This paper presents the study of water supply dams in Malaysia using the Storage Yield Reliability (SYR) model. The model is a linearized regressed equation with five independent variables comprising of hydrological and physical properties of the reservoir system, namely dam inflows and its statistical moment properties, reservoir storage capacity, and designated return periods or probability of non-exceedance of low flow. A total of twenty eight water supply reservoir schemes were selected for comparison in this study. Seventeen and eleven reservoirs respectively operated under direct supply (DS) and regulating reservoir (RR) modes. The estimated SYR yields were compared to the known water treatment plant (WTP) capacities of these reservoir schemes. Out of five variables, catchment area (indirectly proportionate to dam inflows) and storage capacity are positively correlated to the estimated SYR yields. The SYR model adopted in this study could provide quick yield assessment for all the twenty eight DS and RR reservoir schemes in Malaysia. In summary, the multivariate regression model SYR approach can be used as the first screening process of DS and RR operation mode reservoir yield estimation in Malaysia.

Activated sludge process is one of the effective methods in biological wastewater treatment and the impact of oxygen transfer through aeration process has the most important breakthroughs as it served as the largest consumer in the treatment. Aeration is an energy demanding process. Oxygen transfer into an activated sludge is a very challenging issue in the field of multiphase flows. Apart from the physical mass transfer phenomena between gas, liquid and solids phases, the transport mechanisms are also overlapped by time and temperature, varying microbial activity, impurity loads, adsorption and desorption processes. Oxygen uptake rate (OUR) for microbial population in the activated sludge system is important parameter to determine the amount of oxygen consumed during aerobic heterotropic biodegradation in the system. Evaluation of specific oxygen uptake rate (SOUR) and the volumetric mass transfer coefficient (KLA) of oxygen for three different wastewater treatment processes, namely conventional activated sludge (CAS), oxidation ditch (OD) and sequencing batch reactor (SBR) treating municipal wastewater in Kuala Lumpur have been carried out. In-situ and ex-situ measurement of pH, dissolved oxygen (DO), temperature, MLSS and MLVSS were carried out. In the activated sludge treatment, very low concentration of dissolved oxygen may cause the wastewater to turn septic resulting in death of bacteria or in active due to unstable anaerobic conditions. Conversely, an excessive dissolved oxygen may result to high energy and high 25 operating cost. Higher flowrate may also cause dissolved oxygen to rise, reducing the quality of sludge and slowing the denitrification process in the system. Results revealed that the OUR for SBR, OD and CAS were 9.582 mg O2 /L/hr, 10.074 mg O2 /L/hr and 13.764 mg O2 /L/hr, respectively. Low oxygen uptake rate indicates a low rate of microbial respiration. By computing the OUR, the mass transfer coefficient could be evaluated. It should be noted that among the treatment system in this study, the conventional activated sludge shows the highest mass transfer coefficient and specific oxygen uptake rate of 2.038 hr-1 and 15.605 mg O2 /g MLVSS/hr, respectively. Improving the oxygen transfer rate and reducing aeration in the system could achieve a cost-effective aeration system.

Magnetic Levitation System (MLS) is a nonlinear system and it is used extensively in many areas. The system's goal is to use the non-contact principle to magnetize the coil and cause the objects to float to a specific height. The magnetic force and the current flowing through the coil have a nonlinear relationship. In this paper first design of the backstepping controller is done to attain the wanted floating in presence of system related uncertainties and system behavior is witnessed. Then a Sliding Mode Controller (SMC) based on backstepping procedure is formulated. The control gains in this controller are designed in such a way that the characteristics polynomial whose coefficients are control gains is strictly Hurwitz and the closed loop system's asymptotic stability is assured. Simulations are performed and the magnetic ball tracking is observed considering step signal as reference in presence of disturbances. More accuracy is observed in terms of following the reference by the magnetic ball when it is used Sliding Mode Controller based on Backstepping technique instead of backstepping controller by considering pulse type disturbance. By simulation and analyzing results it is confirmed that the proposed control strategy is more effective.

Filosofía y Literatura: El rol de la distinción phýsis y tékhne en la construcción de los géneros literarios
Authors: Castillo Merlo Mariana
Published: November 2021

En ¿Qué es un género literario? (1989), J.-M. Schaeffer acusa a Aristóteles de una ambigüedad inicial que habría condicionado el análisis de los géneros literarios a lo largo de su historia. Teniendo en cuenta algunas lecturas “literarias” y “filosóficas” de Poética, en este trabajo pretendo analizar las perspectivas naturalista-esencialista, histórica-analítica y normativa desde las cuales Aristóteles lleva adelante su empresa. En tal sentido, evaluaré, por un lado, los alcances de dichas perspectivas en dos momentos particulares de la Poética (1447a-1448b y 1448b-1449a) y, por otro, la manera en que cada una de ellas pone en juego la distinción aristotélica entre phýsis y tékhne.

En este artículo indagaremos en la perspectiva heideggeriana de la corporalidad a partir de sus consideraciones de los gestos y las figuras hápticas, tanto en elaboraciones en torno a Sein und Zeit como en sus especificaciones de los Zollikoner Seminare. En este marco distinguiremos el carácter secundario de sus consideraciones del cuerpo físico y algunas de sus implicancias. Para ello analizaremos sus elaboraciones en torno a la praxis y las relaciones con el mundo circundante para circunscribir su tratamiento de los índices corporales o las figuras manuales en su trabajo de 1927. Luego articularemos sus consideraciones sobre los gestos corporales en sus seminarios de 1960, de tal modo que permita dar cuenta de alcances y límites de estas elaboraciones.

Published: November 2021

The aim: To study morphometric and electron microscopic changes in the parenchyma of rat lymph nodes under the action of sodium glutamate and its correction by orlistat. Materials and methods: The article presents and analyzes the data of an experimental study conducted on 66 white male rats and females of reproductive age. Experimental animals are divided into 4 groups. Results: After six weeks of exposure to monosodium glutamate, there was a significant decrease in the relative area of the cortical substance in the lymph nodes of white male and female rats by 11.95% and 9.31% and, respectively, an increase in the relative area of the medullary substance by 18.76% and 14.7% in compared with an intact group of animals. After six weeks of sodium glutamate and the next six weeks of the standard diet of vivarium and orlistat, the relative area of the cortical substance in the lymph node parenchyma was 2.55% and 0.38% more than the parameters of the intact group of animals, respectively. Accordingly, the relative area of the medullary substance decreased and was 4.01% and 0.59% less compared to the intact group of animals. Conclusions: Electron microscopic examination showed that monosodium glutamate causes changes in the parenchyma of the lymph nodes as in a high-calorie diet. The introduction of orlistat (xenical) leads to a partial restoration of the structural organization, and hence the function of this organ.

Published: November 2021

The aim: This study was aimed at analyzing the impact of preventive therapy for pregnant women at a high risk to develop preeclampsia on the normalization of the mechanisms of decidual macrophage polarization.
Materials and methods: The methodology was designed to obtain data on the content of pro- and anti-inflammatory cytokines and indicators of nitric oxide and arginase metabolism in cervical mucus. The ration between M1 / M2 decidual macrophages in the placenta was determined by applying immunohistochemical methods. The effectiveness of the proposed therapy for the secondary prevention of preeclampsia (metformin, vitamin D3 and corvitin) was evaluated.
Results: Pregnant women with preeclampsia showed the imbalance between pro- and anti-inflammatory cytokines in favour of TNF-α and INF-γ under the decrease in IL-10 that results in an imbalance in the activity of enzymes regulating L-arginine metabolism, with increased iNOS activity and decreased arginine activity. In the placentas of the pregnant women with preeclampsia, in contrast to the healthy pregnant women, M1 decidual macrophages are found as predominant. The women, who received the course of the preventive therapy with metformin, vitamin D3 and corvitin, showed a decrease in the concentration of pro-inflammatory cytokines and an increase in anti-inflammatory cytokine IL-10, normalization of the balance between iNOS and arginase activity, and the normalization of the M1 / M2 macrophages ratio.
Conclusions: Normalization of the balance between pro- and anti-inflammatory cytokines, iNOS and arginase activity in cervical mucus, the ratio between decidual M1 and M2 macrophages as results of the therapy proposed reduce the incidence of preeclampsia and associated complications.

The prevalence of obesity is growing at alarming rate worldwide. Obesity has reached the proportion of a global epidemic in both developed and developing countries. Growing number of obese patients with atrial fibrillation requires a closer look at how excessive body fat leads to AF. Excessive adipose tissue is the source of many cardiovascular diseases, like hypertension, ischemic heart disease, and arrhythmias such as atrial fibrillation. The prevalence of atrial fibrillation in the general population is estimated at 1-2%. Obesity and overweight occur in 25% of patients with AF. Pathophysiology of obesity and the relationship between atrial fibrillation, diabetes, obstructive sleep apnea and metabolic syndrome are presented in this article as well as the benefit of bariatric surgery in qualifying patients. Paroxysmal AF and its risk factors should be carefully assessed in all patients referred for bariatric surgery. Proper diagnosis allows physicians to introduce appropriate anticoagulant prophylaxis, and significantly lower complication rate. Antiarrhythmic, respiratory, and metabolic therapy should also be considered in preoperative and postoperative care.
