For accurate estimation of broiler chicken weight (CW), a novel hybrid method was developed in this study where several benchmark methods, including Particle Swarm Optimization (PSO), Genetic Algorithm (GA), Ant Colony Optimization (ACO), Differential Evolution (DE), and Gravity Search Algorithm (GSA), were employed to adjust the Random Forest (RF) hyperparameters. The performance of the RF models was compared with that of classic linear regression (LR). With this aim, data (temperature, relative humidity, feed consumption, and CW) were collected from six poultry farms in Samsun, Türkiye, covering both the summer and winter seasons between 2014 and 2021.

A series of sulfonamides incorporating a 1,2,3-triazolyloxime substituted 1,2,3-triazolyl moiety were conceptualized and synthesized as human carbonic anhydrase (CA) inhibitors. The synthesized small structures, denoted 7a through 7o, exhibited moderate inhibitory effects against the tumor-associated isoforms CA IX and CA XII compared to the well-known CA inhibitor acetazolamide. In contrast, these molecules demonstrated higher potency and a diverse range of selectivity against the cytosolic isoforms CA I and CA II.
