The present analysis provided the quality assessment of 65 Continuous Operating Reference Stations(CORS) situated in and around Mexico using the data of about ten years(January 2010 to January 2020).To accomplish the assessment,we considered 4 quality indexes for performing the quality check,incluing the multipath effect on L1 and L2 bands,signal-to-noise ratio in both bands,cycle slips,and ***,a new reference parameter named regio nal values for Mexico(RVM) was calculated for the stations situated in ***,an exhaustive analysis of the quality indicators in the worst and best cases was *** signal degradation was proved by a long-term time series and cru stal defo rmation analysis in GAMIT/GLOBK *** results showed a stro ng correlation between integrity,cycle slips and daily observations time,and the multipath effect is strong in the case of outdated *** study indicates that the estimated quality indexes and values could be the basis for establishing new CORS in Mexico,and the errors corrections which cannot be mitigated in the postprocessing stage would greatly help utilize the data for different scientific *** results were supported by deformation analysis in part of Baja California Peninsula in Mexico indicating northern and eastern velocity vector of -3.08±0.02 mm/yr,-7.85±0.02 mm/yr and-0.07±0.03 mm/yr,-9.33±0.02 mm/yr respectively at MPR1 and INEG stations.

Determination and Analysis of Hot Spot Areas of Deforestation Using Remote Sensing and Geographic Information System Techniques. Case Study: State Sinaloa, México

Open Journal of Forestry 2016年第4期6卷 295-304页

作者： Sergio Alberto Monjardin Armenta Carlos Eduardo Pacheco Angulo Wenseslao Plata Rocha Gabriela Corrales Barraza rosendo romero andrade Jose Carlos Beltran Gonzalez Faculty of Earth Sciences and Space The Autonomous University of Sinaloa Culiacan México Faculty of Forestry and Environmental Sciences University of the Andes Merida Venezuela

The main objective of this research is to analyze deforestation in State Sinaloa during the period 1990-2014. For this, “deforestationhot-spot areas” were identified, by crossing maps of 1993 and 2011 at a 1:250,000 scale with knowledge from environmental and forest experts from each region. Landsat images from 1990 and 2014 and Terra Amazon System were used to monitor the most critical hot spot area, applying Linear Spectral Mixture Analysis and Image Segmentation Ground Product. In order to generate the map deforestation year zero (1990), every segmented object of ground product was visually assigned to “Forest” and “No-Forest” categories. Therefore, gains and losses were interpreted for the map deforestation year one (2014). Those products were validated with the help of experts on the subject and applying a confusion matrix. Results obtained indicated that the highest forest loss was located in North-Central Sinaloa (hot spot area number two) by establishing the average annual rate of deforestation of 4741.90 ha/year with an average rate of 0.60%, being higher than the national average rate (0.37%). This result affects directlyon calculation of carbonfluxes at nationallevel.

Introduction: In the 1990s, the development of highly active combination antiretroviral therapy in the treatment of AIDS was highlighted. The great benefit generated by the use of this treatment was the prolongation of survival of the people who got this disease, since it is no longer considered fatal, becoming a chronic condition. Objective: To identify the prevalence of the nursing diagnosis Lack of Adherence, its defining characteristics and related factors in people living with AIDS, to investigate the association between them and the prevalence rates. Methods: Cross-sectional study with 113 patients in a hospital in northeastern Brazil. For data analysis, the test of Pearson chi-square and Fisher’s exact test were used, and also calculated the prevalence rates. Results: Lack of Adherence diagnosis was present in 69% of the sample investigated. The defining characteristics and related factors that are statistically associated with that diagnosis were: lack of adherence behavior, missing scheduled appointments, complications related to development, insufficient skills to implement the system and complex treatment system. The first two characteristics had the highest chances for the development of this diagnosis. Conclusion: The study showed that the diagnostic studied was prevalent in these patients and 3 characteristics and 2 factors showed significant association.
