Authors: Jaafar Mohd Faizal Md. , Muthusamy Khairunisa , Jamaludin Nur Farah Aziera , Jasni Sofia Adibah , Zulkarnain Fahrizal
Published: May 2024

Introduction

The escalating demand for concrete, driven by global infrastructure development, poses significant challenges to environmental sustainability due to the depletion of natural resources and the accumulation of waste materials. This paper explores the potential of utilizing waste materials, particularly palm oil clinker (POC) and spent garnets, as sustainable alternatives in concrete production. The depletion of natural aggregates, such as river sand, coupled with the environmental hazards associated with waste disposal, underscores the urgent need for eco-friendly solutions in construction materials. POC, derived from palm oil production waste, and spent garnets from abrasive industries offer promising avenues for reducing environmental impact and enhancing sustainability in concrete production. By addressing the dual challenges of resource depletion and waste management, this research aims to contribute to developing greener construction practices and mitigating environmental degradation.

Aims

This study aims to investigate the effects of incorporating spent garnet as a partial fine aggregate replacement on the fire resistance of POC LWAC. By examining the interplay between spent garnet inclusion and fire resistance, the research contributes to developing more sustainable concrete formulations and aids in industrial waste management practices, addressing critical societal and environmental challenges.

Methods

This study investigates the effects of elevated temperatures on the compressive strength and durability of POC LWAC specimens. Concrete specimens were demoulded after 24 hours of curing and submerged in water for 28 days. Compressive strength and water absorption tests were conducted at the end of the curing period. Subsequently, specimens were subjected to temperatures of 300 °C, 500 °C, and 700 °C for 1 hour in a furnace. After cooling naturally for 24 hours, visual inspection, mass reduction analysis, and evaluation of residual compressive strength were performed.

Results

Results indicate that 20% garnet replacement yields the highest compressive strength due to pore filling and denser structure. Higher garnet levels lead to reduced strength and increased water absorption. Visual assessment post-heating shows surface alterations, with 20% garnet exhibiting the lowest mass loss and strength reduction at elevated temperatures.

Conclusion

Notably, specimens containing 20% spent garnet in POC LWAC performed better in a fire than others, enhancing their fire-resistant properties. In summary, this research introduces a hopeful approach to improve the sustainability of concrete and mitigate the environmental repercussions of industrial waste.

Authors: Lin Chao , Zhang Xiaoqin , Sun Piliang , liu Shuang , Mao Jiale , Lei Houxing , Ma Yihan , Xu Wenzheng , Pan Fengjun , Chen Meiping
Published: May 2024

Background:

Actinidia eriantha Benth is a widely used natural product from Traditional
Chinese Medicine in the Actinidiaceae family. However, its wild resources have been declining due
to over-exploitation. It has become urgent to investigate the genetic diversity for the conservation of
A. eriantha, to evaluate the current species and discover strategies for preservation.

Methods:

The internal transcribed spacer (ITS) was used to evaluate the genetic diversity among and
within populations of this species. Dnasp, PERMUT and Arlequin 3.0 software were used to calculate the genetic diversity index, and MEGA 5.0 software was used to construct the neighbor-joining
(NJ) tree.

Results:

A total of 27 haplotypes were obtained by ITS sequence analysis of 12 populations, and the
most frequently haplotype observed was H1. AMOVA analysis revealed that the genetic variation
rates were 10.91% (FST = 0.22290) and 77.71% (FSC = 0.12306) among and within populations,
respectively, with high genetic diversity at the species level (Hd = 0.692). The genetic distance
among populations ranged from 0 to 0.004. The results of Permut analysis showed that there was no
significant correlation between genetic distance and geographic distance (NST > GST). The NJ tree
was divided into two Clades (Clade A and Clade B), Clade B has obvious geographical specificity,
and haplotypes of this clade are all specific to the GX-ZY population. Four types were found according
to ITS sequences of A. eriantha, haplotypes H1 and H5 were ancient haplotypes.

Conclusion:

Our findings indicated that genetic diversity within populations was higher than observed among populations. This study is significant for further research endeavors focused on the
efficient collection and preservation of wild resources of A. eriantha.

Published: May 2024

Background:

In this article, an IOT solution for managing and controlling a PV system with
applications for the home is presented. A DC-DC SEPIC converter, a bidirectional converter, a PWM
generator, and a single-phase voltage source inverter with active clamping are used for power conditioning. An output voltage control loop is implemented, and real-time online communication with an internet server is accomplished using the PIC microcontroller.

Methods:

The ESP8266MOD WIFI IOT module works with the Blynk mobile app. Experimental findings showing the proper operation of IOT features demonstrate the effectiveness of voltage regulation.
In this article, frequency is taken into consideration as solar power is integrated with the grid. A user
may easily control the DC-DC converter, load batteries, and monitor battery voltage through our userfriendly GUI interface.

Results:

In this paper, an IOT (Internet of Things) application was used to control and track the output
of a modest PV power plant. The study shows the efficiency of the digitally controlled system developed to regulate the output voltage of the SEPIC DC-DC converter.

Practical Significance:

They further argue that the ESP8266 and microcontroller's versatility make
them an appropriate instrument for remote and real-time monitoring and control of the proposed model
from around the world. The energy that is produced by the sun is added to the grid so that it may be put
to effective use and contribute to satisfying the rising demand for energy. Solar energy is the input that
SEPIC uses to charge the batteries and for all of its other processes. In the event that solar photovoltaic

Authors: Dharmasamitha Indira , Mas Rusyati Luh Made , Wati Dyah Kanya , Gelgel  Wirasuta I. Made Agus
Published: May 2024

Background:

Andrographolide (AP), a bioactive anti-inflammatory compound of Sambiloto,
inhibits NF-κB, TNF-α, and interleukin IL-6. Nowadays, molecular docking simulation between
AP and dexamethasone against NF-κB receptor presented the energy AP higher than dexamethasone.
This becomes a potential treatment for psoriasis.

Objective:

This manuscript reported the effectiveness of AP from Sambiloto in treating psoriasis
compared to topical steroids.

Methods:

This study conducted TLC analysis of AP content and its metabolite impurities, emulgel
formulation, molecular docking, in-silico skin toxicity study, and in-vivo anti-psoriatic activity.
This was a combination study of an in-silico study and an in-vivo study. This in-silico study
was analyzed through multivariate statistical analysis (PCA) to elucidate the data constellation relationship
of andrographolide derivatives with several target proteins. The intervention was performed
in seven days. The PASI score, molecular parameters (IL-6, IL-17, VEGF, and TNF-a levels),
and histopathological findings were assessed.

Results:

Molecular docking results revealed andrographolide to exhibit a relatively high binding
affinity towards IL-6, NF-kB, and TNF-α which is comparable to the corticosteroids, andrographolide
also shares similar residue interaction profile with each of the respective protein’s native
ligand. In the in-vivo study, we found several parameters statistically significantly different regarding
the intervention, including final PASI score (p = 0.017), redness (p = 0.017), scale (p =
0.040), thickness (p = 0.023), total histopathology of psoriasis score (p = 0.037), keratin layer
score (p = 0.018).

Conclusion:

Emulgel AP 0.1% could lower the anti-inflammatory agent, which is vital to psoriasis
progression.

Meaning Giving Material through Artistic Practice
Authors: Md Arif Mohd Fuad , Lugimanif Farah’Aini
Published: May 2024

The position of material engagement within the artistic practice differs from that of scientific practice, be it ontologically or methodologically. In art, the relationship with various types of material could be a physical sensory and bodily touch or towards conceptual undertaking that references philosophical, spiritual, (quasi) scientific, historical, and illogical ideals, venturing into unknown territories that are mysterious, self-discovery, poetic and humorist which can become confrontational towards how we perceive reality. This paper will define and defend how materials are engaged in the artistic practice by giving a phenomenological sample, illustrating how linguistically, material could be understood as a lived-experience.

Use of Multiple-Choice Items in Summative Examinations: Questionnaire Survey Among German Undergraduate Dental Training Programs
Authors: Rössler Lena , Herrmann Manfred , Wiegand Annette , Kanzow Philipp
Published: May 2024

Background

Multiple-choice examinations are frequently used in German dental schools. However, details regarding the used item types and applied scoring methods are lacking.

Objective

This study aims to gain insight into the current use of multiple-choice items (ie, questions) in summative examinations in German undergraduate dental training programs.

Methods

A paper-based 10-item questionnaire regarding the used assessment methods, multiple-choice item types, and applied scoring methods was designed. The pilot-tested questionnaire was mailed to the deans of studies and to the heads of the Department of Operative/Restorative Dentistry at all 30 dental schools in Germany in February 2023. Statistical analysis was performed using the Fisher exact test (P<.05).

Results

The response rate amounted to 90% (27/30 dental schools). All respondent dental schools used multiple-choice examinations for summative assessments. Examinations were delivered electronically by 70% (19/27) of the dental schools. Almost all dental schools used single-choice Type A items (24/27, 89%), which accounted for the largest number of items in approximately half of the dental schools (13/27, 48%). Further item types (eg, conventional multiple-select items, Multiple-True-False, and Pick-N) were only used by fewer dental schools (≤67%, up to 18 out of 27 dental schools). For the multiple-select item types, the applied scoring methods varied considerably (ie, awarding [intermediate] partial credit and requirements for partial credit). Dental schools with the possibility of electronic examinations used multiple-select items slightly more often (14/19, 74% vs 4/8, 50%). However, this difference was statistically not significant (P=.38). Dental schools used items either individually or as key feature problems consisting of a clinical case scenario followed by a number of items focusing on critical treatment steps (15/27, 56%). Not a single school used alternative testing methods (eg, answer-until-correct). A formal item review process was established at about half of the dental schools (15/27, 56%).

Conclusions

Summative assessment methods among German dental schools vary widely. Especially, a large variability regarding the use and scoring of multiple-select multiple-choice items was found.

Taking the attitude system of Martin’s Appraisal Theory as the theoretical framework, this study collects news reports on the 28th UN Climate Change Conference of the Parties from China Daily as the corpus. Through qualitative and quantitative analysis of the corpus, this study explores the distribution pattern and realization of attitudinal resources in these news reports, aiming to reveal the attitude and stance of China Daily towards COP28. According to the study, attitudinal resources consist mostly of appreciation resources, which comprise over half of the total. Affect and judgement resources follow, with a greater proportion of positive than negative resources. Additionally, China Daily frequently adopts a positive viewpoint regarding COP28 through the use of attitudinal materials. This research aids in the efficient comprehension and expression of attitudes and positions in discourses.
Linguistic Trends in Doctor-Patient Communication
Authors: Geethi Ramya
Published: May 2024

Effective communication between doctors and patients is vital for successful consultations. Language plays a key role in making the communication between the doctor and the patient effective. Discourse studies that study language at its micro, as well as at its macro level, provide valuable insights into medical consultations. The objective of the present study is to provide an overview of various linguistic trends that emerged over time to examine talk in doctor-patient consultations. Studies examining doctor-patient discourse have been grouped under Interaction Analysis system, Rhetorical Genre Studies, Conversation analysis, sociolinguistics, Pragmatics, Ethnography, and Systemic Functional Linguistics. It was observed that the linguistic trends that emerged in other contexts were rarely applied to Indian medical consultations. Therefore, there is a need to study Indian doctor-patient consultations using discourse frameworks to arrive at findings that may be used to promote effective communication between the participants.
Self-Discovery in Small Remedies: A Reading of Shashi Deshpande’s
Authors: Kalpana T.

Tombeau idéal de Ferdinand Cheval
Authors: Froment Aurelien
Published: May 2024

The output is an installation comprised of a group of 90 black and white photographs. The subject of the work was Postman Cheval’s Idéal Palace, a monument built by Ferdinand Cheval in Hauterives, France, between 1879 and 1912. Through a selection of natural, cultural, architectural and institutional motifs, the installation displayed the monument’s myriad of forms and translated its ‘architecture of images’ into an exhibition form. Cheval drew upon imagery assembled in world expositions and reproduced as printed matter. Froment’s method reversed Cheval’s process, reconverting sculptural forms into visual images, as though visually dismantling the building piece by piece. The vast ensemble of photographs in turn created an environment of its own, providing the viewer with a stage from which to re-imagine the monument. Conceived as a large photographic survey, production took place over two years. The research was supported, produced and shown internationally between 2014 and 2017. It has been presented in 4 international solo exhibitions and 2 group exhibitions. Total audience figures are in excess of 700,000.

El estándar ISO/IEC 27001 es uno de los estándares en seguridad de la información que más se utiliza en las organizaciones debido a que proporciona un marco de trabajo para la adopción de un sistema de gestión de seguridad de la información. Este estándar indica los requerimientos mínimos para establecer, implementar, mantener y mejorar los procesos, actividades, funciones, infraestructura, roles organizacionales, activos y todos aquellos elementos que forman parte del sistema de gestión de seguridad de la información. En el área universitaria que recientemente se recertificó con éxito en el estándar ISO/IEC 27001, se implementó una metodología que consistió en alinear las siete cláusulas del estándar en las cuatro fases del ciclo de mejora continua y ser ejecutadas en ese orden. Las cláusulas de contexto de la organización, liderazgo, planeación y soporte forman parte de la fase del ciclo de mejora continua denominada como Plan; la cláusula operación en la fase de Hacer; a la fase de Verificación le corresponde la cláusula de evaluación del desempeño y finalmente, en la fase de Actuar se identifica la cláusula de mejora. El apoyo de la alta dirección es fundamental para conseguir buenos resultados en la implementación del Sistema de Gestión de Seguridad de la Información (SGSI).
An Experimental Study on Self Compacting Concrete with Partial Replacement of Cement by Silica Fume and Crumb Rubber
Authors: Prasad Chekka Rajendra
Published: May 2024

Abstract: Self-compacting concrete (SCC) is a type of concrete that can flow and consolidate under its own weight without the need for vibration. SCC has many advantages such as improved workability, durability, surface quality, and reduced noise and labour. However, SCC also requires a high amount of cement and fine materials, which increases the cost and environmental impact of concrete production. Therefore, the use of supplementary cementitious materials such as silica fume and crumb rubber is beneficial to reduce the cement content and enhance the properties of SCC. This study aims to explore the effects of mixing silica fume and crumb rubber on the fresh and hardened properties of SCC. This involves the preparation of various concrete mixes with different percentages of cement replaced by silica fume and crumb rubber. Through a series of experiments, we evaluate the fresh and hardened properties of the SCC mixes, fresh properties such as workability, passing ability, and filling ability, while hardened properties including compressive strength, tensile strength, and flexural strength. The result obtained from these tests are compared with conventional concrete of M30 grade od concrete specimens. Hence the use of silica fume and crumb rubber leads to reduction in cement quantity for construction purpose and its use should be promoted for better performance as well as environmental sustainability.
