasets such as the Pima Indians Diabetes (PID) dataset. Many studies have been conducted to address these issues; however, very few have systematically evaluated the combined effects of preprocessing and distance-based decision-making methods on k-NN performance. This study evaluates the combined effects of preprocessing strategies …

Hydroclimatic Whiplash Across The Contiguous United States: Characterizing Wet–Dry Transitions In Pdsi And Phdi, James Lam, Thomas Christopher Piechota

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Hydroclimatic whiplash, characterized by rapid transitions between wet and dry conditions, poses a growing challenge for water resource management and ecosystem stability. However, the spatial and statistical characteristics of wet–dry transitions across the contiguous United States are not fully understood. This study analyzed Palmer Drought Severity Index (PDSI) and Palmer Hydrological Drought Index (PHDI) records from 344 NOAA climate divisions spanning 1895–2024. Whiplash was defined as a transition between severe drought and severe wetness within 12-month rolling windows. Statistical descriptors including lag-1 autocorrelation, variance, and skewness were evaluated for whiplash and non-whiplash windows to assess differences between them. Whiplash hotspots …

Protecting Graduate Students From Burnout With Self-Compassion And Authenticity, Michael S. Leeman, Joshua J. Castleberry, Anna A. Ellenson, Morgan Wallbrown

Journal of Social, Behavioral, and Health Sciences

This study investigated whether practicing self-compassion and embracing one's authentic self could protect graduate students from burnout. Researchers also empirically examined the mediating effect of authenticity in the relationship between self-compassion and burnout. A total of 318 master's degree students in a helping profession completed surveys assessing their levels of self-compassion, authenticity, and burnout. Results found that graduate students with higher levels of self-compassion and authenticity tended to have lower levels of burnout. Additionally, authenticity mediated the relationship between self-compassion and burnout. The findings suggest that practicing self-compassion and embracing one's authentic self may lead to lower levels of burnout …
