The Aceh BKKBN has promoted the Proud Kencana program, however, until now the public's understanding, especially the youth's knowledge of the Proud Kencana program, is still lacking. This study focuses on the implementation of the policy of promoting the Proud Kencana program through online media for adolescents. The theory used in this research is the theory of Van Meter and Horn, about the factors that influence policy implementation. This research is a qualitative research, with high school youth and college students as informants. The results of the study indicate that the indicators of basic measures and the objectives of promotion policies play a role in communicating what the public needs in changing the mindset of young people in planning their future (education, work and married life) increasing awareness and understanding of adolescents about population issues, maturing age at marriage. , reproduction health. The source of this program's online promotion policy is carried out by 7 main staff and assisted by 82 BKKBN employees. Social and political factors influence the Proud Kencana program. Socially, almost all of them have cellphones, they support providing opportunities for the implementation of Proud Kencana online. On the other hand, the understanding of teenagers in Bangga Kenca is still limited, so that the interest and access of teenagers in Bangga Kencana is not maximized. Political conditions support the promotion of Proud Kencana Social, economic, and political environmental conditions greatly affect, if conditions are not conducive it can cause problems from the failure of policy implementation performance. The implementer is in accordance with the applicable implementation SOP because the standard of a policy is measured by the extent of planning to the involvement of various competent parties from the beginning of policy formulation to the policy evaluation stage.

Published: August 2022

In the present paper, we classify all normalized null hypersurfaces $x: (M,g,N)\to\R^{n+2}_1$ endowed with UCC-normalization with vanishing $1-$form $\tau$, satisfying $L_r x =U x +b$ for some (field of) screen constant matrix $U\in \R^{(n+2)\times(n+2)}$ and vector$b\in\R^{n+2}_{1}$, where $L_r$ is the linearized operator of the$(r+1)th-$mean curvature of the normalized null hypersurface for$r=0,...,n$. For $r=0$, $L_0=\Delta^\eta$ is nothing but the (pseudo-)Laplacian operator on $(M, g, N)$. We prove that the lightcone $\Lambda_0^{n+1}$, lightcone cylinders $\Lambda_0^{m+1}\times\R^{n-m}$, $1\leq m\leq n-1$ and $(r+1)-$maximal Monge null hypersurfaces are the only UCC-normalized Monge null hypersurface with vanishing normalization $1-$form $\tau$ satisfying the above equation. In case $U$ is the (field of) scalar matrix $ \lambda I$, $\lambda\in\R$ and hence is constant on the whole $M$, we show that the only normalized Monge null hypersurfaces $x: (M,g,N)\to\R^{n+2}_1$ satisfying $\Delta^\eta x =\lambda x +b$, are open pieces of hyperplanes.

Published: August 2022

Silica is the most reinforcing filler for enhancing the rubber properties. However, the incompatibility of silica with non-polar rubber is the main problem for application. Therefore, the researchers attempted to use the several methods in order to solve the problem. In this work, the appropriated hydroxyl telechelic natural rubber (HTNR) was determined by varying molecular weights in the range of 2,000-3,000 gÂ·mol-1 and contents in the range of 4-16%w/w of silica content in order to enhance the rubber properties. It was found that the decrease in Payne effect and the improvement in cure characteristics of silica-reinforced NR were achieved by using HTNR. However, the incorporation of various molecular weights and contents of HTNR in rubber influenced C1 (crosslink density determined by stress-strain measurement) in rubber, which related to rubber properties. The increasing in C1 caused the increases in tensile strength and abrasion index and the decrease in heat build-up. The optimum properties of rubber with silica loading at 30 phr was achieved by adding 2,000 gÂ·mol-1 HTNR at a loading of 8%w/w of silica content. However, for silica-reinforced NR, TESPT provided better properties than HTNRs.

Authors: Jiarawattananon Mateekul , Wasanapiarnpong Thanakorn , Mongkolkachit Charusporn
Published: August 2022

This study presents a ceramic tile preparation to effectively utilize lignite bottom ash as one of raw materials. Bottom ash in the mixtures was varied in the range of 40-50 wt%. The milled raw materials were pressed at the pressure of 30 MPa to form 2Ã—4 inch ceramic tiles. The samples were dried and tested for modulus of rupture in order to observe their green strength. Then, the samples were fired at 1150-1200Â°C. The sintered samples were investigated in terms of modulus of rupture (MOR), water absorption (WA) and phase composition. Tiles are classified according to their water absorption and modulus of rupture into 3 groups by following Thai Industrial Standards of ceramics tiles (TIS 2508-2555). The suitable dry strength of tiles were made from lignite bottom ash 50 wt%, Mae Tan clay 40 wt% and Lampang clay 10 wt% were obtained at 110Â°C is 2.82 MPa. Tiles were classified to group 2 after firing at 1150Â°C (WA = 7.03%, MOR = 32.48 MPa) and 1175Â°C (WA = 6.22%, MOR = 34.21 MPa) and group 1 after firing at 1200Â°C (WA = 0.72%, MOR = 34.51 MPa). This formula can be applied to both floor tile and wall tile production.

Published: August 2022

Around 3 million tons of municipal solid wastes called bottom ash (BA) are produced annually from the coal-fired power plants and it is still much underutilized in Thailand.Â  Hence, the increasing usage of BA in industrial scale is necessary to limit the environmental impacts from landfilling of those by-product. Using of BA in fiber cement (FC) manufacturing seems to be a promising one.Â  However, several negative effects regarding the extremely high water content from the fiber-cement forming process (Hatschek process) and the BA characteristic (the creation of bubble network) need to be eliminated.Â  Both mentioned inferiors significantly reduce the cement hydration mechanism leading to remarkable reductions of set and hardened performances of fiber cement.Â  Therefore, chemical treatment (CT) was introduced to boost up the hydration kinetic and characterized via the relevance of higher heat of hydration.Â  Additionally, scanning electron microscope (SEM) was used to reveal the beneficial effects of treated BA through the microstructures. The results showed the chemically treated BA improve kinetic of hydration reaction was from the modification of BA surface.
Study on mechanical and viscoelastic behavior of carbon nanotube (CNT) reinforced Epofine1564 nanocomposite
Authors: Kumar Puneet , Srinivas Jonnalagadda
Published: August 2022

This paper presents an experimental study to examine the mechanical and viscoelastic characteristics of multi-walled carbon nanotubes (MWCNTs) reinforced epoxy nanocomposite. The nanocomposite samples of varying volume fractions are prepared using solution mixing technique. A two-step mixing procedure with magnetic stir and bath type ultra sonicator is employed to acquire well dispersion of CNTs in epoxy resin. Three-point bending, tensile and impact tests are conducted on the prepared samples to measure the elastic modulus, strength and failure strain respectively. The morphological analysis of fractured samples is carried-out under field emission scanning electron microscopy (FESEM). The dispersion and reinforcing mechanism of CNTs within the polymer matrix are observed. The results show that a small amount of CNTs in a polymer matrix improves the stiffness and strength of the composite considerably. The agglomeration occurs beyond the 0.5 wt% of CNTs. Furthermore, towards thermal stability analysis, the improvement of viscoelastic characteristics with the addition of MWCNTs is studied using dynamic mechanical analysis test. Results are shown in the form of graphs and tables.

Authors: Le Xuan Vuong , Duong Vu Truong , Luu THI Lan Anh , Pham Van Thang , Nguyen Huu Lam , Nguyen Cong Tu
Published: August 2022

WO3 nanoplate synthesized by acid precipitation method was composited with commercial carbon nanotube with different weight percents (0.5, 1.0, and 1.5 wt% of CNT). The ammonia gas sensing characteristics of composite materials at low temperature (50Â°C) were investigated and compared with that of pristine materials (WO3 nanoplate, commercial carbon nanotube). The results showed that the composition enhanced the gas sensing properties in comparison with the pristine carbon nanotube-based sensor and more stable than pristine WO3 nanoplate-based sensor. The response of gas sensors to 30 ppm of ammonia got the highest value of 45% in 0.5 wt%-CNT sensor â€“ enhanced 100 times in comparison with carbon nanotube-based sensor. The calculated limit of detection of 0.5 wt%CNT/WO3 sensor was at sub-trace-level of 3 ppb. This enhancement shows the high applicability of composite materials in gas sensor working at room temperature.

Published: August 2022

Nano-CaCO3 (NCC) obtained from Achatina achatina shells were used as single filler and as partial replacement of carbon black (CB) to produce vulcanized natural rubber (NR) filled at 5, 10, 15, 20, 25 and 30 pphr. The SEM micrographs showed that the dispersion of the fillers in the hybrid composites up to 15wt% replacement of CB was very good. Higher strengths were obtained up to 25 pphr for composites that contained 95wt%CB/5wt%NCC and 90wt%CB/10wt%NCC, while the composites that contained 85wt%CB/15wt%NCC showed higher strength up to 20 pphr compared to the CB filled samples. The NR filled with hybrid CB/NCC up to 15wt% replacement of CB offered comparative hardness and abrasion resistance; while 95wt%CB/5wt% NCC filled sample showed lower compression set over CB reinforced samples up to 30 pphr and comparative tensile strength, hardness, elastic modulus and abrasion resistance. As single filler, the synthesized nanoparticles imparted significant improvement in the mechanical properties of vulcanized NR; however, the properties were inferior to the CB reinforced sample due to poor dispersion of the NCC in vulcanized NR. The thermal and oxidative stability of the hybrid composites up to 15wt% replacement of CB were better than those of the CB filled samples.

If Augmented Reality is Really Effective as a Teaching Tool, Why is it Not Used in Distance Education?
Authors: Chadeea Tomal Kumar , Prinsloo Paul
Published: August 2022

In the past two decades, Augmented Reality (AR) has been increasingly receiving attention within the field of education, providing evidence of the positive impact of AR on the effectiveness of teaching and learning in several disciplinary contexts. Despite the evidence, there is a paucity of large-scale adoption of AR in higher education and no evidence of the deployment of AR in distance learning environments. The evolution of Distance Education (DE) has always been linked to advancements in (educational) technology in ameliorating the transactional distance between providing institutions and learners, supporting learners synchronously and asynchronously, as well as providing educators with tools to increase the effectiveness of pedagogy and use of resources. It is therefore unclear why AR has not been adopted in distance and distributed learning environments. A scoping review focused on establishing the enabling conditions for adopting AR in DE and the results were deductively evaluated. The results of the scoping review did not find any frameworks or models to guide the implementation of AR but pointed out several elements that need to be considered in the adoption of AR. This study resulted in a conceptual model identifying several pedagogical and organisational issues that may affect the adoption of AR in Distance Education.

Context: Inappropriate prescribing of antibiotics can result in serious patient harm. Aims: To investigate the incidence, nature, clinical severity, and causes of antibiotic prescribing errors (APEs) in the emergency department (ED) of a large hospital in Jordan. Methods: A mixed-method approach was used to explore the incidence and types of APEs by direct observation of electronic prescriptions (EPS) of antibiotics over four weeks, and to identify causes of errors by semi-structured interviews with ED physicians. The clinical severity of APEs was rated by a committee of experts. SPSS V26 and NVivo 10 were used for the analysis of quantitative and qualitative data, respectively. Results: The incidence of APEs caused by the use of EPS was 4.3%. Wrong quantity (32.62%), wrong dose (15.25%), and duplicate drugs (13.55%) were identified as the most common types of APEs. More than one-third of APEs identified were deemed clinically significant, seven were serious, and one was lethal. Minor and significant antibiotic APEs across physicians who attended workshops on EPS and those who did not were 75.00% versus 46.77% (p = 0.001) and 18.75% versus 52.41% (p = 0.013), respectively. Three major causes of errors were identified: 1) System-related (system crash, drop-down menu), 2) user-related (lack of computer skills), and 3) workplace-related (overcrowding, inadequate staffing). Conclusions: APEs generated by the use of EPS were common in EDs in Jordan, clinically significant, and multifactorial.

Context: Adverse drug reactions represent one of the leading causes of hospitalization and death. Aims: To characterize adverse reactions due to antibiotics and nonsteroidal anti-inflammatory drugs in outpatients over 18 years of age. Methods: Cross-sectional descriptive observational study. It included outpatients aged 18 years or older who went to public health care centers and who presented a health problem, for which they were treated with antibiotics or nonsteroidal anti-inflammatory drugs (NSAIDs). The information was collected through an adaptation of the adverse drug reaction (ADR) report format in outpatients. Results: A sample of 4,573 participants was obtained, of which 556 (12.4%) people presented adverse drug event, 550 ADR were detected by NSAIDs and antibiotics, of which, 51.4% (291) were classified according to Naranjo’s algorithm as probable, 37.8% (214) as possible and 8.0% (45) as defined. According to the Rawlins and Thompson classification the majority were type A with 413 (75.1%). The severity was mostly mild, with 471 (85.6%) and the manifestations of the digestive system predominated with 440 (80.0%). Conclusions: It is necessary to promote and strengthen pharmacovigilance activities, as well as the training and updating of health personnel in the detection of ADR, since in many cases these can be avoided, contributing to patient safety and the reduction of public spending on health, especially in low-income countries.

Context: Several experimental results and clinical reports using Mangifera indica L extract (MSBE) suggest its potential utility in osteoarthritis (OA) mixed pain. Aims: To examine the possible therapeutic effects and safety of supplementation on osteoarthritis (OA) pain. Methods: Fifty patients with painful knee OA who had undergone a year of conventional treatment that included paracetamol and non-pharmacological therapies were randomly allocated to the experimental group (n = 21), which received a daily dose of 900 mg of extract supplementation or preceding usual treatment and placebo in the same form (n = 17) for a period of 120 days. The primary measure outcome was the change in the average daily pain diary score (ADPS) using the Likert scale. Also, a multidimensional measure of pain, stiffness and functional disability on The Western Ontario and Mc Master Universities (WOMAC) index for knee OA and ultrasonographic chronic signs of synovitis such as effusion and synovial thickness were evaluated. Results: Change from baseline in ADPS of the MSBE supplemented group showed a significant reduction after two weeks that lasted for 120 days with respect to the placebo group. Significant improvements in pain and functional disability WOMAC sub-scores, number of joints with synovial thickness and effusion after MSBE supplementation vs. placebo were observed. Non-adverse effects were reported in the experimental group. Conclusions: These results suggest that MSBE supplementation has a beneficial effect on OA pain and disability.

Context: Piper cubeba L. (family Piperaceae) is used traditionally for the treatment of many diseases, including cancer. Aims: To determine the anticancer activity of P. cubeba crude extracts on cancer cells and identify chemical constituents of the active fraction. Methods: Seeds of P. cubeba were sequentially extracted with dichloromethane followed by methanol and purified using column chromatography. Fractions were screened the cytotoxicity against triple negative breast cancer (MDA-MB-468) using MTT assay. Then, active fractions were evaluated cytotoxicity against breast cancer (MCF-7 and MDA-MB-231), colon cancer (HT-29), cholangiocarcinoma (KKU-M213) and normal fibroblast (L929) cells. Total phenolic, tannin, and flavonoid contents of active fraction were investigated, and the chemical composition was analyzed using GC-MS. Flow cytometry was applied to determine the cell cycle, apoptosis, and evidence of caspase activation. Results: Fraction DE14 and DE15 showed cytotoxic activity against MDA-MB-468. Fraction DE15 exhibited the most potent cytotoxicity against MDA-MB-231, KKU-M213, HT-29 and L929. As the fraction DE15 was of dichloromethane extraction, major contents were nonpolar fatty acids and fatty acid esters, followed by propylene glycol and hydrocarbons. The phenolic compounds were however traceable, leading to their measurable antioxidant property. This extract did not cause cell cycle arrest on MDA-MB-231. However, fraction DE15 significantly increased apoptotic cells at 48 and 72 h, and significantly induced multi-caspases activity on MDA-MB-231 in a time-dependent manner. Conclusions: Fraction DE15 exhibited cytotoxicity effect and induced apoptosis on triple negative breast cancer and showed less toxicity on normal fibroblast cells.

Context: The COVID-19 outbreak is caused by the transmission and infection of SARS-CoV-2 at the end of 2019. It has led many countries to implement lockdown policies to prevent the viral spreading. Problems arise in a COVID-19 patient because of viral infection that leads to a systemic response in the immune system, specifically due to cytokine storm. Moreover, the antiviral drugs that have not been found. Indonesia had a variety of traditional medicines, such as is ‘jamu’. It consists of a mixture of natural ingredients such as Moringa oleifera Lam. and Curcuma longa L. Aims: To identify the activity of dual inhibitors as antiviral and anti-inflammatory agents from herbal combination compounds. Methods: Sample was collected from PubChem (NCBI, USA) and Protein Data Bank (PDB), then drug-likeness analysis using Lipinski rule of five in SCFBIO web server and bioactive probability analysis of bioactive compounds were conducted by PASS web server. Furthermore, the blind docking method was performed using PyRx 0.8 software to determine the binding activity and molecular interaction by PoseView web server and PyMol software v2.4.1 (Schrödinger, Inc, USA). Results: Cryptochlorogenic acid and curcumin have been computationally proven as dual inhibitors for antivirals by inhibiting Mpro SARS-CoV-2 and as anti-inflammatory through inhibition of NFKB1 activity. However, the results are merely computational so that it must be validated through a wet lab research. Conclusions: The combination of Moringa oleifera Lam. and Curcuma longa L. is predicted to have antiviral and anti-inflammatory activity through dual inhibitor mechanism played by cryptochlorogenic acid and curcumin.

Authors: Aldulaymi Raghad , Al Meslamani Ahmad Z.
Published: August 2022

Context: In the emergency department, patients with recent-onset atrial fibrillation are typically managed with intravenous antiarrhythmic agents. However, the currently used agents have a low efficacy and safety profile. Antazoline is an antihistaminic agent that has been shown to have a strong antiarrhythmic effect when administered intravenously, facilitating rapid conversion to normal sinus rhythm. Aims: To systematically review the literature on the safety and efficacy of antazoline in the treatment of recent-onset short-duration atrial fibrillation and to compare the clinical efficacy of antazoline to that of other antiarrhythmic agents listed in clinical guidelines. Methods: The study was written in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. A comprehensive search of databases (PubMed, Scopus, ScienceDirect, Web of Sciences, Google Scholar, Clinical trial.gov) for relevant studies in English from inception to 2021 using keywords involving “antazoline” AND other terms such as “antiarrhythmic”, “atrial fibrillation”, and “arrhythmia”. Results: Of the 478 studies identified, 446 were screened, and 7 were included, one of which was a randomized control trial, and the others were observational studies. The majority of studies indicated that antazoline resulted in rapid cardioversion to sinus rhythm. When compared to other pharmacological cardioversion options, antazoline achieved higher cardioversion rates than amiodarone or propafenone and was generally a safer option. Conclusions: Antazoline appears to be an effective pharmacological agent for the rapid cardioversion of short-term atrial fibrillation. More randomized clinical trials, however, should be conducted to strengthen the evidence.

Context: The ethnobotanical study of the plants used is of great interest in the medical field. In this perspective, we have carried out this ethnobotanical and ethnopharmacological study, which is part of the development of plant resources traditionally used against anemia in a large region of Middle Atlantic Morocco (Mam-4): Al Haouz-Rehamna. Aims: To establish a catalog of medicinal plants used in traditional medicine against anemia disease. Methods: For this purpose, we carried out an ethnobotanical survey using 1700 questionnaire cards during five campaigns (from 2012 to 2017) in the studied field. In addition, the information sought was about the plant including its local name, its part used, its toxicity and, medical practices related. Ethnobotanical indices, such as Use Value (UV), Family Use Value (FUV) and, Plant Part Value (PPV), were determined. Results: The results allowed us to identify 48 medicinal plants of which 12 were toxic. The inventoried species were distributed in 45 genera and belong to 27 botanical families, of which four predominated in the number of species: Apiaceae, Amaranthaceae, Fabaceae, and Asteraceae. Also, 11 species were traditionally more used as effective plants against anemia: Rubia peregrina, Lens culinaris, Malva sylvestris, Beta vulgaris, Spinacia oleracea, Mercurialis annua, Hibiscus sabdariffa, Corrigiola telephiifolia, Nasturtium officinale, Cistus laurifolius and Armeria mauritanica. The leafy stems were the most used part (PPV = 0.28%) followed by the seed (PPV = 0.26%). These parts were usually used steamed, decocted, and rarely triturated in honey or infused in water. The recipes were administered orally until cured. Conclusions: The present study established the importance of documenting traditional knowledge about the species of medicinal plants that are used to correct many chronic diseases such as anemia. Analysis of this knowledge has shown that several of the listed plants promoted anti-anemia activity and could become the basis for in-depth scientific investigations.
