Published: October 2020

Abstract
In this paper, a laboratory-scale electrodialysis reactor with five compartment cells separated by a bipolar membrane and ion exchange membrane was assembled to remove ammonia nitrogen from landfill leachate as a pretreatment process. The effects of humic acid, magnesium ions (Mg2+) and calcium ions (Ca2+) existing in leachate on the removal efficiency of ammonium () were investigated by using simulated wastewater. The results indicate that humic acid has little impact on ammonium in the presence of an electric field. High concentrations of Mg2+ and Ca2+ in solution have a substantial impact on the removal efficiency of ammonium, but the average migration rate of the three ions is &gt; Mg2+ &gt; Ca2+ under the same current intensity, and plays a major role in electromigration for mixture electrodialysis. Therefore, ammonia nitrogen can be separated from leachate and accumulated effectively. Meanwhile, the bipolar membrane near the cathode produces alkali that is released into the base cell to promote ammonia nitrogen transformation from accumulated ammonium, which creates in-site alkaline condition for ammonia nitrogen recovery by a further stripping process. When the actual leachate collected from a local municipal sanitary landfill was employed, the reactor reached 86.17% of ammonia nitrogen removal after 3.0 h reaction. Analysis of membrane scale suggests the inhibitory effect of Mg2+ on Ca2+ migration during the initial working period of the reaction can potentially slow down the membrane scaling of the cation exchange membrane. This study provides a promising technology for the removal and recovery of ammonia nitrogen from landfill leachate.

AbstractThe mathematical model's usage in water quality prediction has received more interest recently. In this research, the potential of random forest regression (RFR), Bayesian multiple linear regression (BMLR), and multiple linear regression (MLR) were examined to predict the amount of 2,4-dichlorophenoxy acetic acid (2,4-D) elimination by rice husk biochar from synthetic wastewater, using five input operating parameters including initial 2,4-D concentration, adsorbent dosage, pH, reaction time, and temperature. The equilibrium and kinetic adsorption data were fitted best to the Freundlich and pseudo-first-order models. The thermodynamic parameters also indicated the exothermic and spontaneous nature of adsorption. The modeling results indicated an R2 of 0.994, 0.992, and 0.945 and RMSE of 1.92, 6.17, and 2.10 for the relationship between the model-estimated and measured values of 2,4-D removal for RFR, BMLR, and MLR, respectively. Overall performances indicated more proficiency of RFR than the BMLR and MLR models due to its capability in capturing the non-linear relationships between input data and their associated removal capacities. The sensitivity analysis demonstrated that the 2,4-D adsorption process is more sensitive to initial 2,4-D concentration and adsorbent dosage. Thus, it is possible to permanently monitor waters more cost-effectively with the suggested model application.
Experimental investigation of hydraulic characteristics and energy dissipation in a baffle-drop shaft
Authors: Yang Qinghua , Yang Qian 
Published: October 2020

Abstract
The baffle-drop shaft structure is usually applied in deep tunnel drainage systems to transfer shallow storm water to underground tunnels. At present, the definition of the maximum operational capacity of baffle-drop shafts is lack of scientific and reasonable analysis, and the researches on hydraulic and energy dissipation characteristics have been insufficient. In this paper, a 1:25 scale hydraulic model test was conducted to observe the flow phenomena during the discharge process, analyze the relationship between the maximum inflow discharge and the baffle parameters, and calculate the energy dissipation rate of the shaft under different ﬂow conditions. The results demonstrated that three kinds of flow regimes were presented in the discharge process: wall-impact confined flow, critical flow, and free-drop flow. The impact wave majorly brought about the energy dissipation of water on the baffle. The impingement and breakup of the inflow at the bottom of the drop shaft, as well as the reverse flow, resulted in the final energy loss. The time-averaged pressure value of the upper baffle was 1.5–3 times that of the central and lower baffles. The baffle with a design angle could effectively reduce the time-averaged pressure of the water flow acting on the baffle. The energy dissipation rate of the drop shaft decreased with the increase in the inflow discharge, and the energy dissipation rate was found to range from about 63.14% to 96.40%. The optimal size of the baffle-drop shaft with the maximum energy dissipation rate was d/B = 0.485 and θ = 10° (d, B, and θ are the baffle spacing, width, and angle, respectively).

Published: October 2020

Objective: To characterize the clinical significance of potential drug interactions and identify the targets for their minimization among adult diabetic hypertensive outpatients at Kenyatta National Hospital.
Methods: This cross-sectional study collected and analyzed data from 104 diabetic hypertensive outpatients (aged ≥18 y) at the Department of Endocrinology Outpatient Clinic of Kenyatta National Hospital from 1st May 2019 to 31st August 2019. The main outcome measure was the clinical significance of potential drug interactions and the targets for minimization. Participants’ sociodemographic data, drugs prescribed and targets for prevention of potential drug-drug interactions were extracted from patient medical records into predesigned data collection forms. Potential drug interactions were identified using the Micromedex® drug interaction checker. Data was exported to STATA® software version 13 for analysis.
Results: The study comprised predominantly females (70.2%) and the mean age was 61.6 (±10.8) years. Over 80% of patients were receiving renin inhibitors or metformin and the commonest potential drug interaction (25.0%) was antidiabetics-beta blockers. The most common potential clinical outcome of the drug-drug interaction was hyperkalemic lactic acidosis (14.4%), induced by combining enalapril with metformin, and hypoglycemia (9.6%) on concomitant use of antidiabetic and beta-blocker. Adverse clinical outcomes were mainly minimized through regular blood sugar checks (100%), blood pressure monitoring (98.1%), and minimal HbA1c (30.8%) checks as well as serum urea and electrolytes (17.3%) measurements.
Conclusion: There are potential adverse outcomes of combination pharmacologic therapies among diabetic hypertensive patients in Kenyatta National Hospital. Apart from the clinical monitoring, clinicians should be aware that diabetic hypertensive patients are likely to have serious adverse effects of drug interactions and, therefore, institute or intensify other measures such as arterial blood gases and serum electrolyte tests.

Objective: Wound care behavior among the population.
Methods: An observational survey was conducted randomly among different college students and the general population of all age groups having different professions. Survey questionnaires were prepared on google form and responses were collected by online mode. The form was designed to know the self-medication behavior among the population.
Results: The total number of participants was 332. Out of which female participants were dominated 174(52.4%) and male participants were 158(47.59%). The survey revealed that 58.73% of participants took doctor’s advice, 33.73% took self-medication, 4.22% took healthcare worker advice and, 3.31% took any other advice for treatment.
Conclusion: The survey revealed that although most of the population took doctor’s advice for the treatment of wounds but yet there is a significant population (33.73%) who took self-medication for this treatment, which should be minimized by providing awareness among them. Most of the wounds were healed within 10 d. Most of the population took medication (analgesic, antibiotic) for treatment. The use of antibiotics by self-medication is a matter of concern nowadays. As a global threat is antibiotic resistance. These drugs should be prescribed under medical supervision.

In this study, we assessed the productivity gains associated with the use of obinutuzumab in combination with chemoimmunotherapy (G-chemo) in first-line treatment among follicular lymphoma patients. Health benefits, measured as an increase in progression-free survival, were translated into productivity gains in both paid and unpaid work using gross value added as productivity measure. From 2017 to 2030, 11,870 overall progression-free years can be gained by utilizing obinutuzumab. These progression-free years correspond to undiscounted productivity gains of about €187.9 million in paid work and about €535.9 million in unpaid work. Our study shows that the benefits of the use of obinutuzumab in the first-line treatment of follicular lymphoma extend beyond clinical advantages.

Abstract— An induction motors (IM) in many industries is used because it has several advantages, such as a very simple and strong construction, the price is relatively cheap, has good efficiency, power factor is quite good, and maintenance is easier. Besides the advantages of induction motors also have disadvantages, one disadvantage of induction motors is not being able to maintain a constant speed when there is a change in load. If the load changes, the speed of the induction motor will decrease. One method of regulating the speed of an induction motor presented in this study is the regulation of an induction motor using a carrier based PWM (CBPWM) inverter with the field oriented control (FOC) technique. The estimation of rotor rotation, torque and flux is done by carrier- based PWM technique which is given input voltage and stator current. To achieve the desired flux and torque, estimation is used as feedback in the control system. In this study, it will be simulated the induction motor speed regulation with a carrier base-based inverter using Matlab. The results obtained through simulation show the length of time to reach the reference speed for speeds of 1500 rpm and 1450 rpm is around 0.45 seconds. And THD average 2,675%.

Development efforts in the vertical direction should have been better than in the horizontal direction which only requires land to the side. The emergence of new ideas certainly raises the pros and cons, most local geniuses are vertical purity, the compilation passes under the terraced infrastructure there is a feeling of flare/fatigue because it is bypassed by people. The aim of the study is to reveal the vertical relationship with the design of underpasses, and how community acceptance of underpass construction. The methodology used is complicated through interviews with Hindu scholars, Bali, which are then used as a basis for further observation for shareholders so that questionnaires can be prepared. The results of the questionnaire are data of the relationship between vertical and attitude of community acceptance towards underpass development. The data obtained were analyzed by Logistic Regression. The results of the study of vertical simplicity are local wisdoms that need to be discussed and agreed in this modern era. Furthermore, the results of the analysis show that there is a relationship between vertical purity and uneven plot intersection height, as evidenced by the acceptance of the hypothesis at the significance level ? = 0.05. The results of the analysis show "significance <?" or (0.033 <0.05), this means vertical purity, which means significant effect on underpass height design. Alternative designs also need to reduce underpass differences. Invitations are made very necessary as a legal umbrella for the design and manufacture of underpasses.
Keywords: Vertical purity, underpass, cemer/leteh, alternative design.

El objetivo del presente estudio, es estimar el impacto del programa Juntos sobre los niveles de violencia doméstica contra la mujer. Ciertamente, la violencia es un fenómeno complejo y está determinado por múltiples causas; si bien es cierto, dentro de los objetivos del programa Juntos no está prevista directamente la disminución de la violencia doméstica. Sin embargo, un grupo de estudios advierten que una de las causas de la violencia contra la mujer es por razones de carácter económico y existen tres tipos de violencia doméstica: física, psicológica y sexual. Específicamente, el programa Juntos, es un programa social dirigido a la población de mayor vulnerabilidad, en situación de extrema pobreza, riesgo y exclusión; el subsidio consiste en la entrega mensual de dinero de 100 soles. El estudio sigue una metodología cuantitativa por la necesidad de evidenciar empíricamente el impacto del programa, concretamente es la técnica de Propensity Score Matching : Nearest Neighbor Matching y la fuente de datos utilizada para el análisis es la Encuesta Nacional de Demografía y de Salud Familiar - ENDES de los años 2014 y 2015. Los resultados señalan que el programa Juntos no ha logrado reducir los niveles de violencia doméstica a un nivel de significancia de 5%, no se reporta impacto favorable del programa en la reducción de la violencia física, psicológica y sexual ya sea en forma severa o algunas veces; no obstante que el número de hogares beneficiarios se ha incrementado exponencialmente, durante los 10 años de funcionamiento. Los resultados sugieren incorporar en el componente de salud del programa Juntos la salud mental de los hogares beneficiarios para ello es importante la participación de la mujer y de su pareja, la condición o el compromiso es modificar el comportamiento de la pareja en actos o actitudes de violencia.
