Journal of Environmental Science and Sustainable Development

Municipal solid waste (MSW) management presents significant environmental challenges, especially with increasing urbanization and population growth. This study assesses the environmental impacts of MSW, focusing on waste composition, management practices, and their effects on air, water, and soil quality. The primary objective is to evaluate how MSW contributes to environmental degradation and to explore strategies for mitigating these impacts. A hypothesis was developed that optimizing waste composition through proper sorting and treatment can reduce the environmental footprint of MSW management by at least 10% in terms of leachate production and greenhouse gas emissions. Samples were collected using a randomized sampling …

Sustainable Cities In Developing Countries: A Case Of Balancing Cultural Heritage Preservation And Tourism In Manila, Philippines, Geoffrey Rhoel C. Cruz, Ma. Divina Gracia Z. Roldan

Asia-Pacific Social Science Review

This study argues that heritage can work side-by-side with development, with culture and heritage serving as an integral part of the city’s economic backbone. A major challenge faced by developing countries is making their cities sustainable by preserving cultural heritage amidst demands for economic growth. This is experienced in the Philippines, with its capital city, Manila, as a case in point. Using a heritage-driven development framework developed by Zerrudo (2020), the paper examines how cultural heritage conservation and tourism development objectives affect the sustainability of cities in developing countries.

Length-Weight Relationship And Condition Factor Of Three Cichlids From The Tono Dam, Ghana, Emmanuel O. Kombat, Elijah D. Angyiereyiri, Sandra A. Atindana, Elliot H. Alhassan

Tanzania Journal of Science

The length-weight relationship (LWR) and condition factor of three Cichlids, namely, Sarotherodon galilaeus, Coptodon zillii and Oreochromis niloticus from the Tono dam in Ghana, were investigated. A total of 1,870 individuals of the target species were randomly collected from 20 artisanal fishermen using gill nets to fish from January to December 2015. Each species was sorted by sex, and each fish's total length (L) and body weight (W) were measured and recorded. Simple linear regression plots of weight against length were computed, and the slope of the regression line, ‘b’ and intercept of the regression line, ‘a’ of each species …

Mathematical Analysis Of Monkeypox Transmission Dynamics With Control Strategie, Singo Juma Singo, Furaha Michael Chuma, Zubeda Seif Mussa

Tanzania Journal of Science

This study develops a mathematical model to analyze the transmission dynamics of Monkeypox and evaluate the effectiveness of control strategies. The model is formulated as a system of nonlinear differential equations, capturing key factors such as human-to-human transmission, zoonotic reservoirs, and control measures like vaccination, culling, personal hygiene and treatment. The model's equilibrium points, including the disease-free and endemic equilibria, are determined and analyzed for stability using the effective reproduction number, Re. Conditions under which Re<1 ensure the elimination of Monkeypox, while Re>1 indicates sustained transmission. A sensitivity analysis is performed to identify parameters that significantly influence Re​, such as the contact rate, effectiveness of control …

Assessing Potential Energy Sustainability Of Micro-Hydropower System Through A Sustainable Indicator Approach, Icmi Alif Safitri, Muhammad Sulaiman, Rachmawan Budiarto

Journal of Environmental Science and Sustainable Development

The development of micro-scale renewable energy power generation systems, such as micro-hydropower (MHP), often needs more consideration for sustainability during the planning stages. Many small-scale renewable energy systems have shorter-than-expected lifespans, jeopardizing Indonesia's Net Zero Emission Target for 2060 or earlier. Despite this, only some studies have examined the long-term viability of installed renewable energy generation projects, particularly MHP plants not managed by state-owned companies or PLN (Pembangkit Listrik Negara). The primary objectives of this research are to evaluate the feasibility of retrofitting and assess the potential sustainability of a decommissioned MHP in Banjarnegara, Central Java.

Journal of Environmental Science and Sustainable Development

The relocation of Indonesia's capital city is anticipated to promote inclusive economic growth while embracing cultural diversity. However, this transition may affect ultraviolet (UV) radiation exposure patterns. The study investigated variations in UV exposure in the IKN region, focusing on urban development factors such as land use and population density that affect public health, sun protection, and skin cancer prevention. The research hypothesized that UV radiation is significantly correlated with these factors. UV Index data from 2010-2023, a hierarchical clustering method, identifies complex data patterns without determining the number of clusters. XGBoost, a machine learning model, was used for handling …

Road Safety Assessment For Accident And Non-Accident Cases Supporting Sustainable Development Goals 2030, Brian Nararya Nugraha, Sekar Warangi Nurcahyati, Hizkia Adhikaratma, Martha Leni Siregar

Journal of Environmental Science and Sustainable Development

Halving the number of global deaths and injuries from road traffic accidents is one target of the Sustainable Development Goals 2030, which is still a challenging problem in Indonesia. However, the majority of research on this topic uses accident-based methods, which limits the safety analysis. Two road safety assessment methods are used to close the gap, with the addition of non-accident-based methods such as Road Safety Audits (RSA). The Margonda Raya Road, which is categorised as a traffic accident blackspot, was selected for the case study. For this, a field survey of the road segment is carried out. To minimise …

Exploring Antibiotic Resistance And Exopolysaccharide Production In Bacillus Paramycoides From Wastewater, Zainab Hassan, Nazia Jamil, Rida Batool

Journal of Bioresource Management

Antibiotics have been found extensively in the environment, particularly in groundwater, sediments, and surface water. The purpose of this study was to isolate and identify antibiotic-resistant bacteria from wastewater collected from sewage (Sher Shah Colony, Raiwind) and an industrial area (Hudiara Drain Gajju Matta) in Lahore. Ten bacterial strains (Z1, Z2, Z3, Z4, Z5, Z6, Z7, Z8, Z9, and Z10) were isolated from the samples. All of these strains were gram-positive. Antibiotic resistance profiling showed that strain Z1 was most resistant to ampicillin (1500 μg/ml) among all of the antibiotics (tetracycline, penicillin, erythromycin, and chloramphenicol) that were tested. A growth …

A Review On Wolbachia- A Viable Alternative To Control Aedes-Born Arboviral Diseases, Fatima Khizar, Iqra Mushtaq, Hafsa Masud, Muhammad Sajjad Sarwar

Journal of Bioresource Management

The endemic geographic ranges of mosquitoes are expanding due to various anthropogenic activities including rapid international travel and trade, urbanization, deforestation, and global warming. Hence, Aedes-borne arboviral diseases like dengue, chikungunya, yellow fever, or Zika infections would cause severe future outbreaks in non-endemic regions of the world. This threat to global public health highlights an urgent need for the development of efficient and effective mosquito control strategies. To date, a large number of mosquito vector-control strategies have been developed. Each of them has its strengths and weaknesses but the use of intracellular, endosymbiotic reproductive parasitic bacteria named Wolbachia pipientis …

Automated Segmentation Of The Ulnar Nerve In Mri Using Deep Learning Techniques, Akhil Nagulapalli

Theses

Cubital Tunnel Syndrome (CuTS), a condition caused by compression of the ulnar nerve, results in numbness, tingling, pain, and even muscle atrophy, affecting fine motor skills and diminishing patient quality of life. Accurate diagnosis of CuTS is challenging, as current diagnostic methods—including clinical exams, nerve conduction studies, and unaided MRI—often lack the precision to reliably identify the nerve and detect compression in its early stages. Deep learning-based segmentation offers a promising solution, enabling precise and automated identification of nerve structures in MRI images, which could significantly improve diagnostic accuracy and support timely intervention.

A novel deep learning model for segmenting …

Advancing Prediction Of Stimulant Medication Misuse Through Graph Representation Learning, Hamid Razavi
