Authors: Samanhudi Samanhudi , Yunus Ahmad , Rahmanto Rahmanto 
Published: June 2021

<p><em>Tribulus terrestris</em> is conventionally propagated using seeds but has limited germination capacity. One approach that can be done for this plant multiplication is in vitro tissue culture. This study was conducted to determine the growth potential of <em>T. terrestris</em> in vitro by the addition of auxin (IAA) and cytokinin (BAP) as growth regulators at several concentrations. The study was conducted at the Laboratory of Plant Physiology and Biotechnology, Faculty of Agriculture, Universitas Sebelas Maret Surakarta from February to December 2017. The experiment employed factorial Completely Randomized Design (CRD) method with 2 factors, namely IAA concentration (0 ppm, 0.1 ppm, 0.2 ppm, 0.3 ppm), and BAP concentration (0 ppm, 0.3 ppm, 0.5 ppm, 0.7 ppm). The observed growth parameters were shoot emergence time, leaf emergence time, root emergence time, number of leaves, and number of roots. Data were analyzed using analysis of variance followed by DMRT with a 95% confidence level. The results showed that the addition of IAA only affects leaf emergence time, while the addition of BAP had a significant effect on the leaf emergence time and number of leaves. The interactions between IAA and BAP had a significant effect on leaf emergence time.</p><p> </p><p align="left">Keywords: explant; plant growth; tissue culture.</p>

Abstract
Background: The patients on mechanical ventilation were always critically ill and ventilation may cause injury and inflammatory disorders in the lungs of such patients. We sought to determine whether statin treatment has a protective effect on the outcome of the ventilated patients. Methods: A retrospective observational study of mechanically ventilated patients from the Medical Information Mart for Intensive Care III (MIMIC-III) database. To ensure the robustness of the findings, we utilized the gradient boosted model, propensity score analysis, doubly robust estimation and an inverse probability‐weighting model in the statistical procedure. The propensity score of statin use was calculated by age, sex, severity scores and 32 other variables. Results: Compared with nonusers, the use of statins was associated with improved 28-day survival in the unmatched cohort (HR 0.85 95% CI 0.80~0.90) and matched cohort (HR 0.79 95% CI 0.73~0.85). Statin use was also associated with improved 60-day (HR 0.81 95%CI 0.75~0.85), 90-day (HR 0.81 95%CI 0.76~0.86) and in-hospital (HR 0.81 95%CI 0.76~0.86) survival in the matched cohort. Statins use was associated with longer ventilator free days (VFD28, 14.93±13.11 vs 12.06±13.26) and longer ICU free days (13.41±12.14 vs 10.86 ±12.19) in the matched cohort. Different types of statins were associated with improved 28-day survival. The subgroup analyses results showed improved 28-day survival in most subgroups, but this improvement was not observed in patients with pneumonia, septicemia or acute respiratory failure. Conclusions: In a population of mechanically ventilated patients, the use of statins may be associated with reduced mortality. This protective effect was observed only in mild-to-moderate patients instead of critical inflammatory ones.Trial registration: http://www.chictr.org.cn/index.aspx; Registration number: ChiCTR2000029594

Published: June 2021

Abstract
The present research proposes a new particle swarm optimization-based metaheuristic algorithm entitled “search in forest (SIF) optimizer” to solve the global optimization problems. The algorithm is designed based on the organized behavior of search teams looking for missing persons in a forest. According to SIF optimizer, a number of teams each including several experts in the search field spread out across the forest and gradually move in the same direction by finding clues from the target until they find the missing person. This search structure was designed in a mathematical structure in the form of intra-group search operators and transferring the expert member to the top team. In addition, the efficiency of the algorithm was assessed by comparing the results to the standard representations and a problem with the genetic, grey wolf, salp swarm, and ant lion optimizers. According to the results, the proposed algorithm was efficient for solving many numerical representations, compared to the other algorithms.

Abstract
Purpose: Despite follicular lymphoma (FL) is frequently characterized by a moderate increase of glucose metabolism, PET/CT examinations provides valuable information for staging and response assessment of the disease. The aim of the study was to assess and compare the diagnostic performance of PET/ldCT and PET/ceCT, respectively, in evaluating FL patients at the end of treatment. Methods: Fifty FL consecutive patients who underwent end-of-therapy PET/CT with both ldCT and ceCT were analyzed. Two blinded observers independently assessed PET/ldCT and PET/ceCT applying the Deauville score (DS) and Lugano classification criteria. PET imaging obtained after the end-of-treatment (EoT) was classified as showing PET and ce-CT matched response (concordant imaging group, CIG) or PET and ce-CT unmatched response (discordant imaging group, DIG). Relapse rate and Event-Free Survival (EFS) were compared between CIG and DIG patients. Results: Overall, no differences in metabolic response classification were observed between PET/ldCT and PET/ceCT. In 13 (26%) patients PET/ceCT identified additional FDG-negative nodal lesions in mesenteric, retroperitoneal and iliac regions. However, in all cases, final DS remained unchanged and the additional results did not modify the following therapeutic decision. Among patients, who obtained complete metabolic response a comparable rate of relapse was registered in DIG 3/13 (23%) and CIG subgroups 5/20 (25%) [p = 0.899]. In all 3 DIG cohort patients who relapsed the recurrent disease involved also, but not exclusively, PET negative lymph nodes detected by ceCT. In overall population metabolic response defined by PET/ldCT predicted EFS (76% vs 35%, p = 0.0013) significantly better than ceCT-Based response assessment (75% vs 53%, p = 0.06). Conclusion: Our study demonstrates a negligible diagnostic and predictive value of ceCT performed in addition to standard 18FDG PET/ldCT for EoT response evaluation in FLs. PET/ldCT should be performed as first-line imaging procedure, also in patients with prevalent abdominal and pelvic involvement, limiting the acquisition of ceCT in selected cases. This tailored approach would contribute to avoid useless radiation exposure and preserve renal function of patients.

Abstract
This paper has proposed a user-density-based coverage optimization technique for ultra-dense cellular networks. Antenna tilting is a promising coverage optimization technique to be used in 5G networks that significantly improve the signal to interference plus noise ratio (SINR) by choosing the appropriate angle of tilt. In this paper, the cellular coverage has been optimized for scattered user densities/user-hotspots using an adaptive antenna tilting mechanism that steers the beams towards the temporal hot spot in the coverage area. The proposed method has the competence to improve the desired SINR level and coverage area for a group of the user rather than a single user. In this work, a reinforcement learning (RL) algorithm has been implemented to optimize the tilt angle. The performance of the proposed technique has been evaluated in the simulation platform considering a three-sectored multicellular mobile network where the groups of user clusters are distributed randomly. The result confirms the improvement in RSS and SINR value in the group of users having high density with maximum user satisfaction.

Abstract
Now-a-days, with the augmenting accident statistics, Vehicular Ad-hoc Networks (VANET) are turning out to be more popular, which in-turn eradicates accidents in addition to damage to the vehicles together with populace. In a VANET, message can well be transmitted within a pre-stated region to attain safety of a system and also its efficacy. Next, it is challenge to ensure authenticity of messages in such a dynamic environment. Though some researchers have already worked on this, security has not been much focussed. Thus, secured data communication with enhanced security on the VANET environment utilizing the American Standard Code for Information Interchange centred Elliptic Curve Cryptography (ASCII-ECC) is proposed. The proposed scheme allows all vehicles to register with the Trusted Authority (TA) and uses Median-centred K-Means (MKM) to find out the cluster head among all cluster and at the last phase verification is done by TA. The performance of the proposed algorithm ASCII-ECC is analysed and proved that the system renders better performance when it is weighed against the top-notch methods.

Published: June 2021

Abstract
The frequency and intensity of extreme events especially Heat Waves (HW) are growing all around the world which ultimately poses a serious threat to the health of individuals. To quantify the effects of extreme temperature, appropriate information, and the importance of HW and Heat Index (HI) are carefully discussed for different parts of the world. Varied definitions of the HW and HI formula proposed and used by different countries are carried out systematically continent-wise. Different studies highlighted the number of definitions of HW, however mostly used Steadman’s formulae for the calculation of HI that uses surface air temperature and relative humidity as climatic fields which was developed in the late 1970s. Since then, dramatic changes in climatic conditions have been observed as evident from the ERA5 datasets which need to be addressed. Likewise, the definition of HW, which is modified by the researchers as per the geographic conditions, necessary modification in Steadman’s equation also needs to be done. This study will help the researcher community to understand the importance of HW and HI and think about its modification which further helps in better adaptation and application. Furthermore, it opens the scope to develop an equation based on the present scenario keeping in mind the basics of an index as considered by Steadman.

Abstract
Background

Metabolic syndrome (MetS) is described as a cluster of cardiometabolic risk factors that can increase the possibility of developing atherosclerotic cardiovascular diseases. According to monastic rules, Thai Buddhist monks are not allowed to cook meals and do exercise. This unique lifestyle generally encompasses low physical activities and may cause several noncommunicable diseases. Thus, in this study, we aimed to examine the prevalence, risk factors, and perception of MetS among Thai Buddhist monks.
Methods

This was a cross-sectional study conducted among Thai Buddhist monks living in Tha Luang District, Lopburi Province, Central Thailand. Study participants completed a questionnaire inquiring about personal and health data, and they also underwent physical examination, including anthropometric measurements, before undergoing biochemical blood tests. MetS was defined based on the National Cholesterol Education Program ATP III (NCEP ATP3) criteria. A qualitative study using in-depth interview was conducted to determine the knowledge and perceptions regarding MetS among Thai Buddhist monks.
Results

In total, 96 Thai Buddhist monks were included in this study. The prevalence of MetS was 28.1%. Participants who had a body mass index of \(\ge\)25 kg/m2 were determined to have a higher risk of developing MetS (OR, 4.5; 95% CI, 1.6–13.3). The in-depth interview revealed that participants’ perceptions were directly associated with their beliefs, experience, and basic healthcare knowledge. A qualitative study identified two primary factors of MetS among Thai Buddhist monks, viz., unhealthy diet and low physical activity.
Conclusions

MetS prevalence in Thai Buddhist monks was moderate compared with that reported by other studies. Medical providers and Buddhist devotees should cooperate in providing health promotion by donating healthy food, conducting annual health checkups, and arranging alternative exercises in a private area that correspond with the monastic rules. Therefore, early screening, treatment, and patient education are the most important factors to manage MetS in Thai Buddhist monks.

Published: June 2021

Abstract
Noise pollution assessment was carried out in selected traffic junctions of Imphal city of Manipur, India. The noise pollution assessment was carried out using noise parameters and indices such as L10, L50, L90, Leq for selected traffic junctions during the different periods of the day, i.e., morning, noon, and evening hours. The study of equivalent noise level (Leq), noise parameters, and various noise indices have enabled the evaluation of the overall traffic noise environment of the city. The traffic noise indices such as traffic noise index (TNI), noise climate (NC), traffic noise pollution level (LNP), noise exposure index (NEI) along with day time (LD), night time (LN) average, and day-night (Ldn) noise levels were assessed for the selected traffic junctions. Moreover, spatial noise mapping was carried out using the geostatistical interpolation technique to evaluate the changes of traffic noise scenarios during the different time zones of the day. The Leq values in few traffic junctions exceeded the required noise standards. The study shows equivalent noise level ranging between 52.2–69.9 dB(A) during the morning (7–10 am), 52.4–69.3 dB(A) during noon (12 noon-2 pm), and 54.6–71.1 dB(A) during the evening (4–7 pm) hours, respectively.

Abstract
Dust events impose negative socio-economic, health, and environmental impacts in vulnerable areas and reflect physiochemical and biological characteristics of their sources. The purpose of this study was to assess the impacts and contribution of two dust sources on concentration and diversity of airborne fungi in one of the most frequent dusty area in the world. Air masses arriving at study area were assessed using ground wind rose and HYSPLIT model. To explore the relationship between fungi in dust sources and downwind area, the sampling was carried out from airborne dust in Arvand Free Zone as targets areas and soil of dried part of Hor-alazim and Shadegan wetlands as sources areas. The samples were analyzed in the lab to extract DNA, PCR and sequencing. The Raw DNA data were processed using Qiime virtual box to pick OTUs and taxonomy assignments. The most common fungi at the Genus level were in the order of Penicillium > Aspergillus > Alternaria > Fusarium > Paradendryphiella > Talaromyces. The similarity between air and soil fungal genera was investigated using richness and diversity indices estimation, phyloghenetic tree, PCA analysis. results show the ambient fungi community structures in Hor alazim, and Shadegan dust sources were more similar to those on dusty days than non-dusty days. To quantify the contributions of known dust sources to airborne fungi, Source tracker model was used. Results show that the main known airborne fungi sources were the Hor-alazim in dusty and non-dusty days. This study's results can help managers to identify and prioritize dust sources in terms of fungal species.
Compressive Strength of Geopolymer Concrete Composites: Modeling and Comprehensive Systematic Review

Published: June 2021

Abstract
The growing concern about global climate change and its adverse impacts on societies is putting severe pressure on the construction industry as one of the largest producers of greenhouse gases. Given the environmental issues associated with cement production, geopolymer concrete has emerged as a sustainable construction material. Geopolymer concrete is cementless concrete that uses industrial or agro by-product ashes as the main binder instead of ordinary Portland cement; this leads to being an eco-efficient and environmentally friendly construction material. Compressive strength is one of the most important mechanical property for all types of concrete composites including geopolymer concrete, and it is affected by several parameters like an alkaline solution to binder ratio (l/b), fly ash (FA) content, SiO2/Al2O3 (Si/Al) of the FA, fine aggregate (F) and coarse aggregate (C) content, sodium hydroxide (SH) and sodium silicate (SS) content, ratio of sodium silicate to sodium hydroxide (SS/SH), molarity (M), curing temperature (T), curing duration (CD) inside the oven and specimen ages (A). In this regard, a comprehensive systematic review was carried out to show the effect of these different parameters on the compressive strength of the fly ash-based geopolymer concrete (FA-GPC). In addition, multi-scale models such as Artificial Neural Network (ANN), M5P-tree (M5P), Linear Regression (LR), and Multi-logistic Regression (MLR) models were developed to predict the compressive strength of FA-GPC composites. For the first time, in the modeling process, twelve effective parameters including l/b, FA, Si/Al, F, C, SH, SS, SS/SH, M, T, CD, and A were considered the modeling input parameters. Then, the efficiency of the developed models was assessed by various statistical assessment tools like Root Mean Squared Error (RMSE), Mean Absolute Error (MAE), Scatter Index (SI), OBJ value, and the Coefficient of determination (R2). Results show that the curing temperature, sodium silicate content, and ratio of the alkaline solution to the binder content are the most significant independent parameters that influence on the compressive strength of the FA-GPC, and the ANN model has better performance for predicting the compressive strength of FA-GPC in compared to the other developed models.

Published: June 2021

Abstract
Purpose: We investigated the interactive role of Si-mediated attenuation to aluminum (Al) toxicity in two sugarcane cultivars (‘CTC9002’ and ‘CTC9003’) grown in hydroponic conditions. Methods: Two pot experiments were distributed in randomized blocks in a factorial design (4 × 2) with four replications. The treatments consisted of 0, 10, 15, and 20 mg L−1 Al (as aluminum sulfate [Al2 (SO4)3·18H2O)], which were combined with the absence and presence of Si [(2.0 mmol L−1 as potassium silicate (K2SiO3)]. Results: Both sugarcane cultivars (‘CTC9002’ and ‘CTC9003’) were affected by Al toxicity (above 10 mg L−1), resulting in nutritional disorders and decreasing plant growth, which were drastically reversed by Si addition in the growth medium. Si supplementation decrease Al concentration and translocation to the shoots of both cultivars when Al and Si were simultaneously supplied in the growth medium. We demonstrated that in shoots of both sugarcane seedlings, Si concentration are positively related to the lignin concentrations (ranging from 12.0% to 41% in cv. ‘CTC9002’ and 12% to 47% in cv. ‘CTC9003’). In addition, Si fertilization enhanced mineral nutrition and use efficiency of macros- and micronutrients, irrespective of the cultivar. Therefore, the use of cultivar ‘CTC9003’ under Si fertilization is more recommended to cope with the adverse effect caused by Al stress. Conclusions: The findings of this study suggest that Si fertilization in sugarcane seedlings is an economic and viable strategy strongly recommended to cope with the adverse effect caused by Al toxicity at concentrations less than 20 mg L−1, which lead to increase the shoot biomass production.
