How Humble Leadership Influences the Innovation of Technology Standards: A Moderated Mediation Model
Authors: Jiang Hong , Liu Wentao , Jia Lili
Published: October 2019

Management researchers have paid increasing attention to the role of humble leadership in innovation activities. The underlying mechanisms through which leader humility influences team innovation and outcomes, however, remain unclear. We aim to investigate the impact of humble leadership on the innovation of technology standards via knowledge exchange and combination and job complexity. We apply the Structural Equation Modelling (SEM) to the survey data from 354 individuals who participated in technology standard innovation activities in China. Our empirical results show that knowledge exchange and combination play a mediating role between humble leadership behavior and the innovation of technology standards. Particularly, we find that job complexity moderates the positive relationship between knowledge exchange and combination and the innovation of technology standards in a nonlinear way. This is the first time that the latent mechanisms of humble leadership have been identified in the innovation of technology standards based on knowledge-based theory.
Improving the Sustainability of the Manufacturing Process by Constructively Optimizing the Parts “Transition Type Fitting”
Authors: Dobrotă Dan , Rotaru Ionela , Nicolescu Florin Adrian , Marin Mădălina
Published: October 2019

Transition type fittings are components often used in the transport facilities of fluid, and which allow the passage from a polyethylene (PE) pipe to a metal pipe. Within the paper, there was carried out a sustainability analysis of the manufacturing process for four types of existing transition fittings, and based upon the findings, there was proposed another type of transition fitting. For this new type of transition fitting, both a sustainability analysis and a finite element method (FEM) analysis were performed. Thus, based upon the analysis, there was found that the new constructive variant of transitional fitting is much more sustainable in the sense that the cost of processing has decreased from 0.77 Euros/part to 0.20 Euros/part, and this proposed transition fitting is resistant to tensile stress at a force of 25,800 N, a very large force that shows that the adopted assembly, for this new type of transition fitting will not yield during the operation.
Assessing Urban Travel Patterns: An Analysis of Traffic Analysis Zone-Based Mobility Patterns
Authors: Chen Yanyan , Zhang Zheng , Liang Tianwen
Published: October 2019

Information and communication technology development has yielded large-scale spatiotemporal datasets, such as mobile phone, automatic collection system, and car-hailing data, which have resulted in new opportunities to investigate urban transportation systems. However, few studies have focused on regional mobility patterns. This study presents a multistep method for exploring traffic analysis zone (TAZ)-based mobility patterns and the corresponding relations with local land use characteristics. Based on a large-scale mobile phone dataset from a major mobile phone operator in Beijing, we applied the K-means clustering algorithm to the hourly aggregated trip data to create clusters of TAZs with similar temporal mobility patterns. Land use characteristics were then derived and correlated with the temporal TAZ-based mobility patterns. Four clusters of TAZs with the similar patterns and intensities of urban activities during given time windows were identified. Land use indicators, such as residence and commercial and business area indicators, were correlated with specific temporal TAZ-based mobility patterns. The proposed multistep method could be applied in other cities to enrich relevant analyses and improve urban design and transportation planning.
The Future of Ex-Ante LCA? Lessons Learned and Practical Recommendations
Authors: Buyle Matthias , Audenaert Amaryllis , Billen Pieter , Boonen Katrien , Van Passel Steven
Published: October 2019

Every decision-oriented life cycle assessment (LCAs) entails, at least to some extent, a future-oriented feature. However, apart from the ex-ante LCAs, the majority of LCA studies are retrospective in nature and do not explicitly account for possible future effects. In this review a generic theoretical framework is proposed as a guideline for ex-ante LCA. This framework includes the entire technology life cycle, from the early design phase up to continuous improvements of mature technologies, including their market penetration. The compatibility with commonly applied system models yields an additional aspect of the framework. Practical methods and procedures are categorised, based on how they incorporate future-oriented features in LCA. The results indicate that most of the ex-ante LCAs focus on emerging technologies that have already gone through some research cycles within narrowly defined system boundaries. There is a lack of attention given to technologies that are at a very early development stage, when all options are still open and can be explored at a low cost. It is also acknowledged that technological learning impacts the financial and environmental performance of mature production systems. Once technologies are entering the market, shifts in market composition can lead to substantial changes in environmental performance.
Understanding Construction Stakeholders’ Experience and Attitudes toward Use of the Structurally Insulated Panels (SIPs) in New Zealand
Authors: Harris Jeremy , Durdyev Serdar , Tokbolat Serik , Ismail Syuhaida , Kandymov Nurmurat , Mohandes Saeed Reza
Published: October 2019

New Zealand faces a housing shortage with construction struggling to meet demand. Structurally insulated panels (SIPs) have been demonstrated internationally as a method of construction which could reduce construction time frames, improve the standard insulation in housing, as well as reduce the amount of waste generated on construction sites. However, anecdotal evidence shows that the SIPs’ adoption is lacking, which is, perhaps, attributed to its industry-wide acceptance level. Thus, in this study, the construction stakeholders, such as architects/designers, builders, territorial authorities and homeowners were targeted to shed light on current status of SIPs use, benefits offered and any barriers inhibiting its industry-wide implementation. This was done through a survey, which was designed to understand the construction stakeholders’ experience levels regarding SIPs use in New Zealand as well as their opinions about any problems associated with the SIPs adoption. Although the stakeholders were happy with the thermal performance offered by SIPs, the results indicate that lack of familiarity and understanding are one of the main barriers to the widespread use of SIPs in New Zealand. Moreover, proper training and clear design information are reported to be crucial to make the building and consenting processes efficient, which will ultimately improve the cost-effectiveness. Despite the barriers (to SIPs adoption) documented by stakeholders, the common belief is that SIPs offer wide-range of benefits to improve performance of the built environment; hence, the stakeholders expressed their willingness to design/build/recommend SIP homes. It is hoped that the findings of this study will guide the industry practitioners in investing their efforts in wider adoption of SIPs in New Zealand.
Estimating the Entropy for Lomax Distribution Based on Generalized Progressively Hybrid Censoring
Authors: Liu Shuhan , Gui Wenhao
Published: October 2019

As it is often unavoidable to obtain incomplete data in life testing and survival analysis, research on censoring data is becoming increasingly popular. In this paper, the problem of estimating the entropy of a two-parameter Lomax distribution based on generalized progressively hybrid censoring is considered. The maximum likelihood estimators of the unknown parameters are derived to estimate the entropy. Further, Bayesian estimates are computed under symmetric and asymmetric loss functions, including squared error, linex, and general entropy loss function. As we cannot obtain analytical Bayesian estimates directly, the Lindley method and the Tierney and Kadane method are applied. A simulation study is conducted and a real data set is analyzed for illustrative purposes.
Developing an Image Manipulation Detection Algorithm Based on Edge Detection and Faster R-CNN
Authors: Wei Xiaoyan , Wu Yirong , Dong Fangmin , Zhang Jun , Sun Shuifa
Published: October 2019

Due to the wide availability of the tools used to produce manipulated images, a large number of digital images have been tampered with in various media, such as newspapers and social networks, which makes the detection of tampered images particularly important. Therefore, an image manipulation detection algorithm leveraged by the Faster Region-based Convolutional Neural Network (Faster R-CNN) model combined with edge detection was proposed in this paper. In our algorithm, first, original tampered images and their detected edges were sent into symmetrical ResNet101 networks to extract tampering features. Then, these features were put into the Region of Interest (RoI) pooling layer. Instead of the RoI max pooling approach, the bilinear interpolation method was adopted to obtain the RoI region. After the RoI features of original input images and edge feature images were sent into bilinear pooling layer for feature fusion, tampering classification was performed in fully connection layer. Finally, Region Proposal Network (RPN) was used to locate forgery regions. Experimental results on three different image manipulation datasets show that our proposed algorithm can detect tampered images more effectively than other existing image manipulation detection algorithms.
Vector-Coupled Flight Controller Design Based on Multivariable Backstepping Sliding Mode
Authors: Han Yang , Li Peng , Ma Jianjun
Published: October 2019

This study aims to address the issues of the simultaneous control of the angle of attack, sideslip angle, and airspeed of a flight in a vectorial form. A vector controller, with a symmetry structure, is developed to transform the attitude and speed control problem into a space-vector tracking problem. We first establish flight vector-coupled dynamics, i.e., describe velocity and angular-velocity vectors in a body-fixed frame, and then propose a multivariable backstepping sliding mode control algorithm along with nonlinear disturbance observers for the vectorial dynamics. The theoretical analysis ensures that the states of the system can be enforced to reach a small neighborhood of the desired sliding manifold. The results of the numerical simulation illustrate the effectiveness and robustness of the combined vector-control scheme.
Research Methodology: Application of Railway Luggage and Package Transportation Scheme Formulation Based on a Dynamic Time–Space Service Network
Authors: Niu Kaige , Liu Jun , Wang Ying
Published: October 2019

In the current market environment, the formulation of a railway luggage and package transport scheme (RLPTS) is often affected by the specific requirements of the transport organization, the complex composition of the transport service network, and the dynamic changes of transport demands, which make it very difficult. In this paper, a two-stage RLPTS formulation method is proposed that can meet not only transport demands with dynamic changes, but also the requirements of transport timeliness. It is used to solve the problem of current RLPTS formulation. First, a dynamic service network for railway luggage and package transport (RLPT) is constructed based on passenger train schedules, and based on this network, an improved A* algorithm is designed to generate feasible path sets for RLPT demand. Then, based on feasible path sets, a flow distribution model aiming at maximizing the total profit of transportation is established to solve the model in order to enable the flow allocated on the path. Finally, an example calculation shows that the method can implement the RLPTS formulation rapidly.

Published: October 2019

In a tribal area of western India, a non-governmental organization implemented a comprehensive sickle cell disease (SCD) program at a secondary level hospital. In a cohort of SCD patients registered during December 2015 to June 2017, we assessed rates of lost to follow-up (LTFU) during the follow-up period using routinely collected data. We compared the uptake of proven interventions and indicators of disease severity from one year prior to registration until the end of the study (June 2018). Of 404 patients, the total follow-up duration was 534 person-years (PY). The rate (95% CI) of LTFU was 21 (17.5–25.3) per 100 PY. The proportion of people who received the pneumococcal vaccine improved from 10% to 93%, and coverage of hydroxyurea improved from 3.5% to 88%. There was a statistically significant decrease in rates (per 100 PY) of pain crisis (277 vs 53.4), hospitalization (49.8 vs 42.2), and blood transfusion (27.4 vs 17.8) after enrollment in the SCD program. Although clinical intervention uptake was high, one quarter of the patients were LTFU. The study demonstrated significant reductions in disease severity in SCD patients.
Reconstructing the Dissemination Dynamics of the Major HIV-1 Subtype B Non-Pandemic Lineage Circulating in Brazil

Published: October 2019

Non-pandemic variants of the Human Immunodeficiency Virus Type 1 (HIV-1) subtype B accounts for a significant fraction of HIV infections in several Caribbean islands, Northeastern South American countries and the Northern Brazilian states of Roraima and Amazonas. In this paper, we used a comprehensive dataset of HIV-1 subtype B pol sequences sampled in Amazonas and Roraima between 2007 and 2017 to reconstruct the phylogeographic and demographic dynamics of the major HIV-1 subtype B non-pandemic Brazilian lineage, designated as BCAR-BR-I. Our analyses revealed that its origin could be traced to one of many viral introductions from French Guiana and Guyana into Northern Brazil, which probably occurred in the state of Amazonas around the late 1970s. The BCAR-BR-I clade was rapidly disseminated from Amazonas to Roraima, and the epidemic grew exponentially in these Northern Brazilian states during the 1980s and 1990s, coinciding with a period of economic and fast population growth in the region. The spreading rate of the BCAR-BR-I clade, however, seems to have slowed down since the early 2000s, despite the continued expansion of the HIV-1 epidemic in this region in the last decade.
Differential Pathogenicity of SHIV KB9 and 89.6 Env Correlates with Bystander Apoptosis Induction in CD4+ T cells
Authors: Mehmetoglu-Gurbuz Tugba , Joshi Anjali , Garg Himanshu
Published: October 2019

SHIV variants KB9 and 89.6 show differential pathogenesis in primate models with KB9 causing rapid CD4 decline while 89.6 failing to induce disease. We attempted to determine whether the differential pathogenicity of KB9 versus 89.6 was a result of differential bystander apoptosis inducing potential (AIP) of the Env glycoproteins from these viruses. We find that the KB9 Env was highly potent at inducing bystander apoptosis in CD4+ target cells compared to 89.6 Env. Cell death induction by KB9 showed classical signs of apoptosis including mitochondrial depolarization, caspase activation and PARP cleavage. Inhibiting Env mediated fusion by T20 peptide inhibited KB9 mediated bystander apoptosis. KB9 and 89.6 differed in terms of co-receptor usage with 89.6 preferring CXCR4 while KB9 using both CXCR4 and CCR5 with equal efficiency. Our study suggests that higher bystander AIP of KB9 Env compared to 89.6 may be the basis for the differential pathogenesis of these viruses.
ANALISIS METODE 360 DERAJAT UNTUK PENILAIAN KINERJA KARYAWAN PADA SISTEM INFORMASI MANAJEMEN SUMBER DAYA MANUSIA
Authors: Susanto Rani , Andriana Anna Dara
Published: October 2019

Sistem Informasi Manajemen Sumber Daya Manusia atau SIM SDM digunakan untuk mengorganisir tatakelola manajemen sumber daya manusia di perusahaan yang mendukung proses pengambilan keputusan, dimulai dari proses perekrutan dan penerimaan karyawan, penilaian kinerja karyawan serta prosedur lain seperti cuti, pensiun hingga pelatihan. Penilaian Kinerja karyawan bertujuan agar perusahaan dapat mengevaluasi hingga melakukan pengembangan terhadap kinerja karyawannya.

Masalah dalam proses penilaian kinerja karyawan yaitu sering terjadi kesalahan dimana penilaian yang dilakukan dinilai tidak objektif dan masih diragukan hasilnya. Hal ini disebabkan karena penilaian dilakukan berdasarkan perkiraan dan hanya dilihat dari satu sisi penilai saja yaitu Atasan sehingga tidak ada pertimbangan lain saat melakukan penilaian. Masalah lain dari proses penilaian ini yaitu belum adanya kriteria dan syarat untuk penilaian kinerja karyawannya karena hanya absensi karyawan saja yang menjadi kriteria yang digunakan untuk penilaian.

Metode 360 derajat adalah metode penilaian kerja yang memungkinkan karyawan memperoleh penilaian dari segala arah, dari atasan bawahan dan rekan kerjanya. Metode ini memudahkan pihak manajerial untuk memberikan evaluasi terhadap karyawan berupa keputusan promosi, demosi, mutasi, pemberian bonus, pemberian pelatihan maupun pemberian pengarahan. Dari analisis yang sudah dilakukan dapat disimpulkan bahwa Metode ini dapat digunakan untuk proses penilaian kinerja karyawan dan juga dapat membantu pihak perusahaan dalam mendapatkan rekomendasi hasil penilaian yang lebih objektif.

Brand Management: A Scientific Art of Branding a Country
Authors: Bhardwaj Garima
Published: October 2019

In 21st century, the first criteria that defines the perception of a nation is its economic status. In order to uplift economic status, countries try to reap their USPs by marketing them and positioning them as a brand, for attracting market from across the globe.Even when a country does not consciously manage its name as a brand, people still have images of countries that can be activated by simply voicing the name. Country images are likely to influence people’s decisions consciously or unconsciously, in making multiple other decisions such as Purchasing, Investing, Changing Residence, Traveling and many more. The world’s leading economies for 2019-20, including the USA, China, Japan have a renowned global image of its own in their respective field of uniqueness and that’s how, consistent nurturing of that image helps in positioning a nation as a specific brand.The economic power centres of the world have been changing from west to east and by the end of 2050, (A report by PwC, London) the current developing economies may become one of the largest economies of the world with the help of their smart global self-positioning strategies. India also, has huge stamina to be the 2nd largest economy by then, if the nation’s numerous factors have been marketized in such a way that can position this nation as a big brand, in so many areas, ultimately leading the nation towards a better global position in Diplomatic, Prestigious and Economic ways.

The feasibility of surgical patch osteoplasty in isolated left main coronary stenosis.
Authors: Hassan Essam , Aboollo Moustafa , Elghoneimy Yasser
Published: October 2019

Background: Coronary artery bypass grafting (CABG) is perceived as the most common treatment for left main coronary artery (LMCA) disease with good results compared to left-main stenting or medical therapy.  Surgical patch angioplasty (SPA) may present a substitute to the standard CABG in patients with isolated LMCA disease, and it offers physiological antegrade myocardial perfusion, keeps ostial patency and saves bypass material. The objective of this study is to demonstrate the feasibility of patch osteoplasty in patients with isolated LMCA stenosis.

Methods: This is a retrospective study performed on eight patients with angiographically proven ostial or proximal LMCA stenosis who underwent surgical patch angioplasty. Two of them had associated right coronary artery bypass grafting. All patients were performed with cardiopulmonary bypass and saphenous vein patch. An anterior approach with transverse aortotomy was utilized in all cases. Patients were followed-up clinically for a mean period of 14 months (ranging from 26 to 6 months) for recurrence of symptoms and any postoperative complications.

Results: The early postoperative period was uneventful in all patients. No perioperative mortality was reported. Two patients had postoperative atrial fibrillation, and one patient with poor left ventricular function required preoperative intra-aortic balloon pump. Angiography was done in the first three cases, and all showed no restenosis and no vein patch dilatation.

Conclusion: Surgical patch angioplasty may be a safe and suitable alternative to CABG in selected patients with isolated ostial LMCA stenosis. Further studies are needed to compare the results of the SPA with those of standard CABG and LMCA stenting.

This paper explores the possibility of using the mythological interpretations of celestial bodies to link the story to the long scale cycles related with eclipses.
Abraham Zabludovsky as a representative of brutalism in Mexican architecture
Authors: Żuławska-Sobczyk Elżbieta
Published: October 2019

Brutalism was a trend that appeared in architecture in response to the International Style, with preference forthe aesthetics of machines and clean geometric forms striving for lightness and stylistic purity. Le Corbusieris considered to be the precursor of this style, but its concept was best presented both in theory and practiceby Alison and Peter Smithson. Th e idea of expressing form, the sincerity of material, and deriving fromwhat could be found in the area of construction has spread throughout the world. In Mexico, an architect ofPolish descent, Abraham Zabludovsky, became an advocate of Brutalism and, along with Teodor Goznalezde Leon, has created many buildings which are now iconic for the of Mexico city. Th is study aims to presentthe case of Zabludovsky’s architectural concepts.
Speckle Observations and Orbits of Multiple Stars

Published: October 2019

We report results of speckle-interferometric monitoring of visual hierarchical systems using the newly commissioned instrument NN-EXPLORE Exoplanet and Stellar Speckle Imager at the 3.5 m WIYN telescope. During one year, 390 measurements of 129 resolved subsystems were made, while some targets were unresolved. Using our astrometry and archival data, we computed 36 orbits (27 for the first time). Spectro-interferometric orbits of seven pairs are determined by combining positional measurements with radial velocities measured, mostly, with the Center for Astrophysics digital speedometers. For the hierarchical systems HIP 65026 (periods 49 and 1.23 yr) and HIP 85209 (periods 34 and 1.23 yr) we determined both the inner and the outer orbits using astrometry and radial velocities and measured the mutual orbit inclinations of 11.°3 ± 1.°0 and 12.°0 ± 3.°0, respectively. Four bright stars are resolved for the first time; two of those are triple systems. Several visual subsystems announced in the literature are shown to be spurious. We note that subsystems in compact hierarchies with outer separations less than 100 au tend to have less eccentric orbits compared to wider hierarchies.

Published: October 2019

Protoplanets and circumplanetary disks are rather elusive in their thermal IR emission. Yet they are cornerstones to the most popular interpretations for the protoplanetary disk structures observed in the gas and dust density fields, even though alternative theories exist. The gaseous velocity field should also bear the imprint of planet–disk interactions, with non-Keplerian fine structure in the molecular-line channel maps. Such kinks or wiggles are affected by the optical depth structure and synthesis imaging limitations, but their detail could in principle be connected to the perturber by comparison with hydrodynamical simulations. These predictions appear to have been observed in HD 163296 and HD 97048, where the most conspicuous wiggles are interpreted in terms of embedded planets. The velocity centroid maps may allow for more robust indirect detections of embedded planets. The non-Keplerian velocity along the planetary wakes undergoes an abrupt sign reversal across the protoplanet. After subtraction of the disk rotation curve, the location of the perturber should be identifiable as a Doppler flip in velocity centroid maps. Here we improve our rotation curves in an extension to disks with intermediate inclinations, which we apply to deep and fine angular resolution CO isotopologue data sets. Trials in HD 163296 and in HD 97048 yield nondetections. However, in HD 100546 we pick up a conspicuous Doppler flip, an important part of which is likely due to radial flows. Its coincidence with a fine ridge crossing an annular groove inside the continuum ring suggests a complex dynamical scenario, in which the putative protoplanet might have recently undergone pebble accretion.

Authors: Keiser Megan M. , Turkelson Carman
Published: October 2019

Background:

The use of simulation-based learning experiences (SBLE) with nurse practitioner (NP) students is largely unexplored. The purpose of this pilot project was to develop, implement, and evaluate a simulated patient (SP)-SBLE to improve confidence and evaluate clinical performance and reasoning in Adult-Geriatric Acute Care NP (AG-ACNP) students.

Method:

A mixed-methods design was used to evaluate an SP-SBLE on AG-ACNP student clinical performance and reasoning.

Results:

Self-confidence scores and themes from reflections indicated that students perceived this as a valuable experience that enhanced learning and confidence.

Conclusion:

Results supported the use of SP-SBLEs to improve confidence in clinical performance and reasoning with AG-ACNP students.

Creating a Gerontological Nursing Digital Repository Within a Learning Management System
Authors: Kennedy-Malone Laurie , Lekan Deborah , Von Cannon Lois Lewis , Ransom Collins Susan Kay , Kayler DeBrew Jacqueline
Published: October 2019

Background:

Faculty who teach gerontological nursing are challenged to deliver competency-based baccalaureate nursing education. Because our courses are divided into multiple sections and taught by a variety of faculty, the need for a peer-reviewed, curated repository of gerontological learning materials was conceived.

Method:

Syllabi for prelicensure and RN-to-baccalaureate nursing (BSN) degree gerontological courses were reviewed. Stufflebeam's Content, Input, Process and Product (CIPP) model of program evaluation provided a framework to guide the process of identifying existing resources and gaps in eLearning materials. Using the Learning Object Review Instrument, faculty determined the relevance and applicability of eLearning materials.

Results:

A crosswalk between the syllabi and the American Association of Colleges of Nursing-recommended geriatric nursing competencies was completed to evaluate eLearning materials identified as valuable. Consensus was reached, and content was placed in the learning management system.

Conclusion:

This project can serve as a model for other course faculty and faculty in other specialty areas to enhance the curriculum by providing readily available, multifaceted instructional resources.

The Use of Intravitreal Gas for the Treatment of Ocular Hypotony After Glaucoma Filtration Surgery
Authors: Friedman Scott M. , Mahootchi Ahad
Published: October 2019

Hypotonous maculopathy is a serious complication of glaucoma filtration surgery. A patient with hypotonous maculopathy due to excessive filtration was treated with intravitreal gas. During the next several months, the intraocular pressure increased and the visual acuity improved. Intravitreal gas is useful for the treatment of hypotonous maculopathy due to excessive aqueous filtration.

Does Postoperative Near Visual Acuity Predict Macular Hole Closure?
Authors: Dhalla Mandeep S. , Desai Uday R. , Gandolfo Cristian
Published: October 2019

To determine whether prone postoperative near visual acuity following macular hole surgery can be used as a reliable indicator of successful hole closure, data from 21 patients undergoing macular hole surgery were collected. Seventeen of the 18 patients with hole closure and all 3 patients with persistent macular holes had a Rosenbaum acuity better than preoperative visual acuity, yielding 94% sensitivity, 0% specificity, 85% positive predictive value, and 0% negative predictive value. Fourteen of the 18 patients with macular hole closure and all 3 patients with persistent macular holes had a Rosenbaum acuity better than 20/40, yielding 78% sensitivity, 0% specificity, 82% positive predictive value, and 0% negative predictive value. Although postoperative near visual acuity can predict macular hole closure with 94% sensitivity, the test is not clinically useful to predict hole closure because of the high surgical success rate of macular hole surgery. The test could be useful in encouraging patients to maintain head prone positioning and alleviate patient anxiety. [Ophthalmic Surg Lasers Imaging 2006;37:244-246.]

Published: October 2019

BACKGROUND AND OBJECTIVE Corneal epithelial sheet cultured on amniotic membrane ex vivo has been developed for the treatment of severe ocular surface disorders. In this study, human corneal epithelial sheets cultured on amniotic membranes were analyzed using a laser scanning confocal microscope. MATERIALS AND METHODS Human corneal epithelial cells were cultured on four sheets of amniotic membrane, and they were examined layer by layer using the laser scanning confocal microscope. RESULTS The superficial layer cells were mosaic in appearance. In the superficial layer, focal areas of slender and elongated cells were noted. In addition, highly reflective materials were noted. Basal epithelial cells of the corneal epithelium sheet at a slightly deeper plane displayed mosaic pattern with smaller cells. At a slightly deeper plane, the basement membrane of amnion showed relatively bright homogeneity. CONCLUSION The laser scanning confocal microscope can examine the morphology of human corneal epithelial cells cultured on amniotic membranes.

Published: October 2019

The suitability of three new lightweight aggregates containing carbon fiber residues (CAs) as components in structural lightweight concrete has been studied. Prismatic concrete specimens were prepared using these CAs as a coarse fraction. Additional specimens of normal-weight aggregate, commercial lightweight aggregate and mortar were prepared for comparison. The CA-concrete samples (CACs) have yielded compressive strength values between 35 and 55 MPa as well as low density and thermal conductivity results. Furthermore, the CACs have displayed the highest ratios of mechanical strength over density and the thermal conductivity, which means that there is a better balance between their mechanical and physical properties than in the other samples studied. These results indicate that the new CAs could have great potential for use in structural lightweight concrete, also complying with the principles of the Circular Economy.
