AbstractUntil now, an assumption of surface-parallel glacier flow has been used to express the vertical velocity component in terms of the horizontal velocity vector, permitting all three velocity components to be determined from synthetic aperture radar interferometry. We discuss this assumption, which neglects the influence of the local mass balance and a possible contribution to the vertical velocity arising if the glacier is not in steady state. We find that the mass-balance contribution to the vertical surface velocity is not always negligible as compared to the surface-slope contribution. Moreover, the vertical velocity contribution arising if the ice sheet is not in steady state can be significant. We apply the principle of mass conservation to derive an equation relating the vertical surface velocity to the horizontal velocity vector. This equation, valid for both steady-state and non-steady-state conditions, depends on the ice-thickness distribution. Replacing the surface-parallel-flow assumption with a correct relationship between the surface velocity components requires knowledge of additional quantities such as surface mass balance or ice thickness.

Background: The purpose of this study was to analyze the menu engineering data: preferences, acceptances, and popularity indexes of local food package menus with low to moderate glycemic index and how these variables affect the glycemic response of subjects with type 2 diabetes mellitus (T2DM). Methods: This study was a one group pre and post-test experimental study with 21 T2DM participants. A total of 1,764 menu engineering data were obtained during the two-week study period. Fifteen food service survey questions were distributed and anthropometric and glycemic responses were measured. Results: The popularity indexes of the main and snack package menus were significantly different (p=0,000). There was a significant decrease (p<0.05) in Δ RBG levels by 59.6±115.8 mg/ dL (26.7%) and Δ % albumin glycated by 1.5±1.0 (6.1%) (p = 0.000) on 38% subjects with good glycemic control who consumed less food outside the study (12.5%). Price, type of food, type of foodstuff, nutrient content, portion size, food appearance, food texture, GI values, food menu name, and menu conformity to the environment were important considerations in the menu preference and popularity. Conclusion: This study showed that the local food package menu can control the glycemic response of T2DM participants while having a high popularity index. This finding provides an opportunity for the foodservice industry to operate sustainably by considering the factors desired by consumers with T2DM in controlling their long-term glycemic response.
