Published: July 2020

В данном исследовании рассмотрена информационная энтропия проектно-ориентиованных организаций в рамках энергоэнтропийной концепции. Установлена взаимосвязь между энергоэнтропией и информационной (структурной) энтропией проектно-ориентированных организаций. Построена концептуальная модель формирования информационной энтропии проектно-ориентированных организаций и ее влияния на энергоэнтропию. Представленный подход соответствует интегральному рассмотрению «информационных (структурных)» и «энергетических» процессов организации, что в наибольшей степени отражает реальные условия и сущность деятельности организаций. Представлен подход к идентификации сущности событий, вероятности которых формируют информационную энтропию проектно-ориентированной организации. В основе подхода лежит формирование интервалов на диапазоне значений с учетом их нормального закона распределения. В процессе исследований установлена взаимосвязь между информационной энтропией проекта и законом распределения его результатов. Обосновано, что борьба с энтропией обеих видов является борьбой за уменьшение дисперсии результатов деятельности организаций, что может быть обеспечено благодаря проектно-ориентированному управлению. Преимуществом проектно-ориентированного управления является то, что оно позволяет снизить указанные дисперсии, за счет: гибкой системы распределения человеческих ресурсов по проектам с учетом их ценности; сосредоточения проектной команды исключительно на конкретном проекте и обеспечения ею формирование таких условий во внешней среде, которые более четко прогнозируемы, а, следовательно, обладают минимальной дисперсией.
COMPLEX EVENT PROCESSING APPROACH ON SUBSCRIBERS’ DATA OF TELECOM OPERATOR
Authors: Zhumekenov А.
Published: July 2020

Nowadays, the usage of mobile phones reached extremely large worldwide proportions and increasing dramatically, there is a stronger need to decrypt the important information that is hidden among them. Even all needed information is gained, processes of companies remain static and can’t be changed dynamically to adapt to actual business needs, reducing the advantages that can be achieved. Every second, millions of raw information are generating by mobile users, which handled by Telecom operators in data servers. By using Complex Event Processing (CEP) approach in real-time, we can obtain the information that really matters to our business and use it to monetize the vast amount of data that is being collected through mobile phone usage. In this paper, we present an internally developed framework that combines the strengths of CEP and business process implementations, which allows us to react to the needs of today’s fast-changing environment and requirements. We demonstrate 3 simple use case scenarios to show the effectiveness of the CEP approach in our situation. The importance of implementing the CEP approach on subscribers’ data should not be overlooked as means of trying to capitalize on new services but have to be considered as a challenge to give subscribers the opportunity to get more customized offers and services.

Pediatric rheumatologists’ perspective on corona
virus disease 2019
Authors: ÇİÇEK Sümeyra Özdemir , KISAARSLAN AYŞENUR PAÇ
Published: July 2020

Corona Virus Disease 2019 (COVID-19) has become a pandemic affecting the entire the world.
Rheumatologists may play an important role in the management of COVID-19 cases owing to their
experiences on inflammation and macrophage activating syndrome (MAS), one of the most important
complications of COVID-19. Here, we present the applicability of pediatric rheumatology treatment
methods on COVID-19 therapy, and management of children with rheumatic diseases using immune
suppressive treatments, in this pandemic season. COVID-19 causes severe acute respiratory distress
syndrome (SARS) in about 20% of infected patients. The virus specifically recognizes the angiotensin
converting enzyme 2 (ACE2) receptor by its spike protein. In patients whose immunomodulatory capacities
are not strong enough, the virus can trigger a severe cytokine storm. The rheumatologist may play an
important role to avoid this complication with a timely treatment. In COVID-19 patients, by detecting
elevated serum ferritin levels, cytokine storm syndrome can be recognized early, and the necessary
treatments can be initiated on time. Anti-rheumatic drugs, such as hydroxychloroquine, colchicine,
interleukin-1 and interleukin-6 blockers, JAK inhibitors, TNF inhibitors are used in the treatment of
COVID-19 at different stages of the disease. Another very important issue is the management of patients
with rheumatic diseases in this pandemic season. The increased risk of infection is an important concern
in patients with rheumatic disease who are receiving immunosuppressive drugs. Various rheumatism
associations have recommended the continuation of anti-rheumatism treatments to control of chronic
inflammatory status, based on the experience so far

Authors: VATANSEVER Zehra , ÖZSOYLU Serkan , KENDİRCİ Mustafa , AKYILDIZ Basak
Published: July 2020

Background: The aim of this study is to evaluate the thiamine pyrophosphate deficiency and effects on
critical illness hyperglycemia in pediatric intensive care.
Materials-Methods: 126 critically ill children included to the study which applied to Erciyes University
Faculty of Medicine, Department of Pediatric Intensive Care Unit (ICU). Age, sex, diagnosis and presence
of malnutrition in admission to ICU; Pediatric risk of Mortality III (PRISM III) and Pediatric Logistic Organ
Dysfunction (PELOD) scores; mechanical ventilation and length of stay in ICU was evaluated. Blood
glucose, thiamine pyrophosphate, cortisol, insulin, C-peptide, HbA1c level, serum lactate in blood gas
were analyzed at the time of application.
Results: The patients grouped based on blood glucose levels, the group whose glucose level in blood
is more than 150 mg/dl (n:75); PRISM and PELOD scores were high, mechanical ventilation and length
of stay in intensive care were longer, thiamine pyrophosphate levels were lower (p<0.001, p=0.005,
p=0.008, p<0.001, p<0.01). In case of blood glucose >150 mg/dl (n:51) and thiamine pyrophosphate <180
nmol/l is together; mortality increases 3.342-fold and the case was statistically significant (p=0.014). The
group whose glucose level in blood is more than 150 mg/dl respectively, insulin, c-peptide and cortisol
levels found high and the findings were statistically significant (p<0.001, p=0.005, p=0.040).
Conclusion: Stress hyperglycemia is a common situation seen in critically ill patients as a cause of
worse clinical outcomes. Identification of stress hyperglycemia due to thiamine deficiency is difficult but
it will shed light on the treatment of critically ill children.

Authors: Toledo Toledo Bernarda
Published: July 2020

En este artículo se formula una reflexión acerca del reconocimiento de la importancia de incorporar explícitamente el tema de las emociones en los ambientes donde se educan niñas, niños y jóvenes, de manera que los procesos formativos en la escuela sean instancias significativas que respondan a la comprensión del sentido de la integralidad humana, tanto del sujeto que aprende como del que enseña. Se propone hacerlo profundizando en las capacidades de escucha, confianza y la emoción de la alegría. Una parte importante de este trabajo se nutre de los referentes conceptuales de una tesis doctoral, un estudio hermenéutico que indaga en el lenguaje de las emociones en profesores de cuatro universidades chilenas.
catequesis narrativa: una aproximación fundamentadora y programática
Authors: Siciliani José María
Published: July 2020

Este artículo de reflexión presenta una propuesta de catequesis narrativa. Lo hace en dos apartados: la fundamentación y la pedagogía. El primero estudia cuatro dimensiones vertebradoras de la propuesta: teológico-bíblica, eclesial, personal y social. Se evidencia así el sólido fundamento teológico de este estilo catequético-narrativo, eliminando cualquier percepción según la cual se trataría de una moda pasajera de la catequesis contemporánea. El segundo apartado desarrolla las claves pedagógicas de la propuesta. Hace ver la centralidad de los relatos bíblicos en el acto catequético, las estrategias pedagógicas para trabajarlos en las sesiones de catequesis y la manera de articularlos con la trayectoria biográfica de cada catequizado(a), con la historia de la Iglesia y con la historia de la sociedad.
A Novel Approach to Implementation of Lighting Design Using Virtual Reality
Authors: Babu Akshay , ponthokkan Sharon Joseph , Joseph Aleena , Prasad Abhijith R , VS Aswathy
Published: July 2020

Architectural lighting style may be field among design, interior style and electrical engineering that’s involved with the look of light system as well as natural light-weight, electric-light bulb, or each to serve human wants . Lighting design using virtual reality is an innovative approach towards electrical system design. The lighting design process and the current problems associated with them are solved by integrating two different branches of engineering along with electrical engineering. The problems associated with current lighting design such as excess illumination, improper arrangement and non uniformity can lead to several problems. This includes energy loss, cost overruns and eye strain. Implementation of lighting design using virtual reality helps to overcome many of these problems. It enable the identification of problems in the early stage of design itself by creating a 3D model of the proposed building and transforming it to a real time visual experience with the help of virtual reality concept. Hence the proper lighting calculation along with this will improve overall lighting design in terms of energy savings, cost ,and aesthetics.

Published: July 2020

Electronic Medical Records (EMR) refers to a set of computerized interrelated components that enable data collection, storage, and transformation, aggregate and disseminate information about a patient or a client in a health facility. However, EMR Assessment by Kenya National Aids Control Program (NASCOP) and Division of Health Information System, done earlier identified various EMR systems and other software that are supporting the provision of health care in the country. These software were grouped as; Patient Management Software(e.g.,, C-PADComprehensive Patient Application Data base, OpenMRS-Open Medical Records Software, IQ-CARE and EDPMS), Hospital HMIS Software /ERP Systems, Data Collection and Reporting Software( e.g., C-PAD, OpenMRS, IQ-CARE, EPI-INFO), Data Analysis Software (Kang’a et. al., 2017). This study sought to examine Electronic Medical Records software types in use within Kisumu County. The target population was 525 EMR staff from 7 Sub Counties (clusters) and a sample size of 227 (apportioned to three Sub Counties selected purposively). However, the research intended to reach a sample size of 227 respondents; only 163 out of 227 (72%) questionnaires were received from EMR software users. Data was collected using questionnaires. Descriptive statistics was used to analyze data using Statistical Package for Social Scientist version 22.0.

Published: August 2020

This work was inspired by the growing international interest in the study of natural products of plant origin with bioactive properties that can replace synthetic chemical pesticides in the control of pathogens. The aim of this study was to explore the in vitro activity of Lanvandula dentata L. essential oil (EO) on Fusarium oxysporum f. sp. radicis-lycopersici (FORL), a dangerous fungal plant pathogen, causal agent of tomato crown and root rot. Initially, we proceeded to identify the forma specialis of two strains of F. oxysporum by PCR based on the differences in the genes responsible for the synthesis of endo-polygalacturonases (pg1) and exo-polygalacturonases (pgx4) and then tested the activity of the EO on these strains by the direct contact method at different concentrations. The results showed that increasing the concentration of EO had a significant inhibitory effect, with a minimum inhibition rate of 49.3±2.2 % and 21.8±4.2 for the strains IB19501 and IB19502 respectively at the 0.25 μL/mL concentration and reaching 100±0.0 at the 1 μL/mL concentration for both strains. The data of this study reveal an important anti-fungal activity of the EO of L. dentata, these effects further validate the interest of our study and the traditional use of this plant, while indicating the possibilities of its potential use as a natural alternative to pesticides for the control of pathogenic fungi and thus preserve human health and the environment.
Ion-scale Current Structures in Short Large-amplitude Magnetic Structures
Authors: Wang Shan , Chen Li-Jen , Bessho Naoki , Hesse Michael , Wilson Lynn B. , Denton Richard , Ng Jonathan , Giles Barbara , Torbert Roy , Burch James
Published: July 2020

We investigate electric current structures in Short Large-Amplitude Magnetic Structures (SLAMS) in the terrestrial ion foreshock region observed by the Magnetospheric Multiscale mission. The structures with intense currents (

) have scale lengths comparable to the local ion inertial length (d
i). One current structure type is a current sheet due to the magnetic field rotation of the SLAMS, and a subset of these current sheets can exhibit reconnection features including the electron outflow jet and X-line-type magnetic topology. The d
i-scale current sheet near the edge of a SLAMS propagates much more slowly than the overall SLAMS, suggesting that it may result from compression. The current structures also exist as magnetosonic whistler waves with f
ci < f < f
lh, where f
ci and f
lh are the ion cyclotron frequency and the lower-hybrid frequency, respectively. The field rotations in the current sheets and whistler waves generate comparable

and energy conversion rates. Electron heating is clearly observed in one whistler packet embedded in a larger-scale current sheet of the SLAMS, where the parallel electric field and the curvature drift opposite to the electric field energize electrons. The results give insight about the thin current structure generation and energy conversion at thin current structures in the shock transition region.

Published: July 2020

This study summarises the diversity of living macroinvertebrates and seaweeds from the intertidal and subtidal rocky shores along Ecuadorian continental coast. Benthic macroinvertebrate communities and seaweeds were quantified over quadrants (50 × 50 cm) randomly placed on transects of 50 m length. A checklist of 612 species was generated: 479 species of macroinvertebrates and 133 species of seaweeds. Groups recorded were Mollusca (184 species), Cnidaria (70), Arthropoda (68), Annelida (60), Echinodermata (42), Chordata (18), Bryozoa (13), Porifera (22), Sipuncula (2), Brachiopoda and Platyhelminthes (only identified as morphotypes). The seaweeds were represented by Rhodophyta (78), Chlorophyta (37), Ochrophyta (13), Cyanobacteria (5) and 19 biotic complexes. Furthermore, 22 new taxa and six alien species were recorded from the intertidal zone. This study provides the first large scale report of benthic communities in different marine coastal ecosystems in mainland Ecuador, covering 1,478 km2 of protected areas and 382 km2 of non-protected areas. The highest benthic diversity was registered in the protected areas and rocky shores from the intertidal zone. The biological data, herein reported, are useful for a long-term monitoring programme to evaluate the status of conservation and to detect rapid changes in the benthic biodiversity from coastal areas.
Primary Pancreatic Diffuse Large B-Cell Lymphoma Involving the Stomach
Authors: Park Ji Young , Jeon Tae Joo
Published: August 2020

Primary pancreatic lymphoma (PPL) is extremely rare, comprising fewer than 1% of non-Hodgkin lymphomas. The most common histological subtype of PPL is diffuse large Bcell lymphoma (DLBCL). A 46-year-old man presented with indigestion, epigastric pain, and weight loss for 2 months. Abdominal computed tomography showed a well-defined hypodense mass located at the pancreas head involving the stomach, as well as enlargement of several mesenteric and perigastric lymph nodes. Histological examination was performed by upper gastrointestinal endoscopy of the stomach and endoscopic ultrasound-guided fine-needle aspiration and biopsy of the pancreatic mass. Histology of the pancreatic mass and the stomach revealed pancreatic DLBCL, involving the stomach. The patient received chemotherapy and is currently in complete remission. We report a rare presentation of DLBCL, appearing as a primary pancreatic tumor involving the stomach, which we presume is the first such report in South Korea.

Authors: Roche Cathy C. , Jennings Matthew , Wingo Nancy P.
Published: July 2020

Nurse educators frequently strive to collaborate and share innovative teaching ideas. Finding dedicated time to discuss ways to improve teaching by engaging students is often difficult. Faculty at one university discovered a way to use a new space in an addition to the school of nursing. Faculty meet monthly for “Coffee in the Collaboratory” to share, test, and develop teaching strategies for face-to-face and distance accessible courses. During the meetings, faculty embrace opportunities to practice using new technology. Icebreakers and student-centered learning activities are demonstrated and tested. Faculty take turns sharing how new ideas might be incorporated into both undergraduate and graduate programs. Discussions are spontaneous and fun in this relaxed and friendly environment. A “Coffee in the Collaboratory” meeting can be beneficial in both academic and clinical settings by providing time and space for nurse educators to get together and explore innovative teaching strategies.

Authors: Ridde Valéry , Marie Turcotte-Tremblay Anne
Published: July 2020

Plus de recherches sur la mise en œuvre sont nécessaires pour comprendre comment les interventions fonctionnent dans leur contexte réel et comment elles évoluent dans le temps. L’objectif de ce chapitre est de présenter l’analyse de la mise en œuvre d’une intervention complexe, intitulée le financement basé sur les résultats, au Burkina Faso. Nous avons effectué une étude de cas multiples (18 formations sanitaires) et contrastés avec plusieurs niveaux d’analyse imbriqués. Les données empiriques proviennent d’observations, d’entrevues informelles et formelles et de documents. Pour faciliter l’analyse d’une quantité importante de données, nous avons utilisé un processus pyramidal par lequel chaque membre de l’équipe a analysé et synthétisé des données à un niveau différent (centre de santé, district et général). Ainsi, les assistants de recherche ont participé à l’ensemble du processus d’analyse. L’organisation d’un atelier sur l’utilisation d’un logiciel d’analyse qualitative accessible gratuitement a permis de développer une compréhension commune du processus d’analyse. Les résultats de la recherche montrent l’importance d’ouvrir la « boite noire » pour comprendre la mise en œuvre des interventions de santé publique en Afrique et mettre au jour leurs adaptations selon les contextes et les acteurs et actrices sociaux.
Towards Connected Government Services
Authors: Ramachandran Muthu , Chelliah Pethuru Raj , Soundarabai P. Beaulah
Published: July 2020

Cloud computing technologies are being used highly successfully in large-scale businesses. Therefore, it is useful for governments to adopt cloud-driven multi-channel, and multiple devices to offer their services such as e-tax, e-vote, e-health, etc. Since these applications require open, flexible, interoperable, collaborative, and integrated architecture, service-oriented architecture approach can be usefully adopted to achieve flexibility and multi-platform and multi-channel integration. However, its adoption needs to be systematic, secure, and privacy-driven. In this context, micro services architecture (MSA), a direct offshoot of SOA, is also a highly attractive mechanism for building and deploying enterprise-scale applications. This chapter proposes a systematic framework for cloud e-government services based on the cloud software engineering approach and suggests a cloud adoption model for e-government, leveraging the benefits of MSA patterns. The proposed model is based on a set of evaluated application characteristics that, in turn, support emerging IT-based technologies.
Digital Social Innovation for Better Connected Government

Published: July 2020

Social innovation (SI) refers to new products, processes, and methods that, in a creative and sustainable way, offer a better solution to social demands, which often requires changes in the practices of existing social systems. Digital social innovation (DSI) is ICT-based SI that uses digital technologies to invoke such changes. This chapter presents an insight into DSI in the Republic of Macedonia and reports the results of a survey to show the level of understanding, awareness, and knowledge of DSI in the country. Although the idea of DSI is to bypass the governments, motivate people to self-organize, and solve their societal problems, results suggest that without a good strategy, enough funding, and suitable societal governance, it is difficult to tackle the challenges of raising the awareness of an individual or a community that it is they themselves who are the change-enablers as members of a social network.
Sentiment Analysis in Crisis Situations for Better Connected Government
Authors: López Chau Asdrúbal , Valle-Cruz David , Sandoval-Almazán Rodrigo
Published: July 2020

One of the pillars of connected government is citizen centricity: an approach in which citizen participation is essential. In Mexico, social networks are currently one of the most important means by which citizens express their needs and provide opinions to the government. The goal of this chapter is to contribute to citizen centricity by adapting the methodology of sentiment analysis of social media posts to an expanded version for crisis situations. The main difference in this approach from the normally accepted one is that instead of using pre-defined classes (positive and negative) for sentiments, the authors first determined the different data categories and then applied them to the classic process of sentiment analysis. This approach was tested using posts on Mexico's earthquake in 2017. They found that needs, demands, and claims made in the posts reflect sentiments in a better way, and this can help to improve the government-citizen connection.

Published: July 2020

The growth of the digital ecosystem has given a sense that the rise of security implementations must be considered by every organization including governments in terms of adopting the best digital ethical approaches and awareness on the importance of ensuring privacy. Increased use of the internet has also increased matters of cyber threats and unethical behaviors. Therefore, implementation of digital ethics has become crucial to prevent or minimize the impacts of cybercrime, and so, securing sensitive information from unauthorized access has become extremely important. This study analyses and describes the future trends regarding security in digital ethics and privacy within the digital ecosystem. The results point to a relative correlation between the government and business sector and the types of attacks and that digital ethics and privacy makes up the core elements of security. Implementing cautionary steps are also necessary to prevent from any form of cyber-attack.

When claimed as knowledge-based economic movement, the idea of creative-city is actually part of innovation, because the existence of creative classes are presumed to influence regional economic growth and stimulate as theme of several urban development political choices. Bandung is a city that chooses creative-cities as their political movement, but it gets sharply criticized as like as another creative-cities agenda in the world. This city contains creatively social movements with creative culture in everyday life. By field of capital framework, this article tries to understand how it works in Kampung Kreatif Dago Pojok and Kopi Pasar Los Tjihapit. It is found, both communities use their knowledge as cultural capital to produce spaces creatively with their artistic competence, utilized as nodes to develop networks with other actors to construct their social capital. Their artistic skill is utilized to deliver their cultural dignity, as marginalized urban societies beyond capitalism, to attract attention in urban life. Learning from phenomenology that inserting humanity in science, the creative culture will more meaningful when representing humanity in the innovation of urban development as a part of the cultural sustainability of the society.

Design review is a stage that undertaken to improve the quality of a design in buildings, cities and landscapes. The design review stage can be used to minimize the impact that will occur. Inappropriate design in the planning of the central city of Bandung in Gedebage could have caused the phenomenon of Urban Heat Island (UHI) in the region. The occurrence of this phenomenon can cause the lack of thermal comfort in the area. The potential of Urban Heat Island (UHI) in the planned area can be detected early by conducting design review towards RTBL document of Gedebage Technopolis, Bandung. This study aims to assess the 2014 RTBL of Gedebage with simulation using the ENVI-Met 4.3.1 tool.

Cathode is one of the important parts in performing the high efficiency of proton conducting fuel cell (PCFC). Selection of appropriate cathode material may resolve the major drawbacks at the cathode part associated with the high Rp. Accordingly, tremendous effort have been done to reduce the Rp and one of the alternatives is the modification of cathode microstructure that can be achieved by introducing dispersing agent in the synthesis route. Thus, in this present work, a functionalized carbon nanotubes (f-CNTs) obtained from acidification process was used as a dispersing agent in the synthesis of La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) cathode material. The amount of 4 mg, 8 mg and 12 mg of f-CNTs were respectively added to LSCF cathode during the synthesizing process by a sol-gel method. Semi-solid gel obtained was calcined at 900 °C to form high purity of LSCF powder and respectively denoted as LSCF4, LSCF8 and LSCF12. The powder was characterized by Fourier Transform Infrared (FTIR) Spectroscopy, Pycnometer, Particle Size Analyzer and Scanning Electron Microscopy with Energy Dispersive X-ray (SEM/EDX). The FTIR analysis depicted the peak of respective metal complexes, metal oxide, symmetrical and asymmetrical stretching of carboxylate. The pycnometer showed the lowest density of LSCF4 was 2.8777 g/cm3. The Particles Size Analyzer confirmed the particle size of 38 nm ultrafine powder for LSCF4. The SEM image depicted the highly disperse spherical particles found in LSCF4 with particle size about 30 nm. The elemental composition of the samples is comparable with the nominal stoichiometric of LSCF4 as corroborated by the EDX analysis. Therefore, the LSCF with optimum 4 mg f-CNTs as dispersing agent has potential as nanoporous cathode material for proton conductivity fuel cell.

The activated carbon produced from oil palm empty fruit bunches (ACEFB) shows good properties to act as a dispersing agent in the synthesis of BCZY ceramic material. However, the untreated ACEFB (u-ACEFB) shows some impurities still present after calcination. Thus, it has to be functionalized (f-ACEFB) by using chemical treatment. In this work, three samples of bare BCZY, BCZY u-ACEFB and BCZY f-ACEFB were prepared, respectively. The sol-gel method was used to synthesize the BCZY ceramic powder by using metal nitrate salt as a starting material. The ACEFB was added to the metal precursor accordingly and was dried (T=325°C) followed by calcined (T=1100°C). For the fabrication of pellet, the sample was sintered by two-step sintering (TSS) method. The relative density of pellet was measured and calculated. The Fourier Transform Infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX) were conducted to characterize the synthesized BCZY ceramic material. Based on the characterization, BCZY u-ACEFB have the highest relative density among the others, whereas BCZY f-ACEFB have the lowest relative density. The FTIR results further confirmed the presence of the functional groups corresponded to the BCZY. The SEM micrograph shows a spherical structure of BCZY f-ACEFB with grain size around 134 nm. EDX data further confirm the elemental composition of the pellet. It was observed that the f-ACEFB have an outstanding performance as a dispersing agent in BCZY synthesizing route.

Following successful growth of zinc oxide (ZnO) nanorods, a layer of zinc selenide (ZnSe) was electrodeposited onto the nanorods to further enhance its conversion efficiency in the photoelectrochemical (PEC) cell. The electrodeposited ZnSe layer onto the ZnO nanorods was subjected to heat treatment at 200, 250 and 300°C. The prepared films were characterized by X-ray diffractometry (XRD), field emission scanning electron microscopy (FESEM), and ultraviolet-visible spectroscopy (UV-Vis) to investigate the structural, morphological and compositional characteristics. Additionally, PEC conversion generated by the prepared thin films were tested with photocurrent measurements under calibrated visible illumination from a halogen lamp. Based on FESEM analysis, the thickness of ZnO thin film increased with temperature. However, the diameters of the ZnO nanorods were found to be in a decreasing trend upon heat treatment at higher temperature. The electrodeposited ZnSe layer at the potential of -0.7 V for 60 seconds (calcined at 200°C) possessed crystallite size of 20.1 nm. According to UV-Vis analysis, band gap energy measured was 2.8 eV, which is very close to standard ZnSe band gap value (2.7 eV). Additional layer of ZnSe electrodeposited enhanced thin film performance in terms of current density as much as 37.4% while having high photocurrent density of 0.2671 mAcm-2.

Biofouling and biofilms exist as ubiquitous, undesirable accumulation of flora and fauna upon a given substrate when being immersed into an aquatic medium. Therefore, a novel antifouling based materials with the incorporation of nanotechnology has been developed for the prevention of biofouling in its initial stage through photocatalytic treatment. This study investigated the antimicrobial properties of photoactive Cerium (Ce) doped ZnO powder and explores its potential properties for future antifouling application. ZnO nanoparticles was doped with 0.4 mol% Ce was synthesized through the combination of modified citrate gelation technique and solid state sintering. The successful preparation of Ce doped ZnO was confirmed by XRD and SEM. The antimicrobial activity of Ce doped ZnO against E. coli and S. aureus was determined through antibacterial susceptibility test by agar well diffusion method whilst its photocatalytic inactivation efficiency against selected bacteria was analysed through photodegradation testing under UV light irradiation. The findings demonstrated that the synthesized Ce doped ZnO powder exhibited antibacterial effect against Gram-positive bacteria (S. aureus) and excellent photocatalytic efficiency to inactivate both Gram-negative (E. coli) and Gram-positive (S. aureus). 2 g/L of Ce doped ZnO catalyzed the 100% disinfection of both bacteria in 180 min of UV light exposure. Thus, this proved that Ce doped ZnO powder has the potential as efficient antifouling agent.

A micro-perforated panel (MPP) works as a Helmholtz-type resonance absorber formed by an air-gab cavity in order to minimize the reflected sound effectively at a selective resonance frequency. Furthermore, the use of natural fibers as sound absorbing materials recently has attracted more attention because it is completely biodegradable, environmental friendly and more economical. In this paper, the combination of MPP and natural fiber as sound absorptive material is investigated. The MPP is made of a transparent acrylic board with 1.5 mm thickness and backed by a coconut fiber panel. The effect of the fiber panel that inserted in the air-gab cavity to the sound absorption characteristic of a single leaf MPP is observed. Sound absorption coefficient is measured by transfer function method using two microphones-impedance tube. It is found that the sandwich model of MPP backed by a coconut fiber changes the sound absorption characteristics of MPP by shifting the maximum absorption coefficient into the lower frequency and making a wider band of frequency absorption. Moreover, the air-gab cavity between MPP and fiber panel give fewer contribution to construct the MPP frequency resonant than the natural fiber panel one.

The effects of Ni0.5Zn0.5Fe2O4 nanoparticle addition on the superconducting and transport properties of (Tl0.85Cr0.15)Sr2CaCu2O7 (Tl-1212) superconductor were investigated in this paper. The Tl-1212 samples were produced by mixing high purity oxide powders through a solid-state reaction method. Nano Ni0.5Zn0.5Fe2O4 particles with compositions of 0.001 wt.%, 0.003 wt.%, 0.005 wt.%, 0.01 wt.% and 0.02wt.% with average size of 60 nm were added into the Tl-1212 powders. The transition temperatures (Tc-zero and Tc-onset) were measured using a four-point probe method. The highest Tc-zero recorded was 97 K which was exhibited by the pure Tl-1212 sample. The transport critical current, Ic, of the Tl-1212 samples were found through the 1 µV/cm criterion with temperature ranging from 30 K to 77 K. The sample with a composition of 0.003 wt.% displayed the highest value of Jc at 77 K with a value ranging up to 1780 mA/cm2. The Tl-1212 samples were characterised using scanning electron microscopy (SEM), powder X-ray diffraction method (XRD), energy dispersive X-Ray analysis (EDX), electrical resistance measurements and transport critical current density measurements. The Jc of the Tl-1212 superconductor has been improved through the addition of Ni0.5Zn0.5Fe2O4 nanoparticles but adding an excessive amount has caused its Jc to degrade.
