Histiocytoid Sweet syndrome (H-SS) is a histological variant of Sweet syndrome (SS) differing from classical neutrophilic SS (N-SS) by a dermal infiltrate mainly composed of lymphocytes and histiocytoid myeloperoxidase-positive cells. We aimed to report a large series of H-SS and compare the frequency and type of hematological malignancies associated to H-SS and N-SS. We included 62 patients wi...
in order to investigate the effect of vermicompost (vc) application on amount of micro elements in soil and plant organs of the medicinal plant of borage (borago officinalis), an experiment was carried out in split plot based on complete randomized block design with three replications in the research farm of the sari university of agricultural science and natural resources. fertilizer treatment...
ABSTRACT The growth of swine production in Brazil has increased the amount and use pig slurry (PS) as soil fertilizer. This product provides nutrients to plants, a continuous application this residue usually increases total organic carbon (SOC) content. objective study was determine SOC content its distribution into humic substance fractions (humic acids, fulvic humin) an Oxisol annually fertil...
The partial substitution of chemical nitrogen fertilizers with organic fertilizer and slow-release could improve pineapple yield use efficiency (NUE) decrease greenhouse gas (GHG) emissions. However, the effect strategies on carbon footprint (CF), (NF) net ecosystem economic benefits (NEEB) from fields in tropics remains largely unclear. Therefore, we conducted a long-term field trial (2017–202...
The expected shortage of global phosphate has enforced the search for alternative resources P fertilizers. Therefore, present study focuses on turnover phosphorus (P) hydrochars and pyrochars derived from sewage sludge (SS) in soils during plant growth. We designed a pot experiment which Lolium perenne L. was allowed to grow Calcic Cambisol amended with SS-derived chars. Hydrothermal carbonizat...
Sixteen multiparous lactating buffaloes after 8 weeks of calving and weighing 500 to 600 kg were used in a complete switch-back design with four groups. Buffaloes in the first group were fed the control ration (R1) consisted of DM basis of 60% concentrate feed mixture (CFM)+20% rice straw (RS)+20% berseem hay (BH), while in the other groups the rations consisted of DM basis of 40% CFM+20% RS+40...
in order to study the effect of different organic fertilizers on quantitative and qualitative characteristics of fenugreek forage, an experiment was conducted based on completely randomized block design with six treatments and three replications at agricultural research station, college of agriculture, ferdowsi university of mashhad, iran, during 2006. the experimental treatments were four orga...
Background In the arid and semi-arid areas of northern China, overexploitation of fertilizers and extensive irrigation with brackish groundwater have led to soil degradation and large areas of farmland have been abandoned. In order to improve the soil quality of abandoned farmland and make reasonable use of brackish groundwater, we conducted field trials in 2013 and 2014. Methods In our study...
Poorly drained claypan soils can increase the importance of tillage and N management for corn (Zea mays L.) production. Field research in 2008, 2009 and 2010 (high rainfall years) near Novelty, MO (40° 1' N, 92° 11' W) sought to determine the effect of polymer-coated urea (PCU) placement [strip-tillage (ST) deep banded and no-till (NT) broadcast] and application timing (fall, early preplant...
One of the most pressing environmental problems worldwide is sewage sludge (SS) management. Every year, wastewater volume increases and thus, amount SS produced as well. The disposal in landfills, practiced many countries, not a sustainable solution. Instead, SS, rich organic matter other nutrients, can be used an alternative soil additive or fertilizer. properties these materials depend on the...
