关于ENVI的大气纠正现有两景某直辖市Landset5 L1T数据（带有元数据）,一般都是对两景图像分别定标,大气纠正,然后在镶嵌和裁剪,但两景数据量都很大（我电脑有点破）,这样做起来很慢.打算简化流程,想先对两景图像定标,然后就镶嵌和裁剪,得到的数据就小一点,接着再做大气纠正,但大气纠正参数中的中心经纬度坐标和成像时间该怎么设置了（毕竟两幅图像镶嵌了呀）?我的这种思路是不是错误的?
镶嵌了以后应该不行,但裁剪后可以,你先裁下来,然后再按照各自的经纬度和时间校正完了,再镶嵌,我觉得是可以的.不太常用这个功能,我的拙见,希望有高手给你解答.

):1401-7.Whole-grain foods do not affect insulin sensitivity or markers of lipid peroxidation and inflammation in healthy, moderately overweight subjects.1, , , , , , , .1Clinical Nutrition and Metabolism, Department of Public Health and Caring Sciences, Uppsala University, Uppsala, Sweden. agneta.andersson@pubcare.uu.seAbstractHigh intakes of whole grain foods are inversely related to the incidence of coronary heart diseases and type 2 diabetes, but the mechanisms remain unclear. Our study aimed to evaluate the effects of a diet rich in whole grains compared with a diet containing the same amount of refined grains on insulin sensitivity and markers of lipid peroxidation and inflammation. In a randomized crossover study, 22 women and 8 men (BMI 28 +/- 2) were given either whole-grain or refined-grain products (3 bread slices, 2 crisp bread slices, 1 portion muesli, and 1 portion pasta) to include in their habitual daily diet for two 6-wk periods. Peripheral insulin sensitivity was determined by euglycemic hyperinsulinemic clamp tests. 8-Iso-prostaglandin F(2alpha) (8-iso PGF(2alpha)), an F(2)-isoprostane, was measured in the urine as a marker of lipid peroxidation, and highly sensitive C-reactive protein and IL-6 were analyzed in plasma as markers of inflammation. Peripheral insulin sensitivity [mg glucose . kg body wt(-1) . min(-1) per unit plasma insulin (mU/L) x 100] did not improve when subjects consumed whole-grain products (6.8 +/- 3.0 at baseline and 6.5 +/- 2.7 after 6 wk) or refined products (6.4 +/- 2.9 and 6.9 +/- 3.2, respectively) and there were no differences between the 2 periods. Whole-grain consumption also did not affect 8-iso-PGF(2alpha) in urine, IL-6 and C-reactive protein in plasma, blood pressure, or serum lipid concentrations. In conclusion, substitution of whole grains (mainly based on milled wheat) for refined-grain products in the habitual daily diet of healthy moderately overweight adults for 6-wk did not affect insulin sensitivity or markers of lipid peroxidation and inflammation.PMID:

AbstractTropical diabetic hand syndrome (TDHS) is an aggressive type of hand sepsis that results in significant morbidity and mortality among patients with diabetes in the tropics. This study set out to establish a protocol for the holistic management of TDHS to improve digit/hand salvage and function at AIC Kijabe Hospital. This prospective study examined the following demographics of patients presenting to the authors institution between October 2009 and September 2010 with TDHS: their sex, age, comorbidities, length of in-hospital stay, surgical and medical treatment, total cost of treatment, and immediate postdischarge outcomes. A total of 10 patients (3 men and 7 women) were presented with TDHS during the study period. Surgical procedures included a thorough debridement of the hand at initial presentation, followed by procedures aimed at preserving length and hand function, with digit or hand amputation when there was no possibility of salvage. Three hands were salvaged, without the ne 2 of these, however, developed severe stiffness with resultant poor function. Fifty percent of the patients developed con 3 of these patients had disabilities of the arm, shoulder, and hand, (DASH) scores of &90 at 6 months after treatment. TDHS appears to be more aggressive in some pat a multidisciplinary approach, with early involvement of the surgical team, and a radical surgical debridement are essential to improved outcomes. Although the goal of medical treatment (ie, glycemic control) is simple and easily achieved, surgical goals (salvage of limb or life, preservation of hand function) are more complex, costly, and difficult to achieve. Educating health care workers, diabetic patients, and their relatives on hand care is an important preventive measure. Diligence in taking antidiabetic medicine, early presentation, and appropriate care of TDHS are required for meaningful improvement in outcomes of patients with diabetes who develop hand sepsis in the tropics.PMID:
