The policies of marine ecological civilization involve multiple policy areas such as marine economy, marine environment, and marine society. This paper sorted out 54 related policies of marine ecological civilization in Shandong Province, constructed a co-word matrix of policy keywords, and used co-word analysis method to conduct quantitative analysis. Through the measurement of policy network centrality, policy theme groups and structural holes, the coordination of policy contents and the centrality of policy points were analyzed. The study has found that among the comprehensive policies for marine ecological civilization construction in Shandong Province, the marine ecological environmental protection policies have more focuses and have formed a relatively complete system, but the relevancy of the policy points of marine science and technology innovation related to marine support policies is not high, and the support for marine environmental protection technology innovation is not strong. These discoveries are also reflected in the subsequent content analysis of marine social support policies, and they also affect the coupling degree between the marine ecological environment and marine ecological society in Shandong Province to a certain extent. 展开更多

Text analysis is a popular technique for finding the most significant information from texts including semantic,emotional,and other hidden features,which became a research hotspot in the last few years.Specially,there are some text analysis tasks with judgment reports,such as analyzing the criminal process and predicting prison terms.Traditional researches on text analysis are generally based on special feature selection and ontology model generation or require legal experts to provide external knowledge.All these methods require a lot of time and labor costs.Therefore,in this paper,we use textual data such as judgment reports creatively to perform prison term prediction without external legal knowledge.We propose a framework that combines value-based rules and a fuzzy text to predict the target prison term.The procedure in our framework includes information extraction,term fuzzification,and document vector regression.We carry out experiments with real-world judgment reports and compare our model’s performance with those of ten traditional classification and regression models and two deep learning models.The results show that our model achieves competitive results compared with other models as evaluated by the RMSE and R-squared metrics.Finally,we implement a prototype system with a user-friendly GUI that can be used to predict prison terms according to the legal text inputted by the user. 展开更多

In recent years, the understanding of human health has progressed considerably, through the study and understanding of the symbiotic role played by the myriad microorganisms that populate the gut and do the digesting, and populate the skin and keep it healthy, and even populate the lining of the lungs and do the same. In plant life, it is the microorganisms in the soil—which “are” the soil’s fertility—which fulfil a similar symbiotic role in a healthy plant’s life, but as yet this is a subject most visible by its absence from all scientific discussion of good farming practice. The science underlying this understanding is summarised in this paper. Understanding this and nurturing the fertility of impoverished soil by “seeding it” with the appropriate mix of microorganisms is transformational for plant health and productivity. Significant results are indicated from early trial examples of doing this in rice, oil palm and tobacco cultivation in Malaysia. 展开更多

This present study compared antioxidant and antimicrobial activities of acetone and water extracts of <i>Theobroma cacao</i> beans against <i>Escherichia coli</i>. Total phenolic content (TPC) in both extracts was estimated by the Folin-Denis reagent. The present study showed that the 70% (v/v) acetone extract had a higher extraction yield and TPC (37% and 109 mg TAE g<sup>-1</sup> dry weight) than the water extract (33% and 76 mg TAE g<sup>-1</sup> dry weight). The antioxidant activities of both extracts were estimated by the DPPH Scavenging Assay. The extract obtained using 70% (v/v) acetone showed higher antioxidant activity (54%) compared to the antioxidant activity obtained using water (34%). Antimicrobial activities of acetone and water extracts from <i>Theobroma cacao</i> were measured against <i>Escherichia coli</i> and were screened by agar well diffusion method and further confirmed with the disc diffusion method. The bacterial growth was measured in Mueller Hinton agar. The extracts inhibited the growth of the <i>Escherichia coli</i> cultured, and the acetone extracts showed antimicrobial capacity comparable or equivalent, as seen in commercial ampicillin. 展开更多

A study was conducted to screen out the low-temperature tolerant Boro rice seedlings from November 2012 to January 2013 for facing the upcoming rice production challenge in Northwest Bangladesh. The experimental time was characterized by a prevailing low environmental temperature of below 15°C. Five rice cultivars (V1: BR-2;V2: BR-16;V3: Pariza;V4: Minicate;V5: BRRI dhan 50) were selected for the study. The leaf proline, chlorophyll content and total carotenoid content were investigated. The V2 (BR-16) seedling synthesized the higher leaf proline (1.228 g&middot;g-1) at a low temperature than those of other tested cultivars. Again, the highest amount of chlorophyll-a (3.957 g&middot;g-1), chlorophyll-b (2.118 g&middot;g-1), chlorophyll-a/b ratio (3.6754 mg&middot;g-1) and total chlorophyll (5.051 g&middot;g-1) was measured in V2 (BR-16). The maximum total carotenoid (1.213 g&middot;g-1) was also observed in V2. In this experiment, the V2 (BR-16) showed comparatively better potentiality to survive at low temperatures (below 15&deg;C) than other varieties. 展开更多

The study examined the effects of nitrogen fertilizer application on yields and nitrogen use efficiencies of <i>Solanum macrocarpon</i> and <i>Solanum scabrum</i> in Iwaro-Oka, Ondo State in southwest Nigeria in 2014 and 2015. The experiment was a 4 × 4 factorial arranged into a randomized complete block design with four rates of urea-N drilled at 0, 40, 80 and 160 kg/ha and replicated four times. Each plot was 3 m × 2 m with space of 1 m between plots. Vegetable seeds were planted by drilling. Fresh shoot and dry matter yields were determined. Nitrogen content and uptake were determined, and nitrogen use efficiency estimated. The result showed that average dry matter weight for <i>S. macrocarpon</i> was 228 kg/ha and <i>S. scabrum</i> was 6116 kg/ha. Average nitrogen uptake was 5.90 kg/h and 158.60 kg/ha for <i>S. macrocarpon</i> and <i>S. scabrum</i>, respectively. Nitrogen use efficiencies were 6.48 kg/ha, 0.15 kg/ha and 0.1 kg/ha for <i>S. macrocarpon</i> and 87.33 kg/ha, 26.14 kg/ha and 24.35 kg/ha for <i>S. scabrum</i> at 40, 80 and 160 kg N/ha, respectively. Negative values were obtained for N-recovery for <i>S. macrocarpon</i> while <i>S. scabrum</i> gave 5.85%, 2.10% and 1.44% at 40, 80 and 160 kg N/ha, respectively. The study concluded that <i>S. scabrum</i> had higher nitrogen use efficiency in the soil than <i>S. macrocarpon</i> and that highest NUE and N recovery were obtained at 40 kg N/ha. 展开更多

Objective: Prostate specific antigen (PSA) does not provide the high reliability and precision that is required for an accurate screening for prostate cancer?(PCa). The aim of our study was to search for a simple, rapid, direct, preferably non-invasive, and highly accurate biomarker and procedure for the screening for PCa. Method: The levels of trace elements (TE) Br, Fe, Rb, Sr,?and Zn were prospectively evaluated in expressed prostatic fluid (EPF). Also?Zn/Br, Zn/Fe, Zn/Rb, Zn/Sr concentration ratios as well as ZnRb and (ZnRb)/Fe concentration combinations were calculated for EPF samples, obtained from 38 apparently healthy males and from 33, 51, and 24 patients with chronic prostatitis, benign prostatic hyperplasia, and PCa, respectively. Measurements were performed using an energy dispersive X-ray fluorescent (EDXRF) microanalysis. Results: It was found that in the EPF of cancerous prostates the levels of Rb, Zn, Zn/Br, Zn/Fe, Zn/Sr, ZnRb, and (ZnRb)/Fe were significantly lower in comparison with those in the EPF of normal, inflamed, and hyperplastic prostates. For example, in comparison hyperplastic?with cancerous prostates p values obtained using Student’s t-test and?Wilcoxon-Mann-Whitney U-test were Conclusions: The levels of TE and their combinations in EPF, obtained by EDXRF, is a fast, reliable, andnon-invasive diagnostic tool that can be successfully used by local, non- urologist physicians at the point-of-care to provide a highly effective PCa screening and as an additional confirmatory test before a prostate gland biopsy. 展开更多

Two rice cultivars(Xiushui 09 and Chunyou 84)were used to evaluate the effects of various soil oxygen(O2)conditions on soil nitrogen(N)transformation,absorption and accumulation in rice plants.The treatments were continuous flooding(CF),continuous flooding and aeration(CFA),and alternate wetting and drying(AWD).The results showed that the AWD and CFA treatments improved soil N transformation,rice growth,and N absorption and accumulation.Soil NO3–content,nitrification activity and ammonia-oxidising bacteria abundance,leaf area,nitrate reductase activity,and N absorption and accumulation in rice all increased in both cultivars.However,soil microbial biomass carbon and pH did not significantly change during the whole period of rice growth.Correlation analysis revealed a significant positive correlation between the nitrification activity and ammonia-oxidising bacteria abundance,and both of them significantly increased as the total N accumulation in rice increased.Our results indicated that improved soil O2 conditions led to changing soil N cycling and contributed to increases in N absorption and accumulation by rice in paddy fields. 展开更多

The Cameroonian daily press is now taking a new look at the use of photography in its columns. Photography is therefore at the heart of the new information system: the application of a new formula, a photographic formula, therefore visual, which is a novelty. The aim of our article is to highlight how the Cameroonian daily press constructs the discursive staging of this visual content. It proposes to examine the ways in which the news image in <i>Cameroon Tribune</i> is constituted in journalistic writing. In this article, we will analyse the photographic content of the daily newspaper <i>Cameroon Tribune</i>. The corpus consists of 1245 photographs from 25 issues published between 21 October and 22 November 2019. The technique used is media content analysis, which allows us to produce exhaustive descriptive statements that meet the criteria of scientific validity and reproducibility. Emancipated from its strict illustrative function, photography in the daily newspaper <i>Cameroon Tribune</i> then becomes fully a means of information and communication, in the same way as text. This translates into the construction of informative sets such as the importance of the surface area of the visual content which gives pride of place to the visual, giving an impression of abundance that is perceptible from the Front Page. One of the important features of the newspaper’s iconography is the great positivity of its images, which reinforces the closeness between the reader and the news. In total, the newspaper highlights photographs of limited informative interest: these are portraits that show the faces of the protagonists of the articles, to the detriment of current events. 展开更多

To characterize the effects of plantation densities on the growth characteristics(diameter at breast level,tree height and volume) and the common wood properties,38-year-old Populus simonii 9 P.nigra clones planted with four levels of spacing(2 m × 2 m,3 m × 3 m,4 m × 4 m,and 5 m × 5 m) in a semi-arid area in northeastern China were examined.The results of ANOVA showed significant differences(P<0.01) for all the investigated growth traits and wood properties under different plantation densities,except for the chemical composition of wood.The repeatability and phenotypic variations of all the traits varied from 0.34 to 0.99 and from 13.45 to 59.65%,respectively.Except for wood density,which was significantly negatively correlated with the growth traits,a positive correlation was observed between the growth traits and all the other wood mechanical properties.However,most of the correlations between the growth traits and the chemical composition of the wood were not significant.The path analysis for the wood mechanical characteristics and the growth in the prediction of volume were significant and ranged from 0.18 to 0.72 for wood density and diameter at breast height,respectively,while those for the chemical composition of wood ranged from 0.001 to 0.336,which showed a low impact on the volume.The highest stand volume(610 m~3) per hectare was observed with the 2 m × 2 m spacing,which consequently provided a high total price and income,while a high individual volume growth per tree was observed with the 5 m × 5 m spacing.The results suggested that for the poplar trees younger than 40 years in a semi-arid area in China,2 m × 2 m spacing is suitable for obtaining a high volume per hectare,while 5 m × 5 m spacing is best for obtaining a high individual volume per tree. 展开更多

The limited number of studies on mixed plantations makes it difficult to accurately predict success of mixed-species combination especially with regards to growth, undergrowth diversity and carbon sequestration potentials. This study therefore provides information on the effects of Ceiba pentandra, Terminalia superba, Cedrela odorata and Khaya anthotheca in three different stand combinations on growth, undergrowth diversity and carbon sequestration potential. A 15-year-old coupe of 32 ha of mixed tree species stand combinations was selected for the study. The coupe was stratified based on the species combinations. Nested sub-plots (25 m × 25 m) were randomly laid in different species stand combinations for growth data collection. In each nested sub-plot, 1 m × 1 m plots were also randomly laid for undergrowth diversity study. The results revealed that two species stand combination of Ceiba pentandra and Terminalia superba performed better in terms of growth, carbon sequestration and carbon content as compared to the other species stand combinations. The saplings on the other hand, were more diverse under the three species stand combination plots. Also, the effective number of species, species richness, evenness, and dominance were higher in the four species stand combination plots. Generally, Ceiba pentandra and Terminalia superba are compatible as it produced the highest growth and carbon sequestration potential. 展开更多

Indica-japonica hybrid rice(Oryza sativa L.) cultivars showed high yield potential and poor tasting quality when compared with common japonica rice cultivars. Large panicle is a prominent factor of high yield for indica-japonica hybrid rice cultivars, and the panicle weight varies greatly among different indica-japonica hybrid rice cultivars. It is important to research on yield and grain quality of different panicle weight indica-japonica hybrid rice cultivars. In this study, two different panicle types indica-japonica hybrid cultivars were used to research on the relation of yield and grain quality. The yields of two heavy panicle weights indica-japonica hybrid cultivars were significantly higher than that of two medium panicle weight rice cultivars. The cooking and eating quality and starch properties of different panicle type cultivars were evaluated. Yongyou 6715(medium panicle) and Yongyou 1852(heavy panicle) got the relatively higher cooking and eating quality. Rice cultivars with medium panicle weight had more large starch granules and higher relative crystallinity than cultivars with heavy panicle weight. Transition temperature and retrogradation enthalpy(ΔHret) of medium panicle type cultivars were significantly higher than that of heavy panicle type cultivars. There was no significant difference in amylose content among different panicle type cultivars. Protein content of heavy panicle type cultivar was higher than that of medium panicle type cultivar, and protein content is the main factor affect cooking and eating quality in this study. The cultivar Yongyou 6715 got the highest taste value with the lowest protein content. Thus, it is suggested that the emphasis on improving rice cooking and eating quality of indica-japonica hybrid rice cultivars is how to reduce the protein content in rice grain. According to the results of this study, medium panicle type with high grain weight is the desired panicle type for high quality indica-japonica hybrid rice breeding. 展开更多
