Introduction
Interleukin 6 (IL-6) activates cells through its unique heterodimeric signaling complex of IL-6 receptor (IL6R) subunit and interleukin 6 signal transducer β-subunit glycoprotein 130 (gp130). The objective of this study was to investigate associations among serum levels of IL-6, sIL-6R, sgp130 and relative fluorescence intensity (RFI) of the α-subunit of the IL-6 receptor (CD126) on T-cells of HIV-1 infected and uninfected men.

Methods
Blood samples were obtained from 69 HIV-1-infected men on Highly Active Antiretroviral Therapy (HAART) with mean age of 49.1 and 52 HIV-1-uninfected with mean age of 54.3 years -. All men were participating in the Los Angeles Multi-Center AIDS Cohort Study (MACS). Serum levels of IL-6, sIL-6R, sgp130 were measured by enzyme-linked immunoassays and T-cell phenotypic analysis and RFI of CD126 on CD4+ and CD8+ by flow cytometry.

Results
Mean serum levels of IL-6, sIL6R, sgp130 and of CD126 RFI on CD4+ were 4.34 pg/mL, 39.3 ng/mL, 349 ng/mL and 526 RFI respectively for HIV-1-infected men and 2.74 pg/mL, 41.9 ng/mL, 318 ng/mL and 561 RFI respectively for HIV-1-uninfected men. The mean serum concentrations of IL-6, sIL-6R in HIV-1-infected and uninfected men were not significantly different (p>0.05). There was a positive correlation between plasma HIV-1 RNA and the levels of IL-6 (p<0.001), sIL6R (p = 0.002) but no correlation with sgp130 (p = 0.339). In addition, there was a negative correlation between serum levels of IL-6 with RFI of CD126 on CD4+ (p = 0.037) and a positive correlation between serum levels of sgp130 (p = 0.021) and sIL-6R in HIV-1-infected men.

Conclusion
Knowledge of biological variation, differences in the blood levels of biomarkers among healthy individuals and individuals experiencing illness, are very important for selection of appropriate tests for stage and progression of disease. Our data suggest no correlation among IL-6, and sIL-R6, in the treated phase of HIV-1 infection. The action and blood level of IL-6 and its receptors may be different at each stage of a disease progression.

Published: October 2023

Introduction
Maxillary surgery alone can be proposed for the surgical management of class III malocclusion, but anticipating outcomes for the labiomental muscle complex is challenging due to the mandibular autorotation phenomenon. The objective of this study was to quantify the mandibular and labiomental movements induced by maxillary osteotomy alone in the management of class III malocclusion according to different clinical and surgical variables.

Methods
The post-operative changes in mandibular and labiomental shapes were studied by geometric morphometry from the pre- and post-operative lateral cephalometric radiograph of 25 patients. The explanatory variables tested were maxillary advancement, maxillary rotation, and divergence.

Results
Soft tissues repositioning are different from postoperative mandibular repositioning after maxillary osteotomy. Neuromuscular adjustments of mandible depend on divergence and the maxillary rotation. Labiomental response only depends on divergence.

Conclusion
The surgical procedure does not have the same bone-related and musculocutaneous effects on patients with the same class III malocclusion. It is therefore essential for surgeons to understand the effects of their procedure on musculocutaneous tissues in order to best anticipate post-operative outcomes.

Objective. To determine the main demographic factors that influence preoperative expectations of patients with degenerative diseases of the lumbosacral spine.Material and Methods. A cross-sectional study was performed for 103 patients with degenerative diseases of the lumbosacral spine who were scheduled for surgery in the period from 2019 to 2021. General demographic data, level of patient’s education and the presence of previous surgeries were taken into account. Expectations for surgical treatment outcome were assessed using a translated and adapted Russian version of the Hospital for Special Surgery – Lumbar Spine Surgery Expectations Survey (HSS-LSSES) questionnaire. The quality of life of patients was assessed using the general questionnaires: European Quality of Life-5 Dimensions (EQ-5D-5L) and the 36-item Short-Form Health Survey (SF-36), as well as the disease-specific Oswestry Disability Index (ODI).Results. It was found that, according to HSS-LSSES, patients’ expectations for the upcoming surgical intervention are the higher, the older the patient’s age, the higher the general and emotional state of health, vitality, ODI scores, as well as the severity of pain syndrome, and the lower the mental health score. Patients with a high level of education and prior spinal surgery have lower expectations for subsequent surgery.Conclusion. The expectations of patients for the surgical treatment for degenerative disease of the lumbosacral spine depend on the patient’s age, level of education, anamnesis and severity of decline in the quality of life.

Published: October 2023

Attention to the negative impact of economic growth on the environment has emerged in the green economy paradigm. The utilization of hydropower can achieve green energy as part of green econony. To analyze the role of hydropower in driving Indonesia's green energy, the Autoregressive Distributed Lag (ARDL) method was employed. The results show that increased electricity production from hydropower will reduce environmental damage. Meanwhile, the use of fossil fuels will harm the environment for short and long periods. Indonesia is still in a scale of effect because environmental damage indicated by CO2 emission continuously increases due to economic activities. In addition, there is a bidirectional relationship between GDP and CO2 emissions. This means that Indonesia needs a sustainable economic growth. In addition, there is a bidirectional relationship between electricity production from hydropower and CO2 emissions. At the same time, a unidirectional causality presents from GDP to electricity production from hydropower, coal consumption to GDP, and consumption of oil and natural gas to CO2 emissions. The Indonesian government needs to establish policies which reduces consumption of fossil fuels, increases the investors’s interest in renewable energy, and expands the economic capacity to reach the expected turning point of the economic growth.
The Effect of Cone Area Variations on the Continuous Discharges Flow (CDF) Method Sedimentation Unit as a New Method for Raw Water Turbidity Removal
Authors: Ridwan Ridwan , Afrianita Reri , Putri Aulia Massyaf , Anggika Reski 
Published: October 2023

The Sedimentation Unit Continuous Discharges Flow (CDF) method is a modification by adding a continuous and controlled discharge flow as a net force acting on the particles to increase the efficiency of turbidity removal by applying the principle of a leaky tank at the bottom of the settling zone. The production capacity of the sedimentation unit using the CDF method is reduced due to the CDF flow of 6% of the flow rate so it needs to be recirculated. This study aims to maintain the production flow rate of the system and increase the efficiency of turbidity removal by recirculating the CDF flow. The research reactor consisted of a coagulation unit, flocculation unit, and sedimentation method using 6% CDF with a flow rate of 240 L/hour and 360 L/hour, and variations in the recirculation flow of 6% CDF to the flocculation unit were 0%, 25%, 50%, 75%, and 100 %. The sedimentation detention time at a flow rate of 240 L/hour and 360 L/hour was 90 minutes and 60 minutes, respectively. Research on a laboratory scale with raw water turbidity of 25,536 NTU. The results showed that the greater the CDF flow recirculation value, the higher the turbidity removal efficiency. Rank Spearman analysis, the correlation value of the CDF flow recirculation value to the efficiency of removal of turbidity is 0.980 and the significance value is 0.00 which means strong and significant. The highest turbidity removal efficiency was achieved at the 100% CDF flow recirculation value, ie at 240 L/hour flow rate was 87.21% with final turbidity 3.267 NTU, while at 360 L/hour flow rate was 82.50% with final turbidity 4,528 NTU. Uprating the flow rate in the experiment was able to produce a final turbidity value that met the drinking water quality standard, which was 5 NTU

Authors: Mesak Yulia , Meitiniarti Vincentia Irene 
Published: October 2023

Sumifix blue (SB) merupakan salah satu pewarna golongan azo yang terdapat dalam limbah tekstil. Pembuangan limbah yang mengandung pewarna tanpa pengolahan terlebih dahulu dapat memunculkan masalah bagi lingkungan dan membahayakan makhluk hidup di sekitarnya. Pengolahan dengan proses lumpur aktif dalam kondisi aerob umum digunakan dalam mengatasi limbah pewarna. Proses lumpur aktif dapat ditingkatkan dengan penggunaan mikroba pengurai pewarna. Dalam penelitian ini ingin diketahui efisiensi lumpur aktif dalam pengolahan limbah pewarna dengan penambahan E. faecalis yang telah terbukti mampu mendekolorisasi pewarna jenis azo. Selain mengkombinasikan lumpur aktif dengan E. faecalis, proses juga diuji dalam kondisi yang berbeda yaitu aerob, anaerob dan campuran (anaerob-aerob). Penelitian ini didesain menggunakan limbah cair sintetik yang mengandung pewarna SB dengan konsentrasi warna yang disesuaikan dengan limbah aslinya (absorbansi warna diukur pada l 536 nm). Pengolahan dilakukan dengan proses lumpur aktif dan kombinasi lumpur aktif dengan E faecalis pada kondisi aerob, anaerob dan campuran (anaerob-aerob) dengan sistem batch. Pengambilan sampel dilakukan setiap selang waktu 24 jam selama 96 jam. Parameter yang diamati adalah konsentrasi warna, COD dan TS. Efisiensi hasil pengurangan parameter tersebut dibandingkan pada semua perlakuan. Dari hasil penelitian ini dapat disimpulkan bahwa efisiensi pengurangan konsentrasi SB terbaik diperoleh pada proses pengolahan menggunakan lumpur aktif pada kondisi anaerob dengan presentase sebesar 86%, efisiensi pengurangan COD dan TS terbaik diperoleh dari proses pengolahan menggunakan lumpur aktif pada kondisi campuran (anaerob-aerob) dengan presentase berturut-turut sebesar 80% dan 28%. Pada penelitian ini, penambahan E. faecalis tidak terbukti meningkatkan efisiensi pengolahan SB.
Microstructural evolution and improved corrosion resistance of NiCrSiFeB coatings prepared by laser cladding
Authors: Chu Chen Ming , Natarajan Jeyaprakash , Yang Che-Hua , Ekambaram Mohan 
Published: October 2023

Abstract
Inconel 625 (IN 625) is widespread in the manufacturing of critical components such as nuclear reactors, control rods, steam turbines, supercritical boilers, rotary shafts, aerospace engines, etc., that operate in severe harsh environments. However, if the service environments consist of sulphur (fuel tanks), chlorine (supercritical boilers and heavy water plants), H2S, HCl, etc., this alloy will suffer from localized corrosion attacks that minimize its resistance towards corrosion, followed by sudden failure. This study is aimed to facilitate the anti-corrosion characteristics of IN 625 by cladding it with Colmonoy 5 (NiCrSiFeB) alloy particles. The clad microstructure was revealed by micrographs captured by means of optical and field emission scanning electron microscopy followed by the nanoindentation study to analyze the hardness offered. Corrosion testing was carried out on both IN 625 and Colmonoy 5 clad samples at various intervals (0, 13, 27 and 56 h) for interrogating the corrosion behavior in terms of Tafel and impedance plots along with the surface roughness examination using scanning probe microscopy. The results showed that the clad region consists of dendritic microstructure along with the segregation of interdendritic Cr-rich precipitates after solidification. These interdendritic precipitates aid in improving the hardness at the clad region. Moreover, the clad samples have better anti-corrosion characteristics because of the existence of dendritic and interdendritic phases compared to the IN 625 samples in terms of current density, polarization resistance and average surface roughness values.

ABSTRACT
In this paper, we provide Dirichlet series with periodic coefficients that have Riemann’s functional equation and real zeros of Dirichlet L-functions. The details are as follows. Let L(s, χ) be the Dirichlet L-function and G(χ) be the Gauss sum associated with a primitive Dirichlet character χ (mod q). We define

is the complex conjugate of χ and κ(χ) := (1 – χ(−1))/2. Then, we prove that f (s, χ) satisfies Riemann’s functional equation in Hamburger’s theorem if χ is even. In addition, we show that f (σ, χ) ≠ 0 for all σ ≥ 1. Moreover, we prove that f(σ, χ) ≠ 0 for all 1/2 ≤ σ < 1 if and only if L(σ, χ) ≠ 0 for all 1/2 ≤ σ < 1. When χ is real, all zeros of f (s, χ) with
