Planting trees in mining zones for post-mining rehabilitation is of great interest. Therefore, it is important and necessary to study the current state of the air, water, and soil environment in the mine exploited area. Therefore, this article studied and assessed the environmental state in Tan Rai bauxite mining area at Bao Lam district, Lam Dong province through the environmental components of air, water and soil, as a basis for selection of suitable crops for post-mining rehabilitation. The research result showed that the air quality in the bauxite mining area met the standard 3733/2002/QĐ-BYT. Almost monitoring parameters of surface water and wastewater is within the allowed threshold of Vietnam standards. However surface water had a sign of TSS and COD pollution (TSS and COD at the Danos stream after the received point of wastewater from No.6 tailing lake were 1.6 times and 1.07 times higher than those in standard). Ground water was polluted by Coliform (20-63,3 times over standard) and cation NH4+ (1.1-1.5 times over standard); Soil in exploiting region was strongly impacted, soil profile has changed, red-yellow soil dominated, soil fertility is pretty high, pHH20 and pHKC were from acid to neuter. This studied environment state is very suitable for planting pine and acacia. These results will be useful references, as a basis for orientation of post-mining rehabilitation.

Published: September 2020

Treating ammonium pollution in ground water by natural zeolite after being modificated to the Na-form (Z-Na) is the new way of research that scientists interested in. The experiment results showed that, at pH 6, the efficient of treating ammonium in ground water is the highest. The efficient of treating increase rapidly in the first 5 minutes and remain stable after that. Higher concentration of the Z-Na will increase the treating coefficient of the process. With a water sample that has CN-NH4+=27 mg/L at first, using CZ-Na=13g/L and after 5 minutes, the concentration of ammonium in water was declined to 1mg/L, passed the Vietnamese standard for ground water (QCVN 09:2015-MT/BTNMT). The treating coefficient is 96.30%, the adsorption capacity is 2.07 mg N-NH4+/1g Z-Na. The loaded Z-Na was regenerated using 2g/L NaOH solution, the ammonium recovery ratio exceeded 92%. This means the reuse of Z-Na for ammonium adsorption is very high. The results of the experiment with groundwater samples in Phu Xuyen district, Ha Noi have a concentration of 53 mg/L. In conclusion, Z-Na material is perfectly fit for purpose of treating ammonium in ground water because of it low price, safety, easily to imitate and high efficiency.
Xử lí ô nhiễm amoni trong nước ngầm bằng vật liệu zeolite tự nhiên được biến tính bằng muối ăn (Z-Na) là một hướng nghiên cứu mới, được các nhà khoa học rất quan tâm. Kết quả thí nghiệm cho thấy, tại pH 6 thì hiệu quả xử lí amoni trong nước là tốt nhất. Hiệu quả xử lí amoni trong nước tăng rất nhanh trong 5 phút đầu tiên xử lý. Càng tăng nồng độ Z-Na thì hiệu quả xử lí amoni càng cao. Với dung dịch nước ban đầu có nồng độ amoni tính theo nitơ (N-NH4+) nhỏ hơn 27 mg/L và nồng độ vật liệu Z-Na sử dụng là 13g/L thì nước sau xử lí có nồng độ nhỏ hơn 1mg N-NH4+/L, đạt QCVN 09-MT:2015/BTNMT, hiệu suất xử lí đạt 96,30%, dung lượng hấp phụ cực đại đạt 2,07 mg N-NH4+/1g Z-Na. Vật liệu Z-Na sau khi xử lý được nghiên cứu giải hấp bằng dung dịch NaOH với nồng độ 2g/L cho thấy hiệu quả giải hấp đạt 92% lượng amoni được hấp phụ. Điều này chứng tỏ khả năng tái sử dụng của vật liệu Z-Na cho hấp phụ amoni là khá cao. Kết quả nghiên cứu đã được thử nghiệm xử lý với mẫu nước ngầm tại huyện Phú Xuyên, Hà Nội có nồng độ N-NH4+ là 53 mg/L. Vì vậy, vật liệu Z-Na hoàn toàn có thể ứng dụng vào thực tiễn để xử lý amoni trong nước ngầm rất an toàn, dễ thực hiện và hiệu quả cao.
„Thank you for not smoking“ - Zur Gouvernementalität des Rauchens
Authors: Lang Katarina 
Published: September 2020

In the present work a try is made to make the governmentality of Foucault accessible for analytics in the area of media education. The centre of attention is the (juvenile) smoking prevention. In an introducing part the concept of governmentality is placed and systematically envolved in accordance with the history of Foucaults work. An aggravation of the contemporary neoliberal conditions and the rationalities established in the health-care sector follows. That the 'history of smoking' features a genealogical dimension of the continously proceeding problematization reveals alongside the question of repressive mechanisms of power about smoking. With the tools developed during the process of this presentation it is conclusively expected to systematically take two smoking prevention documents of the Federal Centre for Health Education into account to illustrate the power of the medial staging as a melange of truth, subjectivization and self-leadership. In der vorliegenden Arbeit wird der Versuch unternommen, den Foucaultschen Gouvernementalitätsansatz für Analytiken im Feld der Medienpädagogik aufzuschließen. Im Fokus der Darstellung steht dabei der Bereich der Raucherprävention. In einem einführenden Teil wird das Konzept der Gouvernementalität innerhalb der Werkgeschichte Foucaults platziert und systematisch entfaltet. Hieran schließt sich eine Zuspitzung auf die gegenwärtigen neoliberalen Verhältnisse und die im Gesundheitsbereich etablierten Rationalitäten an. Dass die Geschichte des Rauchens eine genealogische Dimension der stetig voranschreitenden Problematisierung aufweist, wird entlang der Frage nach repressiven Machtmechanismen um das Rauchen deutlich gemacht. Mit den so im Verlauf der Darstellung entwickelten Werkzeugen werden abschließend zwei an Jugendliche gerichtete Raucherpräventionsschriften der Bundeszentrale für gesundheitliche Aufklärung systematisch in den Blick genommen, um so die Macht der medialen Inszenierung als Melange von Wahrheit, Subjektivierung und Selbstführung aufzuzeigen.
Highly efficient broadband silicon nitride polarization beam splitter incorporating serially cascaded asymmetric directional couplers

Published: September 2020

The implementation of a polarization beam splitter (PBS) on a silicon nitride platform remains challenging owing to its relatively low index. We therefore propose a silicon nitride PBS that exploits serially cascaded asymmetric directional couplers (ADCs), leading to a high polarization extinction ratio (PER) over a broad bandwidth. The ADC spatially routes incident light through polarization-selective mode coupling under a small footprint of 112 µm. The proposed PBS does not require an active phase control. It is thus effectively realized via a single-step lithography process. The measured transverse-electric and transverse-magnetic PERs were determined to be above 23 dB and 10 dB over an 80-nm bandwidth, respectively, spanning

. The proposed device is thus anticipated to play a key role in providing polarization diversity in photonic-integrated circuits.

O aumento da utilização de medicamentos em função do desenvolvimento de novos fármacos aliado à automedicação, levam a maior formação de resíduos, que acarretam em danos ao meio ambiente e à prejuízos na saúde da população. Com isso, o objetivo do presente trabalho foi avaliar os medicamentos coletados pelo Programa Descarte Consciente nos municípios de Jaraguá do Sul e Corupá- SC no período de um ano, além de conscientizar a população sobre o descarte correto e a automedicação. Para isso, foram realizadas palestras nas UBS e Centro de Idosos dos Municípios para promover essa conscientização. Após a realização das Copalestras, foram disponibilizadas caixas coletoras de medicamentos que ficaram à disposição da população. Após o recolhimento os medicamentos foram avaliados quanto ao seu nome, quantidade, forma farmacêutica, tarja, data de validade e classificados conforme ATC. Os resultados encontrados foram divulgados para a população na forma de palestras, com o objetivo de conscientização. Foram obtidas 7.528 unidades totais, com destaque para tuberculostáticos(25,75%), anti-hipertensivos (10,66%), anticoncepcionais orais (8,42%), analgésicos (5,36%) e anti-infl amatórios (3,22%). A maior quantidade das classes de medicamentos descartados pode estar associada a uma maior utilização dos mesmos pela população, fornecimento pela rede pública, uso irregular ou falta de adesão ao tratamento. Conclui-se que, a análise dos medicamentos descartados pode contribuir para uma melhor compreensão dos fatores que podem levar ao descarte excessivo bem como podem auxiliar em campanhas de conscientização quanto ao prejuízo ambiental e os danos que um descarte inadequado desses medicamentos pode causar à saúde da população.

The intervention method is a time series model which could be used to model data with extreme fluctuation whether up or down. Stock price return tend to have extreme fluctuation which is caused by internal or external factors. There are two kinds of intervention function; a step function and a pulse function. A step function is used for a long-term intervention, while a pulse function is used for a short-term intervention. Modelling a time series data needs to satisfy the homoscedasticity assumptions (variance of residual is homogeneous). In reality, stock price return has a high volatility, in other words it has a non-constant variance of residuals (heteroscedasticity). ARCH (Autoregressive Conditional Heteroscedasticity) or GARCH (Generalized Autoregressive Conditional Heteroscedasticity) can be used to model data with heteroscedasticity. The data used is stock price return from August 2008 until September 2018. From the stock price return data plot is found an extreme fluctuation in September 2017 (T=110) that is suspected as a pulse function. The best model uses the intervention pulse function is ARMA([1,4],0) (b=0, s=1, r=1). The intervention model has a non-constant variance or there is an ARCH effect. The best variance model obtained is ARMA([1,4],0)(b=0, s=1, r=1)–GARCH(1,1) with the AIC value is -205,75088. Keywords: Stock Return, Intervention, Heteroscedasticity, ARCH/GARCH

Authors: Andriyani Mega Fitria , Hoyyi Abdul , Yasin Hasbi 
Published: September 2020

The Generalized Space Time Autoregressive (GSTAR) model with Seemingly Unrelated Regression (SUR) estimation method or often called GSTAR-SUR is more efficient to be used for residual correlation than Ordinary Least Square (OLS) estimation method. The SUR estimation method utilizes residual correlation information to improve the estimated efficiency resulting in a smaller standard error. The purpose of this research is to get the GSTAR-SUR model according to Consumer Price Index (CPI) data in four regencies or cities in Central Java namely Purwokerto, Surakarta, Semarang, and Tegal. Based on the assumed white noise assumption, the smallest MAPE and RMSE averages, the best model chosen in this research is the GSTAR-SUR(11)I(1) model with the heavy of normalized cross-correlation with the average MAPE value of 0.4455% and RMSE value of 0.80582. The best model obtained explains that the CPI data in Purwokerto, Semarang, and Tegal not only influenced by the previous time but also influenced by the locations. Meanwhile, the CPI data in Surakarta is only influenced by the previous time, but it is not affected by other locations. Keywords: SUR, OLS, Consumer Price Index

Multiple Linear Regression can be solved by using the Ordinary Least Squares (OLS). Some classic assumptions must be fulfilled namely normality, homoskedasticity, non-multicollinearity, and non-autocorrelation. However, violations of assumptions can occur due to outliers so the estimator obtained is biased and inefficient. In statistics, robust regression is one of method can be used to deal with outliers. Robust regression has several estimators, one of them is Scale estimator (S-estimator) used in this research. Case for this reasearch is fish production per district / city in Central Java in 2015-2016 which is influenced by the number of fishermen, number of vessels, number of trips, number of fishing units, and number of households / fishing companies. Approximate estimation with the Ordinary Least Squares occur in violation of the assumptions of normality, autocorrelation and homoskedasticity this occurs because there are outliers. Based on the t- test at 5% significance level can be concluded that several predictor variables there are the number of fishermen, the number of ships, the number of trips and the number of fishing units have a significant effect on the variables of fish production. The influence value of predictor variables to fish production is 88,006% and MSE value is 7109,519. GUI Matlab is program for robust regression for S-estimator to make it easier for users to do calculations.
