Values for particle-scale properties of biomass briquettes made from agroforestry residues

particuology 2014年第1期12卷 100-106页

The production of biomass pellets and briquettes from agroforestry residues has increased rapidly in recent years. The design of machines, equipment and the infrastructure necessary for the handling, trans port and storage of these products has been an engineering challenge since, when moving, biomass does not usually flow as easily as other granular materials. The discrete element method （DEM） provides a means of studying the handling and silo discharge behaviour of granular solids as well as the distribution of the pressures exerted by such materials in silos. However, the development of such models requires certain properties of the particles in question to be known. The present work experimentally determines the true density, Young＇s modulus of elasticity （axial and radial）, the particleparticle restitution coeffi cient and the particlewall friction coefficientall variables that must be known in the construction of DEM modelsfor briquettes made from maize stalk, maize stalk plus pine wood chips, rice husk, vine shoots, raoe straw, cereal straw and sawdust olus cereal straw.

A logarithmic rapid desensitization protocol: initial experience in carboplatin hypersensitivity reactions

引用

Journal of Cancer Metastasis and Treatment 2019年第8期4卷 21-28页

Aim: Hypersensitivity reactions to carboplatin are not an infrequent adverse event in ovarian cancer patients. However, reintroduction of platinum-containing schedules is the standard of care in platinum-sensitive recurrent ovarian cancer. Rapid desensitization is a procedure for gradual reintroduction of drug. It allows a safe administration of medications that are beneficial for the management of patients after certain types of hypersensitivity reactions. It is indicated in cases in which there are no reasonable therapeutic alternatives. Methods: We performed a descriptive retrospective study of high-grade ovarian cancer patients with known carboplatin hypersensitivity reactions that were treated with a 13-steps rapid desensitization protocol with 3 different solutions and infusion rates. The procedure followed a mathematic model (gradual increases with a relationship between doses following a geometric series) which is called logarithmic rapid desensitization protocol (LRDp). The aim was to describe the safety of the LRDp in terms of number and severity of infusion reactions and the effectiveness in the rate of cycles completely administered. Results: Four different patients diagnosed with recurrent platinum-sensitive ovarian cancer with a previous infusion reaction were included. LRDp was administered in 19 different cycles. LRDp was administered safety in all 19 cycles, only 2 patients had a mild cutaneous reaction in 4 different cycles during LRDp (21.05%). The foreseen dose of carboplatin was fully administered in all ***: LRDp with carboplatin is a feasible and safe protocol in patients with previous infusion reaction to carboplatin. The protocol might allow a safe administration of drugs, that are beneficial for the management of patients, after certain types of hypersensitivity reactions, and it is indicated in cases in which there are no reasonable therapeutic alternatives.
