Non-Gaussian bias: insights from discrete density peaks

open access: yes, 2013
Corrections induced by primordial non-Gaussianity to the linear halo bias can be computed from a peak-background split or the widespread local bias model.

Simple models and concepts as tools for the study of sustained soil productivity in long-term experiments. II. Crop nutrient equivalents, balanced supplies of available nutrients, and NPK triangles [PDF]

open access: yes, 2011
Two NPK factorial trials, one in Vietnam and one in The Netherlands were (re-)analyzed to find causes of success or failure with regard to sustained soil productivity, using the concept of crop nutrient equivalents (CNE).

Chitosan-based NPK nanostructure for reducing synthetic NPK fertilizers and improving rice productivity and nutritional indices

open access: yesFrontiers in Sustainable Food Systems
Researchers have repeatedly emphasized how urgently we have to decrease the massive nitrogen fertilizer consumption to support agricultural productivity and maintain a sustainable ecosystem. Using chitosan (CS) as a carrier for slow release is considered

Penggunaan Pupuk Hayati dan Pupuk Npk untuk Menekan Penyakit Layu dan Meningkatkan Pertumbuhan dan Hasil Tanaman Kacang Panjang (Vigna Sinencis L.) [PDF]

open access: yes, 2017
The use of either liquid or carrier-based biofertilizers reduced the application of excessive inorganic fertilizers. The purpose of this research was to verified the effect of biofertilizer application of Bokelas Plus (BP) and NPK inorganic fertilizer on

Tunnel magnetoresistance in magnetic tunnel junctions with embedded nanoparticles

open access: yes, 2015
In this paper, we attempt the theoretical modeling of the magnetic tunnel junctions with embedded magnetic and nonmagnetic nanoparticles (NPs). A few abnormal tunnel magnetoresistance (TMR) effects, observed in related experiments, can be easily ...

Effects of different types of fertilizers on plankton productivity in earthen ponds [PDF]

open access: yes, 2003
Three fertilizer types (NPK, Super-phosphate and cow dung) were applied at two levels (Low, 0.3 kg/25m super(2)/2weeks and High, 0.7kg/25 m super(2)/2weeks) to 12 ponds with two ponds serving as control.

Heterogeneity in Short Gamma-ray Bursts

open access: yes, 2011
We analyze the Swift/BAT sample of short gamma-ray bursts, using an objective Bayesian Block procedure to extract temporal descriptors of the bursts' initial pulse complexes (IPCs). The sample comprises 12 and 41 bursts with and without extended emission

Biochar, poultry manure and NPK fertilizer: sole and combine application effects on soil properties and ginger (Zingiber officinale Roscoe) performance in a tropical Alfisol

open access: yesOpen Agriculture, 2020
Biochar has a low chemical composition and is recalcitrant to degradation. For good soil fertility and nutrient use efficiency of crops it becomes imperative that addition of a fast releasing nutrient source to biochar be sought.

Crop growth effects of processed raw materials applied as fertilisers or growth stimulators – a summary of partial EU project results [PDF]

open access: yes, 2006
In an EU CRAFT project (COOP-CT-2004-508458) running from March 2004 to March 2006, an international consortium of producers of environmen-tally benign crop inputs (BFPs: Biological Food for Plants), RTD performers and end users, evaluated the production

Neutron Stars with Bose-Einstein Condensation of Antikaons as MIT Bags

open access: yes, 2010
We investigate the properties of an antikaon in medium, regarding itas a MIT bag. We first construct the MIT bag model for a kaon with$\sigma^*$ and $\phi$ in order to describe the interaction of$s$-quarks in hyperonic matter in the framework of the ...
