Surface characteristics of heated and varnished oriental beech after accelerated weathering
(Slovak Forest Products Research Inst, 2017)
This study was performed to investigate some surface characteristics such as surface hardness, surface roughness, and color changes of heated and varnished Oriental beech (Fagus orientalis Lipsky) after accelerated weathering. ...
Synthesis and antimicrobial activities of hybrid heterocyclic molecules based on 1-(4-fluorophenyl) piperazine skeleton
(Bentham Science Publishers, 2017)
Background: The amine (2) was prepared starting from 1-(4-fluorophenyl) piperazine via two steps, and then converted to the corresponding hydrazide (4). The reaction of hydrazide (4) with carbon disulfide generated the ...
Comparison of reinforced oxygen delignification methods for old corrugated board (OCC) fibres
(Inst Technol Drewna, 2017)
The present work focuses on the effects of sodium percarbonate and hydrogen peroxide as reinforcing agents for the oxygen delignification of old corrugated container paper (OCC). The chemical and crystalline structure, ...
Microwave-assisted synthesis of some hybrid molecules derived from morpholine and investigation of their antimicrobial activities
(Wiley-VCH Verlag GmbH, 2017)
2H-1,2,4-triazol-3(4H)-one compound was obtained starting from 4-(2-fluoro-4-nitrophenyl)morpholine via several steps. Then, these compounds were converted to the corresponding fluoroquinolone hybrids via one pot three ...
Effects of cold stratification and H2SO4 pre-treatments on germination of sea buckthorn (Hippophae Rhamnoides L.) seeds under open field and greenhouse conditions
(Parlar Scientific Publications, 2017)
This study was carried out to determine the effects of some pre-treatments including soaking in concentrate (96%) H2SO4 for 1, 2, 3 and 4 minutes and cold stratification for 10, 20, 30, 40 and 50 days on seed germination ...
A modified ridge m-estimator for linear regression model with multicollinearity and outliers
(Taylor & Francis Inc, 2018)
The ordinary least-square estimators for linear regression analysis with multicollinearity and outliers lead to unfavorable results. In this article, we propose a new robust modified ridge M-estimator (MRME) based on ...
Effects of fire intensity and slope on surface soil erosion following a prescribed fire in old pinus nigra stands
(Parlar Scientific Publications, 2017)
As a practical forest fuel-reduction technique,
prescribed fires have been implemented in many
countries regardless of their potential impact on surface soil erosion process. Greater runoff and surface
soil erosion (rill ...
Gully and streambank erosion and the effectiveness of control measures in a semi-arid watershed
(Parlar Scientific Publications, 2018)
Quantifying the sedimentation contributed by different erosion pathways, including rill, interrill, and gully and streambank soil losses at the watershed scale is crucial to know for adopting the best management practices ...
Abscisic acid cross-talking with hydrogen peroxide and osmolyte compounds may regulate the leaf rolling mechanism under drought
(Springer Heidelberg, 2018)
Leaf rolling observed in some crops such as maize, rice, wheat and sorghum is an indicator of decreased water status. Moderate leaf rolling not tightly or early increases the photosynthesis and grain yield of crop cultivars ...
Preparation and characterization of high-performance wood polymer nanocomposites using multi-walled carbon nanotubes
(Sage Publications, 2017)
Effect of industrial grade multi-walled carbon nanotubes on mechanical, decay, and thermal properties of wood polymer
nanocomposites was investigated. To meet this objective, pine wood flour, polypropylene with and without ...
