Resources Allocation to Suppress the Spread of the Epidemic: A New Model with Consideration of Regional Influence (Preprint)
Authors: Yao Gang , Liu Yong , Li Gang , Zhang Xiaoxiang , Wang Liang
Published: November 2021

BACKGROUND

During epidemics, how to allocate resources to suppress the spread of infectious disease is of great significance. Many researches focused on how to suppress the spread of infectious disease in the contact network. However, obtaining the contact network in a short period of time is difficult.

OBJECTIVE

When resources cannot meet the needs of multiple regions, it is necessary to consider how to allocate resources among multiple regions to limit the spread of the disease without details of the contact network.

METHODS

It proposed a resources allocation model to measure the cost of different allocation methods by the number of new infected individuals over a period of time. By calculating the probability of a susceptible individual being infected, it estimated the number of new infected individuals. In order to calculate the probability of a susceptible individual being infected by an infected individual in another region, conditional mutual information was introduced to estimate the strength of association relationship between regions.

RESULTS

Based on the proposed model, it compared the model costs of four different resources allocation methods and found three factors that affect the performance of each method, including the percentage of infected individuals, the resource coverage percentage, and the distribution of infected individuals in each region.

CONCLUSIONS

No method is better than other methods under any situations. When resources are allocated, the method with the least cost in a short period of time should be adopted according to the current infections, so as to control the epidemic as soon as possible.
Correction: Feasibility of Virtual Reality Audiological Testing: Prospective Study (Preprint)

Published: November 2021

UNSTRUCTURED

It has been noted in the literature that there is a gap between clinical assessment and real-world performance. Real-world conversations entail visual and audio information, yet there are not any audiological assessment tools that include visual information. Virtual reality (VR) technology has been applied to various areas, including audiology. However, the use of VR in speech-in-noise perception has not yet been investigated. The purpose of this study was to investigate the impact of virtual space (VS) on speech performance and its feasibility to be used as a speech test instrument. We hypothesized that individuals’ ability to recognize speech would improve when visual cues were provided. A total of 30 individuals with normal hearing and 25 individuals with hearing loss completed pure-tone audiometry and the Korean version of the Hearing in Noise Test (K-HINT) under three conditions—conventional K-HINT (cK-HINT), VS on PC (VSPC), and VS head-mounted display (VSHMD)—at –10 dB, –5 dB, 0 dB, and +5 dB signal-to-noise ratios (SNRs). Participants listened to target speech and repeated it back to the tester for all conditions. Hearing aid users in the hearing loss group completed testing under unaided and aided conditions. A questionnaire was administered after testing to gather subjective opinions on the headset, the VSHMD condition, and test preference. Provision of visual information had a significant impact on speech performance between the normal hearing and hearing impaired groups. The Mann-Whitney U test showed statistical significance (P<.05) between the two groups under all test conditions. Hearing aid use led to better integration of audio and visual cues. Statistical significance through the Mann-Whitney U test was observed for –5 dB (P=.04) and 0 dB (P=.02) SNRs under the cK-HINT condition, as well as for –10 dB (P=.007) and 0 dB (P=.04) SNRs under the VSPC condition, between hearing aid and non–hearing aid users. Participants reported positive responses across almost all items on the questionnaire except for the weight of the headset. Participants preferred a test method with visual imagery, but found the headset to be heavy. Findings are in line with previous literature that showed that visual cues were beneficial for communication. This is the first study to include hearing aid users with a more naturalistic stimulus and a relatively simple test environment, suggesting the feasibility of VR audiological testing in clinical practice.
Using the Technology Acceptance Model to Characterize Barriers and Opportunities of Telemedicine in Rural Populations: Survey and Interview Study (Preprint)
Authors: Holtz Bree , Mitchell Katharine , Hirko Kelly , Ford Sabrina
Published: November 2021

BACKGROUND

Health care access issues have long plagued rural Americans. One approach to alleviating the challenges and poor health outcomes for rural individuals is through the use of telemedicine, sometimes called telehealth. It is important to understand factors that may be related to telemedicine adoption or nonadoption, particularly in underserved rural settings.

OBJECTIVE

This pilot study examines telemedicine perceptions among rural, underserved populations using the Technology Acceptance Model, which serves as a framework to explore the adoption of telemedicine services by those who have used it. This study also explores the differences between user and nonuser perceptions of telemedicine.

METHODS

Paper surveys and phone interviews were conducted in rural Northern Lower Michigan.

RESULTS

Perceived usefulness and perceived ease of use explained 91% of the variability in attitude toward telemedicine (R2=0.91; F1,15=73.406; P<.001). Ease of use was a significant predictor (mean 2.36, SD 1.20; P<.001), but usefulness (mean 3.16, SD 0.81; P=.20) was not. Furthermore, there were significant differences in individual perception of telemedicine between users and nonusers. For example, nonusers believed they would receive better care in person (users: mean 3.30, SD 1.22; nonusers: mean 1.91, SD 1.14; F1,32=10.126; P=.003). The quantitative findings were reinforced by the qualitative results from the phone interviews.

CONCLUSIONS

Overall, the Technology Acceptance Model is an appropriate model to understand the attitudes toward telemedicine that may lead to its adoption by rural Americans.
An Analysis of the Construction of the Multiple Spaces in The Scarlet Letter
Authors: Pan Xingwen
Published: November 2021

Nathaniel Hawthorne, one of the classic writers of American romanticism, wrote many classic works throughout his life, including The Scarlet Letter, the representative of romantic novels and his outstanding masterpiece. Extensive attention has paid on it since it was published. Many literary critics use different theories to explain this work, many of which explore the theme including good and evil, love and hate, and culture under the influence of Puritanism. However, previous researches have paid less attention on the space feature of The Scarlet Letter, and in the traditional narratological research, the space factor has also been ignored for a long time. In this thesis, the author will take space as the starting point based on the relevant spatial theory and spatial narrative research results, and interpret the multiple space construction in The Scarlet Letter in detail, further analyzing the narrative strategy adopted by Hawthorne in order to explore the cultural connotation of the multiple spaces constructed in his works.

Authors: Huang Hui
Published: November 2021

This paper critiques the research article “Exploring the Development of ‘Interest’ in Learning English as a Foreign/Second Language” written by Tan Bee Tin (2013) and mainly analyzes its strengths and weaknesses. Tin (2013) argued that the previous notions for motivation in foreign/ second language learning were considered as inadequate and claimed a new concept from a cognitive perspective. This review paper recognizes the problems Tin (2013) put forward in previous studies on learning interests, but points out that the solutions she described in her research article cannot well fill the gap.

Authors: Tyubee Bernard Tarza , Anyadike Raymond NlemadimChima
Published: November 2021

The study analysed variation in surface temperature (ST) in Makurdi Urban Area (MUA), Northcentral Nigeria. A total of 12 Landsat TM/ETM+ images were acquired in January, April and June of 1991, 1996, 2001 and 2006. The ST was estimated from the 12 Landsat TM/ETM+ images, grouped into seven classes, and the area of each ST class was determined using remote sensing and Geographic Information System (GIS). The ST magnitudes vary spatially from 27.5oC (water bodies) to 50.7oC (built-up land), representing an intensity of 23.2oC. The mean seasonal ST varies from 32.4oC-34.5oC (cool-dry season), 35.5oC-38.8oC (hot-dry season) and 30.8oC-31.4oC (hot-wet season). The mean annual ST has increased from 32.9oC (1991) to 35.9oC (2006) with ST intensity of 3.0oC. The ST classes of 27oC-29oC and 33oC-37oC recorded the highest loss and gain in area of -126.5km2 and 94.5km2 whereas ST classes of 29oC-33oC and 41oC-45oC recorded the least and highest per centage change in area of 22% and 768%. The result showed decreasing and increasing trends in the areas of cooler and warmer surfaces, which are attributed to increase in anthropogen surface materials, with higher heat storage capacities, due to urbanisation.

Authors: Patel Sonu
Published: November 2021

Abstract: Being an eco-friendly system and a cheaper way to produce cooling effect absorption refrigeration system (ARS) is becoming more popular as it can produce higher cooling capacity than vapor compression refrigeration systems, and it can be powered by other sources of energy (like waste heat from gas and steam turbines, or can utilizes renewable source of heat by sun, geothermal, biomass) other than electricity. In the recent years, the interest in absorption refrigeration system is growing because these systems have environmentally friendly refrigerant and absorbent pairs. In this study, a detail energetic analysis of triple stage LiBr-H20 absorption system using First law of thermodynamics is done. An Energy Equation Solver code are used to simulate the computer program is developed for the cycle and results are validated with past studies available is also done. Mass, energy and exergy balance equations and the various complementary relations constitute the simulation model of the triple effect refrigeration system. Further, the effect of exit temperature of generator, absorber, condenser and evaporator on COP, solution concentration and other parameters are studied. It was found in the study that COP increases with increasing the generator exit temperature keeping the absorber exit temperature constant but when the absorber exit temperature is increased COP tends to decrease and the concentration of weak solution leaving HP generator (Xw3), MP generator (Xw2) and LP generator (Xw1) also increases with increase in generator exit temperature, while it decreases with increase in condenser exit temperature. Keywords: Absorption Refrigeration System (ARS), LiBr + H2O, COP, solution concentration, Energy Equation Solver code, energetic analysis, triple effect refrigeration system.
Shopping mall vs Online Retail- Consumer shopping preference in the city of Bengaluru
Authors: Sahay Neha
Published: November 2021

Abstract: Ever since the first fully enclosed and climate controlled mall opened in the United States in 1956 It has caught the fancy of consumers. It revolutionized the way retail was looked at. With everything available under one roof, customers thronged the air-conditioned environments to shop in comfort. Slowly they evolved into a recreation space, with multiplex, food courts, gaming zones which ensured that there was something for everyone in a mall. The replicas were erected all across the world, and embraced with much gusto, as malls became the symbol of urbanization and aspirations for developing nations. In the last two decades or so, India has seen a massive boom in no. and size of a shopping mall. It seemed malls are here to stay even though the high value shoppers were decreasing steadily and the only places you could see crowds were the food courts and the multiplexes, or some large lifestyle stores. The mid and smaller size stores renting out exorbitantly priced floor spaces were starting to wear deserted looks. Then the Covid-19 pandemic hit and forced millions to their homes for months. With shops and malls closed, the online retail exploded and became one of the biggest happening of the last two years. Sitting in comforts of their homes, people were buying food, clothes, electronics, furniture from all over the country, offered to them at an eye watering discount which the physical stores could never match. So has the consumer preference changed in favour of online shopping or malls are still favoured once the lockdown is lifted ?Given the Strong commercial impact that malls have had on Indian retail economy, an attempt was made to understand shopping preference of the consumers in the city of Bengaluru through a questionnaire survey collecting 120 responses. The analysis revealed that consumers still prefer offline shopping for clothes, shoes and accessories. While online shopping is preferred for household items. Groceries, Beauty & cosmetics, Electronics were equally preferred through online or offline mode. Participants were also inclined towards having more open public spaces and sports related facilities in the mall indicating that in Bengaluru malls are also places to socialise and spend quality time together rather than mere shopping spaces.

Published: November 2021

This article highlights an idea of the importance of creativity and innovation in the face of a change that will inevitably occur in global competition, where technological sophistication is the main prerequisite to lead. The research relies on secondary data primarily from books, journals, published reports, online news, and others. This study observes business giants like Google as the best example of maximizing creativity and innovation in global competition and kitabisa.com as Indonesia's local social entrepreneurship pioneer. Then Nokia and Yahoo are examples of failure to implement creativity and innovation. From many theories, there are four theories to draw the relationship among creativity, innovation, and technology, namely: technology S-curve, punctuated equilibrium, dominant design, and absorptive capacity. However, many theories of creativity and innovation developed by scientists have their advantages and disadvantages. This study is expected to provide new insight for individuals, groups, practitioners, or stakeholders to overcome industrial revolution challenges.

Microcrystalline cellulose effects on the rheology of mixed oleogels structured with candelilla wax and saturated fat
Authors: Pérez-Meza Luz , Ruiz-Cabrera Miguel , Morales-Rueda Juan , Pérez-Martínez Jaime
Published: November 2021

The structuration processes of mixed oleogels produced with candelilla
wax (CW, 0 or 3%), fully hydrogenated soybean oil (FH, 5-15%), and
microcrystalline cellulose (MC, 0-9%) were studied to define their
rheological effects. During the cooling CW crystals performed as
nucleation sites for FH. The elastic modulus (G’) of oleogels with FH
and 3% CW were more than two orders of magnitude higher than those
produced with 0% CW. Adding MC to the oleogels increased slightly the
G’. Independently of the amount of MC, oleogels structured with
increasing amounts of FH and 0% CW showed the elastic properties
scaling of colloidal gels. This behavior was lost by adding 3% CW,
implying that in mixed FH-CW oleogels, the CW crystal network dominated
the oleogel rheology. The flow point and the mechanical reversibility of
oleogels and commercial butter (CB) was also determined. CB showed flow
points at 44 and 59% strain and mechanical reversibility values of 29
and 35% of G’ measured in a pre-shear step. Adding MC to oleogels
structured with FH and 0% CW increased their flow point (37.2%) near
those of CB. This effect was not produced in mixed FH-3% CW oleogels.
The mechanical recovery of oleogels produced with FH, MC, and 0% CW
tend to decrease as the FH content increased. CW and MC did not show a
simple concentration–effect relationship for the mechanical recovery.
Nonetheless, oleogels structured with 3% CW and 10% FH and 6-9% MC
showed mechanical recovery (~60%) close to that of CB.
Utmarksetikk i endring?
Authors: Thorseth May
Published: November 2021

Established ethical norms and standards are challenged by the changed use of the outfields (utmark). This chapter undertakes some basic ethical reflections of sustainable governance, strong sustainability and intergenerational justice with respect to the outfields. Basic assumptions about the quality of the outfields are presented. Most importantly, it is argued that sustainability should take its point of departure in a concept of strong sustainability, which implies that the outfields should be conceived of as commons rather than commodities. A critique with a Lockean, liberal understanding of natural resources is put forth, aimed at showing why an individual and anthropocentric framework is insufficient for true sustainable governance. The main reason for this is that nature and natural resources embed values that are complementary to, but not interchangeable with, economic values. A couple of examples of contested commons are presented, in order to demonstrate why commons rich in natural resources must be governed as global property. Fundamentally, this is due to intergenerational justice, which has received worldwide support ever since the UN report Our Common Future was published in 1987.
Fritidsbygg i fjellområdet – en egen boligstruktur?
Authors: Arnesen Tor , Kvamme Stine
Published: November 2021

There are as many leisure and second homes in the mountainous region of Southern Norway as there are primary detached house residences, and since 2000, more than three second homes have been built for every detached house. The balance in housing stock between primary and second homes is rapidly shifting towards secondary homes. More than half of the second homes in the region, and practically all those built since 2000, have high technical standards (water, sewage, road access, Internet service, electricity, etc). On average they are used 60 to 90 days a year (chiefly weekends and holidays), with frequency depending on their technical standard.

A recent demographic report reveals a declining and aging fixed population in the region and forecasts a continuing decline. Second homes in the region are mainly owned by those living in urban coastal areas outside the region, persons who are “invisible” in the local population analysis.

A good half of all second homes, particularly the high-standard ones, are in agglomerations in outlying areas, forming a “recreational sprawl” where urban and rural residences are linked by “recreational commuting”. Covid-19 experiences, with widespread remote working from the second home, has also shown the elasticity between the two residential platforms.

More than just a leisure home, the second home agglomerations may be viewed more accurately as a unique housing stock being developed in mountain areas for part-time rural community inhabitants. A new demographic approach will be necessary to monitor this aspect of the population in many modern rural societies.
Thermo-mechanical fatigue crack growth behaviour of Ti-6246
Authors:   , Palmer Jennie
Published: November 2021

Within the gas turbine engine, the high transient thermal stresses developed due to variations in power requirements during a typical flight cycle give rise to the phenomenon of thermo-mechanical fatigue (TMF). Associated with higher operating temperatures, the study of TMF within the gas turbine engine has mainly been focused on materials used in the latter turbine sections. However, the increasing temperatures to improve operating efficiency have led to the requirements for an understanding of the TMF behaviour in materials used for the later stages of the compressor. As such, fatigue crack growth rates are required to be evaluated under non-isothermal conditions along with the development of a detailed understanding of related failure mechanisms. In the current study a bespoke TMF crack growth (TMFCG) test set up has been developed and validated to investigate the TMFCG behaviour of the titanium alloy, Ti-6246. The study has explored the effects of phasing between mechanical loading and temperature, as well as the effects of maximum cycle temperature. Results show in-phase (IP) test conditions to have faster crack growth rates than out-of-phase (OP) test conditions, due to increased temperature at peak stress and therefore increased time-dependent crack growth. Fractography evidences subtle differences in fracture mechanisms and the microstructural analysis along the crack path has aided the characterisation of damage mechanisms in IP and OP test conditions.
Small Scale testing of Nickel-based Superalloys produced by ALM
Authors:   , Hilal Hani
Published: November 2021

Nickel-based superalloys exhibit an impressive range of mechanical properties, from high temperature strength and toughness to excellent oxidation and corrosion resistance. It is for these reasons that they are heavily incorporated in a wide range of industrial sectors, particularly the aerospace industry where they are extensively utilised within the combustor and turbine section of a holistic gas turbine engine, where temperatures often reach arduous conditions. Although nickel-based superalloys are typically manufactured using traditional cast and wrought methodologies, the aerospace industry is becoming increasingly interested in the use of alternative manufacturing methods in an attempt to further drive gas turbine development through weight reduction and increased Turbine Entry Temperatures (TET). As such, interest regarding the use of near-net shape manufacturing technologies such as Additive Layer Manufacturing (ALM) has risen in parallel, but concerns have arisen given the metallurgical complexity of the process and the prevalence of phenomena such as anisotropic behaviour, residual stressing and structural integrity. This thesis has investigated the influence of key process parameters and variables on the mechanical and microstructural behaviour of the two-contrasting nickel-based superalloys, CM247LC and IN718. A novel miniaturised mechanical testing method, Small Punch (SP), in combination with in-depth material characterisation techniques was implemented on a series of Laser Powder Bed Fusion (LPBF) variants of differing build orientation and parameter selections. In addition to this, a robust analytical methodology was employed on a series of LPBF variants in order to ascertain process parameters’ influence on melt pool profile and both alloys relative propensity for defect formation. The findings of this work will help further the understanding of parameter selection and support a key development strategy being implemented by Rolls-Royce plc. regarding the safe incorporation of additive components into service.

Published: November 2021

В последнее десятилетие важное значение в исследованиях по стратегическому и инновационному менеджменту приобрела концепция инновационных экосистем. Появление Интернета вещей негативно отражается на разных отраслях экономики. Даже традиционные отрасли, такие как топливно-энергетический комплекс, находятся под давлением необходимости развивать экосистемы и управлять ими в ходе своих НИОКР. Акторно-сетевая теория является наиболее целесообразным инструментом, так как она позволяет исследователям анализировать, как акторы (субъекты) взаимодействуют друг с другом на основе своих специфических интересов. Данная теория еще больше расширяет перспективу обращения с акторами, так как она включает в себя человеческие и нечеловеческие акторы.

Viral infections continue to cause significant morbidity and mortality worldwide. The association of pathogens often changes not only the typical clinical picture of the infection, but also its course, which often becomes the reason for the delayed diagnosis and lack of adequate treatment. The variety and discovery of new respiratory viruses, their variability, the rapid formation of strains resistant to antiviral agents and modifying adaptive immune responses in humans, lead to an increase in the frequency of mixed viral infections, which dictates the need to develop and implement new diagnostic and treatment algorithms. This review is devoted to the problem of acute viral infections with combined lesions of the respiratory tract and gastrointestinal tract (GIT) among the population of children. The etiological structure of causative agents of acute respiratory infections (ARI), acute intestinal infections (AII) and infections with combined lesions of the respiratory tract and GIT in children is presented. The features of the pathogenesis and clinical features of rotavirus, coronavirus infections are considered. An algorithm for making a decision on the appointment of a treatment-and-prophylactic complex for children with AII and ARI is proposed.
Review on the Techniques Used for Enhancing Performance of UPQC Structures
Authors: Mandal Sikandra Kumar , Singh Nishi
Published: November 2021

In a power transmitting network, a Unified Power Quality Conditioner is used to operate both shunt— connected and series-connected compensation simultaneously. Destabilize, disturbance, and sometimes even dc elements can all be found in a power distribution network. As a result, a UPQC (Unified Power Quality Conditioner) outperforms a Unified Power Flow Conditioner (UPFC) in many of these areas to offer shunt-connected or series-connected compensation. The main objective of this paper is to provide the overview, different designs given by many researchers to improve the performance of the UPQC.

There are multiple resource of energies but if we talk about renewable energy then solar energy is one of the renewable energy which is in demand because it is feasible and cheap.  Flat - plate solar air heaters (SAHs) are simplistic and stylish, and their heating pathway of implementation requires care and support. increasing Room temperature, elimination of moist from farm commodities, increasing temperature of industrialized goods, hardening of wood or timber, and other uses for SAHs are frequent. well there are several issues in SAH, but the biggest issues with the SAH is its ineffectiveness, which is caused by atmosphere's lower heat transferring ability. We present introduces on the work performed by a lot of scientists to boost the effectiveness of solar air heaters (SAHs) with various kinds of roughness area in this research article.

Published: November 2021

Este artigo tem como objetivo analisar as representações sociais que as Mulheres Surdas fazem de si e os efeitos dessas representações na construção de suas identidades e, de maneira específica, ilustrar a concepção de feminismo que as mulheres surdas possuem. A pesquisa é de cunho qualitativo entrelaçada com a Teoria das Representações Sociais, com o foco nas representações que as Mulheres Surdas fazem de si; isto é, na maneira como elaboram e partilham simbologias significantes e construtivas de suas identidades. Por sua vez, as bases teóricas desta pesquisa provêm do campo epistêmico: feminismo, surdez e das representações sociais. As considerações finais ilustram as concepções de Mulheres Surdas sobre o feminismo e as representações sociais sobre suas identidades. Identidade pressuposta, a partir da invisibilidade, exclusão e preconceito que os outros lhes narravam, e identidade metamorfose, com empoderamento, no reconhecimento de suas diferenças e na valorização delas.

Foreign bodies in the anus and rectum are not uncommon presentations globally. Reasons for foreign bodies in the rectum can be trauma, assault, psychiatric reasons but the most common reason documented is sexual pleasure, and objects range from sex toys to tools to packed drugs. Regardless of the reason, health care providers must maintain nonjudgmental composure and express empathy. Numerous cases have been reported of anorectal foreign body due to various causes. Removal of the objects has mostly been through rectally but some does need surgical intervention. A multidisciplinary approach and radiologic investigations are important to guide in the management outline. Establishment of guidelines for anorectal foreign bodies are needed to guide surgeons and emergency physicians on the course of treatment. We present a case of an eleven-year old school boy slid and fell on an iron rod that penetrated his rectum through his anal canal. Presented with clinical features of peritonitis, where emergency laparotomy was done and the iron rod was extracted abdominally with primary repair of the rectum. The boy recovered well and was discharged four days after with no complications.

Background: Leeches are hermaphroditic rare blood-sucking human endoparasitesof phylum Annelida and class Hirudinea. Leech infestation is a zoonotic disease acquired by drinking contaminated water, swimming in ponds and streams .1Epidemiology of leech bites in literature is limited and the majority of existing data are case reports from the tropics or subtropics.2–4 Leech bites can occur on various orifices of the body including internal body cavities and orifices, such as the uterus, rectum, urinary bladder, vulva, nasal cavity, peritoneal cavity, nasopharynx, oropharynx, oesophagus, trachea, bronchi and the vagina.5 Different chemicals for leech removal have been utilized and include anesthetics drugs like lidocaine and topical anesthetic spray. Salt, saline, vinegar, alcohol, and heat are also viable options. Of these, saltwater has been shown to be effective in causing the leech to relax and release.Vaginal bleeding resulting from leech bite is rare, but when it occurs, it may be of severe morbidity.2–4 In the present case report that happened at Kabaya district hospital, a six year old child with vaginal bleeding that turned out to be caused by vaginal leech infestation is presented. Kabaya district hospital is a rural hospital with 144-bed capacity and serves 188,902 inhabitants and is geographically difficult to access due to the lack of reliable roads and bridges, especially in the rainy season.
