The paper considers the uncooled photodetectors based on GaInAsSb/GaAlAsSb heterostructures, which can be applied in precision diode laser spectroscopy. The spectral sensitivity range of photodetectors with a photosensitive area diameter of 1.0 mm and 2.0 mm is 1.0 − 2.4 µm. The current monochromatic sensitivity at the wavelength of 2.1 µm has a value of 1.0 A/W without bias. The capacity reaches 375 pF with a photosensitive area diameter of 1.0 mm and 800-5000 pF with 2 mm. The modern gas analyzers based on diode lasers and developed photodetectors for medical screening diagnostics by analyzing the gas compositions of exhaled air, for control of impurity gases in the process of rectification of inorganic hydrides, control of methane leaks in gas pipelines, as well as for registration of exhaust gases of a moving car are presented.
A Data-Driven Algorithm to Recommend Initial Clinical Workup for Outpatient Specialty Referral: Algorithm Development and Validation Using Electronic Health Record Data and Expert Surveys
Authors: Ip Wui , Prahalad Priya , Palma Jonathan , Chen Jonathan H
Published: March 2022

Background

Millions of people have limited access to specialty care. The problem is exacerbated by ineffective specialty visits due to incomplete prereferral workup, leading to delays in diagnosis and treatment. Existing processes to guide prereferral diagnostic workup are labor-intensive (ie, building a consensus guideline between primary care doctors and specialists) and require the availability of the specialists (ie, electronic consultation).

Objective

Using pediatric endocrinology as an example, we develop a recommender algorithm to anticipate patients’ initial workup needs at the time of specialty referral and compare it to a reference benchmark using the most common workup orders. We also evaluate the clinical appropriateness of the algorithm recommendations.

Methods

Electronic health record data were extracted from 3424 pediatric patients with new outpatient endocrinology referrals at an academic institution from 2015 to 2020. Using item co-occurrence statistics, we predicted the initial workup orders that would be entered by specialists and assessed the recommender’s performance in a holdout data set based on what the specialists actually ordered. We surveyed endocrinologists to assess the clinical appropriateness of the predicted orders and to understand the initial workup process.

Results

Specialists (n=12) indicated that <50% of new patient referrals arrive with complete initial workup for common referral reasons. The algorithm achieved an area under the receiver operating characteristic curve of 0.95 (95% CI 0.95-0.96). Compared to a reference benchmark using the most common orders, precision and recall improved from 37% to 48% (P<.001) and from 27% to 39% (P<.001) for the top 4 recommendations, respectively. The top 4 recommendations generated for common referral conditions (abnormal thyroid studies, obesity, amenorrhea) were considered clinically appropriate the majority of the time by specialists surveyed and practice guidelines reviewed.

Conclusions

 An item association–based recommender algorithm can predict appropriate specialists’ workup orders with high discriminatory accuracy. This could support future clinical decision support tools to increase effectiveness and access to specialty referrals. Our study demonstrates important first steps toward a data-driven paradigm for outpatient specialty consultation with a tier of automated recommendations that proactively enable initial workup that would otherwise be delayed by awaiting an in-person visit.
Medical-Blocks―A Platform for Exploration, Management, Analysis, and Sharing of Data in Biomedical Research: System Development and Integration Results
Authors: Valenzuela Waldo , Balsiger Fabian , Wiest Roland , Scheidegger Olivier
Published: March 2022

Background

Biomedical research requires health care institutions to provide sensitive clinical data to leverage data science and artificial intelligence technologies. However, providing researchers access to health care data in a simple and secure manner proves to be challenging for health care institutions.

Objective

This study aims to introduce and describe Medical-Blocks, a platform for exploration, management, analysis, and sharing of data in biomedical research.

Methods

The specification requirements for Medical-Blocks included connection to data sources of health care institutions with an interface for data exploration, management of data in an internal file storage system, data analysis through visualization and classification of data, and data sharing via a file hosting service for collaboration. Medical-Blocks should be simple to use via a web-based user interface and extensible with new functionalities by a modular design via microservices (blocks). The scalability of the platform should be ensured through containerization. Security and legal regulations were considered during development.

Results

Medical-Blocks is a web application that runs in the cloud or as a local instance at a health care institution. Local instances of Medical-Blocks access data sources such as electronic health records and picture archiving and communication system at health care institutions. Researchers and clinicians can explore, manage, and analyze the available data through Medical-Blocks. Data analysis involves the classification of data for metadata extraction and the formation of cohorts. In collaborations, metadata (eg, the number of patients per cohort) or the data alone can be shared through Medical-Blocks locally or via a cloud instance with other researchers and clinicians.

Conclusions

Medical-Blocks facilitates biomedical research by providing a centralized platform to interact with medical data in collaborative research projects. Access to and management of medical data are simplified. Data can be swiftly analyzed to form cohorts for research and be shared among researchers. The modularity of Medical-Blocks makes the platform feasible for biomedical research where heterogeneous medical data are required.

Usability Issues in Evidence-Based Psychosocial Interventions and Implementation Strategies: Cross-project Analysis (Preprint)
Authors: Munson Sean A , Friedman Emily C , Osterhage Katie , Allred Ryan , Pullmann Michael D , Areán Patricia A , Lyon Aaron R ,   UW ALACRITY Center Researchers
Published: March 2022

BACKGROUND

People often prefer evidence-based psychosocial interventions (EBPIs) for mental health care; however, these interventions frequently remain unavailable to people in nonspecialty or integrated settings, such as primary care and schools. Previous research has suggested that usability, a concept from human-centered design, could support an understanding of the barriers to and facilitators of the successful adoption of EBPIs and support the redesign of EBPIs and implementation strategies.

OBJECTIVE

This study aimed to identify and categorize usability issues in EBPIs and their implementation strategies.

METHODS

We adapted a usability issue analysis and reporting format from a human-centered design. A total of 13 projects supported by the National Institute of Mental Health—funded Accelerating the Reach and Impact of Treatments for Youth and Adults with Mental Illness Center at the University of Washington used this format to describe usability issues for EBPIs and implementation strategies with which they were working. Center researchers used iterative affinity diagramming and coding processes to identify usability issue categories. On the basis of these categories and the underlying issues, we propose heuristics for the design or redesign of EBPIs and implementation strategies.

RESULTS

The 13 projects reported a total of 90 usability issues, which we categorized into 12 categories, including complex and/or cognitively overwhelming, required time exceeding available time, incompatibility with interventionist preference or practice, incompatibility with existing workflow, insufficient customization to clients/recipients, intervention buy-in (value), interventionist buy-in (trust), overreliance on technology, requires unavailable infrastructure, inadequate scaffolding for client/recipient, inadequate training and scaffolding for interventionists, and lack of support for necessary communication. These issues range from minor inconveniences that affect a few interventionists or recipients to severe issues that prevent all interventionists or recipients in a setting from completing part or all of the intervention. We propose 12 corresponding heuristics to guide EBPIs and implementation strategy designers in preventing and addressing these usability issues.

CONCLUSIONS

Usability issues were prevalent in the studied EBPIs and implementation strategies. We recommend using the lens of usability evaluation to understand and address barriers to the effective use and reach of EBPIs and implementation strategies.

Authors: Harrison Anna , Folk Joanna , Rodriguez Christopher , Wallace Amanda , Tolou-Shams Marina
Published: March 2022

BACKGROUND

Justice-involved young adults have high rates of substance use disorders. Despite the need for treatment, there are unique challenges to recruiting young adults into substance use treatment trials. Digital health technology offers many novel avenues for 1) recruiting justice-involved young adults into clinical research studies and 2) studying ways to increase access to substance use services for justice-involved young adults.

OBJECTIVE

The current study describes the process and feasibility of recruiting justice-involved young adults into clinical research using social media and the acceptability of digital health interventions to address substance use in this population.

METHODS

Justice-involved young adults (ages 18-24) were recruited through Facebook ($0.66 per click) and Reddit ($0.47 per click) paid advertisements. Participants responded to an online survey focused on their substance use, treatment utilization history, and acceptability of substance-use focused digital health interventions.

RESULTS

A national sample of justice-involved young adults were successfully enrolled and completed the survey (N=131). More than half of participants were on probation or parole in the past year (55%) and reported hazardous alcohol (52%) or drug (57%) use. Most (78%) were not currently participating in substance use treatment. Nearly 2/3 (63%) were willing to participate in one or more hypothetical digital health interventions.

CONCLUSIONS

Social media appears to be a feasible and cost-effective method for reaching justice-involved young adults to participate in substance use research trials. Proposed digital health interventions focusing on reducing substance use had high acceptability

Authors: APRIDAMAYANTI P. , PRATIWI L. , SARI R.
Published: March 2022

Objective: This research aimed to qualitatively determine the chemical compound constituents, antioxidant capacity, and sun protection factor (SPF) value of extract of the leaves of Melastoma malabathricum L. using GC-MS.
Methods: The detected compounds were identified by processing the raw GC-MS data using ChemStation software and comparing results with the NIST mass spectral database. Antioxidant capacity was measured using 1,2-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging and ferric-reducing antioxidant power (FRAP) assays. The SPF contained in the n-hexane and chloroform fractions separated from the ethanol extract of the leaves of Melastoma malabathricum L was identified.
Results: The GC-MS test results revealed that 21 and 29 peaks of separation occurred in the n-hexane and chloroform fractions. The highest peak values are hexadecanoic acid methyl ester (a fatty acid group also known as palmitic acid) (100%) in the n-hexane and chloroform fractions. The highest chemical content in n-hexane and chloroform fractions was obtained at 20 min. The thin-layer chromatography (TLC) results indicated that the n-hexane and chloroform fractions contained steroid and terpenoid compounds. The antioxidant capacity test using DPPH showed that the n-hexane and chloroform fractions of ethanol extract of the leaves of Melastoma malabathricum L had IC50 values ​​of 49.2±7.9 g/ml and 11.3±3.65 g/ml, respectively. Using FRAP, the IC50 values ​​of the n-hexane and chloroform fractions were identified as 365.2±133.6 g/ml and 80.8±8.9 g/ml, respectively, categorizing them as strong and weak antioxidants. SPF testing produced SPF values ​​for the n-hexane and chloroform fractions of ethanol extract of Melastoma malabathricum L leaves of 11.7±0.1 and 21±0.4, respectively.
Conclusion: The study results show that the antioxidant activity and the SPF values of the chloroform fraction are greater than those of the n-hexane fraction. In conclusion, the n-hexane and chloroform fractions are found to have antioxidant properties in the weak and solid categories and the ability to protect against sunlight in the vulnerable category.

Ruskin born in 1819, he studied at seventeen and joined next year Christ College,Oxford, also good gentlemen. He was the foremost English art critic of the Victorian age. Ruskin convicts the science of political Economy as it makes no providing for social cares. Also it bases itself on the theory of utility, and which does not principal to this end and past its influence. It has striking and attractive piece like alchemy, astrology or witchcraft, but its reality is terrible and cold-hearted. The transmission of wealth in a public of nations can be associated to that of blood in the human body. The word discrimination consider as good or bad, depends on manner by which it is established and the purpose for used. Ruskin says from Dante’s “Divine Comedy” means “You judges of the earth”.

Aim:
Streamlining consent for low-risk comparative effectiveness research (CER) could facilitate research, while safeguarding patients' rights.
Materials & methods:
2618 adults were randomized to one of seven consent approaches (six streamlined and one traditional) for a hypothetical, low-risk CER study. A survey measured understanding, voluntariness, and feelings of respect.
Results:
Participants in all arms had a high understanding of the trial and positive attitudes toward the consent interaction. Highest satisfaction was with a streamlined approach showing a video before the medical appointment. Participants in streamlined were more likely to mistakenly think a signature was required.
Conclusion:
Streamlined consent was no less acceptable than traditional, signed consent. Streamlined and traditional approaches achieved similar levels of understanding, voluntariness and a feeling that the doctor–patient interaction was respectful.
Vegetable Grading and Sorting using Artificial Intelligence
Authors: Farooq Omer , Gill Jasmeen
Published: March 2022

Abstract: Agriculture and food industry are the backbone of any country. Food industry is the prime contributor in agricultural sector. Thus, automation of vegetable grading and sorting is the need of the hour. Since, artificial neural networks are best suited for automated pattern recognition problems; they are used as a classification tool for this research. Back propagation is the most important algorithm for training neural networks. But, it easily gets trapped in local minima leading to inaccurate solutions. Therefore, some global search and optimization techniques were required to hybridize with artificial neural networks. One such technique is Genetic algorithms that imitate the principle of natural evolution. So, in this article, a hybrid intelligent system is proposed for vegetable grading and sorting in which artificial neural networks are merged with genetic algorithms. Results show that proposed hybrid model outperformed the existing back propagation based system. Keywords: Vegetable grading and sorting; artificial neural networks; Particle Swarm Optimization; Hybrid intelligent system; Pattern recognition

CICM: A Collaborative Integrity Checking Blockchain Consensus Mechanism for Preserving the Originality of Data the Cloud for Forensic Investigation
Authors: Salami Omoniyi , Abdulrazaq Muhammad Bashir , Adedokun Emmanuel Adewale , Yahaya Basira
Published: March 2022

The originality of data is very important for achieving correct results from forensic analysis of data for resolving the issue. Data may be analysed to resolve disputes or review issues by finding trends in the dataset that can give clues to the cause of the issue. Specially designed foolproof protection for data integrity is required for forensic purposes. Collaborative Integrity Checking Mechanism (CICM), for securing the chain-of-custody of data in a blockchain is proposed in this paper. Existing consensus mechanisms are fault-tolerant, allowing a threshold for faults. CICM avoids faults by using a transparent 100% agreement process for validating the originality of data in a blockchain. A group of agreement actors check and record the original status of data at its time of arrival. Acceptance is based on general agreement by all the participants in the consensus process. The solution was tested against practical byzantine fault tolerant (PBFT), Zyzzyva, and hybrid byzantine fault tolerant (hBFT) mechanisms for efficacy to yield correct results and operational performance costs. Binomial distribution was used to examine the CICM efficacy. CICM recorded zero probability of failure while the benchmarks recorded up to 8.44%. Throughput and latency were used to test its operational performance costs. The hBFT recorded the best performance among the benchmarks. CICM achieved 30.61% higher throughput and 21.47% lower latency than hBFT. In the robustness against faults tests, CICM performed better than hBFT with 16.5% higher throughput and 14.93% lower latency than the hBFT in the worst-case fault scenario.
The Port-Franco of Odessa of the North: Alexander Den’gin’s Development Project of the Mouth of the Pechora River in the 1820s to 1840s
Authors: Komleva Evgeniya V.
Published: March 2022

The article is devoted to a little-known episode in the history of the development of the Russian North, one that is associated with the name of the Vologda merchant Alexander Ivanovich Dengin. The contribution brings together the available biographical information about A.I. Dengin and characterizes his project concerning the economic development of the territory adjacent to the mouth of the Pechora River. This project he elaborated in the 1820s to 1840s; it aimed at the development of both the Pechora Region and Western Siberia by establishing regular water communication between the European and Asian parts of Russia. The article reviews the various stages in the drafting of this document, and traces its way through different instances. Filled with patriotic rhetoric, the source under consideration emphasizes not only Dengins personal interest - to derive material benefits from the exploitation of the Pechora estuary - but also reflects that entrepreneurs were fully aware of the necessity to develop the northern territories in order to integrate these regions fully into the Russian Empire. A close cooperation between state authorities and representatives of private capital was considered an indispensable condition for achieving this goal. A.I. Dengins note also reveals how the Russian merchant class of the pre-Reform period viewed the world. They had a very high opinion of their professional activities, which they thought were indispensable not only for the successful functioning of the economy but also for raising the general level of culture and education among the population. Commerce was seen as the most important means for achieving progress and common welfare.
The Sanitary Service of the 431st Tikhvin Infantry Regiment during World War I
Authors: Bondareva Vera V. , Eilbart Natalia V.
Published: March 2022

The article analyzes the formation and development of the sanitary service in one particular regiment in the period from August 1914 to December 1916. The main body of sources con- sists of archival files of the respective military unit. The novelty of the present paper is seen in the fact that it is the first study devoted to the formation of the medical service of the regiment, starting with the militia squads. It is proved that in the squads the sanitary unit was not independent but relied on the zemstvo medical system of the cities and on the infirmaries of the garrisons. A focus is on the work of doctors in the 431st Tikhvin Regiment during their stay in Livonia from June 1915 to May 1916. Various areas of medical care of the regiment before participating in hostilities are studied in detail: the treatment of soldiers and prophylactic examinations, sanitary education, supervision of places of residence, as well as the prevention of infectious diseases. It is established that during the guard service of the regiment, the sanitary unit worked satisfactorily. The article zooms in on the expansion of the duties of the regiment's sanitary service at the front starting in the summer of 1916, and identifies how the medical personnel of the regiment was replenished. Special attention is paid to the difficult sanitary and hygienic situation at the front in Austria-Hungary, and the measures that were taken to combat the main epidemics that arose at the front, namely typhus, cholera, and dysentery. Equally discussed are the consequences of unsettled life and malnutrition.
NEET youth: Consumer behavior in the new reality
Authors: Bulanova M. B. , Artamonova E. A.
Published: March 2022

The article considers the features of the consumer behavior of the NEET youth. Being a part of the generation Z, this group is known for its refusal to work and study, to look for some forms of employment or training. According to the European statistical data, since 2020, there has been an uneven distribution of NEETs by country, and their average share is 14%. According to the Russian data, in recent years there has been a sharp increase in NEETs share (28%) due to the instability of the labor and education markets under the coronavirus pandemic. In Europe, the majority of NEETs are non-working (unemployed) youth; in Russia, NEETs are mainly economically inactive youth with an inadequate level or quality of training. Despite some difference in the structure of the European and Russian NEETs, their consumer behavior has common features determined by their belonging to the generation Z, whose lifestyle is based on the delay in growing up and on the development of digital space and new technologies. However, unlike other groups of the youth, NEETs do not reduce alcohol consumption, do not choose a healthy lifestyle and do not have a sense of subjective well-being. The authors identify the main strategies of the NEET consumer behavior, and the most common are basic, demonstrative and symbolic consumption mainly supported by parents, state and charity organizations. Under the pandemic, the NEETs attempt to keep habitual life and consumption practices was unsuccessful due to the change in the family and social support. Therefore, the NEET group was forced to leave its social niche, which allowed it to partially restore its social connections.

Authors: Donetskaya S. S. , Bing Wang
Published: March 2022

In the past three decades, the higher education system of China has shown the most dynamic development. One of the reasons is the president responsibility under the leadership of the Party committee, which was introduced in public universities in the early 1990s and corresponds to the national traditions as the fundamental management system in Chinese general universities. Recent changes in the Chinese society and economy have led to the establishment of private and joint universities, which determined transformations of this management system and the development of several university management systems. The article aims at describing the features of the contemporary university management systems of different forms of ownership in China together with their advantages and disadvantages. The article provides a brief review of the history of the development of public university management systems from the founding of the PRC to the present day; explains the main features of the Chinese higher education system and the changes in the number of public, private and joint universities in the past ten years. The authors focus on the management systems of public, private and joint universities to show that the management system of the university of any form of ownership consists of three parts - decision-making, practices and control. The article explains the specifics of relations between the highest governing bodies of the university - party committee, president and governing board (board of directors) - and the real system of relations between the administrative and academic authorities. The article is based on the data of the Chinese Ministry of Education, laws and other regulations of the Chinese government in the higher education, websites of the leading Chinese universities, and publications available on the Chinese Internet.

Authors: Moreno Ricardo
Published: March 2022

Este texto tem como objetivo refletir acerca das disputas simbólicas em torno da memória tomando como base empírica um equipamento cultural do quilombo Machadinha, na cidade de Quissamã, RJ. No momento em que a comunidade vivia um período de tomada de consciência de sua condição quilombola, o referido espaço, denominado Memorial, recebeu um conjunto de objetos vindos de Angola para compor uma cenografia. Os objetos foram trazidos por uma equipe coordenada pela então presidente da Fundação de Cultura, com a intenção de estabelecer uma relação entre os moradores daquela comunidade e uma determinada etnia angolana de uma região chamada kissama. Esta relação está expressa em uma história muito difundida na região acerca da origem do nome da cidade: Quissamã. Para dar conta da parte analítica do trabalho eu mobilizei teóricos da Antropologia e da História que lidam com o tema da memória, tais como Johannes Fabian, Richard Handler, Michael Pollak e Andreas Huyssen.

Published: March 2022

Objective: We aimed to explore the potential mechanism of pelvic lymph
node (pLN) metastasis of cervical cancer (CC) by multiplex
immunofluorescence (mIF) and construct a nomogram for preoperative
prediction of pLN metastasis in patients with CC. Methods: A series of
90 patients with CC (2009 FIGO, IB1-IIA2) was retrospectively assayed
with metastatic pLN or not. Tissue microarray (TMA) were prepared and
tumor-infiltrating immune markers were assessed by mIF. Pearson
correlation coefficients (R), linear regression and spatial proximity
analysis were applied to study the potential mechanism of these markers.
Multivariable logistic regression analysis and nomogram were used to
develop the predicting model. Results: We concluded that T cells may
interact with NK cells and macrophages through PD-1 and PD-L1 to promote
pLN metastasis of CC. Multivariable logistic regression analysis and
nomogram construct a predictive model and area under curve (AUC) can
reach 0.843. By internally validation with the remaining 40 percent of
cases, a new ROC curve was emerged and the AUC reaching 0.888.
Conclusions: This study presents an immune nomogram, which can be
conveniently used to facilitate the preoperative individualized
prediction of LN metastasis in patients with CC. Keywords: cervical
cancer, multiplex immunofluorescence, nomogram, internally validation
Treatment Planning CT Radiomics for Predicting Treatment outcomes and Hematologic Toxicities to Intensity-modulated Radiation Therapy in Locally Advanced Cervical Cancer
Authors: Ren Kang , Shen Lin , Qiu Jianfeng , Sun Kui , Chen Tingyin , Xuan Long , Yang Minwu , She Hao-Yuan , Shen Liangfang , Deng Lan , Jing Di , Shi Liting
Published: March 2022

Objectives: We evaluated radiotherapy planning CT-based radiomics for
predicting clinical endpoints [tumor complete response (CR), 5-year
overall survival (OS), hypohemoglobin, and leucopenia] after
intensity-modulated radiation therapy (IMRT) in locally advanced
cervical cancer (LACC). Methods: This study retrospectively collected
257 LACC patients treated with IMRT from 2014 to 2017. Patients were
allocated into the training/validation sets (3:1 ratio) using
proportional random sampling, resulting in the same proportion of groups
in the two sets. We extracted 254 radiomic features from each of the
gross target volume (GTV), pelvis, and sacral vertebrae in planning CT
images. The sequentially backward elimination support vector machine
algorithm was used for feature selection and endpoint prediction. Model
performance was evaluated using area under the curve (AUC). Results: A
combination of 10 clinicopathological parameters and 34 radiomic
features achieved the best performance for predicting CR [validation
balanced accuracy: 80.79%]. For OS, 54 radiomic features showed good
prediction accuracy [validation balanced accuracy: 85.75%], and the
threshold value of their scores can stratify patients into the low-risk
and high-risk groups (P<0.001). The clinical and radiomic
models were also predictive of hypohemoglobin and severe leucopenia
[validation balanced accuracies: 70.96% and 69.93%]. Conclusion:
This study demonstrated that combining clinicopathological parameters
with CT-based radiomics had good predictive value for treatment outcomes
and hematologic toxicities to radiotherapy in LACC. The prediction of
clinical endpoints prior to radiotherapy may assist the radiation
therapists to select the optimal therapeutic strategy with the minimal
toxicity and best curative effect.
Understanding Manga as a “Style” through Essay Manga’s Multimodal Literacies：And Its Relations to the Discourse on “local art style” in Malaysian Comics
Authors: NASIR Suraya Binti Md
Published: March 2022

The trans-cultural consumption of Japanese Manga in Malaysia has prompted a significant amount of manga-influenced local works. As an outcome, traces of Japanese Manga can be found through its iconic art styles, storytelling and Japanese culture in these works. While fans show the positive response for these manga-influenced local works, the artists’ community shows the opposite response, in particular, related to the representation of the “typical Japanese manga-style”, resulting in the idea that these artists are turning away from the “local art style” which has been pioneered by the predecessors. The sentiment of Japanese Manga as a “single art style” contributed to this misconception on what constitutes a Japanese manga identity. In which the researcher proposes the introduction of ‘Essay Manga’ (コミックエッセイ or エッセイマンガ) as a way to divert the attention of Japanese Manga’s art style, by shifting to the other attributes of Japanese Manga which is the story. Essay Manga is a manga work that describes the events that happened around the manga artist but without any specifications towards manga visual conventions. To illustrate the importance of story versus art style in Essay Manga, the characteristics, forms, examples are sketched out trough the works of Hosokawa Tenten and Azuma Hideo. A section on Malaysia “local art style” is also discussed and ties in with the discussion of Manga. Eventually, the study argues that Japanese Manga is not limited to visual representation; instead, it is accommodated by its engaging storytelling, thus justifying Essay Manga’s potential as a multimodal literacy works.

Addition of poly(diallyldimethylammonium chloride) (PDDA) on the performances of urea-formaldehyde (UF) adhesives was evaluated in this work. Three types of UF adhesives were prepared, one without PDDA addition, and two types with PDDA addition of 1 and 3 wt.% per dry UF adhesive mass. These UF adhesive systems were used for producing experimental particleboard panels. The addition of PDDA decreased the thickness swelling of the panel samples, while the internal bond of the particleboards increased significantly only at the highest PDDA content (3 wt.%). Differential scanning calorimetry (DSC) was applied to address the influence of PDDA on UF adhesive curing kinetics. DSC scans were performed in non-isothermal regimes using different heating rates (5, 10, and 20 ?C?min?1). The activation energy (Ea) of the curing reaction showed slightly lower values for the UF adhesive systems containing PDDA. However, the peak temperatures and enthalpy of reaction did not change significantly. The Kissinger-Akahira-Sunose and Friedman iso-conversional methods were applied to investigate the effects of PDDA addition on the UF adhesive curing process.
