Authors: Janyasupab Pakawat , Jampeetong Arunothai
Published: August 2022

Physicochemical characteristics of porous substrates (longan biochar, corn biochar, and pumice) including specific surface area (SSA), pore volume (Vp), and cation exchange capacity (CEC) were determined. Longan biochar had the highest SSA, Vp, and CEC, followed by corn biochar and pumice. Then, columns filled with each of these 3 substrates together with gravel as a control treatment, were evaluated to compare wastewater treatment efficiency under different hydraulic retention times (HRTs). Each system had been acclimatized with wastewater for 8 weeks. Then, influent and effluent were analyzed at 1, 3, 5, and 7 day intervals. Water analysis revealed that biochar-based systems showed higher dissolved oxygen (DO) development and greater removal of biochemical oxygen demand (BOD5), total suspended solids (TSS), ammonium (NH4-N), total Kjeldahl nitrogen (TKN), and nitrate (NO3-N) than pumice and gravel-based systems. Prolongation of HRT significantly increased NO3-N removal and slightly increased BOD5 and TSS removal. Both BOD5 and TSS removal in biochar-based systems after 1 day HRT was about 93–94% while they significantly increased with HRT extension to a high of 97–98%. Furthermore, NO3-N removal in biochar-based systems increased from 47–48% after 1 day HRT to 80% after 5–7 days HRT. In addition, NH4-N and TKN removal was influenced by both substrate and HRT with significant interaction between these two factors. Longan biochar-based systems, in particular eliminated almost 90% of both NH4-N and TKN and the removal efficiency improved significantly after HRT was extended. Meanwhile, both NH4-N and TKN removal were only 20–30% in the gravel-based systems and 50-60% in pumice-based system. The study suggests that longan biochar is the most effective substrate. Longer HRTs were also found to increase the efficiency of removing organic matter and nitrogen.

The thermosiphons are wickless heat pipes which work under gravity force. Different working fluids like water, engine oil, ethylene glycol are used in this equipments. Nanofluids including various nano particles are also used in the thermosiphons. In this study, deionized water (DW)/ ethylene glycol (EG) mixture based graphene nano platelet (GNP) nanofluid was charged in a thermosiphon and thermal performance analysis was performed. The mixing rate of DW:EG was 95:5 while the particle concentration was 1 %. Triton X-100 was added to the mixture as surfactant. To specify the effect of GNP, a set of experiments for both DW+EG and DW+EG+GNP nanofluid were carried out at the same operating conditions. The results show that GNPs had a positive effect on the performance of the thermosiphon. The presence of GNP in the base fluid was decreased the thermal resistance while it was increased the thermal efficiency of the thermosiphon. The maximum efficiency value was reached as 57.1 % when the nanofluid used. At the same condition, the efficiency was 49.5 % when the working fluid was DW+EG mixture.
OBSERVER BASED SLIDING MODE CONTROLLER DESIGN FOR POSITION CONTROL OF A SERVO SYSTEM HAVING UNCERTAINTIES AND DISTURBANCES
Authors: ÖNEN Ümit
Published: August 2022

Servo systems are used extensively in many industrial applications that require precise position control. However, parameter uncertainties, matched and unmatched disturbances encountered in most of these applications adversely affect the controller performance. Therefore, in industrial control applications, robustness is at least as important as precision. In this study, an Extended State Observer-based Sliding Mode Controller (GDGKKK) design is presented for precise position control of a rotary servo system having parameter uncertainties and disturbance input. The performance of the proposed controller has been tested by performing simulation studies for five different uncertainty and disturbance input scenarios and compared with the traditional Sliding Mode Control (SMC) and Proportional Derivative (PD) control to evaluate its effectiveness. The mathematical model of the Quanser SRV02 rotary servo unit was used in the simulation studies in MATLAB/Simulink software. The simulation results show that the PD control is very sensitive to load changes and disturbances and while the traditional SMC control is insensitive to load changes and matched disturbances, it is sensitive to mismatched disturbances. On the other hand, the results clearly showed that the proposed GDGKKK controller offers extremely successful disturbance rejection performance against both load changes and matched and unmatched disturbances.

Today, energy is accepted as the most indicator of economic development. However, the use of fossil fuels as energy sources is caused the depletion of the ozone layer, global warming and climate change. Therefore, using renewable energy systems called sustainable energy is a remarkable step in terms of both minimizing fossil fuel consumption and the effects of the environment on human health. In this study, solar chimneys, one of the solar-assisted electricity generation systems among renewable energy sources, are analyzed. A solar chimney power plant (SCPP) has been designed by considering the environmental conditions of the Iskenderun region in Hatay province. The facility consists of collector, chimney, turbine and generator. Sun rays entering the solar chimney from the transparent collector heat the air. The heated air leaves the solar chimney with the effect of the pressure difference. The turbine is placed in the chimney section where the air velocity is high. The mechanical power obtained from the turbine is converted into electrical energy through the generator. The energy source of the system is the sun, and the working fluid of the system is air. In the calculations, the average irradiance value of the Iskenderun region was used and optimization of the designed SCPP was made using these values. The optimization of the SCPP designed for the Iskenderun region is performed using numerical analysis programs.

Introduction: PEFR is considered as the simplest index of pulmonary function. Ventilatory function tests like PEFR provide a better understanding of the changes in the lungs from a diagnostic viewpoint. It is effort dependent and reflects mainly the calibre of the bronchi and larger bronchioles, which are subjected to reflex bronchoconstriction. Objective: To study the variations in the PEFR with various factors with respect to age, body mass index, blood pressure and heart rate among males and females patients. Methods: This was a cross-sectional study conducted at Department of Medicine, Shaheed Tajuddin Ahmad Medical College Hospital, Gazipur, Bangladesh from January to December 2020 among young male and female subjects. The subjects with no history of cardio, availability & capacity to cooperate adequately, non- smokers; and no history of any drug intake which could affect the lung functioning were included in the study. PEFR was measured with the subject comfortably seated during the same time of the day for all subjects. It was determined in litres/minute with the help of “The Peak”, Individualised Peak flow meter from Multispiro Inc. Results: Out of the total subjects 121 subjects, 45.4% were ≤18 years followed by 19-20 (42.1%) and >20 (12.3%). There were 37.1% males and 62.8% females. PEFR was found to be significantly (p=0.0001) higher among males compared to females in all the age groups. PEFR increased with increasing age in both male and female subjects. PEFR was found to be significantly (p<0.0) higher among males compared to females in the entire body mass index (BMI) category. PEFR increased with increasing BMI in both male and female subjects. Conclusion: PEFR is higher among male than female subject. Also, PEFR was higher in males than females in all the age groups and BMI status. The effects of various factors like age, height, weight, BSA and BMI on the PEFR values have also been discussed in this study. PEFR increases with increase in age and BMI in both male and female subjects.

Authors: Santos Mesquita Roseane , Teixeira dos Santos Andréia , Lucini Marizete
Published: August 2022

Este artigo discute o racismo estrutural no contexto do bicentenário da independência do Brasil, no âmbito das comunidades remanescentes de quilombos como alvos de uma dupla discriminação que se efetiva em relação ao ser negro e ao ser quilombola. Nossa reflexão intenciona evidenciar que os processos discriminatórios fundados no racismo e na diferenciação de classe permanecem operantes, mesmo após o reconhecimento desta coletividade na Constituição Federal de 1988 e, posteriormente, no Decreto Presidencial n° 4887 de 2003 e da aprovação de Diretrizes Curriculares para a Educação Escolar Quilombola (2012). A partir de uma reflexão teórico-conceitual, apresentamos um histórico sobre o conceito de quilombo e o pertencimento identitário dos sujeitos quilombolas, apontando à importância dos atos legais pactuados no reconhecimento e concessão de direitos para estas comunidades.
