Nutritional Status Measurement Instruments for Diabetes: A Systematic Psychometric Review
Authors: Montagut-Martínez Pedro , Pérez-Cruzado David , García-Arenas José Joaquín
Published: August 2020

Background: Diabetes is a serious chronic disease associated with a large number of complications and an increased risk of premature death. A dietary evaluation is of utmost importance for health promotion, disease prevention and individual treatment plans in patients with diabetes. Methods: An exhaustive search was carried out in various databases—Medline, Web of Science, Open Gray Cochrane Library and Consensus-based Standards for the selection of health status Measurement Instruments (COSMIN)—for systematic review of the measurement properties of instruments that evaluate the dietary intake of people with diabetes mellitus type 1 and/or 2 according to COSMIN standards. Results: Seven instruments were identified. There was no instrument measuring nutritional status for which all the psychometric properties were evaluated. The methodological quality for each of the psychometric properties evaluated was ‘inadequate’ or ‘doubtful’ for all instruments. The Food Frequency Questionnaire (FFQ) evaluated the most psychometric characteristics and with a better score in terms of quality of the evidence. Conclusions: Several instruments have been developed for the evaluation of dietary intake in people with diabetes. Evaluation of this construct is very useful, both in clinical practice and in research, requiring new knowledge in this area. The FFQ is the best instrument available to assess dietary intake in people with diabetes.
Beyond Strict Regulations to Achieve Environmental and Economic Health—An Optimal PM2.5 Mitigation Policy for Korea

Published: August 2020

Growing concern about particulate matter (PM2.5) pressures Korea to reduce the health risks associated with its high dependency on fossil fuels. The Korean economy relies heavily on large thermal power plants—a major source of PM2.5 emissions. Although air quality regulations can negatively impact local economies, the Korean government announced two strict air quality mitigation policies in 2019. We develop a regional static computable general equilibrium model to simulate the economic and environmental impacts of these polices under alternative hypothetical scenarios. We separate two regions, Chungcheongnam-do, the most polluted region, and the rest of the country, in our model. As policy options, we introduce a regional development tax and a tradable market for PM emission permits, similar to an air pollution tax and a carbon permits market, respectively. The results show that allowing higher tax rates and a tradable permits market gives the optimal combination, with the PM2.5 emissions reduced by 2.35% without sacrificing economic growth. Since alternative options present, for example, a 0.04% loss of gross domestic product to reduce PM emissions by the same amount, our results here may present a new policy paradigm for managing air pollutants such as PM2.5.

Published: August 2020

This study is intended to explore the associations between nutritional status and molecular biomarkers and the clinical severity of Parkinson’s disease (PD), as well as to examine the differences in related factors between PD patients with normal nutrition and those with at risk for malnutrition. A cross-sectional assessment of 82 consecutive outpatients with PD was conducted using the mini nutritional assessment (MNA), Unified Parkinson’s Disease Rating Scale (UPDRS), and the Hoehn and Yahr scale to determine the nutritional status, the clinical severity of PD, and the stage of the disease. Recordings of blood samples collected after 12 h of overnight fasting were also assessed in terms of serum levels of glycated hemoglobin (HbA1c), blood urea nitrogen (BUN), creatinine, cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), hemoglobin (Hgb), folate, and vitamin B12. All participants were divided into normal nutrition and malnutrition risk groups via the MNA scores to compare the above-mentioned parameters. The results showed that the total MNA score was significantly correlated with some parts of the UPDRS scale (e.g., Sections 1 and 2) and the levels of HbAlc in PD patients and those with risk for malnutrition, with significantly lower weight and body mass index (BMI), and with lower levels of Hgb and HDL. Higher levels of cholesterol were observed in the malnutrition risk group as compared with the normal nutrition group. The findings suggest that the clinical severity of PD is associated with nutritional status. Body weight, BMI, and the levels of Hgb, cholesterol, and HDL could be, at least partially, important biological markers to monitor malnutrition and the progression of the disease.

Published: August 2020

Although stimuli-responsive release systems have attracted great attention in medical applications, there has been no attempt at “precise” deep profile control based on such systems, which is greatly need to improve oil recovery. With this in mind, we provided a facile and simple strategy to prepare stimuli-responsive composite capsules of amphiphilic dendrimers–poly(styrene sulfonic acid) sodium/halloysite nanotubes (HNTs) via layer-by-layer (LbL) self-assembly technique, controlling the release crosslinking agent methenamine under different pH or salinity conditions. The release time of methenamine encapsulated in multilayer shells is about 40 h, which can be prolonged with the introduction of salt or shortened via the addition of acid, which accordingly induces the gelation of polyacrylamide (PAM) solutions, taking from a few hours to a dozen days. This study provided a novel approach for controllable release of chemical agents and controllable crosslinking of deep profiles in many application fields.

Published: August 2020

High energy ball milling is used to make first the quaternary sulfide Cu2ZnSnS4 raw nanopowders from two different precursor systems. The mechanochemical reactions in this step afford cubic pre-kesterite with defunct semiconducting properties and showing no solid-state 65Cu and 119Sn MAS NMR spectra. In the second step, each of the milled raw materials is annealed at 500 and 550 °C under argon to result in tetragonal kesterite nanopowders with the anticipated UV-Vis-determined energy band gap and qualitatively correct NMR characteristics. The magnetic properties of all materials are measured with SQUID magnetometer and confirm the pre-kesterite samples to show typical paramagnetism with a weak ferromagnetic component whereas all the kesterite samples to exhibit only paramagnetism of relatively decreased magnitude. Upon conditioning in ambient air for 3 months, a pronounced increase of paramagnetism is observed in all materials. Correlations between the magnetic and spectroscopic properties of the nanopowders including impact of oxidation are discussed. The magnetic measurements coupled with NMR spectroscopy appear to be indispensable for comprehensive kesterite evaluation.

Published: August 2020

Non-alcoholic steatosis and insulin resistance are critical health problems and cause metabolic complications worldwide. In this study, we investigated the molecular mechanism of Polygonum multiflorum Thunb. (PM) against hepatic lipid accumulation and insulin resistance by using in vitro and in vivo models. PM extract significantly attenuated the accumulation of lipid droplets and hepatic triglyceride in free fatty acid (FFA)-exposed HepG2 cells. PM extract increased the AMPK and ACC phosphorylation and GLUT4 expression, whose levels were downregulated in FFA-exposed cells. PM extract also decreased precursor and mature forms of SREBP-1 in FFA-exposed cells. C57BL/6 mice fed with normal diet (ND) or high-fat diet (HFD) were administered PM extract (100 mg/kg) or vehicle orally for 16 weeks. PM extract attenuated the increases of the epididymal and perirenal fats on HFD feeding. PM extract markedly reduced hepatic lipid accumulation and fasting glucose levels, and improved glucose and insulin sensitivity in HFD-fed mice. HFD-fed mice decreased the AMPK and ACC phosphorylation and GLUT4 expression, and increased precursor and mature forms of SREBP-1; these changes were significantly restored by PM extract. In conclusion, PM extract alleviates non-alcoholic steatosis and insulin resistance through modulating the expression of proteins on lipid metabolism and glucose transport in the liver.

Authors: Venn Bernard J.
Published: August 2020

Fat, protein and carbohydrate are essential macronutrients. Various organisations have made recommendations as to the energy contribution that each of these components makes to our overall diet. The extent of food refining and the ability of food systems to support future populations may also impact on how macronutrients contribute to our diet. In this Special Issue, we are calling for manuscripts from all disciplines to provide a broad-ranging discussion on macronutrients and health from personal, public and planetary perspectives.

Published: August 2020

Neurodegenerative diseases are generally characterized by the presence of neurotoxic amyloid aggregates underlying progressive neuronal death. Since ancient times, natural compounds have been used as curative agents for human health. Amyloid research is constantly looking for safe natural molecules capable of blocking toxic amyloid aggregates’ formation. From the marine environment, seaweeds are recognized as rich reservoirs of molecules with multiple bioactivities, including the anti-amyloidogenic activity. Here, hydroalcoholic extracts of two seasonal samples of the Mediterranean red seaweed Halophytis incurva (HIEs) were characterized by the HPLC-DAD-MS analysis. The H. incurva anti-amyloidogenic role was explored by incubating both HIEs with hen egg white lysozyme (HEWL), a well-known protein model widely used in amyloid aggregation experiments. The aggregation kinetics and morphological analysis of amyloid aggregates were performed by ThT and AFM analysis, respectively, while their cytotoxicity on SH-SY5Y human neuroblastoma cells was examined by MTT assay. HIEs showed a different efficacy, probably dependent on their metabolic composition, both in inhibiting amyloid fibrillation and in obtaining short and less toxic pre-fibrillary aggregates. Overall, this work sheds light, for the first time, on a Mediterranean red seaweed as a promising renewable resource of bioactive compounds, potentially useful in preventing the formation of toxic amyloid aggregates.
Liturgy and Landscape—Re-Activating Christian Funeral Rites through Adaptive Reuse of a Rural Church and Its Surroundings as a Columbarium and Urn Cemetery
Authors: Goyvaerts Samuel , Vande Keere Nikolaas
Published: August 2020

We present the design research for the adaptive reuse of the St. Odulphus church as a columbarium in the village of Booienhoven (BE). Surrounded by agriculture, the site is listed as a historic rural landscape. The small neoclassical church is no longer in use for traditional Catholic services and is abandoned. Positioned on an isolated “island”, it has the appropriate setting to become a place to remember and part from the dead. Instigated by the municipality, and taking into account the growing demand for cremation, we present topological research on three different liturgical and spatial levels: 1/the use of the church interior as a columbarium and for (funeral) celebration, 2/the transformation of the “island”, stressing the idea of “passage” and 3/the layering of the open landscape reactivating the well-spring and its spiritual origins. Based on the reform of the funeral rite after Vatican II, we propose a layered liturgy that can better suit the wide variety of funeral services in Flanders today, while at the same time respecting its Catholic roots. Rather than considering the reuse of the church a spiritual loss, we believe that it can offer the opportunity to reinforce and open up the traditional, symbolic and ritual meaning of the Christian liturgy to the larger community. As such, this case is an excellent example of how, in exploring new architectural and liturgical questions, religious sites can be transformed into contemporary places for spirituality.
Co-opted Directors and Board Effectiveness: The Impact of Director Gender
Authors: Wilson Thomas
Published: August 2020

Independent directors are viewed as critical to effective corporate governance. However Coles et al. (2014) introduce the concept of a “co-opted” director, one appointed after the firm’s CEO took office. They argue that, although technically independent, co-opted directors’ interests are more aligned with the CEO who was instrumental in their selection than with shareholders. However, research has shown that woman directors are more conscientious about their board duties than are men. This study investigates whether director gender mitigates the impact of co-option on board effectiveness, as measured by the frequency of board meetings. The results indicate that an increase in the proportion of co-opted male directors on a board is associated with a less effective board. However, no such relation is found for co-opted female directors. Despite incentives to act otherwise, boards with higher percentages of co-opted women directors appear to continue to fulfill their duties to shareholders.

Reingreso al emprendimiento después del fracaso: Factores que influyen sobre los emprendedores seriales y de segunda oportunidad
Authors: Ibáñez Caamaño María José
Published: August 2020

Este artículo investiga los factores que influyen en la probabilidad de volver a emprender luego del fracaso empresarial, entre estos, los factores sociodemográficos y los económicos. En particular, se examina el efecto de la edad, el nivel educacional, el rol proveedor del emprendedor en la familia, la cobertura de los instrumentos y los servicios públicos para el emprendimiento, así como los motivos que llevan al emprendedor al cierre del negocio, sobre la disposición del emprendedor fallido a iniciar una nueva empresa. Se utiliza una muestra de 274 emprendedores fallidos de Chile, el país con la mayor tasa de actividad emprendedora (TEA) en el mundo, según el reporte del GEM 2019/2020. Los resultados de este estudio señalan que las variables principales tienen una influencia negativa en la probabilidad de reingresar al emprendimiento luego del fracaso empresarial, pero solo resultan significativas la edad, la cobertura regional de los servicios técnicos para el emprendimiento, la quiebra, la preferencia por el trabajo asalariado y el desempleo a nivel regional. Esta investigación contribuye a ampliar la evidencia empírica respecto a los factores que influyen sobre los emprendedores en serie y de segunda oportunidad, más allá de los aspectos relativos a la intención emprendedora y los elementos del comportamiento del emprendedor. Este trabajo entrega conclusiones relevantes orientadas al diseño de políticas públicas e instrumentos de fomento para los emprendedores que están dispuestos a crear un nuevo negocio luego del fracaso empresarial.

It is very obvious that human fall due to unconsciousness is a very common health problem in every human being. With the evolution of many smart health devices, we should contribute the technological advancement of machine learning into it. Different techniques are already used in order to detect human fall detection in human beings. In this paper we have studied the patterns of falling of human through the fall detection dataset while this human was performing various motions. By understanding all these we have generated the prediction protocol which estimates the fall of a person using fall detection dataset. Machine Learning classifiers were used to predict the human fall and a comparative study of various algorithms used was developed to find out the best classifier.

Delamination is a type of defect produced while machining composites or layered materials. Due to matrix crack, shear crack and bending crack delamination is caused. Delamination is usually a separation along a plane parallel to the surface as in the separation of a coating from a substrate or layers of coating from each other. The aim of this project is to explore the study of delamination in carbon Fibre/epoxy composites under abrasive water jet machining. An experimental investigation was held to study the effect of delamination due to abrasive water jet machining on carbon fibre reinforced polymer. Effect of various parameters such as transverse speed, standoff distance, abrasive mass flow rate and water pressure was analysed. Taguchi method was used for overall analysis of parameters. Effect of Kerf width in CFRP material and on fibre cut was analysed step by step. Further observation was done on scanning electron microscopes. It can affect the compression strength of composite laminate and it will slowly cause the composite to experience failure through the buckling. Here the composite of Carbon Fibre Reinforced Polymer is made using carbon fibers and epoxy resin. Further cutting of CFRP is done using Abrasive water jet machining and analysis of delamination at various phases of the material is done. Analysis is done at which parameters delamination is reduced to minimum.

Authors: Battaglia Frank , Sayed Céline , Merlano Maria , McConnell Meghan , Ramnanan Christopher , Rowe Jennifer , Wang Hao , Patel Vishesh , Rastogi Nikhil
Published: August 2020

Introduction: We conducted a national survey to characterize current Canadian procedural skills training in Undergraduate Medical Education (UGME). The goals were to identify the most important procedures students should know upon graduation and assess clinician-educator perceptions regarding implementation of a pre-clerkship procedural program.

Methods: We distributed the survey to physician-educators across Canada’s 17 medical schools. Respondents were directed to an individualized survey that collected demographic data, physician-educator responses on essential procedural skills, as well as physician-educator opinions on the value of a pre-clerkship procedural training program.

Results: The response rate for this survey was 21% (42 out of 201 distributed surveys were completed). The top 10 most important procedures identified by physician-educators included IV Access, Airway Management, Local anesthesia/field block, Casting, Spontaneous Vaginal Delivery, Testing for STIs, Phlebotomy, Suturing of Lacerations, Nasogastric Tube Insertion, and Venipuncture. Physician-educators supported a pre-clerkship procedural program.

Conclusions: Identifying the most crucial procedural skills is the first step in implementing a competency-based procedural skills training program for Canadian medical students. With the list of essential skills, and the support for physician-educators in developing a pre-clerkship procedural skills curriculum, hopefully there can be future development of formalized curricula.
Reliability of cluster head node based upon parametric constraints in underwater acoustic sensor networks

Published: August 2020

Underwater wireless sensor network (UWSN) has emerged as one of the most popular network technologies owing to its applicability to offshore searches, and underwater monitoring and exploration applications. It has been shown to be useful in the fields of investigations and surveillance,
and in assisting with and offering solutions to water-based calamities. Reliability in the underwater environment has caused researchers to direct attention towards improving the overall efficiency and energy utilisation of the network. In the present paper, reliable node quester (RNQ) algorithm
has been formulated to calculate the node reliability for numerous parameters such as success rate, transmission time, and the affordability, congestion and stability of the nodes. The present paper highlights the data-forwarding mechanism of the nodes to enhance overall network reliability
by (i) reducing the packet drop rate; (ii) increasing the packet delivery ratio; and (iii) minimising the energy consumption. Simulation results further support the proposed strategy by ensuring the network lifespan and detection accuracy.

SOME TRENDS IN FRESHWATER TROPICAL AQUACULTURE AND THEIR IMPACT ON STUDIES OF THE CLIMBING PERCH ANABAS TESTUDINEUS (ANABANTIDAE) REPRODUCTIVE BIOLOGY
Authors: Zworykin Dmitry
Published: August 2020

The dynamics of publication activities devoted to the climbing perch from

1969 to 2018 is analyzed. It is shown that sharp increases in the number

of publications at the turn of the millennium coincide with changes in

international and national strategies for tropical fish aquaculture, focusing

on cultivation of fast-growing native fish species and small farms support.

These programs have led to a surge in applied research and publications on

the climbing perch, as one of the most promising species. Unfortunately, some

of these papers have been published in journals that are unreliable according

to the criteria of contemporary science and contain controversial conclusions.

Certain consequences of these trends are noted and challenges outlined.

Razões em três tempos: uma análise comparativa entre três versões do texto “Razões para uma nova arquitetura” de Lucio Costa
Authors: De Pinho Meirelles Christine , M. G. Albano Amora Ana
Published: August 2020

Nossa proposta neste artigo é apresentar e comparar de forma critica as alterações sofridas desde a sua primeira versão do ‘Razões para uma nova arquitetura’, texto que traz pela primeira vez os argumentos nos quais Lucio Costa se baseia para sustentar sua posição em favor de uma nova arquitetura, em duas subsequentes edições. A primeira versão, de 1934, foi publicada na Revista da Diretoria de Engenharia da prefeitura do Distrito Federal, em janeiro de 1936, a intermediária, de 1962, foi publicada em ‘Lúcio Costa: Sobre a Arquitetura’, uma coletânea de textos organizada por Alberto Xavier. Já a última, publicada em 1995, encontra-se no livro ‘Lucio Costa. Registro de uma vivência’.
Reestruturação intraurbana de cidades médias
Authors: Ferretto Diego
Published: August 2020

Este artigo tem por objetivo analisar a disseminação de shopping centers e condomínios fechados de alta renda em cidades médias, a partir dos casos das cidades de Caxias do Sul, Passo Fundo, Pelotas e Santa Maria, localizadas no estado do Rio Grande do Sul. A emergência desses espaços, por um lado, associa-se a estratégias capitalistas de reprodução do capital, vinculadas a grandes grupos empresariais e sobretudo ao setor imobiliário, que têm na cidade média um mercado consumidor em potencial; por outro lado, indica processos de reestruturação intraurbana em curso. Os shopping centers denotam novas expressões da centralidade, para além dos centros principais, enquanto os condomínios fechados implantados em áreas periféricas representam a dispersão das classes de alta renda, tradicionalmente localizadas nas áreas centrais, promovendo a ampliação da fragmentação socioespacial. Esses fatos, juntos, permitem a utilização do conceito de reestruturação, pressupondo rupturas significativas nas lógicas de estruturação intraurbanas precedentes.

The demand for setting up a wireless LAN internet connectivity is almost mandatory for every commercial building, home, company, and educational institutions. With the growing number and height of buildings as well as the number of users, it has become essential to apply new techniques to provide better wireless network services, especially for security issue with many applications used by an attacker that can decrypt the traditional password to use network resources, that’s lead to poor network performance for providing network services for people authorized to use it. All of that is almost a very challenge issue when applying outdated techniques. In this research a wireless network has been created considering a large number of users in a multi-floor building using a new control system which can solve the problems by setting up RADIUS authentication via that wireless network with a webpage that automatically appears to the user immediately after connecting to the wireless radio signal and automatically gaining an IP address, lead user directly to the temporary page asking him for  authentication, if the user has the right username and password or even sometimes a code called Voucher, he will get a package assigned to his priority. This technology will eliminate the vulnerability on the wireless connection and the unauthorized user will be discarded from the router, in addition of that authorized users will get authenticated to make better use of network resources.

Clusters of galaxies are outstanding laboratories for understanding the physics of supermassive black hole (SMBH) feedback. Here we present the first Chandra, Karl G. Jansky Very Large Array, and Hubble Space Telescope analysis of MACS J1447.4+0827 (z = 0.3755), one of the strongest cool core clusters known, in which extreme feedback from its central SMBH is needed to prevent the hot intracluster gas from cooling. Using this multiwavelength approach, including 70 ks of Chandra X-ray observations, we detect the presence of collimated jetted outflows that coincide with a southern and a northern X-ray cavity. The total mechanical power associated with these outflows (P
cav ≈ 6 × 1044 erg s−1) is roughly consistent with the energy required to prevent catastrophic cooling of the hot intracluster gas (L
cool = 1.71 ± 0.01 × 1045 erg s−1 for t
cool = 7.7 Gyr), implying that powerful SMBH feedback was in place several Gyr ago in MACS J1447.7+0827. In addition, we detect the presence of a radio minihalo that extends over 300 kpc in diameter (P
1.4GHz = 3.0 ± 0.3 × 1024 W Hz−1). The X-ray observations also reveal an ∼20 kpc plumelike structure that coincides with optical dusty filaments that surround the central galaxy. Overall, this study demonstrates that the various physical phenomena occurring in the most nearby clusters of galaxies are also occurring in their more distant analogs.
Time-sequence Spectroscopy of Epsilon CrA: The 518 nm Mg i Triplet Region Analyzed with Broadening Functions
Authors: Rucinski Slavek M.
Published: August 2020

High-resolution spectroscopic observations of the W UMa-type binary ϵ CrA obtained as a time-monitoring sequence on four full and four partial nights within two weeks have been used to derive orbital elements of the system and discuss the validity of the Lucy model for description of the radial-velocity data. The observations had more extensive temporal coverage and better quality than similar time-sequence observations of the contact binary AW UMa. The two binaries share several physical properties and show very similar deviations from the Lucy model: the primary component is a rapidly rotating star almost unaffected by the presence of the secondary component, while the latter is embedded in a complex gas flow and appears to have its own rotation-velocity field, in contradiction to the model. The spectroscopic mass ratio is found to be larger than the one derived from the light-curve analysis, as in many other W UMa-type binaries, but the discrepancy for ϵ CrA is relatively minor, much smaller than for AW UMa. The presence of the complex velocity flows contradicting the assumption of solid-body rotation suggests a necessity of modification to the Lucy model, possibly along the lines outlined by Stȩpień in his concept of energy transfer between the binary components.
Abundance Analysis of New r-process-enhanced Stars from the HESP–GOMPA Survey

Published: August 2020

We present a study on the detailed chemical abundances of five new relatively bright r-process-enhanced stars that were initially observed as part of the SDSS/MARVELS pre-survey. These stars were selected, on the basis of their metallicities and carbon abundances, among a total of 60 stars, for high-resolution spectroscopic follow-up as part of the HESP–GOMPA survey (Hanle Echelle SPectrograph—Galactic survey Of Metal Poor stArs). Here we discuss the three new r-I and two new r-II stars found in this survey. We have carried out a detailed abundance analysis for each of these stars, at a resolving power of R ∼ 30,000, and we compare our results to the existing literature. We could measure three of the first r-process-peak elements (Sr, Y, and Zr) in all five stars, while Ba, Ce, Nd, Sm, Eu, and Dy could be detected among the second r-process-peak elements. Thorium could also be detected in one of the targets, which is found to be an actinide-boost star. We have carried out a comparative study among the subpopulations of the r-process-enhanced stars and other stars of the Milky Way halo population to constrain the origin of this class of objects. These bright r-process-enhanced stars provide an excellent opportunity to study the nucleosynthesis history of this population in great detail, and shed light on their chemical-enrichment histories.
Typification and taxonomic remarks on five species names in Cytisus (Fabaceae)

Published: August 2020

This paper deals with the typification and taxonomy of five Mediterranean Cytisus species. Cytisus affinis, C. candidus, and C. spinescens nom. illeg., non Sieber ex Spreng. were described from Sicily by Karel Bořivoj Presl, Cytisus spinescens was described from Apulia (southern Italy) by Curt Polycarp Joachim Sprengel, and C. villosus was described from southern France by Pierre André Pourret (1788). Lectotypes are here designated for Presl and Sprengel’s names. A neotype is designated for C. villosus. The taxonomic revision of these five names confirmed that C. villosus Pourr. (= Cytisus affinis C.Presl) is the name to be used for the species occurring in the large part of the Mediterranean countries. Cytisus spinescens Sieber ex Spreng. (≡ C. candidus C.Presl = C. spinescens C.Presl, nom. illeg.) is the correct name for the amphi-adriatic species occurring in peninsular Italy, and along the NE coast of the Adriatic Sea. This species does not occur in Sicily and reference to this latter region in the protologues of both C. spinescens C.Presl and C. candidus C.Presl is a misinterpretation due, possibly, to exchange of labels.

Published: August 2020

Reactive Powder Concrete (RPC) could be considered as the furthermost significant modern high compressive strength concrete. In this study, an experimental investigation on the impact of micro steel fiber volume fraction ratio and gamma ray irradiation duration influence upon the compressive strength of RPC is presented. Three volume fraction ratios (0.0, 1.0 and 1.5) % was implemented. For each percentage of the adopted fiber ratios, six different irradiation duration was considered; these are (1, 2, 3, 4, 5 and 6) days. Gamma source (Cs-137) of energy (0.662) MeV and activity (6) mci was used. In a case of zero volume fraction ratio, the experimental results showed that gamma ray had a significant influence on the reducing of the compressive strength varies between (1.2-8.6)% for a period of (1-6) days, respectively. Although there was a decrease in the compressive strength for a state of non-zero volume fraction ratio (1 and 1.5) % varies between (1.0-3.1 and 0.4-1.6) %, respectively, the attained results indicated that gamma ray had no significant effect to reduce the compressive strength of the RPC that’s included micro steel fibers as a volume fraction.
