Geomorphological, Biophysical, and Photogrammetric Analysis of Agroforestry Systems Associated with Cacao (Theobroma cacao L.) Cultivation in the Dominican Republic 

Ender Iñiguez Freites,Ezequiel Echevarría Zamora,Agripina Ramírez Sánchez
This study takes a close look at the intricate connections between the shape of the land, ecological factors, and what we can see from above in cacao agroforestry systems in the Dominican Republic. We’re trying to figure out how the physical landscape influences where cacao grows and how much of it is produced. The research also delves into how things like soil composition, water availability, and climate patterns affect cacao productivity. To get a good handle on plant health, we use drones and...

He Dead Universe Theory (DUT): The Asymmetric Thermodynamic Retraction of the Universe and the Foundations of Cosmic Infertility

Joel Almeida
His article presents an extension of the Dead Universe Theory (DUT), intro-ducing two original conceptual frameworks: asymmetric thermodynamic retraction and the foundations of cosmic infertility. The central hypothesis is based on the growing imbalance between the declining rate of galaxy formation and the increasing prevalence of structurally exhausted galaxies. It is proposed that the universe is undergoing a non-explosive thermodynamic regression, governed by entropy rather than by expansion...

The Artistry and Singing Methods of Soprano Arias in Handel’s Vocal Works

Mila Wang
George Frideric Handel (1685-1759), as the most important composer of Baroque opera, wrote operas that were based on the early Italian opera experience in the Baroque style while incorporating various musical styles. Handel’s works represent the highest achievement of Baroque music creation. Among them, recitatives and arias are used throughout, and the natural, relaxed, soft and beautiful bel canto is performed with ease. The rhythm, melody, dynamics and the essence of the human voice are in pe...

Microplastics and Nanoplastics: Environmental Pathways, Ecological Impacts, and Regulatory Perspectives

Veera Shakar Pulusu,Srikanth Chilamula,Aditi Holkunde,Rajesh Gunturi,Pradeep Vidiyala,Sujith Raj Bashetty
A growing concern among the global population is the presence of Micro-plastics (MPs) and Nanoplastics (NPs) within various environmental compartments due to their pervasive, persistent presence. Through atmospheric, aquatic, terrestrial, and biological pathways, these particles enter and traverse ecosystems as a result of fragmentation of larger plastics and primary sources such as industrial abrasives and cosmetics. Since they are widely distributed, their presence in soil, freshwater, marine ...

Orientation of Drug Development: Focusing on Gene Expression Alterations, Giving up the Mechanisms of Action of Drugs

Gao-De Li
Many diseases are linked to abnormalities of gene expression patterns, and therefore, the study of drugs that alter gene expression patterns is important for improving these diseases. In pharmacology books, we cannot see the data of drug-altered gene expression patterns except the mechanisms of action of drugs. In this paper, we propose focusing on gene expression alterations and giving up the mechanisms of action of drugs.
