Rosa centifolia is grown for its flowers which are used for essential oil extraction. It is vegetatively propagated through its cuttings which are difficult to root. This study was designed to increase the rooting percentage of cuttings by applying plant growth regulators (PGRs) with different levels. In total 31 treatments with different concentrations (450 ppm, 700 ppm and 950 ppm) of indole butyric acid (IBA), indole acetic acid (IAA), naphthalene acetic acid (NAA) alone, in combination and with same concentrations of 6-benzylamino purine (BAP) were used. Healthy similar sized cutting of R. centifolia was treated in solution of PGRs by quick dip method and planted in polythene bags. The data for shoot length, shoot dry weight, number of roots, root length and root dry weight were recorded. All three levels (450 ppm, 700 ppm and 950 ppm) of IBA alone produced maximum results in case of all parameters as compared to all other treatments. Among three levels of IBA, 450 ppm concentration produced maximum shoot length (10.67 cm), shoot dry weight (3.02 g), number of roots (14.00), root length (11.90 cm) and root dry weight (0.50 g). Lower concentrations of plant growth regulators produced better results as compared to higher concentrations.

A CO2 solid sorbent based on polyethyleneimine 10k (PEI-10k) impregnated into mesoporous silica (MPS) foam was synthesized and utilized to capture CO2 at temperatures ranged from 65°C to 95°C. The calculated nitrogen and carbon contents in the bulk of the PEI-10k/MPS sorbent were similar to the XPS results measured on the surface of the foam, suggesting that the PEI was homo-geneously distributed throughout the MPS support. After CO2 adsorptionthe N 1s peak was broadened and could be resolved into two components: a high binding energy component (~401 eV) and a lower binding energy one (396 eV), respectively. The former nitrogen states are consistent with a protonated amine, presumably, due to carbamate formation. The lower binding energy component (~396 eV) could possibly be due to strongly chemisorbed CO2. The maximum sorption capacity was about 4 mmole CO2/g sorbent at 85°C and 1 bar. This capacity was doubled by raising the CO2 pressure to 24.95 bars. The adsorption results can be described by a Langmuir adsorption isotherm.

针对印刷体维吾尔文字识别中字体单一、识别数据规模小、识别领域不区分以及哈萨克和柯尔克孜文字识别研究缺乏等问题,提出了基于卷积神经网络(CNN)的多字体印刷体维吾尔、哈萨克和柯尔克孜(以下简称维-哈-柯)文关键词识别方法。首先,针对维-哈-柯文关键词图像语料库缺乏的问题,基于图像合成技术构建包括32种字体的维-哈-柯文关键词图像数据集。然后,使用数据扩充技术对数据集的图像进行不同程度的加噪、旋转和失真操作,来进一步体现数据集的自然场景特征。最后,使用多层CNN网络在该数据集上训练图像识别模型,均得到了96.5%以上的识别准确率,并在包括3种常用字体的实际印刷体图像识别任务中得到了96%左右的准确率,该方法减少了预处理过程,并胜过了以往机器学习框架下的其他识别方法。实验结果表明,在CNN网络框架下基于合成图像和数据扩充技术的识别方法能够较好地实现多字体印刷体维-哈-柯文图像识别任务。

Many attempts are made to obtain the composition of vacuum gas oil（VGO） but the molecular composition of hydrogenated vacuum gas oil（HVGO） has not been studied in detailHVGO is used as a feed in fluid catalytic cracking（FCC） to produce more environmentally friendly gasolineThis paper reports the presence of linear alkyl cyclohexanes（LACHs） in HVGOSome LACHs were found in HVGO distillates of boiling point range of 370°C-550°CComplete molecular composition was analyzed using gas chromatography mass spectrometry（GC-MS）HVGO contains LACHs from C7 to C32 and n-paraffins from C5 to C38Open chain hydrocarbons are the major constituents of all the six samples of HVGOAromatic compounds were also identified but their concentration was very lowSulfur contents were about 0.26% by weight percentage（wt）.The present paper focuses on development of method for qualitative and quantitative determination of LACHs in HVGO samples using GC-MS analysis method.

We report novel gold nanoparticles by green method for different fruit extracts have gaining greater attention due to its versatile properties in different applications. In this article, GNPs synthesis is demonstrated successfully using fresh fruit extract of punica granatum and fragaria. The optical properties, morphology and elemental analysis of samples was done by using) different characterization techniques like SEM EDX and UV-Visible spectroscopy Biocompatibility of GNPs was determined by ALT, AST, ALP, Urea, Creatinine tests and also to investigate the effects of prepared GNPs on the kidney and liver functions. The GNPs prepared by fruit extract of punica granatum have more effects on the rabbits than GNPs prepared from fragaria but this effect normalizes after three days which shows its biocompatibility. To explore the photocatalytic activity of the GNPs the photocatalytic degradation of MB dye is also investigated. The results revealed that GNPs prepared through green synthesis route are found to be efficient enhancement in the degradation of MB dye in visible region due to large surface area. These particles were more active in catalytic reduction due to their high surface energy and in bio-medical applications as biocompatibility.

Background: Several circumstances and conditions lead to UGIB. The commonest among them peptic ulcer to an approximation of 50% in cases. The second major cause may be esoghageal varices and third is mallory-weis tears. There are also other causes, which may include erosins, tumors and other malformations like arteriovenous. Methods: This was an observational retrospective study of all patients referred to endoscopy. The study exclusion criteria include all patients who had repeat endoscopies within one month of the previous endoscopy whereas all the patients with UGIB were included in this study. Results: We retrieved data of total 150 patients who had experienced upper gastrointestinal endoscopy during the selected time period covered in the study, March 2015 to February 2016. The mean age of the patients was 43.3 ± 13.80. 80 (53.3%) of the patients were male and 70 (46.7%) were females. Exploring more into UGIB causes the majority of patients were with esophageal varices 68 (45.3%) with male to female share was 2:1. The second most cause was esophagitis (n = 22, (14.67%)), the distribution of the cause was similar in male to female. Conclusion: We may conclude from our findings that the most common cause of UGIB is esophageal varices in our population.
