The current status and the domestic research problems of air-borne Synthetic Aperture Ladar (SAL) are introduced and key technologies are analyzed. Based on a principle prototype, the system implementation scheme with a combination of SAR electronics technology and optical technology is given. The future practical system metrics and technological approaches are analyzed. Besides, application direction of Synthetic Aperture Ladar is clarified.

In this paper, in accordance with the existing carbon footprint accounting method, accounting for carbon footprint from white wool top to worsted wool fabric. Results show that the carbon footprint of the high yarn counts wool fabric at this stage is 7.31 kgCO2e/m, the carbon footprint proportion produced by electricity and steam is the largest, more than 85%. Carbon footprint is larger in the stage of top dyeing and spinning. In addition to this, this article also calculatedthe carbon footprint value in various stages; carbon footprint of top dying process is 4.54 kgCO2e/kg wool top, the carbon footprint in the process of spinning is 7.78 kgCO2e/kg yarn, carbon footprint of weaving is 0.08 kg CO2e/m cloth, the carbon footprint of finishing process is 2.53 kgCO2e/m cloth, the carbon footprint of packing stage is 0.27 kgCO2e/m cloth. These results can supply reference for later comparative study, and perfect the carbon footprint of wool products. [ABSTRACT FROM AUTHOR]

The influences degree of decating temperature, decating pressure, decating time, wrapped tension, pressure roller pressure and way through steam on product quality of BISIO decating machine were analyzed and discussed. The results showed that the influences of decating time, wrapped tension, pressure roller pressure and looming counts on product quality and style were significant. In the actual production, we should reasonably select operating decating parameters according to product quality and style. By studying the process decating of BISIO decating machine, the problems of touch panel hard, inside-out color difference and side to side color difference of high temperature and high pressure decating process have solved, and developed a series of decating process parameters suitable for different luster and styles of worsted fabric. The article has provided guidelines for quality percontrol for worsted fabric. [ABSTRACT FROM AUTHOR]

Objective: To retrospectively investigate the prevalence and distribution of chronic kidney disease (CKD) in hospitalized Chinese adult patients., Methods: The medical histories of 13,383 adult patients hospitalized in Zhongda Hospital from September 2004 to August 2005, 6215 males and 7168 female, aged (51 +/- 19) (18 - 103), were reviewed. The blood pressure, serum creatinine, proteinuria were investigated. CKD was defined and classified according to the NKF/DOQI guideline. Glomerular filtration rate (GFR) was estimated by using the simplified modification of diet in renal disease study (MDRD) equation. eGFR = 186.3 x serum creatinine(-1.154) x age(-0.203) x (0.742 for women) ml.min(-1).(1.7 3 m2)(-1)., Results: The prevalence rate of CKD was 14.82% in this group, and the prevalence rates of CKD of stage 1 to 5 were 3.33%, 2.49%, 7.07%, 1.08%, and 0.86% respectively. 53.07% of the CKD patients were elderly patients (age > 65) with a CKD prevalence rate of 29.47%, significantly higher than that of the middle-aged and young patients (9.49%, P < 0.01). The eGFR levels of 9.01% of the hospitalized patients were below 60 ml.min(-1).(1.73 m2)(-1). The prevalence rate of proteinuria was 8.87%. 39.06% of the patients at stages 1 - 3 failed to be diagnosed as with CKD during their hospitalization. The most common causes of CKD were hypertension (29.49%), diabetes (11.64%), and primary glomerulonephritis (4.39%). Hypertension, diabetes and being elderly were main risk factors for CKD., Conclusion: CKD is a very common disease among the hospitalized patients in China. With the increasing number of aging populations, elderly people will be the highest risk group for CKD. More strategies have to be made for its early detection and prevention.
