Assessment of high speed internet for remote sensing data acquisition and exchange in Colombia and Latin America

New remote sensing platforms and data programs have dramatically increased the availability of satellite image data for analysis of climate, agriculture, environment and society. Particularly important new sensor systems include the USA’s MODIS system, Brazil and China’s CBER platform, and India’s IRS satellite. These and other systems have created considerable benefits to the international community of remote sensing analysts. Today, we have more data with greater options regarding spatial, radiometric and temporal resolution. While having these greater options is a positive development, substantial problems remain in acquiring and managing large data volumes. Data providers and consumers must support significant costs in copying remote sensing data to tapes and disks. Internet transfer of satellite imagery is only possible on broadband networks. Even then, download times can be considerable. Downloads may be interrupted if the Internet connections are unstable. How can we improve the acquisition of large volumes of remote sensing data for environmental analysis? What alternatives are available to remote sensing researchers to acquire near-real time satellite imagery for research use? This paper assesses the potential of high-speed Internet as a medium for transferring large satellite imagery data sets between the United States and Colombia, between Colombia and other Latin American countries and within Colombia. Academic and research networks have led developments in high-speed Internet. Many countries throughout the world are installing the infrastructure needed to develop these networks. In the United States this system is referred to as Internet 2. Latin American countries are developing a system called RedCLARA (Cooperación Latinoamerican

The analysis of X-ray powder diffraction data taken at room temperature reveals that all samples belong to the cubic space group (Cl5b-type structure) with lattice parameters, a, ranging from 7.08 < a < 7.23 angstrom. Interestingly, the analysis of both T-dependence magnetic susceptibility and MvsH loops indicates a gradual transition from antiferromagnetic to ferromagnetic ground states as a function of the Ni-doping. The transition temperatures are confirmed via specific heat measurements. Finally, electron spin resonance data taken in the temperature range of 100 <= T <= 300 K show a single Dysonian line shape, which is characteristic of a metallic environment. A nearly T-independent g-value was observed and the value was concentration independent. Besides, the doped samples show an increase of the residual linewidth, which can be linked with the chemical disorder introduced by the Ni-doping. Our results are discussed considering the bottleneck and multiple band effects on the Gd3+ spin dynamics in this series and their implication in the magnetic frustration observed in these materials.125616FAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULOFUNDAÇÃO DE APOIO À PESQUISA E A INOVAÇÃO TECNOLÓGICA DO ESTADO DE SERGIPECNPQ - CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOCAPES - COORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL E NÍVEL SUPERIORFAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULOFUNDAÇÃO DE APOIO À PESQUISA E A INOVAÇÃO TECNOLÓGICA DO ESTADO DE SERGIPECNPQ - CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOCAPES - COORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL E NÍVEL SUPERIOR2012/04870-72018/11364-72017/10581-1Sem informação304496/2017-0442230/2014-1455608/2014-8455970/2014-900

Avaliação nutricional do capim-elefante fertilizado com composto orgânico oriundo de resíduos da produção e abate de caprinos e ovinos?.

Resumo: Objetivou-se avaliar a composição química do capim-elefante adubado com crescentes doses de composto orgânico produzido a partir de resíduos da produção e abate de pequenos ruminantes. O delineamento foi em blocos casualizados com 6 tratamentos e 4 blocos, totalizando 24 parcelas, sendo aplicadas as seguintes doses (t ha-1): zero; 13,3; 26,6; 39,9; 53,2 e 79,8. Para a diagnose do estado nutricional do capim-elefante, coletou-se 7 amostras simples por parcela, em zigue-zague, de maneira aleatória. A região avaliada foi a primeira folha recém-expandida, sendo as amostras simples as plantas de uma mesma touceira, ao sexagésimo dia após o corte de uniformização. Avaliou-se a análise de macro e micronutrientes do capim-elefante. Houve efeito significativo para os macronutrientes primários nitrogênio, fósforo e potássio (NPK) e o micronutriente zinco. Conclui-se que a aplicação, na capineira, do composto orgânico proveniente de resíduos da produção e abate de pequenos ruminantes proporciona incremento nos teores foliares de N, P, K e Zn. [Evaluation of elephant grass fertilized with compound organic derived of production and slaugher of sheeps and goats]. Abstract: This study aimed to evaluate the nutritional status of elephant grass under doses of organic compound from production residue and slaughter of small ruminants after composting process. The experimental design was randomized blocks with 6 treatments and 4 blocks, total of 24 plots. The doses (t ha-1) applied were: zero; 13.3; 26.6; 39.9; 53.2 and 79.8. In order to diagnose the nutritional status of elephant grass we collected 40 single samples in random way in each plot. The chosen part was the first newly expanded leaf, and the single samples were plants of the same clump on the sixtieth day after the uniformity cut. We evaluated the chemical analysis of macronutrients and micronutrients in elephant grass. The results showed that there were significant effects on primary macronutrients nitrogen, phosphorus and potassium (NPK) and zinc micronutrient. The results show that the application of organic compound from production residue and slaughter of small ruminants provided an increase in the leaf levels of N, P, K and Zn

Annexin A6 Is Critical to Maintain Glucose Homeostasis and Survival During Liver Regeneration in Mice

Background and Aims: Liver regeneration requires the organized and sequential activation of events that lead to restoration of hepatic mass. During this process, other vital liver functions need to be preserved, such as maintenance of blood glucose homeostasis, balancing the degradation of hepatic glycogen stores, and gluconeogenesis (GNG). Under metabolic stress, alanine is the main hepatic gluconeogenic substrate, and its availability is the rate‐limiting step in this pathway. Na+‐coupled neutral amino acid transporters (SNATs) 2 and 4 are believed to facilitate hepatic alanine uptake. In previous studies, we demonstrated that a member of the Ca2+‐dependent phospholipid binding annexins, Annexin A6 (AnxA6), regulates membrane trafficking along endo‐ and exocytic pathways. Yet, although AnxA6 is abundantly expressed in the liver, its function in hepatic physiology remains unknown. In this study, we investigated the potential contribution of AnxA6 in liver regeneration. Approach and Results: Utilizing AnxA6 knockout mice (AnxA6−/−), we challenged liver function after partial hepatectomy (PHx), inducing acute proliferative and metabolic stress. Biochemical and immunofluorescent approaches were used to dissect AnxA6−/− mice liver proliferation and energetic metabolism. Most strikingly, AnxA6−/− mice exhibited low survival after PHx. This was associated with an irreversible and progressive drop of blood glucose levels. Whereas exogenous glucose administration or restoration of hepatic AnxA6 expression rescued AnxA6−/− mice survival after PHx, the sustained hypoglycemia in partially hepatectomized AnxA6−/− mice was the consequence of an impaired alanine‐dependent GNG in AnxA6−/− hepatocytes. Mechanistically, cytoplasmic SNAT4 failed to recycle to the sinusoidal plasma membrane of AnxA6−/− hepatocytes 48 hours after PHx, impairing alanine uptake and, consequently, glucose production. Conclusions: We conclude that the lack of AnxA6 compromises alanine‐dependent GNG and liver regeneration in mice
