Background: An adequate hydration status is critical to ensure efficiency during mental and physical *** goal was to assess the hydration status of a Spanish group of aeronautical military men and to determine the association of hydration status with body composition and ***: A total of 188 men were evaluated through a validated hydration questionnaire, anthropometric and biochemical parameters, and an anxiety questionnaire. Based on these methods, the criteria of hydration were ***: Of the total sample, 81% met the hydration criteria(urine color = well hydrated, water balance ≥0 ml, and total water intake/weight ≥35 ml/kg), and 19% did not meet the hydration criteria(urine color = not sufficiently hydrated or dehydrated, water balance r intake/weight ration criteria had lower urine pH, negative water balance, and lower water intake. The latter also had higher anxiety status(score=4 vs. 3, P=0.026), weight [(84.7±10.5) kg vs.(80.5±10.2) kg], body mass index [(26.3±3.1) kg/m;vs.(25.2±2.8) kg/m;], body fat [(22.3±5.6)% vs.(18.3±6.5)%], urine specific gravity, and urine color. Using a logistic binary regression model, hydration status was related significantly with the percentage of body fat(P=0.004), but no relation was found with age, comorbidities, or medications. Furthermore, total water intake/weight was positively correlated with percentage of body water(r=0.357, P=0.000) and negatively with body fat(kg)(r=–0.427, P=0.000), percentage of body fat(r=–0.405, P=0.000), and waist/hip ratio(r=–0.223, P=0.002). Based on a linear regression model, total water intake/weight was related significantly with percentage of body fat(P=0.001) and percentage of body water content(P=0.035). No relation was found, however, with waist/hip ratio, age, comorbidities, or ***: These findings all suggest a relationship between hydration status and body composition but

Eyes with glaucoma or any other ocular disease that could alter optical coherence tomography results were excluded. retinal nerve fiber layer(rNFL), Bruch’s membrane opening-minimum rim width(BMO-MrW) and macular thickness(MT) were measured preoperatively, 1 and 6 mo after surgery using spectral-domain optical coherence tomography(SD-OCT). Changes between preoperative and postoperative values were ***: A total of 87 eyes of 46 patients were included in this study. Preoperative rNFL, BMO-MrW and MT in microns(μm) were 100.77±10.39, 330.31±49.99 and 276.30±33.39, respectively. Postoperative rNFL, BMO-MrW and MT were 104.74±11.55, 348.32±54.05 and 279.83±22.65 1 mo after surgery and 102.93±11.17, 343.11±53.4 and 278.90±22.19 6 mo after surgery, respectively;which equals an increase of 3.93%, 5.45% and 1.27%,respectively, 1 mo after surgery, and 2.14%, 3.87% and 0.94% 6 mo after surgery. The differences between the preoperative and the postoperative rNFL and BMO-MrW values were statistically significant(Pregarding MT values, there were not statistically significant differences(P=0.26).CONCLUSION: Our study suggests that FLALS does not have a negative impact on the structural status of the optic nerve head in healthy eyes, assessed by SD-OCT. There is a slight increase in the values of rNFL, BMO-MrW and MT 1 mo and 6 mo after surgery.

Temporal Variation in Composition and Abundance of Phytoplankton Species during 2011 and 2012 in Acapulco Bay,Mexico

Open Journal of Marine Science 2015年第3期5卷 358-367页

Phytoplankton samples were collected in Acapulco Bay during 2011 (January-April and September) and 2012 (April-July, October, and November) with the objective of determining the abundance and species composition. Samples were collected in two stations located in the bay. A total of 82 species were identified: 42 dinoflagellates, 35 diatoms, three cyanobacteria, and two silicoflagellates. Dinoflagellates were more abundant in the dry season, while diatoms dominated during rainy season. At least seven dinoflagellate species were recorded as potentially toxic, which may increase their populations and turn into harmful algal blooms (HABs) if environmental conditions within the bay are modified. In April 2012 a HAB of the non-toxic species Neoceratium balechii was documented.

众筹作为最受欢迎的互联网金融产品之一,受到工业界和学术界的广泛关注。基于现实背景,本文建立了两阶段众筹模型,研究了消费者估值不确定下消费者的策略性选择行为及其对众筹定价策略的影响。结论表明,若消费者参与众筹的额外效用较低,消费者估值不确定会造成“搭便车”现象,导致最优众筹价格不是关于项目所需资金的单增函数。当项目所需资金较低或较高时,发起人应该设置较高的众筹价格,否则应该降低价格以激励更多的消费者参与众筹。通过对比传统销售模式,本文揭示了发起人可以利用消费者估值不确定性及众筹的预售机制增加销量或边际收益以提升利润。进一步,本文证明了退款机制可以有效增加消费者参与众筹的意愿,从而提高众筹的可行域。最后,本文将基本模型拓展到更加一般的情形,研究发现众筹市场大小、项目运作风险和生产能力均对最优定价决策有不可忽视的影响。

Assessing the Crop Growing Period According to the Climate Change Forecasts for Marina Baixa (SE Spain)

引用

Agricultural Sciences 2015年第9期6卷 1079-1088页

作者： Mario Herrera Hassane Moutahir Carlos Alberto gonzález Esteban Chirino juan Bellot Department of Life Sciences University State Amazonia Puyo Ecuador Department of Ecology University of Alicante Alicante Spain Multidisciplinary Institute for Environmental Studies “ramón Margalef” University of Alicante Alicante Spain AdMobilze.Computer Vision Engineer Miami FL USA Faculty of Natural resources Polytechnic Higher School of Chimborazo (ESPOCH) Riobamba Ecuador

The present work aims to assess the likely effects of climate change on the length of growing period (LGP) of crops in Marina Baixa (SE, Spain). LGP can be assessed by a balance between preci- pitation and reference evapotranspiration. Less rainfall and an increased evapotranspiration, forecast by Global Climate Models (GCMs), are considered as a high risk for agriculture. This area is located in a semiarid climate region where water is a very limited resource. It is a typical example of areas where the agricultural sector has to compete for water with the tourism industry. In this context, by using observed and projected precipitation data set (model HadCM3, Scenario A2), calculating reference evapotranspiration (ETo), and applying the frequency analysis of a probability-type method, we estimated the growing period length in the observed period (1961-1990) and three 30-year future periods (2011-40, 2041-70 and 2071-99) in the study area. The results show a drop in annual precipitations (-?30%) and an increased ETo (+18%) towards the end of this century with respect to the observed period (mean annual rainfall: 356 mm;mean ETo: 1476 mm). The results also show a decrease in the number of decades (10 days) when precipitation exceeds half of the ETo, which means shorter growing periods as the 21st century advances. This expected reduction in growing period length towards the end of the present century will imply that many rainfed crops, like olives, almonds and cereals, will require a higher irrigation water supply to maintain suitable growth and performance levels. The results are an early warning to manage water resources in Marina Baixa in a sustainable way.

Advances in the endoscopic management of pancreatic collections

World Journal of Gastrointestinal Endoscopy 2015年第4期7卷 381-388页

Treatment of pancreatic collections has experienced great progress in recent years with the emergence of alternative minimally invasive techniques comparing to the classic surgical treatment. Such techniques have been shown to improve outcomes of morbidity vs surgical treatment. The recent emergence of endoscopic drainage is noteworthy. The advent of endoscopic ultrasonography has been crucial for treatment of these specific lesions. They can be characterized, their relationships with neighboring structures can be evaluated and the drainage guided by this technique has been clearly improved compared with the conventional endoscopic drainage. Computed tomography is the technique of choice to characterize the recently published new classification of pancreatic collections. For this reason, the radiologist's role establishing and classifying in a rigorously manner the collections according to the new nomenclature is essential to making therapeutic decisions. Ideal scenario for comprehensive treatment of these collections would be those centers with endoscopic ultrasound and interventional radiology expertise together with hepatobiliopancreatic surgery. This review describes the different types of pancreatic collections: acute peripancreatic fluid collection, pancreatic pseudocysts, acute necrotic collection and walled-off necrosis; the indications and the contraindications for endoscopic drainage, the drainage technique and their outcomes. The integrated management of pancreatic collections according to their type and evolution time is discussed.
