In order to decisively determine the adsorption selectivity of zirconium MOF(UiO-66) towards anionic versus cationic species, the adsorptive removal of the anionic dyes(Alizarin Red S.(ARS), Eosin(E), Fuchsin Acid(FA)and Methyl Orange(MO)) and the cationic dyes(Neutral Red(NR), Fuchsin Basic(FB), Methylene Blue(MB),and Safranine T(ST)) has been evaluated. The results clearly reveal a significant selectivity towards anionic dyes. Such an observation agrees with a plethora of reports of UiO-66 superior affinity towards other anionic species(Floride, PO_4^(3-), Diclofenac sodium, Methylchlorophenoxy-propionic acid, Phenols, CrO_4^(2-), SeO_3^(2-), and AsO_4^-). The adsorption process of ARS as an example has been optimized using the central composite design(CCD). The resultant statistical model indicates a crucial effect of both pH and sorbent mass. The optimum conditions were determined to be initial dye concentration 11.82 mg.L^(-1), adsorbent amount 0.0248 g, shaking time of 36 min and pH 2. The adsorption process proceeds via pseudo-second order kinetics(R^2= 0.999). The equilibrium data were fit to Langmuir and Tempkin models(R^2= 0.999 and 0.997 respectively). The results reveal an exceptional removal for the anionic dye(Alizarin Red S.) with a record adsorption capacity of400 mg·g^(-1). The significantly high adsorption capacity of UiO-66 towards ARS adds further evidence to the recently reported exceptional performance of MOFs in pollutants removal from water.

This experiment aimed to determine how Cd exposure impacts CD4 cell activation,macrophage cells,pinocytosis activity,metallothionine expression,and Cd levels in juvenile Gambusia affinis gills.Four treatment groups were used,with one control and treatments A,B,C,and D at dosages of 0.03 mg/L,0.023 mg/L,0.015 mg/L,and 0.008 mg/L,respectively.The results showed that the number of CD4 with CD8 cell markers differed significantly from each treatment compared to the control(0.33%).The value in A,namely 0.54%,was the highest,followed by B,C,and D of 0.46%,0.44%,and 0.42%,respectively.The number of macrophages increased as the Cd level of the medium increased,as did the activity of pinocytosis.Furthermore,the immunofluorescence test on the gills with the Anti-MT Mouse and goat IgG fluoresce in Rhodamine on the gills showed that luminescence increased with increasing Cd levels in the gills.Similarly,the MT intensity increased at Cd-exposed gills as compared to the control.As the Cd level in the gills increased,the MT levels ascended significantly.

Farm location is an important factor in dairy farms, as it is closely associated with temperature and humidity that are crucial factors of influencing the physiological conditions and productivity of cows especially during the lactation period. The purpose of this study was to determine the effect of farm location on the physiological conditions and productivity of cows. The study was involved in 18 lactating Friesian-Holstein crossbreed cows in three farmer groups, i. e., Nangkasawit, Plalangan and Sumurejo. Temperature and humidity of the environment, rainfall and physiological conditions of cows (respiration rate, pulse, rectal temperature, total erythrocytes, hemoglobin and hematocrit) were observed. No influence (P > 0.05) of farm location on the parameters was observed, except for milk production (P < 0.05). In conclusion, farm location had no impact on the physiological conditions of Friesian-Holstein crossbreed cows in the district Gunungpati Semarang, Central Java, Indonesia.
