background: heavy menstrual bleeding of endometrial origin (hmb) is a major healthcare problem in premenopausal women and affects several aspects of women’s health and quality of life (qol). the aim of this study was to compare the efficacy of persian golnar (pg) and tranexamic acid (ta) on heavy menstrual bleeding of endometrial origin (hmb) and patients’ qol. methods : a double-blind randomiz...

Aim Precipitation controls the production of semi-arid plants through various mechanisms that operate at a range of time-scales. Short-term variation in precipitation affects vegetation through adjustments in plant physiology and leaf phenology, whereas long-term effects are mediated by plant establishment and mortality, community composition and disturbance regimes. Our goal is to use remote s...

China’s grain production has transformed from absolute shortage to a current structural oversupply. High-intensity production introduced further challenges for the eco-environment, smallholder livelihood, and the man-land interrelationship. Driven by urban-rural transformation, research on food security patterns and grain production has expanded into a new field. To analyze the challenges and r...

The changes in species composition between habitat patches (beta diversity) are likely related to a number of factors, including environmental heterogeneity, connectivity, disturbance and productivity. Here, we used data from aquatic environments in five Brazilian regions over two years and two seasons (rainy and dry seasons or high and low water level periods in floodplain lakes) in each year ...

Cetacean responses to marine anthropogenic activities include changes in acoustic behavior, surface behavior, dive behavior, direction of travel, and behavioral activity states. However, the consequences of these behavioral responses are often difficult to quantify in biological currencies. Previous studies, including our ONR-supported work on the metabolic costs of communicative sound and clic...

Hickory plantations play an important role in improving local farmers’ economic conditions, but extreme drought in July–August 2013 seriously influenced hickory nut production. It is necessary to understand the extent and magnitude of this drought-induced hickory disturbance through mapping its spatial distribution using remote sensing data. This paper proposes a new approach to examine hickory...

Nowadays, production systems seek to integrate production and maintenance activities. An effective maintenance plan can improve maintenance stability and system performance. Machines that stop for repairing operation impose a high cost on the system. On the other hand, there are always some intangible situations during a production process in which repairing activities can be carried out. If th...
