This paper introduces the composite waterproofing and drainage board, to solve issues such as the drainage problem and lack of sand gravel material in low filled embankment of plain area highway. Through the research of its application performance, design method and drainage effect. Studies show that the materials with perfect performance on tensile and compression strength are contribute to construction property of soil which under the board, it also can effective prevent water from seeping through the underground, and expel surplus water, to make sure the long-term stability of subgrade and subsoil. It is one perfect waterproofing and drainage materials used in low embankment highway.

Mineralogy has many applications in the business of waste and waste disposal:•precipitation of minerals and adsorption of elements and compounds to mineral surfaces can serve to immobilize pollutants or concentrate them for recycling•release of elements and compounds can occur by the converse processes of dissolution and desorption•minerals can act as impermeable barriers between pollutants and the environment•minerals can be used as analogues to determine the long-term stability of engineered materials used for the encapsulation of waste.The Applied Mineralogy Group of the Mineralogical Society organized a meeting ‘The mineralogy of waste and waste disposal’ held at the British Geological Survey, Keyworth, Nottingham, on 25th September 2000. The meeting attracted members of both the academic (Earth Science, Chemistry and Material Science departments) and industrial communities. A wide variety of papers was presented dealing with such diverse issues as nuclear waste disposal and the recycling of phosphorus from wastewater. Seven of the papers are collected here.

Bone implants are long term solutions for bone loss. Currently, two issues have been identified as reducing the long term stability of bone implants. The first issue is stiffness mismatch between the implant and the surrounding bony structure. The current materials used for manufacturing bone implants are much stiffer than the surrounding host bone. The second issue concerns bone-implant integration; the fact is that the bone needs an appropriate surface on which to attach and accept or deliver a load. Additive manufacturing techniques using Nitinol may provide the ability to fabricate bone implants with predetermined pore size and stiffness. This work brings the concept of stiffness tailoring to reality, taking advantage of additive manufacturing technique to fabricate engineering porosity to modify the stiffness. Based on the simulation and test results, it is shown that implants can be made with the stiffness in the range of the stiffness of the bone. The same capabilities can be used to affect a rough surface onto which bone is more likely to attach.

Abstract. The concept of emotional intelligence (EI) has attracted growing interest from researchers working in various fields. The present study examined the long-term stability (32 months) of EI-related abilities over the course of a major life transition (the transition from high school to university). During the first week of full-time study, a large group of undergraduates completed the EQ-i:Short; 32 months later a random subset of these students (N = 238), who had started their postsecondary education within 24 months of graduating from high school, completed the measures for a second time. The study found EI scores to be relatively stable over the 32-month time period. EI scores were also found to be significantly higher at Time 2; the overall pattern of change in EI-levels was more than can be attributed to the increased age of the participants.

SummaryIn a collaborative trial of eleven laboratories which was performed mainly within the framework of the European Community Bureau of Reference (BCR), a second reference material for thromboplastin, rabbit, plain, was calibrated against its predecessor RBT/79. This second reference material (coded CRM 149R) has a mean International Sensitivity Index (ISI) of 1.343 with a standard error of the mean of 0.035. The standard error of the ISI was determined by combination of the standard errors of the ISI of RBT/79 and the slope of the calibration line in this trial.The BCR reference material for thromboplastin, human, plain (coded BCT/099) was also included in this trial for assessment of the long-term stability of the relationship with RBT/79. The results indicated that this relationship has not changed over a period of 8 years. The interlaboratory variation of the slope of the relationship between CRM 149R and RBT/79 was significantly lower than the variation of the slope of the relationship between BCT/099 and RBT/79. In addition to the manual technique, a semi-automatic coagulometer according to Schnitger & Gross was used to determine prothrombin times with CRM 149R. The mean ISI of CRM 149R was not affected by replacement of the manual technique by this particular coagulometer.Two lyophilized plasmas were included in this trial. The mean slope of relationship between RBT/79 and CRM 149R based on the two lyophilized plasmas was the same as the corresponding slope based on fresh plasmas. Tlowever, the mean slope of relationship between RBT/79 and BCT/099 based on the two lyophilized plasmas was 4.9% higher than the mean slope based on fresh plasmas. Thus, the use of these lyophilized plasmas induced a small but significant bias in the slope of relationship between these thromboplastins of different species.

The Stability

SummaryThe International Reference Preparation of human brain thromboplastin coded 67/40 has been thought to show evidence of instability. The evidence is discussed and is not thought to be strong; but it is suggested that it would be wise to replace 67/40 with a new preparation of human brain, both for this reason and because 67/40 is in a form (like Thrombotest) in which few workers seem to use human brain. A �plain� preparation would be more appropriate; and a freeze-dried sample of BCT is recommended as the successor preparation. The opportunity should be taken also to replace the corresponding ox and rabbit preparations. In the collaborative study which would be required it would then be desirable to test in parallel the three old and the three new preparations. The relative sensitivities of the old preparations could be compared with those found in earlier studies to obtain further evidence on the stability of 67/40; if stability were confirmed, the new preparations should be calibrated against it, but if not, the new human material should receive a calibration constant of 1.0 and the new ox and rabbit materials calibrated against that.The types of evidence available for monitoring the long-term stability of a thromboplastin are discussed.
