FLAUT: A mutual sensitivity improvement through matched pipe, cavity and thin plate resonance

Electrostatic transducers promises a great potential in alternative to piezoelectric transducer based on certain advantages such as inherently wide bandwidth and good acoustic matching to air due to the membrane’s low acoustics impedance. There are two basic designs that are popular among electrostatic ultrasonic transducer developer – rigid backplate and micromachine backplate. This paper presents a methodology for improving the sensitivity of an air-coupled ultrasonic transducer by coupling the resonating thin plate, cavity and pipe in a single cell. The proposed device is termed Fluidically Amplified Ultrasonic Transducer (FLAUT) for an air-coupled application. Investigation of the concept of matched thin plate, cavity and pipe, of which the individual geometry is expected to mutually enhance one another. Analytical modelling is utilized to the matched thin plate, cavity and pipe. The analytical modelling identifies the required geometry for the FLAUT based on the matched operating resonant frequency of 25 kHz. At the end of the paper the prototype of FLAUT is presented where the device was fabricated using additive manufacturing process (3-D printing) which consist of a 50 µm Kapton thin film over a micro stereolithography designed backplate. Here aluminum is coated as the electrode utilizing the thermal evaporation process for both the Kapton film and the backplate. A laser interferometer is utilized to measure FLAUT thin plate displacement which indicates the device is running at 25 kHz fundamental mode. A 30 dB difference is also observed between the deformation velocity of the cavity active region and its surrounding.
Utilization of Satellite Images-Based Indices for Assessment of Al-Hammar Marsh Restoration plan

 Used a series of spectral indices in Ecological wetland assessment.  Develop a satellite-based model to automated classification of the marshes land cover.  Spatiotemporal assessment of the efficiency of implementing restoration plans. Wetland landscape characterization is an important component of determining the degree to which wetlands improve environmental conditions. The present study aims to create a model used to automated extraction of the land cover of the western part of the Al-Hammar Marsh south of Iraq, and then monitor the change in land cover overtime. A model builder in ArcGIS created based on a series of spectral-based indices included the Normalized Difference Vegetation Index (NDVI), the Normalized Difference Moisture Index (NDMI), and the Normalized Difference Water Index (NDWI), the OLI satellite images from 2013 to 2020, ENVI 5.3 and ArcGIS 10.4 were used to achieve this goal. The results were six land cover classes: water, density vegetation, medium dense vegetation, low dense vegetation, wet barren land and, dry barren land. From the monitoring of the changing trend, it is clear that there is no improvement in the vegetation area, only a slight temporal improvement to 48% in 2017, an increase in water area for the years 2019 and 2020 to 47.33%, and 42.85% from the total area of the marsh respectively. The highest percentage was in 2019 while decreasing to the lowest rate of 14.05% for the year 2018. The developed model was accepted and can be applied for reflectance Landsat 8 data in the study area and can be applied in the southern Iraqi marshes. It also can be applied to other types of sensors, but according to determinants. A R T I C L E I N F O Handling editor: Wasan I. Khalil

Jelena Jelicic Thomas Stauffer Larsen Henrik Frederiksen 1,2 Bosko Andjelic 3 Milos Maksimovic Zoran Bukumiric 1Department of Hematology, Odense University Hospital, Odense, Denmark; 2Department of Clinical Research, University of Southern Denmark, Odense, Denmark; 3Department of Haematology, Blackpool Victoria Hospital, Lancashire Haematology Centre, Blackpool, UK; 4Department of Ophthalmology, Aalborg University Hospital, Aalborg, Denmark; 5Department of Statistics, Faculty of Medicine, University of Belgrade, Belgrade, Serbia Background and Aim: Based on advances in the diagnosis, classification, and management of diffuse large B-cell lymphoma (DLBCL), a number of new prognostic models have been proposed. The aim of this study was to review and compare different prognostic models of DLBCL based on the statistical methods used to evaluate the performance of each model, as well as to analyze the possible limitations of the methods. Methods and Results: A literature search identified 46 articles that proposed 55 different prognostic models for DLBCL by combining different clinical, laboratory, and other parameters of prognostic significance. In addition, six studies used nomograms, which avoid risk categorization, to create prognostic models. Only a minority of studies assessed discrimination and/or calibration to compare existing models built upon different statistical methods in the process of development of a new prognostic model. All models based on nomograms reported the c-index as a measure of discrimination. There was no uniform evaluation of the performance in other prognostic models. We compared these models of DLBCL by calculating differences and ratios of 3-year overall survival probabilities between the highand the low-risk groups. We found that the highest and lowest ratio between lowand high-risk groups was 6 and 1.31, respectively, while the difference between these groups was 18.9% and 100%, respectively. However, these studies had limited duration of follow-up and the number of patients ranged from 71 to 335. Conclusion: There is no universal statistical instrument that could facilitate a comparison of prognostic models in DLBCL. However, when developing a prognostic model, it is recommended to report its discrimination and calibration in order to facilitate comparisons between different models. Furthermore, prognostic models based on nomograms are becoming more appealing owing to individualized disease-related risk estimations. However, they have not been validated yet in other study populations.

New phenomena for clinicians, model of Candida albicans mobilization before and after biofilm formation in the intestinal mucosa of Wistar rats (Rattus norvegicus)

Background and Aim: The virulence and antifungal resistance of Candida albicans are recently known for their ability to form biofilm. This research aimed to construct an in vivo model of C. albicans biofilm in Wistar rats' intestinal mucosa and study their mobilization while in a planktonic and biofilm formation. In this study, there was one treatment group that was treated with three antibiotics, immunosuppressants, and C. albicans. Materials and Methods: This study was divided into control and treatment groups. The data sampling was conducted after C. albicans inoculation. The C. albicans biofilm formation stage was monitored with colony-forming units method calculation every week post-inoculation and then observed by the confocal laser scanning microscope. Results: The planktonic C. albicans overgrowth occurred up to 14 days after inoculation. The formation and maturation of C. albicans biofilm in the intestinal mucosa started in the 28th and 35th-day post-inoculation, respectively. The density of planktonic C. albicans in the stool was dramatically decreased on the 35th day. Before the biofilm formation, the planktonic Candida was carried away by food scraps to be released as a stool. However, there were minuscule or no planktonic Candida observed in the stool during and after biofilm formation. Instead, they were attached to the caecum's mucosa as a biofilm. Conclusion: We have proved that the planktonic C. albicans with its mobile nature were carried into the stool along with the rest of the feed, as we observed a lot of C. albicans cells found in the stool. Meanwhile, on day 28 after administration of antibiotics and immunosuppressants, no C. albicans was found in the stool samples, and at the same time, we observed C. albicans cells and their matrix attached to the intestinal mucosa as a biofilm.
Personal and domiciliary hygiene practices and its association with incidence of infectious diseases among children aged 6-59 months

Background: Over 200 million under-five-children born in low-income countries are at risk of not reaching their development potential and infectious diseases are the leading cause of development deficits in these regions.Methods: A cross-sectional study was conducted to investigate personal and household hygiene practices among 154 mothers and their association with the incidence of infectious diseases among 167 children aged 6 months to 59 months in Patuakhali district, Bangladesh.Results: Only 13.6% of the mothers had proper hand washing knowledge. Besides, 14% and 53.9% of the mothers washed their hands with soap and only with water respectively before feeding their child. About 68.2% of mothers prepared food on the ground and half (49.5%) of the toilet did not have a hand washing location beside it. The risk of childhood infectious disease was significantly associated with hand washing of mothers before feeding a child (OR: 2.3, 95% CI: 1.5-4.1, p<0.05) and hand washing of child before eating (OR: 3.4, 95% CI: 1.8-5.7, p<0.05). Conclusions: Hand washing agents were inadequate and compliance to hand washing was poor. Therefore, the continuous focus is needed on the mother's awareness construction to increase the compliance to hand washing practice among mothers as well as their child with soap, especially during child feeding.
COWORKING SPACES IN CHINA: DEVELOPING A NEW STRATEGY OF REUSING INDUSTRIAL HERITAGE PROPERTIES UNDER SHARING ECONOMY

Abstract. This paper investigates the spatial pattern and operating mechanism of coworking spaces based on existing practices in Shanghai with focus on the rising phenomenon of industrial heritage-based coworking spaces. The geographical distribution of the coworking clusters along the riverside of Huangpu River was analyzed refer to the abundant industrial properties remains, due to some historical reasons in modern history as well as local contribution in advancing creativity to support cultural-led regeneration. On the basis of the spatial analysis and value interpretation of those coworking spaces which retrofitted from industrial heritages, the paper proposes a conservative strategy in presenting the cultural and social value of the industrial heritages in coworking context, through the provision of underpinning urban identity and cultural meaning with contemporary social working style. To conclude, we discuss the applicability of the conservation-based strategy by highlighting its attributes in community base and corresponding advantages in cultivating conservation awareness grassrootly and innovatively in workplace, hoping to shed lights to further enhancement on exploring the urban philosophies under current governmental policies and political emphasis of sharing economy and urban renewal in China.

THE DEAD-BOX PROTEIN CSHA FROM Staphylococcus aureus Mu 50 EXHIBITS RIBONUCLEASE ACTIVITY

DEAD-box proteins play important roles in many RNA processes ranging from RNA synthesis to RNA decay. Furthermore, it has been reported that some bacterial DEAD-box proteins known to be components of the RNA degradosome do not cleave RNA substrates directly. However, the role of DEAD-box proteins in RNA degradation is poorly understood. The present study demonstrated that the DEAD-box protein CshA from the vancomycin-resistant Staphylococcus aureus strain Mu50 possesses RNA degradation activity, ribonuclease activity. Despite having RNA-dependent ATPase activity, CshA did not exhibit RNA helicase activity in vitro. Instead, CshA catalyzed the degradation of single-stranded RNAs of various duplex RNA substrates to form blunt-end RNA products. Thus, we suggest that the ribonuclease activity of the DEAD-box protein CshA may contribute to RNA remodeling in the bacterial RNA degradosome. To our knowledge, this study is the first to report that a DEAD-box protein from a pathogenic bacterium is implicated in multiple ATP-independent activity on RNA, such as degradation.

Focus on Gradientwise Control of the Surface Acetylation of Cellulose Nanocrystals to Optimize Mechanical Reinforcement for Hydrophobic Polyester-Based Nanocomposites

Surface acetylation of cellulose nanocrystals (CNCs) imposes an important effect on CNC-related mechanical enhancement of hydrophobic polyester-based composites, of which interfacial properties still need optimization. In the present work, the surface acetylation of CNCs was adjusted as a gradient of above ca. 10%. Then, we found that the surface energy of acetylated CNCs (ACNs) decreased and thus their hydrophobicity increased as the surface acetylation degree increased. Hence, the ACNs with varied degrees of acetyl substitution (DSsurface-acetyl) values were attempted to reinforce a kind of hydrophobic polyester, poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (PHB). The results indicated that a smaller discrepancy in the surface energy between the CNC surface and the PHB matrix was obtained, as the surface acetylation degree increased, and then, the affinity and interaction between the two components increased, which improved the homogeneous distribution of ACNs in the PHB matrix. Besides, in comparison to the nanocomposites filled with 15 wt % unmodified CNCs, the tensile strength of those with ACNs of 62.9% DSsurface-acetyl was 43.3% higher. This study was the first attempt to adjust the surface substitution degrees with a gradient profile for the surface modification of CNCs and prove that acetylation gradient control is an effective and facile strategy to optimize the mechanical properties.
The Mediating Role of Affective Experience to The Effect of Online Retail Ethic on Repurchase Intention: Indonesian Y and Z Generation Perspective

Ethical violations are more likely to occur in online transactions compared to face-to-face transactions, and have been trigging negative perception regarding online retail ethic and negative experience of customer. Those are identified as the major problems causing consumers’ hesitance toward taking decision for shopping online. This study is to investigate the effect of consumer perception of online retail ethic on repurchase intention with the affective experience as a mediation variable. An online survey conducted toward customer between 17–40 age and have experience in purchasing product online in Indonesia. The results show that consumer perception of online retail ethic effects affective experience and affective experience effects repurchase intention. Consumer perception of online retail ethic also has direct effects on repurchase intention. Thus, the affective experience partially mediates the effect of consumer perception regarding online retail ethic and repurchase intention.
It’s now or never! Future discounting in the application of the online privacy calculus

Many people engage in extensive use of networked digital systems despite concerns over their privacy, a phenomenon called the “online privacy paradox. ” Although privacy calculus research has argued that the benefits of usage usually outweigh the expected privacy losses, it is unclear why people come to this conclusion. We argue that users treat decisions about digital media use as intertemporal choices; that is, they mentally shift into the future the potential damage connected with risk-taking while being convinced of the immediate enjoyment of the benefits of technology use. An online survey conducted among German users for three use cases—e-commerce, online political participation, and self-tracking—indicated that users expect benefits to materialize earlier than associated costs and that the earlier the benefits occur, the higher the amount of benefits users expect. The expected time of the occurrence of benefits and risks explains digital media use in addition to cost–benefit calculations, suggesting a time-discounting bias.
State of Health Prediction of Lithium-Ion Batteries Based on the Discharge Voltage and Temperature

Accurate state of health (SOH) prediction of lithium-ion batteries is essential for battery health management. In this paper, a novel method of predicting the SOH of lithium-ion batteries based on the voltage and temperature in the discharging process is proposed to achieve the accurate prediction. Both the equal voltage discharge time and the temperature change during the discharge process are regarded as health indicators (HIs), and then, the Pearson and Spearman relational analysis methods are applied to evaluate the relevance between HIs and SOH. On this basis, we modify the relevance vector machine (RVM) to a multiple kernel relevance vector machine (MKRVM) by combining Gaussian with sigmoid function to improve the accuracy of SOH prediction. The particle swarm optimization (PSO) is used to find the optimal weight and kernel function parameters of MKRVM. The aging data from NASA Ames Prognostics Center of Excellence are used to verify the effectiveness and accuracy of the proposed method in numerical simulations, whose results show that the MKRVM method has higher SOH prediction accuracy of lithium-ion batteries than the relevant methods.

Measuring The Impact of Intellectual Capital on Travel Agencies’ Innovation Performance: Evidence from Egypt

(JAAUTH) Vol. 21, No. 2, (December 2021), PP.150-161. This study aims to assess the impact of intellectual capital on the innovation performance of Egyptian travel agencies. To achieve this, the researchers used a deductive approach as well as a quantitative method. A semi-structured questionnaire was distributed to 250 travel agencies from 1008 Egyptian travel agencies in class A was collected by simple random sampling technique. Furthermore, the researchers reviewed the literature regarding intellectual capital and the performance of innovation. Structural equation modeling (SEM) was employed for the quantitative analysis. Also, Amos software version (26) utilised to perform the structural equation modeling analysis. According to the study's findings, two dimensions of intellectual capital (Human and Organizational) have a positive impact on the performance of innovation within the Egyptian travel agencies, while the dimension of social/relational capital has a weak negative impact on the innovative performance of Egyptian travel agencies. As a direct consequence, to achieve innovation performance, travel companies must strengthen their intellectual capital especially the human and organizational capital dimensions.
