Research on the improvement of the core competitiveness of tea industry in famous tea town: A case study of Huangshan City, Anhui Province
Authors: Jiang N 
Published: October 2019

Abstract
Huangshan City, Anhui Province, is one of the most suitable tea producing areas in China, with a long history of tea making. There are many varieties of tea in Huangshan, such as Maofeng, Taiping Houkui, Qimen black tea and so on. Tea industry is an important economic pillar of Huangshan City. However, statistics in recent years show that there are obvious shortcomings in the quantity and quality of tea production in Huangshan City, and the development in domestic sales and export is slow. In this paper, the diamond model proposed by Professor Michael Porter is used to analyze the competitiveness of tea industry in Huangshan City from six aspects: production factors, demand situation, related and supporting industries, enterprise strategy and structure, as well as inter-industry competition, government and opportunity. It is suggested to try to promote the operation mode of "Leading Enterprises + Production Cooperatives + Farmers + Traditional Channels + Internet +", so as to form a more complete local tea industry chain and help more local tea farmers to increase income and become rich. Furthermore, relying on the rich tourism and cultural resources in the region, this paper tries to explore a unique development path that combines tea garden experience, tea culture and local tourism, highlights local characteristics and advantages, and seeks an optimized model suitable for the development of local tea industry.

Authors: Paethaisong W , Lontom W , Dongsansuk A 
Published: October 2019

Abstract
High temperature is an important limiting factor for the growth and development of rice cultivation worldwide. The current research aimed to investigate the efficiency of PSII system, photosynthetic changes in photosynthetic pigments and membrane stability in Thai seedlings of Thai rice cv. Riceberry after exposure to different temperatures viz., 25, 30, 35, 40, 45, 50 and 55°C for 30 min. The experiment was designed in CRD with four replications. The results showed that the highest Fv/Fm
was realized when seedlings were exposed to 30°C and 35°C and decreased when exposed to 40°C for 30 min. The content of photosynthetic pigments such as total chlorophyll (TC) and chlorophyll a (Chl a) were the highest after short-term exposure to a temperature of 25°C. However, the contents of all photosynthetic pigment such as TC, Chl a, Chl b and carotenoids were the lowest when exposed to 55°C for 30 min. The membrane stability of Riceberry seedlings affected on short-term exposure to temperatures of 50°C and 55°C. Thus, Fv/Fm and Hill reaction were the first mechanisms to be significantly affected by the short-term exposure to a temperature of 40°C followed by membrane stability and contents of photosynthetic pigments which were affected by short-term exposure to temperature of 50°C -55°C and 55°C, respectively.

Authors: Zhao H B , Zhou X H 
Published: October 2019

Abstract
There are often mobile, unconscientious vendors in China who sell stale or even rotten eggs in produce markets, earning money by dishonest means. To prevent the entry of substandard eggs into the market that endanger the health of consumers, we designed an egg freshness recognition system based on a fuzzy radial-basis-function (RBF) neural network. This system acquires the color characteristic parameters red (R), green (G), and blue (B) of the transmitted light of eggs through a computer vision device. The system converts the RGB values into HIS (hue, intensity, and saturation) values, uses the egg transmitted light color characteristic parameter HIS as an input value and employs the Huff value coding as an output. A test sample was used to verify the identification system. Our experimental results show that when using a fuzzy RBF neural network and simple RBF neural network algorithm, the average recognition accuracy of the system is 96.35% and 92.72%, respectively, both of which are higher than the average recognition accuracy of 88.14% when using the back propagation neural network algorithm. The feasibility and superiority of the identification system proposed in this paper were verified; therefore, this system may serve as a reference for future research on egg freshness recognition.

Published: October 2019

Abstract
The Myric rubra leaves essential oil (MEO) was extracted by steam distillation and its major component was analyzed by gas chromatography mass spectrum (GC-MS). The result showed that 20 kinds of essential oils were identified. with humulene (26.03%), caryophyllene (19.74%), ledene oxide-(II) (16.37%) and γ-himachalene (7.7%) being the major constituents. The antioxidant activity of MEO were analyzed by 2,2-diphenyl-1-picrylhydrazylassay (DPPH) and oxygen radical absorbance capacity (ORAC) assay respectively, Analogues of vitamin E (Trolox) was positive control. The results showed that the IC50 of DPPH radical scavenging is 0.0576 mg/mL and the ORAC value of fluorescence spectrometry is 1.32mmol TE/g. The anticancer effect of obtained MEO was tested in A549 lung cancer cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. MEO IC50 value of 163 μg/mL was obtained with significantly inhibited cell proliferation in concentration-dependant manner. MEO could be useful for pharmaceutical, food and cosmetic industry, because of its strong antioxidant and anticancer activity.

Authors: Kostromin S V , Podshivalov A , Asandulesa M , Bronnikov S 
Published: October 2019

Abstract
We produced nanocomposites comprised of polyazomethine and reduced graphene oxide by solution mixing. The nanofiller concentration ranged from 0.25 to 1.5 wt.%. Both neat polymer and nanocomposites samples were investigated using broadband dielectric spectrometry under the same conditions. The electrical conductivity σ of the samples was examined as a complex value being a combination of two parameters: dc conductivity (σdc
) and ac conductivity (σac
). The temperature dependences of σac
were found to follow the Arrhenius equation, whereas the frequency dependences of σac
were shown to obey a power law. We proposed that the correlated barrier hopping could explain behaviour of σac
of the nanocomposites under study.

Published: October 2019

Abstract
Recycled aggregate (RA) was obtained from waste cement concrete brick with the method of crushing and sieving. In order to research the effect of RA content on the properties of pervious concrete, RA was added to replace natural aggregate with equivalent quality method at different levels (25%, 50%, 75% and 100%). The natural aggregate pervious concrete and RA pervious concrete were prepared in the lab. The porosity, permeability, compressive strength, flexural strength and freeze-thaw (F-T) durability of RA pervious concrete were tested. The results indicated that the compressive strength and flexural strength of RA pervious concrete decreased with the increase of RA content. The rapid decreases for compressive strength and flexural strength occurred when the RA content was 25%-75% and 0%-25%, respectively. The porosity and permeability decreased slowly with the increasing RA content. F-T durability of RA pervious concrete was poorer than the natural aggregate pervious concrete. The incorporation levels had negative effect on the F-T durability, but the compressive strength loss of all groups after 25 F-T cycles met the requirement of the national standard. Although the mechanical properties and F-T durability of RA pervious concrete are not satisfied, it can still be used for sidewalks, parks and other light traffic roads.

Authors: Ujah C O , Popoola A P , Popoola O M 
Published: October 2019

Abstract
Unreinforced Al alloy lacks adequate tribological property required in service. To improve on this property, it must be reinforced with materials having good wear properties. Hence, Al was reinforced with CNTs and Nb and consolidated with spark plasma sintering (SPS). The wear experiment was conducted on a ball-on-disc Tribometer where loads of 10 N, 20 N and 30 N were systematically applied. The coefficients of friction (COF) of the sintered samples were subsequently obtained. The samples were weighed before and after each run to determine their weight losses which were used to compute their wear volumes. The experiment was designed and analyzed with Taguchi and ANOVA. Results showed that Al-8CNTs-8Nb composite had the best wear characteristics. Its COF got improved by 79% which shows that it is suitable for industrial applications.
Computational screening of functional monomers for bitertanol sensing using molecularly imprinted polymer
Authors: Cayabyab C A L , Pajarito B B 
Published: October 2019

Abstract
Pesticide residue monitoring in agricultural products is required by governments and organizations to minimize its toxic effects of pesticides in humans. Bitertanol is a fungicide used in various crops to control plant diseases but also poses harmful consequences in human health when misused. Molecularly imprinted polymers (MIPs) are artificial materials that can be used to selectively isolate and recover this substance from contaminated crops. In this work, we determined the best monomer to imprint bitertanol by evaluating the interaction between different functional monomers and bitertanol in the pre-polymer complex. Density functional theory used to optimize the structure of the complex and evaluate the interaction. The computational results showed that hydroquinone produces the most stable complex at 1:3 template-monomer ratio. The hydroxyl functionalities of hydroquinone can effectively form hydrogen bonds with the triazole ring and the hydroxyl group of bitertanol. Furthermore, parameters such as Mulliken atomic charges, bond lengths, and frontier molecular orbitals were also evaluated to confirm the formation of stable hydrogen bonds. This study can be used as a theoretical foundation for the preparation of MIPs for bitertanol using.
A League to Preserve Empires: Understanding the Mandates System and Avenues for Further Scholarly Inquiry
Authors: Wempe Sean Andrew 
Published: October 2019

Abstract
A century after the victorious Allied powers distributed their spoils of victory in 1919, the world still lives with the geopolitical consequences of the mandates system established by the League of Nations. The Covenant article authorizing the new imperial dispensation came cloaked in the old civilizationist discourse, entrusting sovereignty over “peoples not yet able to stand by themselves under the strenuous conditions of the modern world” to the “advanced nations” of Belgium, England, France, Japan, and South Africa. In this series of “reflections” on the mandates, ten scholars of Europe, Africa, the Middle East, Asia, and the international order consider the consequences of the new geopolitical order birthed by World War I. How did the reshuffling of imperial power in the immediate postwar period configure long-term struggles over minority rights, decolonization, and the shape of nation-states when the colonial era finally came to a close? How did the alleged beneficiaries—more often the victims—of this “sacred trust” grasp their own fates in a world that simultaneously promised and denied them the possibility of self-determination? From Palestine, to Namibia, to Kurdistan, and beyond, the legacies of the mandatory moment remain pressing questions today.
Whorf in the Wild: Naturalistic Evidence from Human Interaction
Authors: Athanasopoulos Panos , Bylund Emanuel 
Published: October 2019

AbstractThe past few decades have seen a full resurgence of the question of whether speakers of different languages think differently, also known as the Whorfian question. A characteristic of this neo-Whorfian enterprise is that the knowledge it has generated stems from psycholinguistic laboratory methods. As a consequence, our knowledge about how Whorfian effects play out in naturally occurring behaviour (i.e. ‘in the wild’) is severely limited. This study argues that the time is ripe to redeem this evidentiary bias, and advocates a multidisciplinary approach towards the Whorfian question, in which insights from laboratory settings are combined with naturalistic data in order to yield a rounded picture of the influence of language on thought. To showcase the potential of such an approach, the study uses laboratory-generated knowledge on the influence of grammatical categories on cognition to interpret two examples of naturalistic human interaction and action in the domains of spatial navigation and scientific practice.

Abstract

Summary
Alternative splicing is an important biological process widely analyzed in molecular diagnostic settings. Indeed, a variant can be pathogenic by splicing alteration and a suspected pathogenic variant (e.g. truncating variant) can be rescued by splicing. In this context, detecting and quantifying alternative splicing is challenging. We developed SpliceLauncher, a fast and easy to use open source tool that aims at detecting, annotating and quantifying alternative splice junctions at high resolution.

Visual and olfactory floral cues related to ambophilous pollination systems in Poaceae
Authors: Schulze-Albuquerque Isadora , Costa Ana Carolina Galindo Da , Milet-Pinheiro Paulo , Navarro Daniela Maria Do Amaral Ferraz , Thomas William Wayt , Machado Isabel Cristina 
Published: October 2019

Abstract
Usually considered anemophilous, grasses (Poaceae) have been the subject of few studies that recorded insects visiting their flowers. Such visitors, with wind, could act as pollen vectors in a possible ambophilous system. Since colour and scent are floral cues attracting pollinating insects, we aimed to provide the first insights into how these cues could be involved in the attraction of pollinators by grasses. Chloris barbata, Paspalum maritimum (with two morphotypes), P. millegrana and Urochloa plantaginea were studied. We determined the role of each pollen vector (wind and insect) and we registered the frequency of floral visitors. Also, we characterized the colour reflectance of glumes, anthers and stigmas and we determined the colour space in the bee colour hexagon and the chemical composition of floral scents. The floral structures of each species reflect colour differently and are perceived differently by pollinators. Furthermore, the volatile organic compounds detected are similar to those found in entomophilous species. In two of the grass species, we registered eight species of visitors, including bees, wasps and flies. Overall, wind was the most important vector for reproductive success. Insects, however, may induce wind pollination by creating pollen clouds when they visit inflorescences.

Abstract

Background
Enhanced influenza vaccines may improve protection for older adults, but comparative immunogenicity data are limited. Our objective was to examine immune responses to enhanced influenza vaccines, compared to standard-dose vaccines, in community-dwelling older adults.

Methods
Community-dwelling older adults aged 65–82 years in Hong Kong were randomly allocated (October 2017–January 2018) to receive 2017–2018 Northern hemisphere formulations of a standard-dose quadrivalent vaccine, MF59-adjuvanted trivalent vaccine, high-dose trivalent vaccine, or recombinant-hemagglutinin (rHA) quadrivalent vaccine. Sera collected from 200 recipients of each vaccine before and at 30-days postvaccination were assessed for antibodies to egg-propagated vaccine strains by hemagglutination inhibition (HAI) and to cell-propagated A/Hong Kong/4801/2014(H3N2) virus by microneutralization (MN). Influenza-specific CD4+ and CD8+ T cell responses were assessed in 20 participants per group.

Results
Mean fold rises (MFR) in HAI titers to egg-propagated A(H1N1) and A(H3N2) and the MFR in MN to cell-propagated A(H3N2) were statistically significantly higher in the enhanced vaccine groups, compared to the standard-dose vaccine. The MFR in MN to cell-propagated A(H3N2) was highest among rHA recipients (4.7), followed by high-dose (3.4) and MF59-adjuvanted (2.9) recipients, compared to standard-dose recipients (2.3). Similarly, the ratio of postvaccination MN titers among rHA recipients to cell-propagated A(H3N2) recipients was 2.57-fold higher than the standard-dose vaccine, which was statistically higher than the high-dose (1.33-fold) and MF59-adjuvanted (1.43-fold) recipient ratios. Enhanced vaccines also resulted in the boosting of T-cell responses.

Conclusions
In this head-to-head comparison, older adults receiving enhanced vaccines showed improved humoral and cell-mediated immune responses, compared to standard-dose vaccine recipients.

Practical Attribute-Based Conjunctive Keyword Search Scheme
Authors: Chen Yang , Li Wenmin , Gao Fei , Liang Kaitai , Zhang Hua , Wen Qiaoyan 
Published: October 2019

AbstractTo date cloud computing may provide considerable storage and computational power for cloud-based applications to support cryptographic operations. Due to this benefit, attribute-based keyword search (ABKS) is able to be implemented in cloud context in order to protect the search privacy of data owner/user. ABKS is a cryptographic primitive that can provide secure search services for users but also realize fine-grained access control over data. However, there have been two potential problems that prevent the scalability of ABKS applications. First of all, most of the existing ABKS schemes suffer from the outside keyword guessing attack (KGA). Second, match privacy should be considered while supporting multi-keyword search. In this paper, we design an efficient method to combine the keyword search process in ABKS with inner product encryption and deploy several proposed techniques to ensure the flexibility of retrieval mode, the security and efficiency of our scheme. We later put forward an attribute-based conjunctive keyword search scheme against outside KGA to solve the aforementioned problems. We provide security notions for two types of adversaries and our construction is proved secure against chosen keyword attack and outside KGA. Finally, all-side simulation with real-world data set is implemented for the proposed scheme, and the results of the simulation show that our scheme achieves stronger security without yielding significant cost of storage and computation.

Published: October 2019

SUMMARY
The Swedish National Register for Esophageal and Gastric cancer was launched in 2006 and contains data with adequate national coverage and of high internal validity on patients diagnosed with these tumors. The aim of this study was to describe the evolution of esophageal and gastric cancer care as reflected in a population-based clinical registry. The study population was 12,242 patients (6,926 with esophageal and gastroesophageal junction (GEJ) cancers and 5,316 with gastric cancers) diagnosed between 2007 and 2016. Treatment strategies, short- and long-term mortality, gender aspects, and centralization were investigated. Neoadjuvant oncological treatment became increasingly prevalent during the study period. Resection rates for both esophageal/GEJ and gastric cancers decreased from 29.4% to 26.0% (P = 0.022) and from 38.8% to 33.3% (P = 0.002), respectively. A marked reduction in the number of hospitals performing esophageal and gastric cancer surgery was noted. In gastric cancer patients, an improvement in 30-day mortality from 4.2% to 1.6% (P = 0.005) was evident. Overall 5-year survival after esophageal resection was 38.9%, being higher among women compared to men (47.5 vs. 36.6%; P &lt; 0.001), whereas no gender difference was seen in gastric cancer. During the recent decade, the analyses based on the Swedish National Register for Esophageal and Gastric cancer database demonstrated significant improvements in several important quality indicators of care for patients with esophagogastric cancers. The Swedish National Register for Esophageal and Gastric cancer offers an instrument not only for the control and endorsement of quality of care but also a unique tool for population-based clinical research.
