Helicobacter pylori Infection and Hepatobiliary Pathology
Authors: German S. V. , Bobrovnitsky I. P.
Published: September 2018

Aim.  The aim of this review is to analyze and systematize data on the effect of Helicobacter pylori infection on hepatobiliary diseases.

Background.  Over the past two decades, a growing number of studies have been devoted to the possible involvement of H. pylori infection in the extragastric pathology. The presence of the bacterium was detected in many organs and tissues. Its relationship with the development of idiopathic iron-deficiency anemia, B12 deficiency anemia, idiopathic thrombocytopenic purpura is proved. The possible role of the bacterium in the development of hepatobiliary pathology is also discussed. The presence of the bacterium has been revealed in samples taken from the liver tissue, biliary tract, bile and gallstones of patients suffering from hepatobiliary diseases. The involvement of H. pylori in the formation of gallstones is considered possible. Non-alcoholic fatty liver disease (NAFLD) is more often diagnosed in H. pylori infected individuals compared to those not infected. The progression of inflammation in the liver of any nature is noted in the presence of H. pylori infection. Different species of the Helicobacter genus, including H. pylori, are shown to contribute to the development of liver cancer. However, some researchers report data against the involvement of H. pylori in the pathogenesis of various hepatobiliary diseases.

Conclusion. The results obtained by the authors cannot be considered unambiguous, thus requiring further research. Given the high prevalence of H. pylori infection and the significant incidence of hepatobiliary pathology, the confirmation of their relationship can be of great epidemiological, preventive and clinical importance.

This paper is aimed at investigating the microbiota of the esophagus and stomach in patients with gastroesophageal reflux disease (GERD) and healthy volunteers.

Materials and methods.  The study included 15 patients suffering from GERD and 6 healthy volunteers. All subjects underwent sampling of esophageal and gastric contents. The study of the microbiota in the obtained samples was performed by sequencing the 16S gene of ribosomal RNA (rRNA).

Results. The most common types of bacteria in the esophagus and stomach in patients with GERD and healthy volunteers are found to be Bacteroidetes, Firmicutes, Actinobacteria, Proteobacteria, Fusobacterium. By comparing the relative contents of the main types of bacteria in the esophageal mucus and gastric contents, a significant decrease in the proportion of Proteobacteria was observed in patients with GERD as compared to healthy volunteers. The decrease in the relative number of bacteria belonging to the Acetobacteraceae, Bacillaceae, Bdellovibrionaceae, Clostridiales Insertae Sedis XI, Fusobacteriaceae, Moraxellaceae, Pasteurellaceae and Rhodocyclaceae families was observed in the esophagus in patients with GERD as compared to healthy volunteers. A higher bacterial content of the Leptotrichiaceae and Veillonellaceae families was detected in the stomach of patients with GERD.

Conclusions.  The obtained results indicate differences in the intraluminal microbiota of the esophagus and stomach in patients with GERD and healthy volunteers. Further study should be carried out to study the effect of changes in bacterial composition on those in the esophagus and stomach.
HTSCC A Hybrid Task Scheduling Algorithm in Cloud Computing Environment
Authors: Al-Arasi Rasha Ali , Saif Anwar
Published: September 2018

Nowadays, cloud computing makes it possible for users to use the computing resources like application, software, and hardware, etc., on pay as use model via the internet. One of the core and challenging issue in cloud computing is the task scheduling. Task scheduling problem is an NP-hard problem and is responsible for mapping the tasks to resources in a way to spread the load evenly. The appropriate mapping between resources and tasks reduces makespan and maximizes resource utilization. In this paper, we present and implement an independent task scheduling algorithm that assigns the users' tasks to multiple computing resources. The proposed algorithm is a hybrid algorithm for task scheduling in cloud computing based on a genetic algorithm (GA) and particle swarm optimization (PSO). The algorithm is implemented and simulated using CloudSim simulator. The simulation results show that our proposed algorithm outperforms the GA and PSO algorithms by decreasing the makespan and increasing the resource utilization.
Calcareous algae from the Ordovician succession (Thango Formation) of the Spiti Basin, Tethys Himalaya, India
Authors: Pandey Shivani , Parcha Suraj K.
Published: September 2018

The calcareous algae Dasyporella silurica, Moniliporella multipora and Vermiporella fragilis are reported for the first time from the Middle Ordovician (Dapingian to Darriwilian) Thango Formation of the Spiti Basin of northern India (Pin Valley, Tethys Himalaya). Moniliporella multipora is reported for the first time from the entire Spiti Basin. This algal assemblage is broadly comparable to that of the directly overlying Takche (=Pin) Formation in the Spiti Basin, as well as that reported from the Ordovician succession of the Tarim Basin and from Kazakhstan. The presence of these calcareous algae is of biogeographical and biostratigraphical significance as it indicates a shallow marine depositional environment for the Thango Formation of the Spiti Basin.
Correlates of rural development: A case study of Sadar development block of Pratapgarh District in Uttar Pradesh, India
Authors: Mishra Ashutosh
Published: September 2018

Rural development aims at improving the quality of life of rural people, and in the process infrastructure variables play a crucial role. India is the second most populous country in the world and the majority of its population lives in rural areas. Rural development has been India’s prime concern ever since the time of independence, and several strategies and plans were implemented from time to time to achieve a better level of development. However, neither top-down, nor bottom-up strategies of development could bring the desired changes. This article attempts to identify some correlates of rural development and tries to understand why the desired level and pattern of development could not be achieved even after seven decades of the planning process. The study analyses the case of ‘Sadar’ development block of Pratapgarh district in Uttar Pradesh. The analysis of 10 selected variables reveals that there is a vast disparity in the level of development in the study area. However, the study shows that lack of basic education, health and credit facilities is the cause of this disparity and poor level of development. In view of the findings the author suggests that a ‘local resource-oriented development strategy’ should be adopted to ensure the holistic development of the rural areas.

Authors: Liu Bin , Li Zhongbin
Published: September 2018

Purpose – This study aimed to assess the impact of director-generals’ human and social capitals on the organizational performance of farmers’ cooperatives in Fujian Province. Design/Methodology/Approach – Questionnaire survey data of 303 standard cooperatives in nine cities of Fujian Province were statistically analyzed.

Findings – We identified that director-generals’ human and social capitals affect all four dimensions of cooperative performance, through the mediating role of management effectiveness.

Practical Implications – We offer suggestions and measures for improving cooperatives’ performance by enhancing the human and social capitals of director-generals. Based on China’s national conditions, we propose measures to improve director-generals’ human and social capitals by the Internal trust, Government policy support, and Business network (IGB) model, which emphasizes establishing a social network of cooperatives’ director-generals, accumulating social capital, and promoting cooperative development through internal members, government departments, and commercial organizations.
Predicates of personal taste in communication: A case of disagreement
Authors: Zouhar Marián
Published: September 2018

The aim of the paper is to defend the idea that, from the semantic point of view, predicates of personal taste behave in communication like ordinary indexical expressions (pronouns, demonstratives, etc.). It means that they express different semantic contents relative to relevantly different contexts of utterances. This is a consequence of the claim that “tasty” (which is our paradigm example of a predicate of personal taste) and “tasty for (someone)” (where “someone” is a placeholder for an agent) express the same, or very similar, semantic contents relative to the same context of utterance. Now this idea can be challenged by pointing to certain communicative phenomena, such as disagreements about matters of personal taste. It is argued, however, that there is an explanation of taste disagreements that is compatible with the indexical nature of predicates of personal taste. Moreover, it is shown that an explanation along these lines is rather natural because it seems to be necessitated by communication-based evidence.
Integrationist semiology and text theory
Authors: Gvoždiak Vít
Published: September 2018

The aim of this paper is (1) to briefly define the essence of integrationist semiology/linguistics (especially in Roy Harris’ works – e.g. Harris 1981, 1984, 1998a) and to present a set of basic methodological beliefs that can be considered as a principal critique of traditional (so called segregationist) linguistics / semiology. Among the most important integrationist beliefs are the non-privilege of linguistic acts in human communication (the principle of contemporality), contextualism (the sign form is not independent of the sign substance) and the inseparability of rules from their application. On this basis the paper (2) outlines the basic aspects of integrationist convictions about the relationship between the sign and the text and their comparison with Rastier’s (2015) interpretative semantics. In conclusion (3) the article discusses one current form of the philosophy of language (Pettersson, 2017) that is – to a certain extent – based on integrationism. Overall, the paper attempts to draw attention to the fact that integrationist theory in many cases provides an adequate critical reflection of traditional semiological/linguistic methodology, but in a closer look it shows that it cannot offer a robust theoretical alternative.
Linguistic knowledge and command of language
Authors: Dolník Juraj
Published: September 2018

Drawing on the ideas of many pragmatically based philosophers of language and linguistics, the author proposes a conception of command of language with regard to linguistic cultivation of language users. His approach to the problem may be summarized in the sentence that the cultivation of the mother tongue is adequate when it is in harmony with communicative rationality that originated from the fact that human beings are behavioural-actional creatures. The main point is that the rationality of communication is based on the function of the intention-emergent-mechanism; that is, we are in natural linguistic state if the working of this mechanism is not disturbed. The cultivation of command of language can only be successful as the developing of the natural linguistic state when the requirement of the natural coordination of the behavioural and actional linguistic competence remains in force, in other words, it is necessary to take into consideration that for the natural command of language is responsible the interplay of the not-knowledge-based grammatical disposition and the language knowledges.
Accounting for Spatial Variation of Land Prices in Hedonic Imputation House Price Indices: a Semi-Parametric Approach
Authors: Gong Yunlong , de Haan Jan
Published: September 2018

Location is capitalized into the price of the land the structure of a property is built on, and land prices can be expected to vary significantly across space. We account for spatial variation of land prices in hedonic house price models using geospatial data and a semi-parametric method known as mixed geographically weighted regression. To measure the impact on aggregate price change, quality-adjusted (hedonic imputation) house price indices are constructed for a small city in the Netherlands and compared to price indices based on more restrictive models, using postcode dummy variables, or no location information at all. We find that, while taking spatial variation of land prices into account improves the model performance, the Fisher house price indices based on the different hedonic models are almost identical. The land and structures price indices, on the other hand, are sensitive to the treatment of location.
Acceptorless amine dehydrogenation and transamination using Pd-doped layered double hydroxides
Authors: Ainembabazi Diana , An Nan , Manayil Jinesh , Wilson Karen , Lee Adam , Voutchkova-Kostal Adelina
Published: September 2018

The synthesis, characterization, and activity of Pd-doped layered double hydroxides (Pd-LDHs) for for acceptorless amine dehydrogenation is reported. These multifunctional catalysts comprise Brønsted basic and Lewis acidic surface sites that stabilize Pd species in 0, 2+, and 4+ oxidation states. Pd speciation and corresponding cataytic performance is a strong function of metal loading. Excellent activity is observed for the oxidative transamination of primary amines and acceptorless dehydrogenation of secondary amines to secondary imines using a low Pd loading (0.5 mol%), without the need for oxidants. N-heterocycles, such as indoline, 1,2,3,4-tetrahydroquinoline, and piperidine, are dehydrogenated to the corresponding aromatics with high yields. The relative yields of secondary imines are proportional to the calculated free energy of reaction, while yields for oxidative amination correlate with the electrophilicity of primary imine intermediates. Reversible amine dehydrogenation and imine hydrogenation determine the relative imine:amine selectivity. Poisoning tests evidence that Pd-LDHs operate heterogeneously, with negligible metal leaching; catalysts can be regenerated by acid dissolution and re-precipitation.
SemiEmpirical Born-Oppenheimer Molecular Dynamics (SEBOMD) Within the Amber Biomolecular Package
Authors: Marion Antoine , Gokcan Hatice , Monard Gerald
Published: September 2018

Semiempirical quantum methods from the Neglect of Differential Diatomic Overlap (NDDO) family such as MNDO, AM1, or PM3 are fast albeit approximate quantum methods. By combining them with linear scaling methods like the Divide & Conquer (D&C) method, it is possible to quickly evaluate the energy of systems containing hundreds to thousands of atoms. We here present our implementation in the Amber biomolecular package of a SEBOMD module that provides a way to run SemiEmpirical Born-Oppenheimer Molecular Dynamics. At each step of a SEBOMD molecular dynamics, a fully converged SCF calculation is performed to obtain the semiempirical quantum potential energy of a molecular system encaged or not in periodic boundary conditions. We describe the implementation and the features of our SEBOMD implementation. We show the equirements to conserve the total energy in NVE simulations, and how to accelerate SCF convergence through density matrix extrapolation. Specific ways of handling periodic boundary conditions using mechanical embedding or electrostatic embedding through a tailored quantum Ewald summation is developed. The parallel performance of SEBOMD simulations using the D&C scheme are presented for liquid water systems of various sizes, and a comparison between the traditional full diagonalization scheme and the D&C approach for the reproduction of the structure of liquid water illustrates the potentiality of SEBOMD to simulate molecular systems containing several hundreds of atoms for hundreds of picoseconds with a quantum mechanical potential in a reasonable amount of CPU time.

The phenomenon of crystallization is poorly understood and yet is critical to the design of new materials, such as metal-organic frameworks (MOFs), for which predictive formation mechanisms remain elusive. We report a tandem in situ X-ray diffraction and pH investigation into the prototypical MOF, ZIF-8, in which it is found that the crystallization mechanism changes from phase boundary-limited to diffusion-limited across the course of each reaction, and crystallization rates decrease with increasing concentration. These counterintuitive observations are explained using a non-linear pre-equilibrium model, in which network formation depends on the rates of Zn-imidazole coordination and imidazole deprotonation. Whilst assembly of under-coordinated species is associative and fast, over-coordinated species act to inhibit network formation. The work rationalises apparent contradictions between previous studies and opens up new opportunities for the creation of MOFs with control over particle size, composition and local structure.

Published: September 2018

We have studied the composition and morphology of Ni-Mo alloys. These alloys consist of a Ni-rich core surrounded by Mo-rich oxide layer. The HER activity of Ni-Mo alloys was seen to be limited by interfacial resistance rather than kinetic and solution transport. Vulcan carbon, a conductive support mitigate the resistive limitations by providing conductive percolation networks.
Reaction Networks in Propane Ammoxidation to Acrylonitrile Over Orthorhombic Mo-V-Nb-Te-O Catalyst
Authors: Bhatt Salil , Khang Soon-Jai , Guliants Vadim
Published: September 2018

We investigated propane ammoxidation to acrylonitrile over hydrothermal Mo-V-Nb-TeO catalyst containing the dominant M1 phase, recently proposed as active and selective in this selective ammoxidation reaction. The reaction kinetics was studied in a tubular quartz reactor at 600-700K operated in both differential and integral regimes at 5-60% propane conversion. The results obtained in this study were examined on the basis of two reaction networks involving propane transformation via (1) parallel routes to propylene, acrylonitrile and carbon oxides and (2) propylene as the reaction intermediate for acrylonitrile. The results obtained indicated only a slight preference for the reaction network involving the propylene intermediate, which may be explained on the basis of catalytic behavior of the M1 and M2 phases present in the hydrothermal Mo-V-Nb-Te-O catalyst. The dominant M1 phase was capable of catalyzing all of the above transformation steps, whereas the M2 impurity phase was only active in propylene ammoxidation to acrylonitrile. The contribution of the M2 phase to propylene ammoxidation is expected to be less significant at industrially relevant high propane conversions because of the improved ability of the M1 phase to covert propylene into acrylonitrile at longer residence times.

Published: September 2018

Jabodetabek and Bandung Raya metropolitan region experienced an urban expansion phenomenon that caused the two metropolitan regions to become increasingly connected by a corridor and form a mega-urban region caused by the conurbation process. Purwakarta regency is one of the regions in Jakarta-Bandung corridor that experienced the impact of Jakarta-Bandung conurbation process. This study aims to analyze the level of regional development, to analyze land cover change that occurred, and to predict Purwakarta Regency land use/land cover in 2030. Regional development analysis is done by using the Scalogram method based on Potential Village data of year 2003 and 2014. Land cover change analysis is done through spatial analysis by overlaying land cover Landsat Satellite Image of year 2000 and 2015. Land use/land cover prediction in 2030 is conducted through spatial modelling of Cellular Automata Markov method. Purwakarta Regency experienced an increase in regional development within the period of 11 years (2003 to 2014), which is marked by a decrease in the percentage of the number of villages that are in hierarchy III and increase in the percentage of the number of villages that are in hierarchy II and I. In general, within 15 years (2000 to 2015) Purwakarta Regency has increasing number of built-up area and mixed gardens, meanwhile dry land, forest, paddy field, and water bodies tend to decrease. The results of CA Markov analysis show that the built-up area is predicted to continue to increase from 2000 to 2030, meanwhile paddy fields and water bodies will continue to decrease.

El objetivo del presente trabajo fue evaluar los cambios espacio-temporales en el estado de bienestar de sus poblaciones en un tramo de este río, aguas abajo de la represa Yacyretá. Los peces fueron colectados, desde julio de 2009 a junio de 2013, con una batería de redes agalleras en dos sitios seleccionados en relación con su distancia a la represa (Ituzaingó = 1 km aguas abajo; Itá Ibaté = 90 km aguas abajo). Se aplicó un análisis factorial de la covarianza a fin de evaluar el efecto del sexo, sitios y ciclo hidrológico (2009/10, 2010/11, 2011/12, 2012/13) sobre el factor de condición relativo Kn, de los peces. Los resultados mostraron que el factor fue siempre superior en las hembras. Las diferencias entre sitios de muestreo no fueron significativas, aunque se registraron valores de Kn, más elevados en Itá Ibaté. Además, se detectó un efecto significativo del ciclo hidrológico (p < 0,05), con valores de Kn, mayores en ciclos con inundaciones más pronunciadas. Los resultados obtenidos demuestran el fuerte efecto modelador del régimen hidrológico sobre las poblaciones de L. acutidens en este tramo del río Paraná.

Choosing expedition partner has been becoming a crucial issue for those who are running retail business in this digital era. Having the right partner in expedition to work with can be another competitive advantage for the company itself. In this era, almost every transaction would be done online, therefore the meeting between sellers and buyers is no longer necessary in some cases; but still the trust between them must be maintained. Choosing the right expedition is one of the ways to maintain that trust. The right expedition partner here will be defined as those expedition company who can guarantee to deliver product faster (on schedule), cheaper for the service price and also easy to be contacted. Tanah Abang itself is the biggest market in Jakarta. This place has been chosen as the object for the research because the sellers here are actively selling product both offline and online. Descriptive approach has been used for the research methodology. Data are generated from questionnaire and interview. All data that have been gathered will show the number of seller or trader who is actively purchase expedition services in a week. Besides that, it is cleared seen which and why such expedition company leading the market.

Achieving dexterous manipulation for minimally invasive surgical robots through the use of hydraulics
Authors: Berg Devin R. , Li Perry Y. , Erdman Arthur G.
Published: September 2018

Existing robotic surgical platforms face limitations which include the balance between the scale of the robot and its capability in terms of range of motion, load capacity, and tool manipulation. These limitations can be overcome by taking advantage of fluid power as an enabling technology with its inherent power density and controllability. As a proof-of-concept for this approach, we are pursuing the design of a novel, dexterous robotic surgical tool targeted towards transgastric natural orifice surgery.The design for this hydraulic surgical platform and the corresponding analysis are presented to demonstrate the theoretical system performance in terms of tool positioning and input requirements. The design involves a combination of a novel 3D valve, hydraulic artificial muscles, and multi-segmented flexible manipulator arms that fit in the lumen of an endoscope. A dynamic model of the system is created. Numerical simulations show that a hydraulic endoscopic surgical robot can produce the desired performance without using large external manipulators such as those employed by conventional surgical robots. They also provide insight into the component interactions and input response of the system. Future work will include manufacturing a prototype to validate the concept and the numerical models.
Fisheries bycatch risk to marine megafauna is intensified in Lagrangian Coherent Structures
Authors: Scales Kylie , Hazen Elliott , Jacox Michael , Castruccio Frederic , Maxwell Sara , Lewison Rebecca , Bograd Steven
Published: September 2018

Incidental catch of nontarget species (bycatch) is a major barrier to ecological and economic sustainability in marine capture fisheries. Key to mitigating bycatch is an understanding of the habitat requirements of target and nontarget species and the influence of heterogeneity and variability in the dynamic marine environment. While patterns of overlap among marine capture fisheries and habitats of a taxonomically diverse range of marine vertebrates have been reported, a mechanistic understanding of the real-time physical drivers of bycatch events is lacking. Moving from describing patterns toward understanding processes, we apply a Lagrangian analysis to a high-resolution ocean model output to elucidate the fundamental mechanisms that drive fisheries interactions. We find that the likelihood of marine megafauna bycatch is intensified in attracting Lagrangian coherent structures associated with submesoscale and mesoscale filaments, fronts, and eddies. These results highlight how the real-time tracking of dynamic structures in the oceans can support fisheries sustainability and advance ecosystem-based management.

It is often mentioned that the "Silk Road" was a trade route between theEast and the West. Conceptually, it represents the history of communicationbetween China and the West: goods and merchants frequently travelledalong this route. The meaning of the Silk Road and its formation processand scope of influence has been documented in different records, and hadan impact on academic research in several countries: in the field of researchon the history of China, the study of the Silk Road is a subject that manyresearchers have tackled and discussed. Early historical chronicles have beenanalyzed and discussed as well as documents and unearthed artefacts foundalong the Silk Road; these studies involve political, cultural, and economicaspects. Research has not been limited to China, but has also interested thecountries which were along the Silk Road and those which were affected bythe Silk Road culture. The Silk Road acted as a cultural bridge between Eastand West: it did not only promote commerce but also cultural exchanges.For example, Buddhism, as one of the religions of the Kushan kingdom,reached China thanks to this route.

A hotel front desk reservationist is required to communicate using the correct and standard English when serving guests who make hotel reservations. Reservationists who accept hotel room bookings by phone, usually start the conversation using the standard greeting. As a reservationist, the understanding of hotel products should really be considered, such as the location of the rooms, the types of rooms available, the applicable room rates and other service facilities available at the hotel.

Wert-Abjektion als grundlegende Herrschaftsform des patriarchalen Kapitalismus – ‘Sorge(n)freie’ Gesellschaft als Resultat
Authors: Müller Beatrice
Published: September 2018

The article delivers a contribution to theorise (the devaluation of ) care-work in patriarchal capitalism and to connect the theorization with the empirical analysis of the German ambulant care sector in neoliberal times. The central theorem of ‘value-abjection’ transforms Marxist value theory and conceptualizes the abjection of care work as constitutive mechanism of domination in patriarchal capitalism. Transferred to a concrete level of argumentation the theoretical perspective of value-abjection helps not only to analyse the structural tendency of abjection of care work. It also enables to identify empirically- concrete which specific aspects of care and for what reason are structured as abject.

Vom freien Internet zur postdigitalen Gesellschaft
Authors: Ganz Kathrin
Published: September 2018

For the last ten years, the political discourse of Germany’s Digital Rights Movement has centered around a highly idealistic notion of a “free internet”, whereas questions regarding societal relations of production that shape digital economies have been neglected. Recent developments in the field of internet policy and digital rights show that the internet is subjected to capital interests which have been underestimated by the movement. However, the movement is capable to develop a perspective of transformation, stemming from activists’ social practice that is characterized by commons-based production.
Dementia in a regional hospital setting: contextual challenges and barriers to effective care
Authors: Annear Michael J. , Lucas Peter
Published: September 2018

Dementia is a growing public health problem, which may be under-recognised and poorly managed in regional hospitals. With projections of increasing dementia among older adults in regional and rural areas, knowledge about dementia and capacity of professionals to provide best-evidence care is paramount. This research investigates the challenges of dementia care in a publicly funded regional hospital in Australia. The study elucidates prevalence of dementia-related admissions, costs of treatment, length of stay and capacity for dementia care. A mixed methodology was employed in this study, including analysis of hospital records (N = 2405), dementia knowledge surveys (n = 50) and semi-structured interviews with clinical staff (n = 13). Hospital records showed that dementia-related admissions were lower than population prevalence reported in regional Australia. Dementia patients, however, attracted significantly higher treatment costs and greater length of stay than age-matched admissions who did not have a diagnosis of dementia. Clinicians reported several obstacles to effective dementia care, including staff knowledge deficits, environmental challenges, resource constraints and organisational factors.

In the last decades, an effort has been made to improve the efficiency of high-level and academic education players. Nowadays, students’ preferences and habits are continuously evolving and so the educational institutions deal with important challenges, such as not losing attractiveness or preventing early abandonment during the programs. In many countries, some important universities are public, and so they receive national grants that are based on a variety of factors, on which the teaching efficiency has a great impact. This contribution presents a method to improve students commitment during traditional lessons and laboratory tests. The idea consists in planning some activities according to the students’ learning preferences, which were studied by means of two different approaches. The first one was based on Gardner’s multiple intelligence inventory, which is useful to highlight some peculiar characteristics of the students on the specific educational field. In the second method, direct interviews, voice recognition, and text mining were used to extract some interesting characteristics of the group of students who participated in the projects. The methods were applied in May 2018 to the students attending the course of Micro-Nano Sensors and Actuators for the postgraduate academic program dedicated to Industrial Nanotechnologies Engineering of the University of Rome La Sapienza. The present paper represents the first part of the investigation and it is dedicated essentially to the adopted methods. The second part of the work is presented in the companion paper dedicated to the presentation of the practical project that the students completed before the exam.

Published: September 2018

This study analyzes customers’ online social communication to rate lodgings and tourist destinations. A practical methodology is proposed to analyze the online reputation of lodgings as well as the main concepts rated by customers in their online social communication process. To this end, an empirical study was carried out by analyzing the online opinions expressed by customers on the Booking.com tourist lodging website. Based on the information available, three new variables were created and analyzed that represent clearly defined concepts in the minds of consumers. This includes “service quality,” “perceived value,” and “added value.” This study shows that perceived value and service quality are concepts evaluated by customers that are able to differentiate between lodgings in tourist destinations. Therefore, the results show that the online social communication that takes place through this portal has the capacity to guide potential customers by differentiating between the services offered by lodging companies.

Chinese Paocai is a traditional fermented food containing an abundance of beneficial microorganisms. In this study, the microorganisms in Szechwan Paocai were isolated and identified, and a strain of lactic acid bacteria (Lactobacillus plantarum CQPC10, LP-CQPC10) was found to exert an inhibitory effect on constipation. Microorganisms were isolated and identified via 16S rDNA. Activated carbon was used to induce constipation in a mouse model and the inhibitory effect of LP-CQPC10 on this induced constipation was investigated via both pathological sections and qPCR (quantitative polymerase chain reaction). A strain of Lactobacillus plantarum was identified and named LP-CQPC10. The obtained results showed that, as compared to the control group, LP-CQPC10 significantly inhibited the amount, weight, and water content of faeces. The defecation time of the first tarry stool was significantly shorter in LP-CQPC10 groups than in the control group. The activated carbon progradation rate was significantly higher when compared to the control group and the effectiveness was improved. LP-CQPC10 increased the serum levels of MTL (motilin), Gas (gastrin), ET (endothelin), AchE (acetylcholinesterase), SP (substance P), and VIP (vasoactive intestinal peptide), while decreasing the SS (somatostatin) level. Furthermore, it improved the GSH (glutathione) level and decreased the MPO (myeloperoxidase), MDA (malondialdehyde), and NO (nitric oxide) levels. The results of qPCR indicated that LP-CQPC10 significantly up-regulated the mRNA expression levels of c-Kit, SCF (stem cell factor), GDNF (glial cell-derived neurotrophic factor), eNOS (endothelial nitric oxide synthase), nNOS (neuronal nitric oxide synthase), and AQP3 (aquaporin-3), while down-regulating the expression levels of TRPV1 (transient receptor potential cation channel subfamily V member 1), iNOS (inducible nitric oxide synthase), and AQP9 (aquaporin-9). LP-CQPC10 showed a good inhibitory effect on experimentally induced constipation, and the obtained effectiveness is superior to that of Lactobacillus bulgaricus, indicating the better probiotic potential of this strain.
