Since the 1970s, cotton has been a driving force in transformation of agricultural production systems and key element local economies savannah areas West Central Africa (WCA). However, sustainability cotton-based is often debated because their effects on soils negative impacts chemical pest control environment human health. Through drastic reforms, WCA sector overcame crises, showing its resili...

The water conservation function of ecosystems is a research hot spot in the field resources, and it also an important ecological service terrestrial key point eco-hydrology research. With increasing frequency human activities climate change, how to reveal response ecosystem changing environment scientific problem that needs be urgently addressed hydrology To eco-hydrological processes under env...

Weichang’an (WCA) pill, a traditional Chinese patent medicine consisting of ten Chinese medicinal herbs, has been used to treat irritable bowel syndrome and functional dyspepsia for several decades. In this study, twelve bioactive constituents in the methanol extract of WCA were accurately identified since MS/MS fragmentation behavior of the references and the standards by using HPLC-DAD-ESI-MS...

Data is a dominant force during the decision-making process. It can help determine which roads to expand and the optimal location for a grocery store. Data can also be used to influence which schools to open or to shutter and “appropriate” city services to continue or discontinue. Considered fact-based, objective, and impartial, data can trump emotional appeals during the final evaluation of a ...

This paper puts forward the implementation of an intelligent type II fuzzy PID (T2-FPID) controller tweaked with a water cycle algorithm (WCA), subjected to error multiplied time area over integral (ITAE) objective index for regularizing variations in frequency and interline power flow interconnected system during load disturbances. The WCA-based T2-FPID is tested on multi-area (MA) comprising ...

A novel surface-enhanced Raman scattering (SERS)-based probe to capture heavy metal ion (Zn2+) by bovine serum albumin (BSA) using Si-nanowire (SiNW) arrays with silver nanoparticles (AgNPs) was developed. layer AgNPs deposited on the SiNW surface RF magnetron sputtering for enhancement of SERS signals. Using a high-resolution transmission electron microscope (HRTEM), observation reveals that A...

The predictable occurrence of whale sharks, Rhincodon typus, has been well documented in several areas. However, information relating to their migratory patterns, residency times and connectivity across broad spatial scales is limited. In the present study photo-identification data is used to describe whale shark population structure and connectivity among known aggregation sites within the Wes...

Groundnut production is limited in Sub-Saharan Africa and water deficit or "drought," is often considered as the main yield-limiting factor. However, no comprehensive study has assessed the extent and intensity of "drought"-related yield decreases, nor has it explored avenues to enhance productivity. Hence, crop simulation modeling with SSM (Simple Simulation Modeling) was used to address these...

For most tissue engineering applications, surface modification and sterilization of polymers are critical aspects determining the implant success. The first part of this study is thus dedicated to modifying polycaprolactone (PCL) surfaces via plasma treatment using a medium pressure dielectric barrier discharge, while the second part focuses on the sterilization of plasma-modified PCL. Chemical...

Trophic accumulation of mercury (Hg) in aquatic ecosystems is of global concern due to health effects associated with eating fish with elevated Hg levels. The methylated form of Hg bioaccumulates so it is important to understand how inorganic Hg is transformed to methylmercury in the environment. Here, a new site for Hg methylation, the periphyton communities that are prevalent in the Florida E...
