In this paper we highlight the connection between Ramanujan cubic polynomials (RCPs) and a class of polynomials, the Shanks cubic polynomials (SCPs), which generate cyclic cubic fields. In this way we provide a new characterization for RCPs and we express the zeros of any RCP in explicit form, using trigonometric functions. Moreover, we observe that a cyclic transform of period three permutes t...

Methylation-induced transcriptional silencing of the fragile X mental retardation-1 (Fmr1) gene leads to absence of the gene product, fragile X mental retardation protein (FMRP), and consequently fragile X syndrome (FrX), an X-linked inherited form of mental retardation. Absence of FMRP in Fmr1 null mice imparts some characteristics of the FrX phenotype, but the precise role of FMRP in neuronal...

Species shift their ranges in response to climate change (CC). However, they may not be able track optimal conditions as soon possible, due limited dispersal ability or habitat fragmentation, caused by land use and cover (LULC). This study aimed explore the combined impacts of CC, LULC limitations on future range dynamics Quercus acutissima Carruth., Q. variabilis Blume chenii Nakai, three domi...

Contextualización: El cambio climático y las actividades antrópicas sobre los recursos naturales se constituyen como principales causantes de la pérdida biodiversidad redistribución especies. Vacío conocimiento: Sin embargo, efectos a nivel comunidades ecosistemas, así impactos en cultivos agrícolas escala regional, son poco estudiados. Los modelos distribución especies han convertido, por lo t...

Abstract. Assessments of climate change impacts on runoff regimes are essential to adaptation and mitigation planning. Changing thus changing seasonal patterns water availability strongly influence various economic sectors such as agriculture, energy production, fishery also affect river ecology. In this study, we use new transient hydrological scenarios driven by the most up-to-date local proj...

Increasing heat-stress conditions, rising evaporative demand and shifting rainfall patterns may have multifaceted impacts on Cambodia's agricultural systems, including vegetable production. Concurrently, domestic supply is highly seasonal inadequate to meet the food demand, which consequently poses risks security locally, particularly in rural areas. This study assesses impact of climate change...

A major portion of the United States’ potato (Solanum tuberosum, L.) production occurs in state Washington. Local intensive management practices involving heavy nitrogen and irrigation use can result substantial resource loss due to sandy soils. It is important examine effects water under current climate conditions how these may change future develop best practices. This study simulated respons...

Abstract. Empirical evidence demonstrates that lakes and reservoirs are warming across the globe. Consequently, there is an increased need to project future changes in lake thermal structure resulting biogeochemistry order plan for likely impacts. Previous studies of impacts climate change on have often relied a single model forced with limited scenario-driven projections relatively small numbe...

Plant growth is restricted to times of the year when actual evapotranspiration (AET) greater than zero because AET requires both presence water in soil and temperatures warm enough allow transpiration. Locations where rather temperature limits plant growth, such as semi-arid areas southwestern United States, often have a bimodal growing season, that distinct (growth) peaks occur spring late sum...

• A spatiotemporal approach was used to identify anthropogenic pressure on biomes. The scenarios presented point intensified biodiversity. region with the highest APIB values comprises 30% of territory in all scenarios. Anthropogenic transformations, which have become by land use and cover changes industrialization, contributed increased These disturbances contribute toward fragmentating habita...
