Why livestock animals don't eat lupinus species?
5 answers
Livestock animals may avoid consuming Lupinus species due to the presence of antinutritional factors like quinolizidine alkaloids, which can be toxic and teratogenic to them. These alkaloids, along with other factors like non-starch polysaccharides and oligosaccharides, can hinder the utilization of lupine seeds in monogastric animal feeds. Although lupins are a valuable protein source, their high levels of anti-nutritional factors have limited their use in pig diets, despite efforts to breed varieties with improved digestibility and lower antinutritional contents. However, strategies such as dehulling lupine seeds have been shown to enhance their nutritional composition, making them comparable to soybean by-products in supporting livestock production and improving animal product quality.
Doed lithium carbonatye react with organic solvents
5 answers
Lithium carbonate does not react with organic solvents. However, lithium does react with various organic solvents commonly used in lithium-ion batteries, such as tetrahydrofuran (THF) and propylene carbonate (PC). Highly concentrated solutions of lithium perchlorate in organic solvents have been utilized for synthetic transformations due to the mild Lewis acidity of the lithium ion in donor solvents like diethyl ether. Theoretical investigations have shown that cyclic carbonate electrolytes in lithium-ion batteries form complexes with lithium that contribute to high performance by constructing a solid electrolyte interface and enhancing Li ion conductance. Organolithium reagents interact with coordinating solvents like HMPA, forming contact ion pairs, but lithium carbonate specifically does not partake in such reactions.

Analysis of wild bird feeders?
5 answers
Wild bird feeders play a significant role in studying bird behaviors and disease transmission. Automated feeders provide detailed data on feeding patterns and environmental interactions. While popular among hobbyists, bird feeders can potentially facilitate disease transmission among wild birds. Studies in Poland found no presence of zoonotic Salmonella spp. in bird feeders, attributing this to low bacterial shedding by infected birds and poor bacterial survival in feces. However, feeders can harbor pathogens like Salmonella enterica Typhimurium, highlighting the importance of understanding disease dynamics and risks associated with feeding practices. Varied effects on avian health were observed, with feeding influencing parasite infection parameters and body condition in different bird species. Overall, managing disease risks and promoting bird health are crucial considerations for those engaging in wild bird feeding activities.
How long dose zinc supplimention need to treat zinc deficincy?
4 answers
Zinc supplementation duration for treating zinc deficiency varies based on the specific condition. In cases of transient zinc deficiency in breastfed preterm infants, a 15-week-old baby girl showed complete healing of zinc deficiency-related lesions after a two-week trial of oral zinc supplementation at 3 mg zinc gluconate/kg body weight/day, with treatment withdrawal at six months of age. However, in a study evaluating different doses and frequencies of zinc supplementation in children aged 9-11 months, the interventions over a 24-week period did not effectively reduce diarrhea incidence, indicating that longer durations or different dosages may be needed for zinc supplementation to treat diarrhea effectively. Therefore, the duration of zinc supplementation for treating zinc deficiency can range from a few weeks to several months, depending on the specific circumstances and conditions being addressed.
What is the chemical formula for converting isotópica values from calcite to aragonite?
5 answers
The chemical formula for converting isotopic values from calcite to aragonite involves an enrichment in heavy isotopes in aragonite compared to calcite, indicating aragonite precipitation from isotopically heavier solutions. Additionally, dolomite displays higher δ18O values but lighter δ13C values, possibly due to organic activity during its formation. The equilibrium curve for calcite-aragonite transformation can be expressed as P = 5500 + 12.6T, where pressure (P) is in bars and temperature (T) is in degrees Celsius. Experiments show that aragonite can readily convert to calcite under heating and mechanical stress, with changes in δC and δO showing a linear correlation during mineral structure alteration. A proposed model for the aragonite-calcite transition suggests a dislocation mechanism leading to topotactic relationships between the two minerals.
