Journal: :Biochar 2022

Abstract There have been many studies on soil quality and crop yield using different biochar application amounts, but few focused the combination of methods amounts in moderately degraded Mollisols. In this study, mixing evenly with plough layer (0–20 cm depth) [homogeneous (HO)] burying above plow pan (under 20 (heterogeneous (HE)) were used to reveal how influenced quality, agronomic characte...

soil quality is a necessary indicator of land management. different indices are applied to evaluate farming systems, soil types and land uses based on soil quality. the slope of retention curve at its inflection point has been defined as soil physical quality index (si) but the relationships between si and penetration resistance (pr), the least limiting water range (llwr), and available water c...

Shifting cultivation (jhum cultivation), a common practice of converting forest land into agricultural by slash and burn is threatening the ecosystem. This study assesses effect shifting cycles on soil quality in North-eastern Himalayan region using minimum properties. To achieve this goal, index (SQI) approach multivariate techniques were used for surface (0-30 cm) subsurface (30-70 layers soi...

Soil quality is related to food security and human survival development. Due the acceleration of urbanization increase in abandoned land, topsoil has deteriorated, thus resulting land degradation recent years. In this study, a minimum data set (MDS) was constructed through principal component analysis (PCA) determine indicator for evaluating Tieling County, northeast China. addition, soil index...

In order to achieve interoperability among learning repositories, implementers require a common communication framework for querying. This paper proposes a set of methods referred to as Simple Query Interface (SQI) as a universal interoperability layer for educational networks. The methods proposed can be used by a source for configuring and submitting queries to a target system and retrieving ...

Desertification is defined as land degradation in arid, semiarid, and dry sub-humid regions, it caused primarily by human activities climate change. The semiarid region of Northeast (NE) Brazil a very large, populous region, thus, hard to monitor the dynamics its desertified areas; therefore, present study aimed develop minimum set biophysical indicators qualify desertification this region. Thi...

abstract soil quality evaluation is an essential issue in soil management for agriculture and natural resource protection. soil quality indices are useful tools for determination and comparison of soils quality. using of principle component analysis in this study we selected 6 important properties as a soil quality minimum data set (mds) among 18 soil properties (tds). then, soil quality of agr...

Journal: :Sleep 2022

Abstract Introduction Idiopathic Hypersomnia (IH) is characterized clinically by excessive daytime sleepiness, prolonged or unrefreshing sleep, and sleep inertia. The ICSD-3 classifies IH as having expected proportions of NREM REM normal latency relatively high efficiency. However, there limited granular data on quality in these patients whether this disease state comprises with a homogenous sp...
