Electrolyte abnormalities are among the most common reasons for patients to develop cardiac arrhythmias. Of all the electrolyte abnormalities, hyperkalemia is most rapidly fatal. A high degree of clinical suspicion and aggressive treatment of underlying electrolyte abnormalities can prevent many patients from progressing to cardiac arrest.

During the initial stages of leaf and needle litter decomposition, microorganisms face nitrogen (N) phosphorus (P) scarcity since plant is very N- P-poor compared to microbial biomass. The processes that use cope with unfavorable stoichiometry, such as transport nutrients into decomposing litter, are still not fully understood. aim study was explore import release (N, P, K, Mn, Ca, Mg) from Nor...

Human use of freshwater resources has altered the dynamics of hydrologic regimes in rivers around the world. Frequency, timing, and periodicity of extreme fluctuations in water flow have been modified, disrupting the flow regimes to which lotic biota have adapted over evolutionary time. The goal of the proposed research is to increase our understanding of how the hydrologic regime modulates lin...

Ultramafic (UM) rocks are defined as igneous that contain more than 90% of mafic minerals. Soils derived from ultramafic rock generally nutrient-deficient and have concomitant high concentrations potentially phytotoxic trace elements (Ni, Cr, Co, Mn). Consequently, to assess the dynamics nutrients metals in complex Niquelândia (Brazil), soil solutions been sampled soils characterized by Cr(VI) ava...

Increased nutrient loading in aquatic environments can have a long-lasting influence on ecosystem processes and functions. The Kootenai River was historically oligotrophic, but nitrate levels been steadily increasing since the mid-2000s, while phosphorus remained low. Our study objective to evaluate current distribution throughout watershed context of land use cover change. Each three types we ...

this research was conducted to study the nutrient balance condition of dairy cattle in semi industrial dairy farms of sought west of tehran province (eslamshahr) by the questionnaire techniques. the farms based on the herd were categorized in 6 group as follows: 1(1-30), 2(31-60).3(61-100), 4(100-130), 5(130-200) and 200 heads upward. the 30 farms have been selected randomly based on the random...

We report results from a series of studies coevolving players for simple Rock–Paper–Scissors games. These results demonstrate that “Current Individual versus Ancestral Opponent” (CIAO) plots, which have been proposed as a visualization technique for detecting both coevolutionary progress and coevolutionary cycling, suffer from ambiguity with respect to an important but rarely discussed class of...

Ingesting nutritionally imbalanced food can cause a significant reduction in fitness in insects. Insects can avoid the negative consequences of nutritional imbalances by selectively foraging for nutritionally complementary foods. We investigated the ability of the omnivorous beetle, Tenebrio molitor (Coleoptera: Tenebrionidae), to redress nutritional imbalances by selecting complementary foods....

We evaluated the consequences of nutritional imbalances, particularly lipid/nitrogen imbalances, on wine yeast survival during alcoholic fermentation. We report that lipid limitation (ergosterol limitation in our model) led to a rapid loss of viability during the stationary phase of fermentation and that the cell death rate is strongly modulated by nitrogen availability and nature. Yeast surviv...
