Causes of ice age intensifiion across the Mid

Conflicting sets of hypotheses highlight either the role of ice sheets or atmospheric carbon dioxide (CO2) in causing the increase in duration and severity of ice age cycles ∼1 Mya during the Mid-Pleistocene Transition (MPT). We document early MPT CO2 cycles that were smaller than during recent ice age cycles. Using model simulations, we attribute this to post-MPT increase in glacial-stage

COPD - Symptoms and causes - Mayo Clinic

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs.

Control of blackleg and tuber soft rot of potato …

Calcium is not equally distributed inside plant parts and potato tubers in particular often have a low calcium level (Dunn & Rost, 1945; Collier et al. , 1980). Soils naturally low in Ca can be amended by adding CaSO 4 (gypsum) to increase resistance, not only to blackleg, but also to soft rot of progeny tubers (Bain et al. , 1996).
