Authors: Cahyani Intan Martha , Anggraini Intan Aprilia Choirul , Sari Melvina Findyana , Tamara Sita , Zaemonah Siti 
Published: January 2019

Peppermint oil adalah minyak atsiri yang diperoleh dengan destilasi uap dari bagian di atas tanah tanaman berbunga Mentha Piperita Linne. Kandungan utama dari peppermint oil adalah menthol (35-55%) yang mempunyai aktivitas sebagai antibakteri dan penyegar mulut. Hal inilah yang menjadikan dasar untuk diformulasikannya peppermint oil dalam sediaan edible film sebagai penyegar mulut dengan menggunakan pati yang merupakan pembentuk film yang baik karena mengandung amilosa cukup tinggi. Amilosa bersifat tidak larut dalam air dingin tetapi menyerap sejumlah besar air dan mengembang. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan jenis pati pada karakteristik fisik sediaan edible film peppermint oil. Pati yang digunakan berasal dari pati gandum, pati garut, pati jagung, dan pati kentang. Penelitian ini dilakukan dengan konsentrasi 025% tiap pati. Uji karakteristik fisik meliputi organoleptis, waktu hancur, tensile strength, percentage elongation, young’s modulus, dan percentage LoD. Uji tanggapan pengguna meliputi aspek warna, bentuk, bau, dan rasa serta uji Angka Lempeng Total. Hasil penelitian menunjukkan bahwa penggunaan jenis amilum yang berbeda berpengaruh signifikan pada karakteristik fisik dan tanggapan pengguna. Peningkatan kadar amilosa pada pati meningkatkan waktu hancur, tensile strength, young’s modulus, dan menurunkan percentage elongation serta percentage LoD dari edible film peppermint oil antar formula. Hasil uji Angka Lempeng Total memenuhi syarat yaitu < 104 koloni/g.

The rupture of the Fundão mine dam in Mariana municipality, Minas Gerais State, Brazil, spilled the tailings across the Doce River basin. These tailings, composed of residues discarded from the beneficiation of iron ore, are rich in SiO2 and Al2O3, as well as some ether amine compounds and NaOH. The aim of this study was to assess the distribution of these sediments, as well as their effect on the riparian zones reached, as compared with preserved sites. Sediment deposition in the river resulted in a morphological change from a meandering profile to a braided aspect. The nutrient and mineral content (P, K, Ca, Mg, Cu, Fe, Mn, Zn, and NO3−) and soil organic matter of the sediments were depleted, whereas NH4+, Na, and pH increased. A random presence of ether amines in the sediments was confirmed by quantitative and chromatographic analyses, with concentrations ranging from 0 to 57.8 mg kg−1; Na reached values as high as 150 mg kg−1. The impact of the dam tailings on biota was assessed by estimating total microbial biomass (phospholipid fatty acids), which were depleted in sediments relative to soils from preserved sites. Overall plant mortality, as well as a low resilience capacity, were also observed. Ether amines and Na present in the sediments had a strong toxic effect in the environment. Identification of these substances as the main impact factors will help guide future remediation efforts.Core Ideas
Dam disruption caused changes in the fluvial profile and nutrient depletion in the sediment.
Depletion of microbial biomass in the sediment and plant mortality occurred.
Despite the low organic matter and NO3− in the sediment, NH4+, Na, and pH increased.
The environmental impact was attributed to the increase in NH4+, pH, and Na.
Ether amine and Na from the dam are the main toxic factors.

Abstract
In this study, a novel poly ligand exchanger-Zn(II)-loaded resin was designed to effectively remove ammonia-nitrogen (NH3-N) from wastewater. The surface morphology and structure of the Zn-loaded resin were characterized using scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) and Fourier transform infrared spectroscopy (FTIR), respectively. SEM shows the surfaces of the Zn(II)-loaded resin were rough and nonporous and EDS demonstrated that Zn2+ was loaded onto the resin successfully. In addition, the combination form of Zn(II) with NH3-N adsorption reagent was revealed by FTIR spectra; the complex could be R-N-R-O-Zn-O-R-N-R and R-N-R-(O-Zn)2. The kinetics and equilibrium of the NH3-N adsorption onto the Zn(II)-loaded resin has been investigated. The effects of pH, reaction time, and temperature on NH3-N removal from wastewater by Zn(II)-loaded resin were investigated, and the results showed that the maximum adsorption capacity reached 38.55 mg/g at pH 9.54 at 298 K in 240 min. The adsorption ability of the modified resin decreased with an increase in temperature. Moreover, the NH3-N adsorption followed a pseudo-second-order kinetic process. The kinetic data demonstrated that the adsorption process might be limited by a variety of mechanisms. The study can provide the scientific foundation for the extensive application of a novel poly ligand exchanger-Zn(II)-loaded resin to remove NH3-N from wastewater.

Abstract
The choice of the spatial submodel of a water resource recovery facility (WRRF) model should be one of the primary concerns in WRRF modelling. However, currently used mechanistic models are limited by an over-simplified representation of local conditions. This is illustrated by the general difficulties in calibrating the latest N2O models and the large variability in parameter values reported in the literature. The use of compartmental model (CM) developed on the basis of accurate hydrodynamic studies using computational fluid dynamics (CFD) can take into account local conditions and recirculation patterns in the activated sludge tanks that are important with respect to the modelling objective. The conventional tanks in series (TIS) configuration does not allow this. The aim of the present work is to compare the capabilities of two model layouts (CM and TIS) in defining a realistic domain of parameter values representing the same full-scale plant. A model performance evaluation method is proposed to identify the good operational domain of each parameter in the two layouts. Already when evaluating for steady state, the CM was found to provide better defined parameter ranges than TIS. Dynamic simulations further confirmed the CM's capability to work in a more realistic parameter domain, avoiding unnecessary calibration to compensate for flaws in the spatial submodel.
The inhibitory effect of inorganic carbon on phosphate recovery from upflow anaerobic sludge blanket reactor (UASB) effluent as calcium phosphate

Published: January 2019

AbstractAfter treatment of the wastewater from the potato processing industry in an upflow anaerobic sludge blanket reactor (UASB) the effluent is rich in phosphate and dissolved inorganic carbon (IC). Increasing the pH of the UASB effluent with NaOH to precipitate phosphate as calcium phosphate leads to contamination with magnesium phosphate. Increasing the pH with Ca(OH)2 had a positive effect on phosphate precipitation, but after increasing the pH with Na2CO3 no precipitate was formed. After prior nitrification of the UASB effluent to remove IC, less NaOH was needed to increase the pH and the ions precipitated in a ratio that agreed with calcium phosphate formation. When the pH of the nitrified effluent was increased with Na2CO3 neither calcium nor phosphate precipitated. This inhibitory effect of IC on phosphate precipitation as calcium phosphate could not be derived from the saturation indexes calculated by the geochemical modelling program PHREEQC.

Published: January 2019

Introduction:
Implants have turned out to be a well-established therapy in dental practice for the replacement of missing teeth and restoration of function.
Peri-implant disease denotes the inflammatory condition of surrounding soft and hard tissues.
Two terminologies are covered under the impression of peri-implant pathology; peri-implantitis and mucositis. Peri-implant mucositis is a reversible inflammatory process limited to soft tissues around an implant. Peri-implantitis is an inflammatory condition of hard and soft tissue around the dental implant.

Microbial Etiology:
Bacterial infections are the most common cause of peri-implantitis. It is a variable poly-microbial infection, although generally dominated by Gram-negative anaerobic bacteria Anti-infective therapy should be included in the treatment regime, while treating the peri-implant disease. Antimicrobial therapy includes local debridement, antibiotic therapy and surface decontamination of the implant.

Conclusion:
The current article gives a detailed overview of microbial etiology, antimicrobial therapy and its limitations for the treatment of peri-implant Pathology.

Published: January 2019

Introduction:
Parotid gland swelling, caused by many pathological conditions, has also been reported to be a possible side effect of the use of chlorhexidine mouthwash. This adverse reaction to chlorhexidine mouthwash is, however, extremely rare and very few cases of parotid gland swelling due to chlorhexidine mouthwash have been reported in the literature.

Case Description:
This report describes the clinical management of unilateral parotid swelling caused by chlorhexidine mouthwash.

Methods:
A patient presented with left parotid gland swelling after using chlorhexidine mouthwash for three days following sinus augmentation on the contralateral side of the maxilla. Diagnosis of parotid gland swelling due to rinsing with chlorhexidine was formulated after anamnesis, clinical examination, radiographs and ultrasound of the gland excluded other pathological conditions. The patient was subsequently advised to stop rinsing. However, on the evening of the same day, swelling increased and the patient presented to an emergency department where a single intravenous dose of methylprednisolone was administered.

Results:
After seven days, parotid swelling decreased significantly and after three weeks had completely disappeared.

Conclusion:
Although unilateral or bilateral parotid gland swelling related to the use of chlorhexidine mouthwash is an uncommon adverse event, it must be suspected after other organic or infective conditions have been excluded. The precise pathogenic mechanism has not yet been determined and further studies should be carried out to better understand the pathophysiology of this uncommon phenomenon.

Published: January 2019

En este artículo se analiza la precariedad laboral por grupos ocupacionales de trabajadores asalariados en el Estado de México, en 2005 y 2015. Se utilizó la técnica estadística del análisis por conglomerados, para agrupar a dichos trabajadores en cuatro grupos de precariedad: alto, medio, bajo y no precario, con base en la Encuesta Nacional de Ocupación y Empleo del segundo trimestre de 2005 y 2015. La población objetivo se restringe a los trabajadores asalariados, y el análisis de la precariedad laboral se realiza con variables generales, sin profundizar en casos específicos, a través de la metodología cualitativa. La originalidad aquí es que el análisis de la precariedad se hizo en un contexto regional, y también que es un estudio comparativo entre 2005 y 2015. Uno de los resultados más relevantes es la concentración de los trabajadores asalariados en los grupos extremos: precario alto y no precario, lo que muestra la polarización laboral en el mercado de trabajo del estado.

Authors: Hayduk Nelli 
Published: January 2019

The article analyzes and summarizes the views of Ukrainian and foreign linguists concerning the language structure and conceptual world pictures peculiarities. The paper focuses on the existence of general and specific in language. The role of culture in the formation and evolution of national world pictures and the influence of the national language on the formation of the speakers’ worldview are reviewed. The problem of national specificity of the language is analyzed not only in terms of the language and thinking, language and reality relation, but also in terms of the correlation of language and culture, their interaction and interplay. Culture is presented in the study as a complex phenomenon, in the framework of which the peculiarities of knowledge of reality are fixed by one or another lingua-cultural community. The language world picture is considered as one of the main components of culture and as a means of transferring lingua-cultural peculiarities.
