Abstract
This study aims to explore the best level of Indigofera zollingeriana as concentrate substitution in elephant grass-based rations on the availability of macro minerals (Ca, P, Mg, and S) in kacang goats. This study investigated 12 kacang goats weighing 11 to 12 kg were investigated. The data were collected using an experimental method with a completely randomized design (CRD), consisting of three treatments and four replications. They were P1: 60% elephant grass + 30% concentrates + 10% Indigofera zollingeriana; P2: 60% elephant grass + 20% concentrates + 20% Indigofera zollingeriana; and P3: 60% elephant grass + 10% concentrates + 30% Indigofera zollingeriana. The observed variables were the availability of calcium (Ca), phosphorus (P), magnesium (Mg), and sulfur (S). The statistical analysis used was the analysis of variance. Meanwhile, the mean differences were tested using the DMRT test (Duncan’s multiple range test). The results showed that substitution for concentrates with Indigofera zollingeriana significantly affects (P0.05) the availability of Mg and S minerals. This study concludes that the concentrate substitution with 30% Indigofera zollingeriana could increase the availability of calcium (Ca) and phosphorus (P) minerals, but not affect the availability of magnesium (Mg) and sulfur (S) minerals.

Abstract
Genetic variation is an important source for plant breeding activities. Efforts to develop genetic variation are among others carried out by mutation techniques including mutation induction with gamma-ray radiation. The purpose of this study was to analyze the genetic diversity of chili pepper as a result of mutation induced by gamma-ray radiation based on morphological characters, capsaicin content, and RAPD profile. Chili pepper seeds genotype G1 were irradiated with two doses of gamma-ray 200 and 400 Gy. Analysis of morphological characters refers to the descriptor Capsicum spp. The capsaicin content of the fruit was measured using a spectrophotometric method. Genetic diversity was analyzed through profiling and scoring of RAPD DNA bands represented in the form of a UPGMA dendrogram using the NTSYS 2.10e program. Statistical analysis of quantitative morphological characters and capsaicin content were conducted using SPSS 24.0 program. Gamma-ray radiation can induce variations in morphological characters. The radiation dose of 400 Gy was more effective in producing mutant variants with the highest characters of plant height, canopy width, stem diameter, fruit length, and number of fruits. Gamma-ray radiation did not significantly increase the capsaicin content of the fruit (P 0.05). Mutant G1 chili pepper showed morphological and molecular variations. The mutant group separated from the control showed that the mutants experienced a significant change in several characters.

Abstract
Diabetes mellitus is a metabolic disease characterized by hyperglycemia as a result of insulin deficiency in the body, ineffective insulin function, or both. Glimepiride is a third generation of oral hypoglycemic drug (OHO) that has a lower risk of hypoglycemia and weight gain compared to the first generation of sulfonylurea. Petai plant (Parkia speciosa Hassk) is one of the medicinal plants that has been known to be efficacious as antioxidant and anti-diabetic. This study aimed to discover the effect of administering the seeds of petai (Parkia speciosa Hassk) on blood glucose levels in mice induced by alloxan. This experimental study used 42 mice divided into 5 groups, they were K- (a standard diet), K+ (alloxan 175 mg/kgBB), control treatments P1 and P2 with doses of 300 mg/kgBB and 400 mg/kgBB of petai seed extract, and control treatment P3 with Glimepiride 0.0026/20g. This research was conducted at Pharmacology Laboratory of the Faculty of Pharmacy and Biochemistry of the Faculty of Medicine, Andalas University. Blood sugar levels were measured by the colorimetric method using vitalab micro spectrophotometer (Microlab 300). The results of the Kruskal-Wallis test on the blood sugar levels of mice with the administration of petai seed extract at a dose of 300mg/KgBB with a mean decrease in blood sugar levels of 85.48±5.32 mg/dl and on the blood sugar levels of mice with the administration of Glimepiride 0.0026mg/20gBB with a mean decrease in blood sugar levels of 88.73±9.95 mg/dl for 7 days did not show a statistically significant difference in the Post Hoc Test with Mann-Whitney (p = 0.423) with a mean difference of reduction of 3.25mg/dl. The conclusion of this study is that the petai seed extract has the same effective effect as Glimepiride to reduce blood sugar levels in alloxan-induced mice.
Molecular Dynamics Study of CO2/H2 and CH4/H2 Gas Separation by Nanoporous Graphene
Authors: Rivero R , Ren Y 
Published: October 2022

Abstract
The combustion of coal produces CO2 emissions, rising greenhouse gas levels, and leading to global warming. Hydrogen is one potential clean source of energy. However, current hydrogen production methods produce CO and CO2 emissions, while pure hydrogen is required for fuel cells. Therefore, efficient methods for capturing greenhouse gases and the extraction of pure hydrogen are required. Membrane gas separation requires low energy and cost. However, current polymer-based membranes struggle with the trade-off between selectivity and permeability. Graphene-based membranes like nanoporous graphene (NPG) are potential candidates due to its monoatomic thickness and high mechanical performance, offering high permeability. Selectivity was altered by controlling the nanopore shape, size, and functionality, and using multi-layered NPG with various interlayer spacing and angle. Molecular dynamics simulations were performed to study the transport phenomena for graphene-based membrane gas separation. CO2/H2 and CH4/H2 gas mixtures separation were performed on a bottom-up synthesized H-Passivated NPG with Dumbbell-Shaped Nanopores. Results show that 100% H2 selectivity was achieved for both CH4/H2 and CO2/H2 gas mixtures, using single layer NPG and tri-layer NPG, respectively, while maintaining high permeability in the order of 105-106 GPU. Therefore, the H-Passivated NPG with Dumbbell-Shaped Nanopores is an excellent choice of membrane for gas separation.

Authors: Alias S , Abdul-Hakim N A 
Published: October 2022

Abstract
Recovery of plastic waste has a positive influence on solid waste management as it can bring new life to plastic waste. Hydrolysis treatment is one of the approaches for plastic waste recovery, in which plastic monomer can be recovered through depolymerisation. This study explored the recovery of polyethylene terephthalate (PET) plastic in nitric acid and leachate. The weight changes were analysed in PET when exposed to different hydrolysis agents (nitric acid and leachate) at different reaction times and temperatures. The monomer recovery of PET, known as terephthalic acid (TPA), was also evaluated. It was found that high temperatures and reaction times promoted to the high recovery of TPA. The PET residue measured as weight difference was found in line with the trend of TPA yield. The hydrolysis using nitric acid can recover more TPA than the leachate system. The knowledge obtained from this study would be beneficial in upcycling plastic waste into high-value end products.

Published: October 2022

Abstract
Due to the inexpensive cost of amine solvent, more than 95 % of natural gas (NG) processing plants use an acid gas removal unit that utilizes an aqueous amine solvent to remove sour gas components such as carbon dioxide (CO2) and hydrogen sulfide (H2S). Different technologies are available to capture CO2 from NG. However, chemical absorption is the most reliable and used technology all over the world. However, it is challenging to determine the amine blend’s optimal composition for the effective removal of CO2 and H2S and solvent regeneration. This is mainly due to the difference in reservoir gas compositions, affecting gas removal efficiency and solvent regeneration energies. The present investigation addresses the performance of using a novel solvent blend of diisopropanolamine (DIPA) and Triethanolamine (TEA) to determine the absorption capacity of CO2 & H2S using Aspen HYSYS software. A study on the effects of solubility on CO2 absorption was performed at varying pressure (10-80 bar) and temperature (25°C to 50°C). The percentage of CO2 removal increased from 80% to 98% as the temperature increased from 25°C to 50°C. The results revealed that the concentration of CO2 and H2S in sweet gas decrease with the increase in pressure while the concentration of CO2 and H2S increases with the increase in temperature.
Quality prediction for polypropylene extrusion based on neural networks
Authors: Tan C H , Yusof K M , Alwi S R W 
Published: October 2022

Abstract
In the polypropylene (PP) industry, melt index (MI) is considered the most important quality variable. Different grades of PP have their specific range of MI. Accurate prediction of MI is essential for efficient monitoring and off-grade reduction. Neural Networks (NN) modelling is proposed as the technique for MI estimation. It has powerful adaptive capabilities in response to nonlinear behaviours. By training the NN, it can discover the relationship between inputs and outputs and makes it capable of function approximation. The goal of this research is to develop NN model to predict the MI based on PP extrusion parameters. Different types of NN such as artificial neural networks (ANN), stacked neural networks (SNN) and deep neural networks were trained and compared to understand their efficiency in solving the problem. The simulation results show that deep neural networks can perform the highest accuracy prediction with the lowest root mean square error (RMSE), followed by SNN and ANN. All three modelling proved that NN can perform non-linear function approximation for polymer extrusion.

Published: October 2022

Abstract
The demand for ZnO significantly increased over the past decades. Extraction and refinement of zinc ores results in the release of hazardous wastes to the environment. In particular, the tremendous demand for disposable nitrile gloves during the Covid-19 pandemic has spiked superior demand for ZnO used as a crosslinking agent in the manufacturing process and leads to the generation of zinc containing wastewater traditionally removed via chemical precipitation. This paper focuses on the application of adsorption for zinc removal which opens an opportunity to recycle zinc to synthesize secondary zinc oxide. This study evaluated the feasibility of zinc oxide synthesis via the adsorption-desorption-chemical precipitation pathway. Palm shell activated carbon (PSAC), a low-cost adsorbent, was used for the removal of zinc from the synthetic and industrial wastewaters. Subsequently, zinc desorption was carried out using 0.3 M HCl. Then ZnO was synthesized from the desorption solutions via chemical precipitation using potassium hydroxide. Average zinc conversion rate of 98 % was achieved in this study. The synthesized ZnO exhibited high surface area of 97.4 m2/g after calcination (400 °C, 3 hr), high purity and crystallinity. The results confirmed the feasibility of zinc ions recovery for recycling to produce secondary good quality zinc oxide.

Published: October 2022

Abstract
Current desalination technologies such as thermal desalination and reverse osmosis are a process of converting seawater to freshwater. This method brings a negative impact on the environment such as CO2 emission. Solar desalination is one of the ways to resolve the current desalination challenges and more sustainable in terms of economic and environmental. Solar desalination uses solar energy as its energy consumption for evaporation. Solar desalination depends on the rate of evaporation specifically on the surface area. Hence, this study adopts the concept of cellular fluidics and 3D printing to perform capillaries rise and improve the liquid to the gas-surface area. The increase in strut diameter of the cell from 0.2 mm to 0.4 mm results in an increase of capillaries rise from 3.01 to 7.67 for Body Centered Cubic (BCC) cell geometrical shape. Different cell geometrical shape is also investigated with the strut diameter remaining constant. The Isotruss cell geometrical shape recorded a value of capillaries rise of 11.76 among the other geometrical shape due to Isotruss having more complexity in design and having internal structure.

Published: October 2022

Abstract
In present work, graphitic carbon nitride (g-CN) homojunction were synthesized to investigate the synergistic effect of photocatalysis and adsorption on Rhodamine B (RhB) dye degradation. The photodegradation (DE%) and adsorption (R%) were evaluated under the irradiation of two 50 W LED lights and in dark for 6 hours, respectively. A three-level Box-Behnken design (BBD) were employed to study the effects of initial dye concentrations (5 to 20 ppm), recirculation flow rates (1 to 3 mL/min), and the number of photoreactors (2 to 6) with total 15 sets of experiment. A quadratic regression was developed to predict DE% with an error of less than 5.5% relative to the experimental data. Additionally, ANOVA analysis showed that the number of photoreactors is the most influential parameter (p<0.05); while the two-way interaction between variables are insignificant. For the adsorption studies, Langmuir isotherm showed the best-fit result (R2>0.98) and the separation factor (RL) has indicated the adsorption process is favourable (RL=0.05). Additionally, the adsorption experimental data fit well with the pseudo-second-order kinetic model (R2>0.98). Overall, the development of homojunction photocatalyst has provided an innovative and alternative approach for water remediation.
Hydrothermal conversion of model polluted soil into zeolite P to in-situ immobilize heavy metals via zeolitization and its microstructure behavior

Published: October 2022

Abstract
To develop a new technology to remediate pollution sites stably and effectively, hydrothermal conversion of polluted soil (model soil) into zeolite P for in situ immobilization of Heavy Metals (HM) was carried out. Zeolite P could be synthesized from soil hydrothermally with a large range of Al/Si ratio (0.33–1.0) in 48 h at 200 °C. With immobilizing heavy metals (Cr, Zn and Cd), the crystallization of Zeolite P (Cr-ZP, Zn-ZP and Cd-ZP) was delayed with the order of Cr >Zn >Cd because the stronger the ligand effect of heavy metals have, the more heavily the nucleation and growth were influenced. During immobilization via zeolitization, a self-adaptive structuring behavior was confirmed by EDAX, BET and Rietveld refinement analyses: zeolite P structured more [AlO4]− to immobilize HM because the flexible 8-member-Ring channels (8 mRs) with higher Al/Si ratio could complex with more HM readily. The encapsulated HM occupied the original Na positions (Na1 and Na2) of zeolite P competitively because of their different cation size, e.g., the smallest Cr3+ could substitute all Na1 because Na1 is closer to the Framework Oxygen (FO); the largest Cd2+, however, substituted Na1 (9%) and Na2 (14%) evenly. The shrunken 8 mRs due to heavy metal immobilization also caused different chemical environments for different heavy metals immobilized because the smaller heavy metal cation could get closer to the framework, and also coordinated with more FO.

Authors: Labidi Nouar Sofiane , Mechati Boukoffa 
Published: October 2022

Abstract
Adsorption of basic blue-9 (BB9) by natural quartz mineral was tested. The quartz mineral was characterized by FTIR, SEM, DRX, zeta potential and Sear’s surface area measurements. The quartz mineral contains 99.13% of SiO2 and has a specific surface area of 0.6 m2g−1. The zeta potential measurements of quartz showed a zero point charge (ZPC) at a pH of 2.12. Adsorption experiments results of basic blue-9 showed an excellent achievement after 15 min, for 100 μm sorbent particles seize, 1.0 g l−1 sorbent mass, pH of 5.0, agitation speed of 200 rpm and Temperature of 60 °C. Moreover, the BB9 concentration and temperature were directly related to increase in adsorption capacity and the highest adsorption capacity of 27.78 mg g−1 was achieved for 30 mg l−1 at 60 °C. Langmuir isotherm and pseudo-second-order kinetics (R2 > 0.99) were found to be the most appropriate models to describe the removal of metylen blue dye by quartz mineral. The apparent diffusion parametres were estimated to be between 3.24 × 10–6 and 3.67 × 10–6 cm2 s−1, indicating an adsorption process controlled by the external mass transfert on the quartz surface. The calculated thermodynamic parameters and Dubinin–Radushkevich adsorption free energy (Eads = 0.28 kJmol−1) showed that adsorption of BB9 onto quartz was spontaneous, endothermic and a physisorption reaction. FTIR spectroscopy and semi empirical RM1 calculations established an adsorption mecanism by electrostatic attraction. The regeneration tests after four runs showed that natural quartz could be an alternative material for cationic dyes removal.

AbstractBackgroundNecrosis of frontotemporal skin and/or the ipsilateral scalp with subsequent alopecia after hyaluronic acid (HA) filler injection into the temple is rare complications with superficial temporal artery embolization are suspected as the major pathological mechanism. The main treatment currently is intralesional hyaluronidase (HAase) injection, but the effectiveness of percutaneous superficial temporal arterial HAase injection still lacks consensus.ObjectivesTo investigate the effectiveness of superficial temporal arterial HAase injection in dissolving HA filler–induced necrosis of frontotemporal skin and/or the ipsilateral scalp with subsequent alopecia.MethodsFive recent clinical cases with necrosis of frontotemporal skin and/or the ipsilateral scalp with subsequent alopecia after HA filler injection into the temple were analyzed retrospectively. The patients underwent HAase injection via superficial temporal artery combined with adjunctive treatments, and the clinical progress was observed.ResultsSignificant improvement was observed in terms of necrosis of frontotemporal skin and the ipsilateral scalp after treatment, and the patients were relieved of their clinical symptoms. Alopecia occurred approximately 1 to 2 weeks after HA filler injection, and the well-defined alopecia areas were formed 15 to 20 days after HAase injection. Patients were followed for 3 to 6 months. During follow-up, the skin lesions of all patients were restored to near normal appearance. Hair regrowth was observed 2 to 3 months after HAase treatment, and hair density nearly reached the normal level 3 to 4 months later.ConclusionsPercutaneous superficial temporal arterial HAase injection is an effective treatment option for HA filler–induced necrosis of frontotemporal skin and/or the ipsilateral scalp with subsequent alopecia.Level of Evidence: 4

Abstract

Background
The optimal management of myocardial infarction with nonobstructive coronary arteries (MINOCA) is still uncertain. This study sought to determine the association between pharmacological therapies after hospital discharge and the long-term prognosis of MINOCA patients.

Material and methods
We analyzed patients consecutively admitted to the coronary care unit with myocardial infarction (MI). Multivariate analysis was performed to determine which drugs were implicated in the prognosis of MINOCA patients. The primary endpoint was all-cause mortality at 5 years.

Results and conclusions
From a total of 3721 MI patients, MINOCA was identified in 11.6% (n = 430), of whom 56 (13.0%) experienced the primary endpoint. Median age was 66 years (IQR 19), and 51.6% (n = 222) of patients were male.
At discharge, 81.2% of MINOCA patients were prescribed aspirin, 87.4% a statin, 78.6% beta-blockers, and 66.7% angiotensin-converting enzyme inhibitors (ACEI). MINOCA patients were less likely to be prescribed these medications compared to patients with obstructive coronary artery disease (all P &lt; 0.001). 1.4% (n = 6) of MINOCA patients died in the hospital, and the 5-year mortality rate was 13.0% (n = 56). In multivariate Cox regression, treatment with ACEI at discharge was found to be independently associated with a 5-year mortality benefit (HR = 0.29, 95% CI 0.12–0.67, adjusted P = 0.004) in MINOCA patients.
In conclusion, compared with patients with obstructive CAD, patients with MINOCA are less likely to be treated with secondary prevention drugs and are at lower risk of all-cause mortality during long-term follow-up. Treatment with ACEI seems to provide an additional mortality benefit in MINOCA patients.
