Reduced Sensitivity RDX (RS‐RDX) in Pressed Formulations: Respective Effects of Intra‐Granular Pores,Extra‐Granular Pores and Pore Sizes

Reduced sensitivity RDX (RS‐RDX) particles are now available from several manufacturers. But a clear understanding of this reduced sensitivity behavior is not yet available. RS‐RDX particles are usually employed in cast formulations to reduce their shock sensitivity. The use of RS‐RDX in pressed formulations is more recent and does not always give reduced sensitivity formulations.     

Topical delivery of fluconazole: in vitro skin penetration and permeation using emulsions as dosage forms

We investigated in vitro skin penetration and permeation of fluconazole from emulsions containing different penetration enhancers. Fluconazole permeation was high (15-65% of the applied dose) across hairless mouse skin and low (8-9%) across pig ear skin. Permeation across mice skin from a formulation containing propyleneglycol and isopropyl myristate was significantly higher than that observed with the paraffin oil and propyleneglycol or Transcutol® emulsions. With pig skin, the paraffin oil or isopropyl myristate and propyleneglycol emulsions showed similar skin permeation and penetration. However, these emulsions provided epidermal concentrations higher than the minimal inhibitory concentrations for most dermatophytes.

改善水泥浆堵剂县浮性能的研究

水泥浆堵剂HS－2在特高含水期已广泛用于高渗透带和大孔道的封堵治理,以调整或改善注入的吸水剖面,HS－2的主要成分为普通水泥,含有相应的一些添加剂,在注入过程中水泥颗粒受重力影响,易发生分层沉降,使水泥泵入性能变坏,不能有效地将水泥颗粒带入地层设计深度,在预定的位置水化固结,本文报道解决普通水泥浆悬浮性和凝固性的途径及得到的这两项性能良好的水泥浆堵剂,室内评价结果表明它的封堵效果良好,可用于有高渗透带和大孔道的注水井深部调剖。
