Driven by global population and standard of living increases, humanity co-opts a growing share of the planet’s natural resources resulting in many well-known environmental trade-offs. In this study, we explored the impact of agriculture on a resource fundamental to life on Earth: terrestrial vegetation growth (net primary production; NPP). We demonstrate that agricultural conversion has reduced...

The concept of electrodiffusion based on the Nernst-Planck equations for ionic fluxes coupled with the Poisson equation expressing relation between gradient of the electric field and the charge density is widely used in many areas of natural sciences and engineering. In contrast to the steady-state solutions of the Nernst-Planck-Poisson (abbreviated as NPP or PNP) equations, little is known abo...

[1] We used a new 17-year, high spatial resolution satellite record and a carbon cycle model to explore how changing net primary productivity (NPP) contributed to a proposed carbon (C) sink in North America. We found a small but significant increase in NPP, 0.03 Pg C yr 2 or 8% over 17 years, that could explain a substantial fraction of the C sink. The largest increases occurred in the central ...

This paper is the continuation of the research devoted to enhancing the adequacy of reliability model of Nuclear Power Plant (NPP) Instrumentation and Control (I&C) Systems considering software reliability. The reliability model of NPP I&C systems is a basement from which the availability, safety, risk, and other important characteristics of the system could be assessed. The availability functi...

زمینه و هدف: NPP (پروتئین جدید افزاینده فشار خون) یک آنزیم پلاسمایی انسانی و از نظر ساختمانی وابسته به b-FXIIa است که به طور شدیدی فشار خون سیستولیک (SBP)، فشارخون دیاستولیک (DBP) و ضربان قلب (HR) را در موش های صحرایی افزایش می دهد. این پاسخ ها در موش های نفرکتومی شده (2NX) شدیدا تقویت می شود. همزمان با آن، افزایش در رهایی کاتکولامین ها از غدد آدرنال نیز دیده می شود. هدف از این مطالعه بررسی مکا...

Neuropathic pain (NPP) is intolerable, persistent, and specific type of long-term pain. It is considered to be a direct consequence of pathological changes affecting the somatosensory system and can be debilitating for affected patients. Despite recent progress and growing interest in understanding the pathogenesis of the disease, NPP still presents a major diagnostic and therapeutic challenge....

Neuropathic pain (NPP) is the main culprit among chronic pains affecting the normal life of patients. Procaine is a frequently-used local anesthesia with multiple efficacies in various diseases. However, its role in modulating NPP has not been reported yet. This study aims at uncovering the role of procaine in NPP. Rats were pretreated with procaine by intrathecal injection. Then NPP rat model ...

Natural and anthropogenic hazards are frequently responsible for disaster events, leading to damaged physical infrastructure, which can result in loss of electrical power for affected locations. Remotely-sensed, nighttime satellite imagery from the Suomi National Polar-orbiting Partnership (Suomi-NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) can monitor power outag...

Five experiments (Exp.) were conducted to determine the effects of phytase on growth performance and intestinal transit time in chicks fed nutritionally adequate diets and diets deficient in Ca and nonphytate P (nPP). In Exp. 1 and 2, chicks were fed a nutritionally adequate diet from 0 to 6 d or from 0 to 4 d posthatching; assay periods were 8 or 10 d; average initial BW were 98 or 79 g; and a...

In December 2014, a group of Australian financial institutions announced that funding had been secured for the next phase of the New Payments Platform (NPP), which will provide the capability for Australian consumers and businesses to make and receive payments in near to real time. The NPP is one example of a fast retail payment system, a number of which have been implemented in other countries...
