The phenomenon of religious radicalism has become a global threat of the 21st century that phenomenon was a result of Islam as anaccused religion and was often associated with a terrorist religion. Educational institutions often "suspected" in creating of terrorists’ generations because the content material of Islamic Religious Education Study was dogmatic, indoctrinated, and related to proselytizing spirit that confirms truth claims. Anyway, substance of instructional materials used in senior high school does not contain inclusive religious content so it can create an exclusive and intolerant religious behavior among senior high school students. The aim of this study; 1).Providing foothold among students of theological and sociological thinking and behavior in order to have an inclusive and tolerant religiosity 2).Deploying and seeding ideas and behavior of an inclusive and tolerant religiosity as a form of resistance ideology (de-radicalization). 3). Filling the void literature Islamic Religious Education Study particular model of inclusive diversity relevant to mainstream Islam in Indonesia. To counteract the religious radicalism among students, the teaching material of Islamic Religious Education Study must contain religious inclusive content incorporating the teachings of Islam as a religion Rahmatan Lil Alamin, a religion of tolerance which is supported by the argument of the Qur'an and hadith. By using this model of teaching materials is expected of senior high school students have an inclusive religious behavior that is relevant to the character and Indonesian Islam mainstream in order to prevent radicalism behavior among senior high school students.

Authors: Et al. Jabbar 
Published: March 2019

This study was focused on biotreatment of soil which polluted by petroleum compounds (Diesel) which caused serious environmental problems. One of the most effective and promising ways to treat diesel-contaminated soil is bioremediation. It is a choice that offers the potential to destroy harmful pollutants using biological activity.
Four bacterial strains were isolated from diesel contaminated soil samples. The isolates were identified by the Vitek 2 system, as Sphingomonas paucimobilis, Pentoae species, Staphylococcus aureus, and Enterobacter cloacae. The potential of biological surfactant production was tested using the Sigma 703D stand-alone tensiometer showed that these isolates are biological surfactant producers. The better results of the surface tension reduction test were obtained using the mixed bacterial culture which reduced the surface tension of the medium from 66mN/m to 33.89mN/m. For further evidence of the biodegradation effect of these isolates individually and as a mixed culture, which was supported by the use of Gas-Chromatography technology confirming the occurrence of biodegradation.
The capability of mixed bacterial culture was examined to remediate the diesel contaminated soil in bio piles system. Two pilot scale bio piles (25 kg soil each) were constructed containing soils contaminated with approximately 2140 mg/kg total petroleum hydrocarbons (TPHs). Both systems were equipped with oxygen to provide aerobic conditions, incubated at ambient temperature and weekly sampling within 35 days (during summer season). Overall 75.71 % of the total petroleum hydrocarbons were removed from the amended soil and 33.18 % of the control soil at the end of study period. The study concluded that the ex-situ bioremediation (bio piles) is a good option for treating the soil contaminated with diesel as economical and environmentally friendly.
Enhancement of Hydrothermally Co3O4 Thin Films as H2S Gas Sensor by Loading Yttrium Element
Authors: Et al. Hamdan 
Published: March 2019

The gas sensing properties of Co3O4 and Co3O4:Y nano structures were investigated. The films were synthesized using the hydrothermal method on a seeded layer. The XRD, SEM analysis and gas sensing properties were investigated for Co3O4 and Co3O4:Y thin films. XRD analysis shows that all films are polycrystalline in nature, having a cubic structure, and the crystallite size is (11.7)nm for cobalt oxide and (9.3)nm for the Co3O4:10%Y. The SEM analysis of thin films obviously indicates that Co3O4 possesses a nanosphere-like structure and a flower-like structure for Co3O4:Y.
The sensitivity, response time and recovery time to a H2S reducing gas were tested at different operating temperatures. The resistance changes with exposure to the test gas. The results reveal that the Co3O4:10%Y possesses the highest sensitivity around 80% at a 100oC operating temperature when exposed to the reducing gas H2S with 0.8sec for both recovery and response times.

Experimental Investigation on Clay-Fluid Interactions for Enhanced Wellbore Stability
Authors: Al-Arfaj Mohammed , Amanullah Md. 
Published: March 2019

Abstract
The use of water-based drilling fluids to drill shale formations causes wellbore stability problems as a result of the reaction of water with clay minerals. When it comes in contact with water, clay starts to react, swell and/or disperse leading to shale disintegration and sloughing. Consequently, tight hole might develop and/or higher solids loading in the wellbore might be experienced and, hence, the chance to get stuck pipe increases and the hole cleaning efficiency of drilling fluid decreases significantly.
This paper describes the experimental work conducted on four shale samples to assess clay-fluid interactions and shale stabilization. After conducting mineralogical analysis using X-ray diffraction, shale inhibition tests including dispersion and swelling tests were carried out using de-ionized water, 5% potassium chloride brine and 5% Polyamines solution. The work has been extended to cover different pure clay samples: sodium montmorillonite, illite and illite smectite mixed layer.
Cation exchange capacity results showed high reactivity in sodium montmorillonite and illite-smectite mixed layer as they are more willing to exchange cations and adsorb water at natural conditions. Similarly, shale samples with higher concentration of smectite and illite-smectite showed higher CEC values. Dispersion results showed that shale recovery percentages varied from 30.8% for shale sample dominated by kaolinite to 98.65% for those with low kaolinite content. For the high kaolinite sample, the recovery percentage jumped from 30.8% to 59% with potassium chloride and eventually to 85.5% when the polyamine solution was used. When the samples were tested in the swell meter, results showed higher swelling percentage values for those samples with higher smectite content followed by illite while two samples showed no potential swelling as they have low clay content of less than 15%.

Abstract
The present study was carried out to reduce the size of silver nanoparticles (AgNPs) by optimizing physico-chemical conditions of the Aspergillus fumigatus BTCB10 growth based on central composite design (CCD) through response surface methodology (RSM). Variables such as a concentration of silver nitrate (mM), NaCl (%) and the wet weight of biomass (g) were controlled to produce spherical, monodispersed particles of 33.23 nm size, observing 78.7% reduction in size as compared to the initially obtained size that was equal to 356 nm. The obtained AgNPs exhibited negative zeta potential of –9.91 mV with a peak at 420 nm in the UV-Vis range whereas Fourier Transform Infrared (FT-IR) analysis identified O–H, C = C, C ≡ C, C–Br and C–Cl groups attached as capping agents. After conducting RSM experiments, a high nitrate reductase activity value of 179.15 nmol/h/ml was obtained; thus indicating a likely correlation between enzyme production and AgNPs synthesis. The F-value (significant at 3.91), non-significant lack of fit and determination coefficient (R2 = 0.7786) is representative of the good relation between the predicted values of response. We conclude that CCD is an effective tool in obtaining significant results of high quality and efficiency.

Published: March 2019

Purpose: to evaluate subfoveal choroidal thickness (SFCT) and other anatomical parameters of the eye in the early stages after orthokeratological correction of myopia. Material and Methods. The study was conducted on 20 myopic Caucasian patients (40 eyes) with moderate myopia. The main group consisted of 10 children with myopia -4.5 ± 1.03 D aged 11 ± 2.26 years, who were examined before the correction with orthokeratological lenses (OK-lenses) ESA-DL (Dr Lens Tehno, Russia) and 3 weeks after it. The control group comprised 10 patients (20 eyes) with myopia -3.84 ± 1.12 D aged 11.6 ± 1.17 years, who wore monofocal glasses as a correction. SFCT was measured with RS-3000 Advance optical coherent tomograph (OCT) (Nidek, Japan), while axial length (AL), peripheral eye length (PEL), and anterior chamber depth (ACD) was measured with IOL Master 500 optical biometer (Carl Zeiss, Germany), and central cornea thickness (CCT), epithelial thickness (ET) and corneal stroma (ST) thickness, with OCT Avanti Rtvue XR (Optovue, USA). All patients were tested before and 3 weeks after the start of wearing lenses or glasses. Results. SFCF increased by 24.25 ± 19 μm as compared with changes in the control group (p < 0.001) after 3 weeks of wearing OK-lenses. A notable negative correlation of changes in AL and SFCT was revealed in the main group (r = -0.48). CCT decreased by 14.6 ± 2.54 μm in the group wearing OKlenses. The main OK-lens contribution to the statistically significant change in the CCT concerned the epithelium, whose thickness showed a 12.7 ± 1.58 μm (22.6 %) change as compared with the initial data (p < 0.001) and with the change in the control group (p < 0.001). The decrease in AL showed an insignificant correlation with the decrease in the CCT: r = 0.16. ACD, PEL and ST did not change significantly (p > 0.05). Conclusion. SFCT shows an increase in the early stages after OK correction. When controlling the growth of the eye in patients with OK lenses, we need to take into account the impact of the choroid on the results of AL measurement.

Purpose. To study the relationship of biometric parameters, visual acuity, eye refraction and intraocular pressure (IOP) with blood glucose levels and glycated hemoglobin (HbA1c) in patients with subcompensated insulin-requiring type II diabetes mellitus. Material and methods. Ophthalmic monitoring lasted 3 years, the experience of insulin therapy — 6 years. 32 patients (27 women and 5 men) with insulin-requiring diabetes mellitus and no severe general diabetic complications or concomitant eye pathology were monitored for 3 years. The patients’ average age was 60.4 ± 5.3 years; average weight 94.3 ± 16.5 kg; average height 163.4 cm; average BMI (body mass index) was 29.93 kg/m2, all received insulin treatment for 6 years. Patients determined the level of blood glucose themselves on a daily basis using individual “Accu-Check” and/or “OneTouch select” glucometers, supplemented by endocrinologist checks on scheduled examinations once a month. The level of glycated hemoglobin (HbA1c) was determined once every 3–6 months. The 3-year ophthalmic monitoring involved both eyes and included biomicroscopy, autorefractometry, pneumotonometry, measurement of the anterior-posterior axis, the depth of the anterior chamber and lens thickness; pachymetry of the cornea in the central optical zone, and ophthalmoscopy. Visometry was performed according to ETDRS (Early Treatment Diabetic Retinopathy Study Research Group) requirements. Results. The impact of blood glucose level on visual acuity (Spearman R = 0.18/-0.23, t (N-2) = 1.07/-1.34, p = 0.1) is higher than that of HbA1c (Spearman R = 0.07/-0.15, t (N-2) = 0.4/-0.8, p = 0.65) The higher the glucose level, the lower the depth of the anterior chamber and the shorter the APA. In contrast, the higher the level of HbA1c, the thicker the cornea in the central optical zone. Both the glucose and the HbA1c levels reveal a similar positive correlations with IOP. A refraction shift toward myopia from 42 % to 55 % was shown to correlate to HbA1c, and a corresponding reduction of hyperopia share was revealed. Conclusions. In patients with subcompensated insulin-requiring diabetes mellitus type II, biometric parameters, refraction and intraocular pressure are determined by changes in the level of blood glycemia.

Published: March 2019

Purpose. To study and classify artifacts of spectral-domain optical coherence tomography (OCT). Material and methods. The retrospective study included OCT data of 112 patients (112 eyes) examined on two Cirrus HD-OCTs (Carl Zeiss Meditec) sequentially for three days (macular area examinations, 67 patients) and five days (examination of the optic disc region, 62 people), including 17 people who underwent both types of examination. Both the original scanning data (B-scans) and the results of their subsequent analysis were evaluated for the presence of artifacts. Results. The criteria of OCT artifacts were suggested and their practical classification was proposed, which distinguishes three types of artifacts: segmentation errors/errors in delineation of the optic disc borders, "out-of-register" artifacts and displacement/fallout of B-scans, and eight main causes of artifacts. The frequency of artifacts ranged from 19 % (analysis of the optic disc area) to 37 % (analysis of the macular area) and 65 % (evaluation of the ganglion cell-inner plexiform layer). The most common were segmentation errors in patients with pronounced pathology or epiretinal membranes (fibrosis). Conclusion. Clinically significant OCT artifacts occur in 19–65 % of cases, depending on the analyzed eye fundus structures. The most common artifacts are segmentation errors in patients with pronounced pathology and epiretinal membranes (fibrosis). A practical classification of OCT artifacts is proposed, which distinguishes three main types and the most important causes of their presence.

Published: March 2019

Background:
In the procedures of surgical pathways it is important to create opportunities for developing active forms of engagement and extending the patients’ health maintenance knowledge, which is essential in nursing. One way is to understand more about the concept of coproduction.

Objective:
The purpose was to use experiences from spinal surgery patients’ narratives to explore the conceptual model of healthcare service coproduction.

Method:
A prospective qualitative explorative approach was performed and analyzed in two phases with inductive and deductive content analysis of data retrieved from five focus group interviews of 25 patients with experiences from spinal surgery interventions.

Result:
The findings indicate that mutual trust and respect, as well as guidance given in dialogue, are two important domains. An illustration of how to apply the conceptual model of healthcare service coproduction was revealed in the descriptions of the three core concepts co-planning, co-execution and civil discourse.

Conclusion:
This study highlights what is needed to reach coproduction in healthcare services concerning patients with spinal disorders. Development of care plans that focuses on co-planning and co-execution is recommended which are structured and customizable for each patient situation to make coproduction to occur.
