Microwave Staring Correlated Imaging Method Based on Steady Radiation Fields Sequence
Authors: Zhang Jianlin , Yuan Bo , Jiang Zheng , Guo Yuanyue , Wang Dongjin
Published: November 2020

Microwave Staring Correlated Imaging (MSCI) is a newly proposed computational high-resolution imaging technique. The imaging performance of MSCI with the existence of modeling errors depends on the properties of the imaging matrix and the relative perturbation error resulted from existing errors. In conventional transient-radiation-fields-based MSCI, which is commonly accomplished by utilizing random frequency-hopping (FH) waveforms, the multiple transmitters should be controlled individually and simultaneously. System complexity and control difficulty are hence increased, and various types of modeling errors are introduced as well. The computation accuracy of radiation fields is heavily worsened by the modeling errors, and the transient effect makes it hard to take direct and high-precision measurements of the radiation fields and calibrate the modeling errors with the measuring result. To simplify the system complexity and reduce error sources, in this paper, steady-radiation-fields-sequence-based MSCI (SRFS-MSCI) method is proposed. The multiple transmitters are excited with coherent signals at the same observation moment, with the signal frequency varying in the whole frequency band during the imaging process. By elaborately designing the array configuration and the amplitude and phase sequences of the coherent transmitters, the SRFS-MSCI is thus implemented. Comparing the system architecture of the proposed SRFS-MSCI with the conventional random FH-based MSCI, it can be found that the proposed method significantly reduces the number of baseband modules and simplifies the system architecture and control logic, which contributes to reducing error sources such as baseband synchronization errors and decreasing deterioration caused by error cascade. To further optimize the design parameters in the proposed SRFS-MSCI system, the Simulated Annealing (SA) algorithm is utilized to optimize the amplitude sequences, the phase sequences, and the antenna positions individually and jointly. Numerical imaging experiments and real-world imaging experiment demonstrate the effectiveness of the proposed SRFS-MSCI method that recognizable high-resolution recovery results are obtained with simplified system structure and optimized system parameters.
A Lightweight Three-Factor Authentication Scheme for WHSN Architecture
Authors: Almuhaideb Abdullah M. , Alqudaihi Kawther S.
Published: November 2020

Wireless Healthcare Sensor Network (WHSN) is a benchmarking technology deployed to levitate the quality of lives for the patients and doctors. WHSN systems must fit IEEE 802.15.6 standard for specific application criteria, unlike some standard criteria that are difficult to meet. Therefore, many security models were suggested to enhance the security of the WHSN and promote system performance. Yu and Park proposed a three-factor authentication scheme based on the smart card, biometric, and password, and their scheme can be easily employed in three-tier WHSN architecture. Furthermore, they claimed that their scheme can withstand guessing attack and provide anonymity, although, after cryptanalysis, we found that their scheme lacks both. Accordingly, we suggested a three-factor authentication scheme with better system confusion due to multiplex parametric features, hash function, and higher key size to increase the security and achieve anonymity for the connected nodes. Moreover, the scheme included initialization, authentication, re-authentication, secure node addition, user revocation, and secure data transmission via blockchain technology. The formal analysis of the scheme was conducted by BAN logic (Burrows Abadi Nadeem) and the simulation was carried out by Tamarin prover to validate that the proposed scheme is resistant to replay, session hijacking, and guessing attacks, plus it provides anonymity, perfect forward secrecy, and authentication along with the key agreement.
Success Probability Characterization of Long-Range in Low-Power Wide Area Networks
Authors: Kim Yi-Kang , Kim Seung-Yeon
Published: November 2020

In low-power wide area networks (LPWAN), a considerable number of end devices (EDs) communicate with the gateway in a certain area, whereas for transmitted data, a low data rate and high latency are allowed. Long-range (LoRa), as one of the LPWAN technologies, considers pure ALOHA and chirp spread spectrum (CSS) in the media access control (MAC) and physical (PHY) layers such that it can improve the energy efficiency while mitigating inter-cell interference (ICI). This paper investigates the system throughput of LoRa networks under the assumption that the interferences between EDs for exclusive regions are ignored using CSS. In order to establish an analytical model for the performance of LoRa, we introduce the pure ALOHA capture model, which is the power threshold model. For this model, we assume that the interfering power is proportional to the length of the time overlapped. In addition, we discuss LoRa gain by comparing the total throughput of LoRa with that of non-CSS.
The Environmental Impact of Consumption Lifestyles: Ethically Minded Consumption vs. Tightwads
Authors: Touchette Laurie , Nepomuceno Marcelo Vinhal
Published: November 2020

This study investigates the environmental impact of anti-consumption lifestyles and compares it to environmental concern and ethically minded consumption. Environmental impact was measured in a sample of 357 individuals with a carbon footprint calculator capturing all greenhouse gases released by an individual’s activities. Three types of anti-consumption lifestyles were considered: frugality, voluntary simplicity, and tightwadism. Results suggest that tightwadism is negatively associated with environmental impact. This negative association is stronger when participants are knowledgeable about the emissions impact of their behaviors. These findings suggest that tightwadism can lead to positive outcomes to achieve sustainability. Surprisingly, frugality and voluntary simplicity, as well as environmental concern, are not significantly associated with environmental impact, whereas ethically minded consumption correlates positively with the latter. This study demonstrates that increasing consumers’ environmental and ethical concerns alone might not be an effective way to lead them towards a more sustainable lifestyle. Such findings have important implications for sustainability and public policy makers.
Analytical Mathematical Modeling of the Thermal Bridge between Reinforced Concrete Wall and Inter-Floor Slab
Authors: Basiricò Tiziana , Cottone Antonio , Enea Daniele
Published: November 2020

The evaluation of thermal bridges in buildings, following the UNI TS 11300-1:2014 standard, must be carried out with finite element analysis or through the use of atlases compliant with the UNI EN ISO 14683:2018. The paper illustrates the development of an analytical tool to determine the internal linear thermal transmission coefficient (ψi) for the thermal bridge between concrete wall and inter-floor slab, neglected in the main existing catalogs or atlases. This type of thermal bridge is relevant in multi-story buildings, and is typical of public housing districts built between the 1960s and 1970s throughout Europe by means of industrialized systems. Considering energy requalification, due to their low energy efficiency, these buildings require adaptation to the standards imposed by law, and this thermal bridge, which has a high percentage incidence on the total heat losses, cannot be overlooked. From the survey of a representative number of such buildings in Italy, three different technological solutions were examined, with dimensional variations in the individual technical elements and the related functional layers. The combination of these variables resulted in 216 different case studies. The analysis of the existing atlases and catalogues has demonstrated their inapplicability for the selected case studies. For each one of these, ψi was calculated, using off-the-shelf software. The correlation of the data made it possible to determine an analytical mathematical modeling process to assess heat losses due to the analyzed thermal bridge. The validity of this mathematical formula was verified by recalculating the typologies investigated, reaching an error evaluated by means of the mean square deviation equal to ±4%.

Published: November 2020

Factors controlling the spatial distribution and temporal trend of groundwater quality at a national scale are important to investigate for sustaining livelihood and ecological balance. This study evaluated groundwater quality data for 12 parameters (n = 6405 for each parameter), collected from 97 groundwater monitoring stations (=289 monitoring wells) for ten years. Spatial distribution of groundwater quality parameters varied through the regional scale. Six parameters: T, EC, Ca2+, Mg2+, HCO3−, and Cl− were having dominant increasing trend, remaining pH, Eh, Na+, K+, SO42−, and NO3− showed a dominant decreasing trend over time. Among land use types, the upland fields had the highest mean of groundwater NO3− (22.2 mg/L), confirming plenty of application of fertilizers (5–10 kg/a more than standard) to upland fields. Means of groundwater Cl− and Na+ (705.3 and 298.4 mg/L, respectively) in the residential areas are greater than those in other land use types by 408–685.9, 154.3–274.2 mg/L, respectively. Agricultural activities were the main controlling factor of groundwater NO3− contamination in rural areas, domestic activities were responsible for groundwater Cl− and Na+ in urban areas, and seawater intrusion was controlling groundwater Cl− in coastal areas (within 10 km from sea). Groundwater hydrochemistry was controlled by the mechanism of geogenic rock and evaporation dominance. The rock dominance mechanism indicated that groundwater was interacting with rocks and resulted in groundwater chemistry. The findings of this study showed that groundwater was mainly contaminated by anthropogenic factors in some rural and residential areas. Effective measures by government authorities are needed to improve the groundwater quality.
Does Haze Drive Pro-Environmental and Energy Conservation Behaviors? Evidence from the Beijing-Tianjin-Hebei Area in China
Authors: Watanabe Reeko , Watanabe Tsunemi
Published: November 2020

Humans conduct themselves in relation to energy use; energy use has degraded air quality, as reflected by haze occurrence in countries such as China. Improving the population’s involvement in environmental and energy conservation necessitates understanding their motivation to behave under haze. Considering the social problems caused by haze conditions in China, this study used people’s risk perception as a basis to determine their motivations to perform pro-environmental and energy-saving behaviors. We analyzed motivation from privately and publicly oriented perspectives as well as adaptive and mitigative behavioral viewpoints. Motivation-related data were collected through face-to-face discussion and a survey of 506 respondents in the Beijing-Tianjin-Hebei area, which is one of the most heavily polluted regions in China. We conducted multiple regression analysis to determine the extent to which socio-demographic characteristics and risk perception concerning haze predict motivation and actual behavior. Results showed that these factors explain 36.8% and 30.5% of privately and publicly oriented motivations, respectively, but more strongly explain more adaptive (i.e., privately oriented; 55.0%) than mitigating (i.e., publicly oriented; 8.8%) behaviors. Although the residents are motivated to behave equally for private and public purposes in initial conservation efforts, they tend to exhibit adaptive behavior more frequently than mitigating behaviors. These results serve as a reference in encouraging China’s residents to act pro-environmentally and use energy conservatively, thereby contributing to environmental and energy saving education for the society.

Published: November 2020

In this study, we investigated the modelling and optimization of drinking water supply system reliability in the village of Zaben, Czech Republic. An in depth overview of the water supply network in the municipality, passport processing and accident and malfunction recording is provided based on data provided by the owner and operator of the water mains as well as the data collected by our own field survey. Using the data processed from accident and failure reports in addition to water main documentation, the water supply network in Zaben was evaluated according to the failure modes and effects analysis methods. Subsequently, individual water supply lines were classified based on their structural condition. In addition, a proposed plan for financing the reconstruction of the water supply mains in Zaben was created. As such, this study provides an overall assessment of the water supply network in Zaben alongside a proposed plan for the structural restoration of the water supply system, which accounts for the theoretical service life of the system and the financial resources of the owner.
College Campuses and Student Walkability: Assessing the Impact of Smartphone Use on Student Perception and Evaluation of Urban Campus Routes
Authors: Lee Joohyun , Shepley Mardelle McCuskey
Published: November 2020

The purpose of this study is to assess the relationships between college campus walking route characteristics and student perceptions of them with smartphone use. The study used student sketch maps, survey questionnaires, and observations and measurements of route features on a Korean urban campus. The results show that the pedestrian perception and evaluation of campus walking routes are impacted differently in two conditions: walking with smartphone use and walking without smartphone use. “Smartphone walkers” found the safety and quality of routes more important, while walkers without phones considered the shortest distance and positive walking experience to be important factors in their route choices. Campus-built environments need to be improved to provide more adaptive solutions to respond to changes in pedestrian behavior and perception due to increased “smartphone walking”. Recommendations include a walker-friendly campus with well-connected streets and networks, separation from vehicles (ensuring safety), good quality sidewalks, and increased campus green space.
The Effects of the Antecedents of “Buy-Online-Pick-Up-In-Store” Service on Consumer’s BOPIS Choice Behaviour
Authors: Kim Kihyung , Han Sang-Lin , Jang Young-Yong , Shin Yun-Chang
Published: November 2020

We studied the effect of the antecedents of the buy-online-pick-up-in-store (BOPIS) service on consumer’s BOPIS choice and shopping behaviour. The convenience of BOPIS benefits retailers and consumers; therefore, we used online surveys of consumers and the unified theory of acceptance and use of technology 2 (UTAUT2) model. The results of the study show that performance expectancy, trust, compatibility with BOPIS shopping, hedonic motivation and social influence affected the behavioural intentions in omni-channel BOPIS. However, price value and effort expectancy were not considered to be important factors in choosing BOPIS shopping. A moderating effect of the different age generations was analysed in the model. The managerial implications and the limitations of the study are also discussed.

Published: November 2020

Today, there is a great need for greener urban freight transportations due to their ever-increasing environmental impact. The planet’s climate has been significantly affected as the temperature is constantly rising and extreme weather events are occurring more and more often. Aiming to reduce the environmental impact of freight transportation in urban areas, an advanced vehicle routing and scheduling system for improving urban freight transportations, has been developed. This paper presents the functionality of the advanced system, while also analyzing its subsystems and demonstrating its use in a case study. The system is provided as an integrated cloud-based software to support the needs of logistics companies, in order to efficiently schedule their deliveries and perform the routing of their vehicles. The utilized multi-objective algorithm produces solutions that minimize either the distribution cost or the environmental emissions or a combination of these parameters. An application of the system is performed for validation purposes, concerning the comparison of the system’s results with corresponding real-life data provided by a medium-sized logistics company. The results of the testing reveal its significant contribution to the reduction of the environmental impact of the company’s distribution services.
Binding of CCCTC-Binding Factor (CTCF) to the Minute Virus of Mice Genome Is Important for Proper Processing of Viral P4-Generated Pre-mRNAs
Authors: Boftsi Maria , Majumder Kinjal , Burger Lisa R. , Pintel David J.
Published: November 2020

Specific chromatin immunoprecipitation of salt-fractionated infected cell extracts has demonstrated that the CCCTC-binding factor (CTCF), a highly conserved, 11-zinc-finger DNA-binding protein with known roles in cellular and viral genome organization and gene expression, specifically binds the genome of Minute Virus of Mice (MVM). Mutations that diminish binding of CTCF to MVM affect processing of the P4-generated pre-mRNAs. These RNAs are spliced less efficiently to generate the R1 mRNA, and definition of the NS2-specific exon upstream of the small intron is reduced, leading to relatively less R2 and the generation of a novel exon-skipped product. These results suggest a model in which CTCF is required for proper engagement of the spliceosome at the MVM small intron and for the first steps of processing of the P4-generated pre-mRNA.

Published: November 2020

Norovirus infections are a leading cause of acute gastroenteritis outbreaks worldwide and across all age groups, with two main genogroups (GI and GII) infecting humans. The aim of our study was to investigate the occurrence of norovirus in saliva samples from individuals involved in outbreaks of acute gastroenteritis in closed and semiclosed institutions, and its relationship with the virus strain, virus shedding in stool, the occurrence of symptoms, age, and the secretor status of the individual. Epidemiological and clinical information was gathered from norovirus outbreaks occurring in Catalonia, Spain during 2017–2018, and stool and saliva samples were collected from affected and exposed resident individuals and workers. A total of 347 saliva specimens from 25 outbreaks were analyzed. Further, 84% of individuals also provided a paired stool sample. For GII infections, norovirus was detected in 17.9% of saliva samples from symptomatic cases and 5.2% of asymptomatic individuals. Positivity in saliva occurred in both secretors and nonsecretors. None of the individuals infected by norovirus GI was positive for the virus in saliva. Saliva positivity did not correlate with any of the studied symptoms but did correlate with age ≥ 65 years old. Individuals who were positive in saliva showed higher levels of virus shedding in stool. Mean viral load in positive saliva was 3.16 ± 1.08 log10 genome copies/mL, and the predominance of encapsidated genomes was confirmed by propidium monoazide (PMA)xx-viability RTqPCR assay. The detection of norovirus in saliva raises the possibility of oral-to-oral norovirus transmission during the symptomatic phase and, although to a lesser extent, even in cases of asymptomatic infections.
Camelid Inoculation with Middle East Respiratory Syndrome Coronavirus: Experimental Models of Reservoir Host Infection
Authors: Adney Danielle R. , Clancy Chad S. , Bowen Richard A. , Munster Vincent J.
Published: November 2020

Within the past two decades, three zoonotic betacoronaviruses have been associated with outbreaks causing severe respiratory disease in humans. Of these, Middle East respiratory s yndrome coronavirus (MERS-CoV) is the only zoonotic coronavirus that is known to consistently result in frequent zoonotic spillover events from the proximate reservoir host—the dromedary camel. A comprehensive understanding of infection in dromedaries is critical to informing public health recommendations and implementing intervention strategies to mitigate spillover events. Experimental models of reservoir disease are absolutely critical in understanding the pathogenesis and transmission, and are key to testing potential dromedary vaccines against MERS-CoV. In this review, we describe experimental infections of dromedary camels as well as additional camelid models used to further understand the camel’s role in MERS-CoV spillover to humans.

Published: November 2020

Bovine coronavirus (BCoV), a major causative pathogen of bovine enteric and respiratory diseases and a zoonotic pathogen transmissible between animals and humans, has led to severe economic losses in numerous countries. BCoV belongs to the genus Betacoronavirus, which is a model of a pathogen that is threatening human health and includes severe acute respiratory syndrome coronavirus (SARS-CoV), SARS-CoV-2, and Middle East respiratory syndrome coronavirus. This study aimed to determine whether photocatalytic material effectively reduces CoVs in the environment. Using the film adhesion method of photocatalytic materials, we assessed its antiviral activity and the effect of visible light irradiation according to methods defined by the International Organization for Standardization. Consequently, photocatalytic material was found to have antiviral activity, reducing the viral loads by 2.7 log TCID50 (tissue culture infective dose 50)/0.1 mL (500 lux), 2.8 log TCID50/0.1 mL (1000 lux), and 2.4 log TCID50/0.1 mL (3000 lux). Hence, this photocatalytic material might be applicable not only to reducing CoVs in the cattle breeding environment but also perhaps in other indoor spaces, such as offices and hospital rooms. To our knowledge, this study is the first to evaluate the antiviral activity of a photocatalytic material against CoV.
Analysis of Spatiotemporal Variability of Corn Yields Using Empirical Orthogonal Functions
Authors: Kim Seongyun , Daughtry Craig , Russ Andrew , Pedrera-Parrilla Aura , Pachepsky Yakov
Published: November 2020

We used empirical orthogonal functions (EOF) to analyze the spatial and temporal patterns of corn (Zea mays L.) yields at three hydrologically-bounded fields with shallow subsurface preferential lateral flow pathways. One field received uniform application of manure, the second field received the uniform applications of the chemical nitrogen fertilizer, and the third field received variable rate applications of the chemical fertilizer. The preferential subsurface flow and storage pathway locations were inferred from the ground penetration radar survey. Six-year monitoring data were analyzed. Statistical distributions of EOFs across fields were approximately symmetrical. Semivariograms of the first EOF differed between fields receiving manure and chemical fertilizer. This EOF accounted for 52 to 56% of the interannual variability of yields, and its values reflected the distance to the subsurface flow and storage pathways. The second and third EOF explained 17 to 20% and 10 to 13% of the interannual variability of yields, respectively. The precision applications of the nitrogen fertilizer minimized corn yield variability associated with subsurface preferential flow patterns. Investigating spatial patterns of yield variability under shallow groundwater flow control can be beneficial for the within-field crop management resource allocation.

La memoria de los materiales
Authors:   , Librandi Nancy Beatriz
Published: November 2020

Esta tesis plantea el abordaje de obra artística contemporánea vinculada por el carácter de sus materiales, objetos en ruinas reeditados en un nuevo contrato narrativo, del que emerge una dinámica nómade en la errancia de los objetos en el tiempo y espacio y en los mecanismos para su selección. El concepto de ruina adoptado no refiere únicamente a lo arquitectónico, sino también a otro tipo de objetualidad ruinosa: las ruinas portables. La ruinología y la estética de las ruinas se desarrollaron a partir del estudio de ruinas arquitectónicas; las categorías construidas pueden ser transferidas al estudio de los nuevos tipos de ruina. Las obras visuales y audiovisuales cuya materialidad se construye a partir de objetos portátiles en ruinas, permiten analizar las operaciones retóricas y procedimientos de composición que pueden ser transpuestos –ya sea in situ, con una materialidad sustituida o a través del transformato- al trabajo artístico con y desde las ruinas arquitectónicas. El análisis de las obras demuestra las condiciones de posibilidad artística de los objetos entrados en estado de ruinación y periferizados. Para el estudio de la génesis de lo ruinoso se toman como caso las narrativas construidas en torno a un templo ruinoso del siglo XIX, el de San Nicolás de Bari en Ambil, La Rioja, Argentina. La ruina cobra voz a partir de la palabra de la comunidad, que permite construirle su memoria. En la perspectiva propuesta, son los sujetos y las comunidades los que prestan su voz a esos materiales narrando desde sus marcas las vinculaciones con los acontecimientos generales, la memoria colectiva y los relatos identitarios. Este recorrido visibiliza la tensión entre el deseo de trascendencia y la preservación del sistema-mundo.

Em um cenário em que a arte se tornou política, uma questão fundamental se impõe: entender o lugar dessa arte política. Para muitos, os espaços apropriados para a instauração da arte, de qualquer arte, continuam sendo as instituições de arte, em especial o museu e suas exposições, apesar das contradições sociais que norteiam suas políticas e ações. Neste estudo, com base nas incisões descoloniais de Walter Mignolo, Anibal Quijano, Eduardo Viveiros de Castro e Pedro Pablo Gómez, buscamos investigar as complexidades envolvidas na construção e na recepção da mostra “A Cor do Brasil”, realizada no Museu de Arte do Rio entre 2016 e 2017, tendo como pano de fundo os processos da descolonialidade.

Published: November 2020

By using synchrotron X-ray diffraction, we investigated the in-plane distribution of preferential glide planes in a metamorphic InGaAs solar cell with a relatively low open-circuit voltage (V
oc) compared to other cells fabricated on the same wafer. The reciprocal-space maps revealed that the low-V
oc cell contains several domains with different preferential glide planes of β dislocations. Since fluctuations of the average β-glide plane have not been observed for high-V
oc cells, the observed inhomogeneous distribution should be related to the V
oc degradation. Understanding preferential glide-plane changes within a cell can help to improve the uniformity of cell properties over the whole wafer.

Determination of the drag coefficient by analysing the trajectory of a football
Authors: Pszota Gábor
Published: November 2020

Two different types of motion were analysed based on video footage using the free software tool named Tracker. One of them involved dropping the football vertically without any spin, the other type was the projectile motion resulted from a goalie punt. The analysis consisted of fitting the time dependence of the coordinates using a sixth order polynomial, then using these functions and other parameters to obtain the drag coefficient as a function of speed and Reynolds number. Similarly to previous works, the drag coefficient showed large differences for the different speeds. The irregularities and asymmetry of the ball also caused the results to be different for the different trials depending on the orientation of the ball, as well as the slight horizontal spin of the ball during its projectile motion. This method can prove to be a useful tool for further studies in a more controlled environment with higher quality new balls.

Published: November 2020

Introduction

Shared decision making is an essential component of a patient-centered healthcare system. Several studies have evaluated patients' perception of shared decision making; however, studies reporting physicians' perception of the shared decision-making process are lacking. The objective of this study was to assess physicians' perspectives on shared decision making with their patients in a tertiary care hospital in Riyadh, Saudi Arabia.

Methods

This is a cross-sectional study, in which we adopted the nine-item physician version of the shared decision-making questionnaire (SDM-Q-Doc) to assess physicians' perception of shared decision making. The questionnaire was distributed online and in hard copy form randomly to our institution's physicians.

Results

We collected a total of 125 responses from various specialties. Means and percentage of agreement were tested, with the highest percentage of agreement ranging from 88% to 96.8%. There were significant differences between the groups regarding age and medical degree. There were no significant differences noted for sex or department.

Conclusion

Our findings suggest that most physicians at our institution have a positive attitude toward the process of sharing medical decisions with their patients.

Authors: Doganay Songul , Budak Ozcan , Ozdemir Ayla Eren
Published: November 2020

Objective: In this study, it was aimed to research the effects of nutrition with different diets on the telomere length of granulosa cells.

Material and Methods: In the study, 21 BALB C female rats (in each group; n = 7) were divided into three groups as the standard diet group (SD), the ketogenic diet group (KD) and the western diet group. The animals in the SD group were fed with standard mouse feed, while the KD and WD groups were fed with specially prepared diets. At the end of the experiment, a controlled superovulation stimulation protocol was applied to both ovaries. Smear preparations were ready for telomere length (GLT) and apoptotic (caspase-3) evaluations from granulosa cells taken from oocytes collected from ovaries. 

Results: There was a negative correlation between GLT and body weight (r = -0.424; p = 0.056). However, this correlate was not statistically significant. At the end of the experiment, body weight was significantly higher in the WD group compared to the KD group (p<0.05). GTL value of KD group was higher compared to WD and SD groups (p = 0.000). There was a significant negative correlation between Caspase 3 activity and GLT (r = -0.594; p = 0.004). Caspase-3 H score was statistically significantly lower in the KD group compared to SD and WD groups (p <0.05).

Conclusion: As a result of the study, it was observed that diet types cause changes in GTL, and there was a negative relationship between ¨body weight and caspase-3 activity¨ and GTL. It has also been observed that low KD prevents cells from undergoing apoptosis by increasing GTL and decreasing caspase 3 activity.
Case Report – Possible Manufacturing Workplace Transmission of COVID-19
Authors: Murphy John H.
Published: November 2020

A COVID-19 cluster was identified in an industrial manufacturing workforce soon after being recalled to the workplace following a furlough period. All cases in the cluster (21/85) were male, worked on one side of the plant, and took breaks and lunch together. All
non-cases worked on the opposite side of the plant and similarly took breaks and lunch together. Review of the timing of return from furlough determined that workplace transmission was possible. However, a high percentage of the cases lived in apartment settings where high neighbourhood incidence rates were observed, whereas that was not the case for non-cases. The investigation illustrates the difficulties of distinguishing potential occupational from community transmission.

You, Me, We: Encountering Art, Autobiography and ‘Potential Space’ in the Present
Authors: Morra Joanne
Published: November 2020

In order to critically interrogate the conditions in which we live, and the world around us, feminists have turned to the complexity of their own experience. As we have learned, the time of autobiography is key to its political function: the occasional is the time of prefatory critical reflection (Nancy K. Miller); the belated is the time of the anecdotal (Jane Gallop); the after-effect is the time of belated surprise (Shoshana Felman). But what of the present moment?
In this article, Morra proposes that the representation of the temporal, spatial, and historical present is a powerful form of critique. Bringing to bear Maria Lassnig’s art practice onto feminist theories of autobiography, Morra suggests that the potential space of the present (D.W. Winnicott) is fundamental to autobiography’s ability to provide us with a form of individual and collective feminist resistance.
Czech mortality patterns: the past, the present, and regional dissimilarities
Authors: Rychtaříková Jitka
Published: November 2020

In the interwar period, life expectancy at birth in the Czech Republic was close to the levels observed in France. After the World War II, three dissimilar stages in the development of life expectancy at birth became apparent in the Czech Republic: 1. between World War II and the mid-1960s characterized by mortality decrease; 2. from the mid-1960s to the mid-1980s, showing the deterioration of the survival rate; and 3) from the mid-1980s or the beginning of the 1990s to the present with a reappearance of a new decline in mortality. The recent improvements in the survival rate have been primarily due to the reduction of mortality from circulatory diseases and at older ages. Significantly diverse cause-of-death profiles were found in the Ostrava, Zlín, Karlovy Vary and the Central Bohemia regions, with similar deviations for both sexes in 1994-1997.
Investigation into the Challenges Facing Planning of Mathematic Programme in Senior Secondary Education in Abuja, Nigeria.

Published: November 2020

The aim of this study is to investigate the challenges facing the planning of mathematics programme in Federal Capital Territory, Nigeria. The study adopted descriptive research survey design. The population of the study comprised ninety (90) respondents. Stratified and systematic sampling technique was used to select the sample population. The study employed the used of questionnaire as instrument for data collection. Two lecturers from Educational Administration and planning from University of Abuja was consulted to validate the questionnaire. Three research questions and two hypotheses were developed for the study. Test-retest reliability was employed for the study. Percentage and Chi-square test was used to test the hypotheses and data collected from the study. The result revealed that there are challenges facing the planning of mathematics programme of senior secondary education and the challenges includes; inadequate data/information to plan, inadequate funding of planning of mathematics programme, poor capacity development of few mathematics planners, inadequate professional mathematics planners ,political instability, corruption and lack of political will to support planning of mathematics education. The study concluded that the implication of the challenges on the implementation mathematics education is poor implementation of the mathematics programme in the senior secondary schools. The study recommends that the government should increase the funding of educational planning in the country especially mathematics education.

Background and aim: External humeral condyle fracture associated with a posteromedial elbow dislocation is a very rare entity, of which there are very few cases published. Our objective is to present a complex case treated in our Hospital, the diagnosis, the treatment we chose, and the follow-up at 9 weeks after the intervention. Clinical case: 5-year-old boy with a posteromedial elbow dislocation associated with an external humeral condyle fracture, which was diagnosed by CT and treated surgically using an anterior approach over the elbow, open reduction, and osteosynthesis with K-wires. Results: clinical and radiological results 9 weeks after the intervention were excellent, presenting a Radiographic consolidation of the fracture and an excellent range of joint mobility. Conclusion: early diagnosis and surgical treatment through open reduction and osteosynthesis of the external condyle is the gold standard on treatment for these injuries, since a bad reduction leads to poor long-term results.

The avascular nature of cartilaginous tissue has historically lead to bad prognosis in osteochondral injuries. One of the possible treatment options of these injuries is the use of scaffolds, being superior to other options that obtain a fibrous cartilage as a result. We have elaborated PLLA and CHT microspheres as a scaffold for the treatment of osteochondral injuries carried out in albine New Zealand rabbits. They were distributed into groups with different proportions of microspheres, having also a control group with untreated injuries. Native cartilage of the contralateral knees was also analysed. Samples were evaluated in order to establish the quality of the cartilage obtained (using de macroscopic ICRS, microscopic ICRS II scales and a histomorphometric study).The groups with microspheres obtained a regeneration cartilage with hyaline characteristics, a good cell distribution and regular surface. The control group resulted in a cartilage with worse organization and an irregular surface.
