Kittichai Chantima — 2025-05-12

The application of pesticides in agricultural practices, particularly in rice cultivation, has significant impacts on freshwater ecosystems and poses risks to the survival of various aquatic organisms. This study aimed to evaluate the acute toxicity of the pesticide diazinon on juvenile Nile tilapia (Oreochromis niloticus) and freshwater prawns (Macrobrachium lanchesteri). A static bioassay was conducted to determine the concentration causing 50% mortality within 96 hours (96hr-LC₅₀), and the data were analyzed using probit analysis. The results revealed that the 96hr-LC₅₀ values for juvenile Nile tilapia and freshwater prawns were 14.67 and 1.39 ppm, respectively. These findings can be utilized to establish safe concentration thresholds of diazinon in natural water bodies, providing essential data for ecological risk assessment and supporting the formulation of environmentally sustainable pesticide management strategies in agriculture.

On The Exponential Diophantine Equation (4n-1)^x +63^y =z^2 where (4n-1) is Prime

Napatsakorn Kasiphan — 2025-07-04

In this paper, we study the exponential Diophantine equation (4n-1)^x +63^y =z^2 where (4n-1) is prime. We found that all non-negative integer solutions are of the following (n,x,y,z)\epsilon \left\{ (1,1,0,2),(1,4,1,12),(8,2,1,32)\right\}\cup \left\{(n,0,1,8)\right\}\cup \left\{ \left ( \frac{63^m+1}{2},1,2m,63^m+1 \right )\right\}, where n,m are positive integers x,y and z are non-negative integers. In the proof, we apply reasonably Catalan's conjecture and various theorems concerning the congruence to obtain the solution.
