The viability of the use of brackish water in the hydroponic cultivation of vegetables cannot dispense with auxiliary techniques such as water mixing and the use of plant densities. In this sense, the objective of the present work was to analyze the growth and production of sweet pepper, cv. All Big, under hydroponic conditions, under different levels of electrical conductivity of the nutrient solution (1.7, 3.7, 5.7, 7.7, 9.7 and 11.7 dS·m-1) in plants spaced every 0.2 m and 0.3 m. These treatments were distributed in a completely randomized experimental design, analyzed in a 6 × 2 factorial scheme, with five replications. The growth variables were evaluated at 60, 75 and 90 days after sowing and the production variables at the time of harvest;however, the results were submitted to analysis of variance, at a 0.05 probability level. The interaction between the electrical conductivity of the nutrient solution and the density of plants influenced the behavior of the growth and production variables of pepper (All Big). It was verified that the pepper plants had better performance of the biometric variables plant height, stem diameter and number of leaves when cultivated every 30 cm. At the time, in the analysis by plant, the production of pepper fruits was more expressive when spacing of 30 cm was adopted, however, in the tube of six meters, when 20 cm of spacing was used, the number of fruits was on average, 26.38% and 16.40% higher than lower density, in the electrical conductivities 1.7 and 11.7 dS·m-1.

短信服务(SMS)在现代通信技术中得到了广泛的推广。短消息服务组件是现代社会中最快、最常用的电子消息发送方法。垃圾邮件或未经请求的短信已成为组织、网络系统和私人客户端的一个值得注意的问题。通过垃圾短信,垃圾邮件发送者正在影响时间和内存空间,这是计算世界中最重要的资产。垃圾邮件的分类是一个有趣而突出的问题。这里介绍了与垃圾邮件相关的问题以及努力管理垃圾邮件的不同方法。对SMS中的垃圾邮件可用性进行分类是一项具有挑战性的任务,因此,在这方面已经进行了大量的研究,这些研究采用了机器学习技术,如朴素Bayes(NB)、随机森林(RF)和支持向量机(SVM),用于垃圾邮件分类。虽然这些方法表现出了足够的性能,但在垃圾邮件分类方面效率不够。因此,需要进行严格的研究,以找到更准确、更稳健的方法。为了解决这个问题,我们提出了一种新的长期短期记忆(LSTM)方法,它是一种具有包括记忆细胞在内的门控机制的递归神经网络(RNN)的高级结构。此外,本研究还采用了Word2Vec工具,该工具将简化文本转换为向量空间中单词的表示形式。为了评估我们的方法的有效性,SMS数据集已被免费使用。实验结果表明,该方法优于最先进的机器学习方法,如随机林(RF)、SVM、kNN(k最近邻居)、决策树,并提供了97.5%的精度。

Salinity Effects on Development and Productivity of Crambe (<i>Crambe abyssinica</i>) under Greenhouse Conditions

引用

American Journal of Plant Sciences 2015年第7期6卷 839-847页

作者： Ana Carolina F. de Vasconcelos Lúcia Helena G. Chaves Felipe G. Souza hans R. gheyi Josely D. Fernandes Federal University of Campina Grande Campina Grande Brazil State University of Paraíba Lagoa Seca Brazil

Salinity in soil or water in arid and semi arid regions can severely limit crop production, since the high amount of NaCl contributes to specific ion effects of Cl-, Na+ or both, and to antagonistic effects on nutrient elements. Affected by salt stress, most of the cultivated plants do not fully express their growth potential, which lowers their economic value. Crambe (Crambe abyssinica) is an oil plant of the cruciferous family and it is believed that crambe has great potential to figure as raw material for biofuel;however, literature is not abundant about the effects of salinity in crambe production. This work was carried out in order to evaluate the effects on the development and productivity of crambe irrigated with saline waters under greenhouse conditions. Treatments resulted from the combination of two factors: salinity of irrigation water (ECw) in five levels (1.03-control, 2.5, 4.0, 5.5, and 7.0 dS·m-1) and two types of salts (NaCl and NaCl + CaCl2) with three replications, totaling 30 experimental plots. At the end of the experimental period, soil samples from each plot were collected for chemical and salinity of soil saturation extract analyzes. Salt types did not affect plant parameters. However, the salinity levels presented significant effects on the all plant parameters, decreasing their values with the increase of the salt dose. Salinity levels of the solutions used for irrigation in this study affected the growth of plants and grain yield of crambe. Regarding the type of salts, a higher concentration of Na was observed for NaCl solutions at 2.5, 4.0 and 5.5 dS·m-1 salinity levels.

Pulse profile stability of the Crab pulsar

引用

Research in Astronomy and Astrophysics 2011年第10期11卷 1134-1142页

作者： Chetana Jain Biswajit Paul hans raj College University of Delhi Raman Research Institute Sadashivnagar C. V. Raman Avenue

We present an X-ray timing analysis of the Crab pulsar, PSR B0531＋21, using archival RXTE data. We have investigated the stability of the Crab pulse profile, in soft （2-20keV） and hard （30-100 keV） X-ray energies, over the last decade of RXTE operation. The analysis includes measurement of the separation between the two pulse peaks and the intensity and widths of the two peaks. We did not find any significant time dependency in the pulse shape. The two peaks have been stable in phase, intensity and width for the last ten years. The first pulse is relatively stronger at soft X-rays. The first pulse peak is narrower than the second peak in both soft and hard X-ray energies. Both the peaks show a slow rise and a steeper fall. The ratio of the pulsed photons in the two peaks is also constant in time.
