Research Progress On Detection Technologies For Florfenicol Residues In Animal-Derived Foods, Hu Xiaofei, Ge Mengjun, Wang Yao, Cai Wenjin, Xing Guangxui

Food and Machinery

As a broad-spectrum antibiotic, florfenicol is widely used in livestock, poultry and aquaculture. Due to the unregulated use by some enterprises, a large amount of florfenicol residue exists in animal-derived foods. When florfenicol enters the human body through the food chain, it can cause gastrointestinal discomfort, intoxication, and even aplastic anemia. To minimize the effects of florfenicol residues and derivatives in food on human beings, many countries have set strict limits for maximum florfenicol residues in food. Therefore, this paper summarizes the detection methods for florfenicol established in recent years and gives an outlook on their development trends.

Turkish Journal of Mathematics

A fifth-order trigonometrically-fitted explicit two-derivative Runge–Kutta–Nyström method with an adaptive step size strategy, denoted as ATFRKN5, is proposed for efficiently solving second-order ordinary differential equations of the form u^″(x) = f(x, u(x)) that exhibit oscillatory behavior. The order conditions of the method are derived using Taylor series expansion, enabling the construction of two-derivative Runge–Kutta–Nyström schemes up to orders four and five.

Proportion Of Nilpotent Subgroups In Finite Groups And Their Properties, João Victor Monteiros De Andrade, Leonardo Santos Da Cruz

Turkish Journal of Mathematics

​This work introduces and investigates the function J(G) = Nil(G) / L(G) , where Nil(G) denotes the number of nilpotent subgroups and L(G) the total number of subgroups of a finite group G.

The differential equation is considered under Samarskii Ionkin-type boundary value conditions with respect to the spatial variable x. Necessary optimality conditions are derived, and the associated nonlinear functional equations are analyzed. Using the contraction mapping principle, the existence and uniqueness of the control function are established. Subsequently, the redefinition function and the state function are determined. The convergence of their respective Fourier series representations is rigorously proven.
