Authors: Shao Fang , He Zhiqiang , Zhu Zheng , Wang Xiang , Zhang Jianping , Shan Jinhua , Pan Jiajia , Wang Hui
Published: February 2020

BACKGROUND

The prevalence of infertility in China is high, but the advent of assisted reproduction technology (ART) has greatly eased this situation. Social media, such as WeChat official accounts, have become the preferred tool for ART centers to communicate with patients, but their attention and operational status differ, and the Internet influence of WeChat official accounts is insufficient. In addition, questions about whether Internet influence is consistent with academic influence and whether the Internet can influence patients’ choice of medical treatment to a certain extent have not been explored.

OBJECTIVE

This study aimed to examine the operational status and Internet influence of WeChat official accounts for ART centers and to explore the degree of Internet influence on patients’ choices of medical treatment.

METHODS

We collected information from the WeChat official accounts for ART centers approved by the National Health Commission of the People’s Republic of China and used the technique for order of preference by similarity to ideal solution to build an Internet influence model of the ART centers and obtained a Ranking of Internet Influence on Reproductive Centers (RIIRC) for each center.

RESULTS

We found there were 451 ART centers throughout the country by the end of 2016 and 498 by the end of 2018. The number of medical institutions is quite large, but their distribution is uneven, and their level of medical technical ability is very different. Analysis of the text data of posts of WeChat official accounts showed the ART centers have insufficient awareness of network exposure and publicity, and the RIIRC of some medical institutions was inconsistent with their medical level and academic status.

CONCLUSIONS

ART institutions have varying degrees of emphasis and use of WeChat official accounts in China. They fail to realize that the Internet influence of WeChat may bring them potential patient resources and that Internet influence may affect the future market structure of ART and may also potentially affect academic rankings.
Patients’ Perceptions and Attitudes Regarding the Pre-Anesthesia Clinic (PAC) at the National Guard Hospital in Riyadh, Saudi Arabia: An Exploratory Study (Preprint)
Authors: Tashkandi Ghdeer , Abidi Samina
Published: February 2020

BACKGROUND

Preoperative services and education allow patients to take an active role in their recovery and reduce the risk of post-operative complications. Exploring patients’ perceptions and attitudes regarding pre-anesthesia services and education helps reveal gaps in patients’ uptake of them so that targeted educational interventions can be designed and implemented.

OBJECTIVE

This is an exploratory study aimed at increasing the understanding of patients’ perceptions and concerns about and the adequacy of the pre-anesthesia services and educational content provided to them at the pre-anesthesia clinic (PAC) of the National Guard Hospital (NGH) in Riyadh, Saudi Arabia. The information gathered will be used to design and develop an electronic patient education system that will allow patients to access personalized, evidence-based pre-anesthesia information relevant to their upcoming surgeries.

METHODS

Quantitative research methods are used to collect relevant information from patients using a closed-ended questionnaire. The questionnaire includes items on demographics, patients’ perceptions and concerns regarding anesthesia, and the assessment of pre-anesthesia information adequacy.

RESULTS

Our results showed that 94% of the participants consider the PAC very important, and more than half of the participants (56%) were interested in receiving additional educational information about anesthesia via mobile applications. While 100% of the participants were satisfied with the information and services provided at the clinic, the assessment of this information and service adequacy indicated that participants were not adequately informed about anesthesia. Among the most common anesthesia-related concerns were the inability to wake up after anesthesia, becoming paralyzed after spinal anesthesia, the possibility of staying in the ICU after the surgery and developing back pain.

CONCLUSIONS

This gathered information will be used to design and develop an educational intervention that will deliver evidence-based, personalized and easy to understand educational instructions to patients to better prepare them for their upcoming surgery. The proposed system will overcome the problems of (i) the spread of generalized unrelated educational information and instructions, (ii) patients forgetting or misunderstanding the given instructions, (iii) issues with the accessibility of information, and (iv) a lack of communication and interaction between patients and their anesthetist.
Education and the Determinants of Early School Leaving in Campania
Authors: Grammegna Dott. Annalisa , Giarrizzo Dott. Domenica Ina
Published: February 2020

Skills gaps between people and socio-economic groups persist over time and affect the future of generations.Social change sees the relationship between education as a dynamic process, linked to “life long learning” and equity (Lisbon Commision, 2020) and the concept of human capital.The analysis of such a correlation will be the subject of the study to highlight the reasons for early school leaving and the repercussions on the labour market in some disadvantaged territorial units of reference in Campania (Italy).This regional context is characterized by a higher incidence of poverty, poor school performance and a less favourable condition of young people in the labour market.The examination will focus on the northern suburbs of Naples.
Fresh Beef Quality from Cattle Fed Field Peas During Pasture and Finishing Phases of Production
Authors: Hall Hope , Domenech Katherine , Wilkerson Emery , Ribeiro Felipe , Wilke Karla , MacDonald James , Calkins Chris
Published: February 2020

This study evaluated the use of field peas during two phases of production on fresh beef quality. Cattle (n = 232) were assigned to one of six dietary treatments in a 3x2 factorial design consisting of 3 pasture and 2 finishing supplementations. The pasture phase consisted of 1) no supplement, 2) field peas at 0.5% body weight (BW), or 3) dry-rolled corn supplement at 0.5% BW. The finishing phase consisted of 1) no field peas or 2) field peas at 20% dry-matter basis. Strip loin samples, aged 14 d, were subjected to retail display (RD) for an additional 7 d. Tenderness via Warner-Bratzler shear force (WBSF) and Slice Shear force (SSF), objective (L*, a*, and b*) and subjective color, lipid oxidation (TBARS) and fatty acid composition were evaluated. Dietary treatment had no effect on tenderness. Steak discoloration was low (< 3%). All objective color measurements displayed interactions between pasture and finishing diets (L*, P = 0.0035; a*, P = 0.0189; b*, P < 0.0001) yet no consistent patterns among treatments could be identified. Extended aging periods would be required to visually influence consumer color perception. Beef finished with field peas had slightly greater lipid oxidation than samples from cattle not receiving field peas during finishing (1.56 vs. 1.44 mg malonaldehyde/kg tissue, respectively; P = 0.0541). There was a significant interaction between pasture and finishing treatments for C15:1 (P = 0.0331). Feeding field peas during the pasture phase increased C 18:2 (P = 0.0381) relative to cattle supplemented with corn; cattle without supplement in the pasture phase had intermediate amounts of C18:2. Total saturated, unsaturated, monounsaturated, and polyunsaturated fatty acids (P > 0.05) were unaffected by dietary treatments. Field peas may be used for cattle with minimal negative impact on fresh meat quality.
Value cocreation behavior of customers and companies on the Weibo social media platform
Authors: Zhang Huiqin , Lan Hai , Chen Xudong
Published: February 2020

The Weibo social media platform in China has an important role in the value-generation process between a company and a customer. We investigated the relationship between the service quality provided on a company's Weibo page and the two dimensions of customer value cocreation behavior,
namely, participation and citizenship, as well as the moderating effect of collectivism on this relationship. Participants were 354 active users of Weibo. Our findings confirmed that the service quality provided on a company's Weibo page was critical to the generation of customer value cocreation
behavior. Further, collectivism moderated this relationship, with higher levels of collectivism strengthening the Weibo page service quality and customer value cocreation behavior relationship. In addition, customer citizenship behavior was positively related to customer perceptions of brand
image, whereas customer participation was not. Implications for companies in the Chinese context are discussed.

Published: February 2020

Este artigo advém de pesquisa que visou identificar na literatura fatores de contextos de vulnerabilidade social, que interferem na escola e podem influenciar as oportunidades educacionais nessas localidades. Para tanto, fez-se busca no Scielo, em 2017, sobre o tema. A análise do referencial denotou que há um conjunto de elementos externos e internos à instituição escolar, advindos da vulnerabilidade do território, que influenciam suas atividades administrativas e pedagógicas, como: maior carência de instrumentos promotores de bem-estar social na região; homogeneidade do corpo discente; seleção de alunos e professores; rotatividade de profissionais; formação profissional insuficiente; representação negativa dos alunos; simplificação de conteúdos e menor tempo dedicado às práticas educacionais. Conclui-se que esses elementos interferem e dificultam o desenvolvimento das funções da escola enquanto promotora de conhecimentos e acabam criando ou reforçando desigualdades educacionais.

Humanly Gods or Godly Humans: Representation and Anthropomorphism of Mythical Characters in Amish Tripathi’s Shiva Trilogy
Authors: Basu Aritra
Published: February 2020

This paper attempts to analyse the representation of mythical characters in the three novels by Amish Tripathi, namely The immortals of Meluha, The secret of the Nagas and The oath of the Vayuputras. The protagonist is a human being, Shiva, whose bildungsroman through the trilogy transforms him into a God, but without actually changing any of his physical attributes. Thus, at the level of anthropomorphism, this method of representation sheds light on the humane aspect of the divinity. From a perspective of feminist understanding of disability, the character of Kali would be studied, as an initial outcast to an important character in the last two books. Thus, this paper would conclude that Tripathi attempts at a vision of inclusivity, by his clever techniques of the representation of the disabled and the divine alike.

It was with pleasure that I accepted the invitation to be guest editor of volume 9 of plaNext. This publishing initiative of AESOP Young Academics Network, almost reaching a dozen, has an already remarkable amount of knowledge produced and shared, fulfilling the aim based on the strategic vectors referred by Francesco Lo Piccolo in the editorial of the first volume of plaNext: to make Young Academics’ research products more visible; to bring together young academics from Europe and beyond, sharing new research perspectives, intersecting planning with other academic fields; and to combine open access environment with high quality materials (Lo Piccolo, 2015). This could not be truer when looking to contents of past and present volumes of plaNext, by giving visibility to more peripheral planning and research contexts, crossing perspectives from various disciplines while looking at European planning issues and not only.
Balloons to talk about
Authors: Hotakainen Tiina , Oikarinen Essi
Published: February 2020

Relational approaches to urban development have gained ground in academic literature, highlighting diverse perspectives, such as experience, participation, aesthetics, performativity and affection. However, these practices neglect conversation as a connection between local everyday life and urban development. We argue that as art generally provokes discussion, material art acquires potential to question urban development and thus, act as a conversation mediator in public space. To test the hypothesis, we organised an explorative action research study: a data art installation within the annual ‘Oulu Night of the Arts’ in August 2017. The installation illustrated spatiotemporal analysis of everyday life in Åström Park, Oulu, Northern Finland. The art intervention succeeded in engaging diverse social groups online and on-site, although it proved challenging to evoke focused conversations. The induced discussions bore relevance to everyday realities in the locality. If public discourse on urban environment concentrates solely on municipal urban planning projects and visible new constructions, we risk creating a misconception of them being superior to mundane everyday life. The study suggests that even tentative information without specific objectives, when presented in a public data installation, could prove valuable for urban development discourse.
The School Adaptation Process of Imprisoned Parents’ Children
Authors: Arslan Serhat , Kazan Oğuz Serap
Published: February 2020

Prison experience affects not only the prisoner but also his family (Murray, Farrington and Sekol,
2012). The remaining convicted family children should be seen as “direct” victims of imprisonment,
rather than “secondary” victims (Merchil, cited in Mitrani, 2018). Incarcerated parents and
deterioration of family relationships, poverty, low academic performance, aggression, depression,
guilt and substance abuse, are often confronted with many problems (www.childwelfare.gov). Apart
from the “ Waiting Child ”project, there are no concrete studies carried out for the children of
prisoner parents who are in a disintegrated position in many ways. In this study, it is aimed to
determine the problems experienced by convicted family children during school adaptation as
hidden and neglected victims.
The determinants of economic resilience in rural regions. An examination of the Portuguese case
Authors: Hennebry Barraí
Published: February 2020

This paper examines the factors that contributed to the economic resilience of rural regions in Portugal following the recent crisis. Portugal has for a long time faced the issue of regionalisation. However, rural regions in Portugal are not homogenous. Rural regions in Portugal are very diverse and experience very different economic realities. This paper adds to the growing body of literature on regional resilience by focusing exclusively on rural regions. Using an adaptation of Martin’s (2012) sensitivity index as a measure of resilience and bivariate analysis this paper examines the determinants of resilience in rural regions. In terms of economic structure, the paper interestingly finds that reliance on agriculture was beneficial while innovativeness hindered resilience. As for measures of social capital, the paper presents some contradictory findings. Higher rates of crime had a negative impact on resilience, however higher political participation also had a negative impact.
СОВРЕМЕННЫЕ ПРОБЛЕМЫ ДЕГРАДАЦИИ СУХОСТЕПНЫХ ПОЧВ ДОЛИНЫ МАНЫЧ

Published: February 2020

На базе Научно-экспедиционного стационара «Маныч» ЮНЦ РАН в 2009–2018 гг. проведены исследования по проблеме деградации почв сухой степи в долине Маныч на территории Орловского района Ростовской области (охранная и заповедная зоны Государственного природного заповедника «Ростовский»). Выявлено, что усиление аридизации климата и антропогенной нагрузки в сухой степи приводят к засолению, опустыниванию, пастбищной дигрессии. Для почвенного покрова характерна комплексность, обусловленная микрорельефом, высоким уровнем минерализации грунтовых вод (2-6 г/л) и их близким залеганием к поверхности, составом засоленных почвообразующих пород, а также антропогенном воздействием – распашкой целинных почв, высокой пастбищной нагрузкой, развитием эрозионных процессов в результате уничтожения естественного растительного покрова степи. Почвенные комплексы с высокой долей участия солонцеватых и солончаковатых почв (до 20–50%) составляют 25% исследуемой территории. Выпас в первую очередь влияет на показатели почвы, характеризующие плодородие. При возрастании пастбищной нагрузки почвы подвергаются интенсивному иссушению в связи с изреженностью растительного покрова, а также уплотнением верхних горизонтов (1,37 г/см3) и изменениями в структуре на агрегатном уровне. В почвы пастбищ с сильной нагрузкой низки содержание гумуса (не более 1,5 %) и его запасы (53-68 т/га). На исследованной территории площадь средне деградированных почв составляет 40 %, сильно и очень сильно деградированных – 32 %, слабо деградированных – 18 %, целинных (ненарушенных) – 10 %. Необходимы срочные меры по рационализации использования почв и повышению их плодородия, предотвращению развития деградационных процессов в них, а также по строгому контролю за соблюдением условий оптимальной пастбищной нагрузки.

This paper studies the performance of a proposed desiccant assisted air conditioning system operating under the hot and dry climate conditions of Mosul city, Iraq. The proposed system consists of three stages: indirect/direct evaporative cooler, an enthalpy wheel, and a traditional vapor compression system. The performance of the suggested system is compared with that of the vapor compression system operating at the same conditions. The simulation results showed that an optimum rotational speed of 12.5 rpm is required for the enthalpy wheel to achieve the best system performance. The simulation results also showed the ability of the proposed system to achieve a power consumption saving of 51.03%, in the ventilation mode, and 22.93%, in the mixing mode with a ventilation mixing ratio of 0.4 when compared to the vapor compression system.

The Qaidam Basin is located in the northeastern part of the Qinghai-Tibet Plateau (or Tibetan Plateau). It is the world's highest altitude petroliferous basin (the altitude is usually more than 3000m above sea level). But this basin is more famous for its ‘double complex’ in terms of surface and subsurface structures.

Our study areas, YingXi and YingZhong are located at the southwest of YingXiongling structural belt within the Qaidam basin. From the , we can see the "double complex" structures very clearly. The surface is full of wind erosion mountains . The serious elevation variation proposes huge challenge for seismic data acquisition, statics correction and near surface modeling. Meanwhile the subsurface is thrusted severely . The shallow part is thrusted with detachment faults and mainly comprised of severely deformed fold and Shizgou fault, which is the main fault of the survey. The horizon offset across it is usually quite large up to 2km. The study zone is more than 4000m deep where it is thrusted into imbricate fans with very strong overlying structural disturbing. The structure is cut by several groups of low angle faults. This kind of geological condition may produce quite good traps for oil and gas. Besides the overlying salt layers of the study zone extend to certain range which can be very good seal to prevent the oil and gas from migrating upward along Shizgou fault.

These extremely complex geological situations cause a series of world-class E&P difficulties, such as how to obtain better seismic image, where to drill exploration wells, how to design and drill horizontal development wells with higher success rate, and how to submit OOIP or Reserve to the country for so complex region, etc. But to solve these difficulties, one thing is the key, i.e. the accurate structural delineation. This also the final goal of our work. In this paper we will discuss and show how we reach it by integrated Geophysical & Geological modeling.
A Coupled Multiphase Poromechanics--Damage Mechanics Framework for Fracture Modeling During Injection
Authors: Bubshait Ahmed , Jha Birendra
Published: February 2020

The process of fluid injection in oil reservoir to maintain reservoir pressure is a common practice to increase well productivity and enhance oil recovery. These activities cause a change of natural fractures and permeability in stress-sensitive and brittle rocks. Numerical modeling of the evolution in permeability and stiffness of near-wellbore region is required to capture the effect of coupling between fracture dynamics and poromechanics on fluid flow across the length scales of fractures and the host rock. We present such a numerical framework to model dynamic evolution in rock properties based on a coupled formulation of multiphase flow, rock deformation and fracture-induced damage processes. Our framework can handle complex fracture networks with randomly distributed fractures and can model both length and direction of propagating fractures to accurately capture permeability growth within these formations. A sequential solution is used to solve the three coupled problems: (1) multiphase flow, (2) mechanical deformation, and (3) fracture propagation. An implicit finite volume method is used to solve the multiphase flow problem using the Matlab Reservoir Simulation Toolbox (MRST). Following a one-way coupled scheme, multiphase pressures are used in the solution of the quasi-static mechanical deformation problem using the finite element method. This is followed by the solution of the fracture propagation problem and associated evolution in rock properties using the damage mechanics method. The continuum damage mechanics method allows us to use the change in the state of stress computed by the flow-mechanical solver to model the changes in permeability and elastic properties via the damage tensor. We test the capability and efficiency of our framework during simulation of different waterflood patterns in fractured reservoirs and discuss its usefulness in calculating optimum injection/production rates.
Coupling the Dual-Porosity Theory with a Modified Hoek-Brown Criterion on Wellbore Stability Analysis

This paper presents a derivative work based on a previously published paper. In the previous paper, we presented a modified Hoek-Brown criterion (MHB), compared it with the original Hoek-Brown criterion (HB), and showed the advantanges of the MHB. In this paper, The MHB is further investigated. We show that the MHB captures laboratory measurements that shear strengths of rocks degrade with the increase of the intermediate principal stress when the intermediate principal stress is large enough. This is illustrated by comparing the MHB with various triaxial tests on a variety of rock specimen. The MHB and HB together with the analytical dual-porosity dual-permeability poroelastic wellbore solutions have been implemented in a proprietary computational platform. Two case studies, run by the platform, are presented to show the advantages of the MHB and the analytical solutions in wellbore stability analysis accounting for natural fractures.
Kinetics of Breaking of a Sulfobetaine Viscoelastic Surfactant Gel in the Presence of Model Oils

Viscoelastic surfactant (VES) gels are used for well stimulation. Breakers such as ethylene glycol mono butyl ether, are compounds that reduce viscosity of VES gels, and are required after the stimulation job to prevent formation damage. The focus here was to delineate the steps involved in the breaking of a VES gel in the presence of model oils. It also aimed to determine the effect of increasing aliphatic chain length on the gel breaking rate.

A sulfobetaine VES (40 g/L) was mixed with calcium chloride (600 mM) and three model oils (280 mM) in water. The model oils were n-decane, n-dodecane, and n-hexadecane. The complex viscosity (frequency-dependent viscosity) with time was measured for at most 24 hours at 10 rad.s-1 and strain of 2 % using a rheometer. The rheological experiments were conducted at 50 °C.

The viscosity of the VES/oil mixtures increased with time and reached a maximum. The magnitude of the maximum viscosity was dependent on the oil. In the presence of n-decane and n-dodecane, the maximum viscosity steadily dropped for a few minutes before a sharp drop occurred. The drop continued until the viscosity was close to 1 cp. Meanwhile, n-hexadecane increased the viscosity and steadily dropped for 24 hours. The complex viscosity after 24 hours was > 150 cp. The time it took for the gel to break depended on the type of oil. The breakage time increased in the following order: n-decane<n-dodecane<n-hexadecane.

The paper advances understanding of how VES used for well stimulation in carbonate reservoirs are being broken. The study will facilitate the design of well stimulation jobs that require VES and breakers by providing information on what kind of oils are required for the job, and how much time required for the VES solution to turn into a gel and then break.

This study has been conducted to numerically investigate and visualize the way that the entrained sand follows inside a storage tank at various flow velocities. The specific objectives of the work are to:1- Generate a CFD model for sand settlement in a cylinderical storage tank.2- Analyze the effect of flow and sand characteristics on sand deposition inside the storage tank.3- Recommend the optimum flow conditions at which minimum sand deposition takes place. A model geometry for a vertical cylindrical tank with 30 m diameter and 15 m height was created and meshed. The Discrete phase model (DPM) in Fluent has been used to perform the simulation. Sand Retention Testing data for a Malaysian oil field has been used during the solution phase to simulate sand deposition inside the tank, and then, to investigate the effect of flow characteristics on sand deposition. Sand sizes in the range of 0.01-10000 µm and inlet velocities of 1 m/s and 10 m/s have been considered during the simulation, and sand particles are tracked for each flow velocity. The high inlet velocity (10 m/s) shows high turbulence of the flow, and hence, rapid reverse flow takes place near to the inlet. This reverse flow causes the sand particles to stay afloat in the tank and eventually mass of grouped particles form near the inlet. The low inlet velocity (1 m/s), in contrast, results in higher amount of sands that can reach the tank outlet. The low turbulence behavior at lower velocity decreases the tendency of the entrained sand to float on top of the tank. The sand particles, instead, spread at the bottom of the tank with the ability of the upper layer of sand particles to flow gradually. Eventually, more sand particles can be discharged at the outlet. The simulation results presented in this paper can provide a better understanding on the way that entrained sand particles can deposit in or discharge from a liquid storage tank and it can demonstrate how flow characteristics can affect sand deposition. This can assist in setting supervisory strategies for controlling these flow characteristics to avoid or minimize sand deposition.

Direct numerical simulation at the pore scale on three-dimensional (3D) digital volumes obtained by high-resolution x-ray computed tomography (CT) images is a powerful tool for helping predict petrophysical properties. However, obtaining sufficiently high resolution and large field-of-view 3D CT images that capture multiscale heterogeneities in a single image is often not possible. Thus, methods for integrating and upscaling properties from multiple scales at various resolutions to plug scale are necessary. The methodology and results for upscaling capillary-dominated, two-phase flow in rocks based on multiscale CT images using trends are presented and discussed in this paper.
