The depletion of shallow groundwater has seriously affected the sustainable development water resources in North China Plain (NCP). Based on 556 well monitoring observations over a period 13 years, we quantitatively evaluated sustainability NCP via various indices (e.g., reliability, resilience, vulnerability, and indices), further discussed contribution different drivers (including climatic no...
Bovine viral diarrhoea virus (BVDV), a member of the Pestivirus genus, is one of the most important pathogens of dairy cattle; it can cause several clinical syndromes, ranging from subclinical to severe disease. The objectives of the current studies were to assess the effects of two biotypes of BVDV on sperm attachment to the zona pellucida (ZP) of oocytes and on fertilization rate in bovine in...
OBJECTIVE Prior studies examining coronary atherosclerosis in the young have been limited by retrospective analyses in small cohorts. We examined the relationship between cardiovascular risk factors (RFs) and prevalence and severity of coronary atherosclerosis in a large, prospective, multinational registry of consecutive young individuals undergoing coronary computerized tomographic angiograph...
Net community production (NCP) and nutrient de"cits (Def(X)) were calculated using decreases in dissolved CO 2 and nutrient concentrations due to biological removal in the upper 200m of the water column during four cruises in the Ross Sea, Antarctica along 76330@S in 1996 and 1997. A comparison to excess dissolved and particulate organic carbon showed close agreement between surplus total organ...
BACKGROUND Apoprotein B-containing lipoproteins are atherogenic, but atheroprotective functions of apoprotein A-containing high-density lipoprotein (HDL) particles are poorly understood. The association between lipoproteins and plaque components by coronary computed tomography angiography (CTA) and intravascular ultrasound with radiofrequency backscatter (IVUS/VH) has not been evaluated. METH...
In the west of province Córdoba (Argentina) deep socio-productive changes are occurring as a consequence expansion agricultural frontier. Drawing upon participatory, multiactor and interdisciplinary methodology, paper analyzes a) how different types producers perceive value ecosystems Nature’s Contributions to people (NCP) they produce; b) strategies developed by appropriate NCP, c) role that t...
Nature's contributions to people (NCP) rarely originate from nature alone. Often, only by joining natural capital with forms of anthropogenic capital, NCP emerge benefitting people. Understanding how are co-produced and capitals is needed inform decision-making on sustainable land-use practices. Through a systematic review the literature, we compile existing empirical evidence co-production thi...
We propose a class of parametric smooth functions that approximate the fundamental plus function, (x) + =maxf0; xg, by twice integrating a probability density function. This leads to classes of smooth parametric nonlinear equation approximations of nonlinear and mixed complementarity problems (NCPs and MCPs). For any solvable NCP or MCP, existence of an arbitrarily accurate solution to the smoo...
Photonic crystals have been studied extensively for their potential to control and manipulate light, similar to the way electrons are controlled in a semiconductor, opening the door to high-speed, low-power, all-optical devices. A common method for fabricating 3D photonic crystals is the infiltration and subsequent inversion of synthetic opal templates to create inverse opals consisting of air ...
The release in 2007 of the National Quality Forum (NQF) preferred practices is a significant advance in the field of palliative care. These NQF preferred practices build on the clinical practice guidelines for palliative care developed by the National Consensus Project (NCP). The NQF is dedicated to improving the quality of American health care, and their focus on palliative care recognizes its...
