Published: May 2017

The current researches are lack of structural and quantitative analysis on network opinion coping strategies, thus, they cannot provide practical and operational practices in dealing with network opinion. As echoing to the deficits of the research and based on Chinese situations, this
paper proposed six stages model of network opinion on public events, that is brewing stage, outbreak stage, diffusion stage, iteration stage, regression stage and long-tail stage. Then, knowledge element based descriptive model were put forward by adopting the theory of “situation-response”
decision model and the method of knowledge engineering theory. And finally, the cross-case dynamic evolutionary analysis were carried out in terms of public emergencies and the results showed that the two proposed models were effective in describing the events changes and the dynamic evolutionary
characteristics of government’s response capability, which indicate that they can provide government with some operational suggestions in coping with network opinions.

Classification for Microarray Data Based on K-Means Clustering Combined with Modified Single-to-Noise-Ratio Based on Graph Energy
Authors: Yu Lujing , Zhang Yusen , Jian Guiqian , Gutman Ivan
Published: May 2017

This paper proposes a new classification for microarray data which utilizes K-means clustering combined with modified single-to-noise-ratio based on graph energy (SNRGE) method. This method is employed to select a small subset of characteristic features from DNA microarray data.
Comparing with the single-to-noise-ratio (SNR) method proposed by Golub, it demonstrates that the SNRGES outperforms SNR method. SNRGE obtains significant improvement on the classification result via SNRGES in contrast with other SNR formulas, and the result shows that the use of SNRGE formula
is critical in eliminating irrelevant features. As compared to other feature selection methods via five classifiers, the SNRGES yields better classification performance. On available training examples from four microarray databases, we indicate that SNRGES is capable of achieving better accuracies
than previous studies, and is able to effectively remove redundant features and obtain efficient sets for sample classification purposes.
The Permanent Residential Housing: Geographic Information System-Based Evaluation Considering the Legislation
Authors: Bartoněk Dalibor , Dermeková Stanislava
Published: May 2017

The paper deals with the conception of multi-criteria analysis geographic information system (GIS). The set of criteria has great influence on the whole project in GIS. This fact is described in chapter “materials and methods” where a new model is discussed. In these model
is included influence of legislative which restrict the set of criteria. The selected criteria have also determine the input dataset. It leads to proper and optimal selecting of set of input data in GIS. The advantage is the optimization of input data and selects the best variant in combination
with strategies in spatial decision making. The article proposes the evaluation process which is user oriented and consists of several multi-criteria methods. In this paper the authors proposed a mathematical model which includes input data containing hypothesis of the stakeholders (input
criteria) and output data representing proposed variants for different solutions. Experimental results are focused on GIS based evaluation of permanent residential housing. As main method of multi-criterial analysis is used sensitive analysis. A team of experts and stakeholders sett importance
of the various criteria and thus determine the values of weights for their quantification. These parameters are determined in the model as the main criteria for strategic planning in the real estate engineering. The weights are also numerically quantified using different methods of decision
theory. Selected and restricted criteria (by legislative) determine the set of spatial analytical functions. Spatial analyses create an important part of this method. Spatial analyses serve as an attractive cartographic presentation of the project to users appearing in the real estate market
using static and of interactive maps. Graphically and numerically multi-criteria analyses are presented as the final result which report analyzing the effectiveness of various factors. These factors affect the real estate market and the price of real estate. From an economic point of view,
it is possible to determine these factors by the supply and demand for a particular type of property. The proposed method is a new approach to comprehensive evaluation criteria for the purposes of the real estate market. The existing MCDA methods are integrated into one unit and evaluated
through an optimal variant.

(0, ∞) with arbitrary positive initials x−1, x0 to be bounded, α-convergent and the equilibrium point to be globally asymptotically stable. Finally we present the condition for which every positive solution converges to a prime two
periodic solution. Our results coincide with that known for the cases M(x) = x in Ref. [3] and M(x) = xk, where k ∈ (0, ∞) in Ref. [7]. We have given the solution of open problem proposed in Ref. [7] about the existence
of the positive solution which eventually alternates above and below equilibrium and converges to the equilibrium point. Some numerical examples with figures will be given to show our results.
Center Clamped Forward Converter for High Current Applications
Authors: Dheeraj Alagu , Rajini V
Published: May 2017

High current applications like Microprocessors, Fuel cells, Electric Hybrid Vehicles, Solar Cells etc., use interleaved isolated buck derived converter. Interleaving of converters for such high current applications converters is done to achieve reduced input capacitor ripple voltages,
output capacitor ripple current cancellation and reduced peak currents of output inductors. Generally, interleaving requires a higher number of transformers through which distributed magnetics can be achieved. i.e., one bulky transformer can be replaced with low power profile transformers.
The performance of forward converter depends on core resetting of the main transformer. The core’s magnetizing energy is recycled by resetting it. In the absence of core reset, the current builds up at each switching cycle, saturates the core, causes reverse recovery problem in the diode
and the active clamp will no longer in zero voltage state during turn on of the main switch. The transformer secondary output is used as a gating pulse for Synchronous Rectifiers. These have very low forward drop which are most suitable for high current applications. Among various used clamping
methods, the transformer core is optimized effectively by Active center clamp reset approach. The proposed method results in less number of switches and clamping capacitor, and lower cost compared to conventional forward converter. Reduction in voltage stress without losing duty-cycle ratio
is also achieved by means of a series-parallel connected switch structure with Self Driven Synchronous Rectifiers. The proposed center clamp converter overcomes the Maximum Duty cycle limitation of 50%. This paper mainly focuses on active center clamp forward converter and is also compared
with Active Positive Negative clamping techniques.
Theoretical modelling and experimental analysis of the vertical stiffness of a convoluted air spring including the effect of the stiffness of the bellows
Authors: Chen Jun-Jie , Yin Zhi-Hong , Rakheja Subhash , He Jiang-Hua , Guo Kong-Hui
Published: May 2017

A new refined model including a model of the bellows to describe the vertical stiffness of a convoluted air spring is developed. The new model of a convoluted air spring incorporates the structural parameters including the effective area, the rate of change in the effective area, the effective volume, the rate of change in the effective volume and the stiffness of the bellows. Analytical models of the structural parameters of a convoluted air spring are established using a geometrical analysis approach. Two convoluted air springs (type 1B5002 and type 2B5281) are designed and manufactured for testing purposes. An experimental set-up is designed in order to carry out identification of the structural parameters and to test the vertical static stiffness and the vertical dynamic stiffness. The analytical models of the structural parameters are validated by experiments, which provide good design guidance and improvement in the convoluted air spring at the design stage. Tests on the vertical static stiffness and the dynamic stiffness indicate that the stiffness of the bellows should be considered; furthermore, the stiffness of the bellows exhibits amplitude-dependent chacteristics and frequency-dependent characteristics. In a different approach from the previous studies, a model of the bellows is developed in this paper and is composed of a smooth friction model and a fractional derivative Zener model in parallel to represent the viscoelastic properties of the bellows. It is concluded that the simulation results of the proposed new model are in good agreement with the experimental data. The new refined model may be an effective tool for predicting the mechanical behaviours of a convoluted air spring before a prototype is constructed. The proposed refined model can also be practically utilized as a guide for designing the parameters and for matching the air suspension of the vehicle.

Published: May 2017

Natural samples of the substituted basic Cu(II) chloride series, Cu4–xMx2+(OH)6Cl2(M = Zn, Ni, or Mg) were investigated by single-crystal X-ray diffraction in order to elucidate compositional boundaries associated with paratacamite and its congeners. The compositional ranges examined are Cu3.65Zn0.35(OH)6Cl2 – Cu3.36Zn0.64(OH)6Cl2 and Cu3.61Ni0.39(OH)6Cl2 – Cu3.13Ni0.87(OH)6Cl2, along with a single Mg-bearing phase. The majority of samples studied have trigonal symmetry (R3̄m) analogous to that of herbertsmithite (Zn) and gillardite (Ni), with a ≈ 6.8, c ≈ 14.0 Å. Crystallographic variations for these samples caused by composition are compared with both published and new data for the R3̄m sub-cell of paratacamite, paratacamite-(Mg) and paratacamite-(Ni). The observed trends suggest that the composition of end-members associated with the paratacamite congeners depend upon the nature of the substituting cation.
3D angle decomposition for elastic reverse time migration
Authors: Duan Yuting , Sava Paul
Published: May 2017

We have developed three approaches for 3D angle decomposition using elastic reverse time migration. The first approach uses time- and space-lag common-image point gathers computed from elastic wavefields. This method facilitates computing angle gathers at sparse and possibly irregularly distributed points in the image. The second approach transforms extended time-lag images to the angle domain using slant stacks along 4D surfaces, instead of using slant stacks along 2D straight lines. The third approach transforms space-lag common-image gathers to the angle domain. The three proposed methods solve a system of equations that handles dipping reflectors, and they yield angle gathers that are more accurate compared with those obtained via alternative existing methods. We have developed our methods using 2D and 3D synthetic and field data examples and found that they provide accurate opening and azimuth angles and they can handle steeply dipping reflectors and converted wave modes.
Gender, Generation, and Women's Independence Organizing in Puerto Rico
Authors: Materson Lisa G.
Published: May 2017

This article examines the activism of three women of different generations—Emilia Rodríguez Sotero, Baldramina Sotero Cervoni, and Isabel Rosado Morales—in the movement for Puerto Rico's independence in the twentieth century to demonstrate the sheer breadth of some of the strategies undergirding that struggle. It uses oral history to reveal the otherwise unseen interactions and emotional support that extended across political generations of women in Puerto Rico. The article argues that women independence activists followed a dialogic practice that contributed to the movement's endurance. They spoke across political generations and looked to the biographies of women they knew well to style their own activism and navigate profound institutional and cultural barriers against independence organizing. Such intergenerational exchange defies an easy inheritance model and instead presents a genealogy of women's activism that was dialectical in bridging each generation's experiences at the intersection of political work and private life.
CarpeteoRedux
Authors: LeBrón Marisol
Published: May 2017

This article examines the practice of “carpeteo,” or politicized police surveillance and targeted harassment, during the 2010 and 2011 student strikes at the University of Puerto Rico (UPR). LeBrón argues that police and security forces engaged in tactics that deeply resonated, for many students, with historical forms of repression experienced by political dissidents in Puerto Rico. Drawing from interviews with student activists, the author details how students culled from popular knowledge about the violent, politicized policing experienced by Puerto Rican radical movements in order to position themselves within a genealogy of repression and resistance on the island. Rather than understanding their experience as unique or unprecedented, UPR students instead situated their movement, and the policing of their movement, within historical struggles against inequality and colonial rule in Puerto Rico.
Stable carbon isotopes in breath reveal fast incorporation rates and seasonally variable but rapid fat turnover in the common shrew (Sorex araneus)
Authors: Keicher Lara , O'Mara M. Teague , Voigt Christian C. , Dechmann Dina K. N.
Published: May 2017

Small non-migratory mammals with Northern distribution ranges apply a variety of behavioural and physiological wintering strategies. A rare energy saving strategy is Dehnel's phenomenon, involving a reduction and later regrowth of the body, several organs and parts of the skeleton in red-toothed shrews (Soricidae). The size extremes coincide with major life stages. Yet, the physiological consequences for the shrews' metabolism remain poorly understood. In keeping with the energetic limitations that may induce the size changes, we hypothesized that metabolic incorporation rates should remain the same across the shrews' lifetime. In contrast, fat turnover rates should be faster in smaller subadults than in large juveniles and regrown adults, as the metabolic activity of fat tissue increases in winter individuals. Measuring changes in exhaled carbon stable isotopes we found that the baseline diet of shrews changed across the season. A diet switch experiment showed that incorporation rates were consistently rapid (t50=38.2±21.1-69.3±53.5 min) and did not change between seasons. As predicted, fat turnover rates were faster in size-reduced subadults (t50=2.1±1.3 h) compared to larger juveniles (t50=5.5±1.7 h) and regrown adults (t50=5.0±4.4 h). In all three age/size classes all body fat was turned over after 9-24 h. These results show that high levels of nutrient uptake are independent of body size, whereas fat turnover rates are negatively correlated to body size. Thus, the shrews might be under higher pressure to save energy in winter and this may have supported the evolution of Dehnel's phenomenon.

Published: May 2017

About the Zingiber zerumbet little is known about its cut flower postharvest and market, despite its high ornamental potential. The inflorescences, which resemble a compact cone, emerge from the base of the plants and start with green color changing to red with the age. This study objective was to characterize floral stem of ornamental ginger in two cultivate conditions and to evaluate the longevity of those submitted to post-harvest treatments. Flower stems were harvest from clumps cultivated under full sun and partial shade area, and were submitted to the postharvest treatments: complete flower immersion in tap water (CFI) or only the base stem immersion (BSI). The flower stems harvested from clumps at partial shade presented higher fresh weight, length and diameter of the inflorescences compared to flower stems harvested from clumps at full sun area. The flower stem bracts cultivated in full sun area changed the color from green to red 10.69 and 11.94 days after BSI and CFI postharvest treatments, and the vase life were 22.94 and 28.19 days, respectively. Flower stem harvest in partial shade area change the color only after 18.94 and 18.43 days and the vase life durability was 27.56 and 31.81, respectively. The complete immersion of the flower stem increase the vase life durability in 5.25 and 4.25 days compared to flowers kept with the stem base immersed only, in flower stems harvested from clumps cultivated in full sun area and partial shade area, respectively. Flower stems harvested from clumps cultivated in partial shade area and completely immerse in tap water during 3 hours increase the vase life durability in 8.87 days compared to flowers harvested from clumps cultivated in full sun area and base immersed only.

Math Manipulatives for Students with Severe Intellectual Disability: A Survey of Special Education Teachers
Authors: Jimenez Bree Ann , Stanger Carol
Published: May 2017

A survey was conducted with 86 teachers across 10 states regarding their students’ ease of use of physical manipulatives incorporated with implementing evidence-based early numeracy instruction. The majority of respondents indicated significant student accessibility barriers. Specifically, 75% of respondents had students with tactile defensiveness or lack of gross motor skills; 85% had students with weak to no fine motor skills; and 83% had students who lost track of the math objectives while manipulating materials, making the use of manipulatives difficult or impossible. Ninety-four percent of respondents agreed or strongly agreed that the use of manipulatives are valuable for students to gain early numeracy concepts; however almost half indicated difficulty using them within math instruction. Finally, respondents overwhelmingly noted their student’s engaged with technology (e.g., iPad, Smart Board) to support learning. Overall survey results and need for future research, including the use of virtual manipulatives are discussed.

Extracting the symmetry of the human face from digital photographs
Authors: Renero-C Francisco-J. , Romero-H Reimer-A. , Peregrina-B Hayde
Published: May 2017

By defining a midline and selecting six pairs of the landmarks of the human face on digital photographs, we extracted the symmetry of the human face by means of digital techniques. As a first approach to the symmetry of the human face, the distances and the tilts from the midline, between similar landmarks, were computed and averaged, respectively. The procrustes analysis and the histogram of oriented gradients (HOG), applied on patches on the six pairs of the landmarks of the human face, were used as a second approach to the symmetry of the human face. To have a better estimation of the symmetry of the whole human face, the photographs in grayscale and color were cut on pairs of strips, equally spaced from the midline, and then the strips were compared by the HOG feature extractor. The symmetry of the human face was extracted from 89 photographs of human faces (37 females and 52 males, ages 28.67±6.65 and 35.65±12.2 years, respectively). The HOG feature extractor applied on strips for the photographs in color and grayscale provided more confident values for the symmetry of the human face, which was well correlated with the assigned value by the photographers and physiotherapists. Also, an experiment was performed to evaluate the attractiveness as a function of the human face symmetry; thus, two groups of men and women were asked to sort digital photographs of women and men according to the attractiveness of women/men on the photographs. The results show that the most selected digital photographs were those with the highest symmetry scores.
Design considerations for patient-specific surgical templates for total hip arthroplasty with respect to acetabular cartilage
Authors: Mueller Samuel , Ahmad Intsar , Kraemer Manuel , Utz Michael , Gaa Johannes , Kahrs Lüder A. , Ortmaier Tobias
Published: May 2017

Patient-specific instruments (PSIs) are clinically used to support the surgeon during a planned intervention. The planning is typically done based on volumetric image data from medical imaging systems, e.g. computed tomography (CT). The PSI uses the known surface structure of a bone for orientation during the intervention. Some surfaces of human bone are covered with a layer of cartilage which is hardly visible in clinically applied CT-imaging. This experimental study investigates ten different PSI designs and their effect to the overall accuracy when neglecting the cartilage in the design process. Therefore, a model of an acetabulum is used to simulate the use case of PSI in total hip arthroplasty. The concept of the different designs is to create structural elasticities in the PSI to avoid shifting of the whole instrument and rather have a small part of it deformed by cartilage. A needle array structure, for instance, should also be able to oust or penetrate remaining soft tissue in the acetabulum.

A Chiusine urn whose provenance can be traced back to the Firmin-Didot collection was recently brought to the attention of the authors and appears to be previously unknown in any corpora or other publications of Etruscan inscriptions, despite its remarkable condition. This urn came from excavations undertaken by Alessandro François between 1852 and 1857, and the family name appears to be of Umbrian origin.
Using RNA-Seq for Genomic Scaffold Placement, Correcting Assemblies, and Genetic Map Creation in a CommonBrassica rapaMapping Population
Authors: Markelz R J Cody , Covington Michael F , Brock Marcus T , Devisetty Upendra K , Kliebenstein Daniel J , Weinig Cynthia , Maloof Julin N
Published: May 2017

Brassica rapa is a model species for agronomic, ecological, evolutionary, and translational studies. Here, we describe high-density SNP discovery and genetic map construction for a B. rapa recombinant inbred line (RIL) population derived from field collected RNA sequencing (RNA-Seq) data. This high-density genotype data enables the detection and correction of putative genome misassemblies and accurate assignment of scaffold sequences to their likely genomic locations. These assembly improvements represent 7.1–8.0% of the annotated B. rapa genome. We demonstrate how using this new resource leads to a significant improvement for QTL analysis over the current low-density genetic map. Improvements are achieved by the increased mapping resolution and by having known genomic coordinates to anchor the markers for candidate gene discovery. These new molecular resources and improvements in the genome annotation will benefit the Brassicaceae genomics community and may help guide other communities in fine-tuning genome annotations.
Behavioral Deficits Following Withdrawal from Chronic Ethanol Are Influenced by SLO Channel Function in Caenorhabditis elegans
Authors: Scott Luisa L , Davis Scott J , Yen Rachel C , Ordemann Greg J , Nordquist Sarah K , Bannai Deepthi , Pierce Jonathan T
Published: May 2017

Symptoms of withdrawal from chronic alcohol use are a driving force for relapse in alcohol dependence. Thus, uncovering molecular targets to lessen their severity is key to breaking the cycle of dependence. Using the nematode Caenorhabditis elegans, we tested whether one highly conserved ethanol target, the large-conductance, calcium-activated potassium channel (known as the BK channel or Slo1), modulates ethanol withdrawal. Consistent with a previous report, we found that C. elegans displays withdrawal-related behavioral impairments after cessation of chronic ethanol exposure. We found that the degree of impairment is exacerbated in worms lacking the worm BK channel, SLO-1, and is reduced by selective rescue of this channel in the nervous system. Enhanced SLO-1 function, via gain-of-function mutation or overexpression, also dramatically reduced behavioral impairment during withdrawal. Consistent with these results, we found that chronic ethanol exposure decreased SLO-1 expression in a subset of neurons. In addition, we found that the function of a distinct, conserved Slo family channel, SLO-2, showed an inverse relationship to withdrawal behavior, and this influence depended on SLO-1 function. Together, our findings show that modulation of either Slo family ion channel bidirectionally regulates withdrawal behaviors in worm, supporting further exploration of the Slo family as targets for normalizing behaviors during alcohol withdrawal.

Pada perikanan tuna, tuna neritik merupakan kelompok ikan yang dominan tertangkap pada perikanan pantai, termasuk perikanan skala kecil dan bersifat artisanal. Penangkapan ikan tuna neritik di perairan Palabuhanratu yang semakin intensif setiap tahunnya tanpa didasari pengelolaan yang tepat, diduga akan mengakibatkan terjadinya penurunan stok sumberdaya ikan. Penelitian ini bertujuan untuk menganalisa keberlanjutan spesies neritik tuna menggunakan analisis produktivitas dan suseptibilitas / Productivity and Susceptibility Analysis (PSA). Penelitian ini dilaksanakan dari Februari hingga Mei 2016 di perairan Palabuhanratu. Hasil penelitian menunjukan nilai kerentanan tuna neritik berturut-turut untuk ikan tenggiri 1.25, tongkol krai 1.37, tongkol abu-abu 0.91, tongkol komo 1.49, dan tongkol lisong 1.41. Hal ini menunjukan bahwa tingkat kerentanan ikan tuna neritik terhadap overfishing saat ini masih rendah karena nilainya masih dibawah 1,8, sehingga aktivitas penangkapan masih dapat ditingkatkan terutama untuk ikan tenggiri dan tongkol abu-abu yang memiliki kerentanan terendah.Neritic tuna are mainly caught by coastal fisheries, including small scale fisheries and artisanal fisheries. The continuous absence of proper management for neritic tuna, will result in a decline in the stock of fish. This study aims to analyze the sustainability of neritic tuna species by analyzing the productivity and susceptibility (PSA). The research was conducted from February to May 2016 in Palabuhanratu waters. Vulnerability indexs for narrow-barred Spanish mackerel (Scomberomorus commerson) 1.25, frigate tuna (Auxis thazard) 1.37, longtail tuna (Thunnus tonggol) 0.91, kawakawa (Euthynnus affinis) 1.49, and bullet tuna (Auxis rochei) 1.41. These vulnerability indexs shows that level of vulnerability for overfishing for neritic tuna is low because the vulnerability index still below the maximum limit vulnerability index (1.8), fishing activities can still be increased, particularly for narrowbarred Spanish mackerel and longtail tuna that has the lowest vurnerability.

Synovial sarcoma (SS) represents about 10% of all soft tissue sarcomas. It is believed that its origin would be found in cells that are related neither to ultrastructural nor to histological features of the synovial tissue. Head and neck is very rarely affected, with the lower extremities being most frequent. Complete resection with or without radiotherapy and chemotherapy is currently considered the best available therapy. This time we present the case of a patient with SS located in the infratemporal fossa, its diagnosis, treatment and evolution. According to our knowledge it is the first reported case in South America.

Laser microstructuring of the surface can be used for improving tribological properties of materials. Thistrend suggests a laser treatment to create on the materials surface microstructures with spatial selectivity ofphysical-mechanical properties, such as microhardness, friction factor, etc. The microstructuring of the externalsurface of gas-dynamic compactions is perspective. To increase the capacity of the practical use of it is expedientto enhanced functionality through the use of laser microstructuring of the more common laser systems with pulsedurations in the millisecond range. A method of surfaces modification of silicon carbide details by lasertreatment for improving their tribological properties has been developed. A material structure in the heat-affectedzone after laser microstructuring has been studied. Evaluated the morphological changes of the treated surfaceafter a repetitively pulsed laser exposure. It was established that the pulse-periodic laser exposure leads to theformation on the polished surface of the silicon carbide parts recesses are round to oval. Along with theformation of acyclic microrelief occurs modifying surface structure details. Under laser exposure on the surfaceof the ceramic material is a decomposition of silicon carbide and graphite to form a solid solution of carbon insilicon. Supposed to carry out the study of the tribological properties of the resulting structures.

Introduction: Vegetables and fruit are an essential part of a healthy and balanced diet. It has been shown that regular consumption of fruit and vegetables can reduce the risk of chronic diseases. However, in the past ͜8 years fruit and vegetable consumption among Polish youth has significantly decreased.Materials and methods: Patients involved in the project were participants of the Woodstock Festival Poland 2014 During three days of the festival, 615 young adults (18–35 years) were enrolled in the study. The study participants had to fill in a questionnaire that included questions about the frequency of fruit and vegetable consumption, portion sizes, and knowledge of the recommended daily intake. We also measured basic anthropometric parameters.Results: The data from our study showed that 97,6% of respondents consumed fewer than ͘ servings of vegetables and fruit. In addition 39% of them ate 2 or fewer vegetable servings per day. We found that men ate significantly less fruit and fewer vegetables than women (p < 0.05). Additionally, almost 75 % of men responded that proper consumption of fruit and vegetables should be at the level of 4–5 servings, and only 22,3% of them said that the proper level is ͘4–5servings.Conclusions: We need to keep in mind that only clear information about vegetables and fruit, as well as highlighting the importance of the principles of nutrition, can give effective results in the future. It also appears that nutritional education should be conducted not only at the early stages of development but also in adolescents.

Dewatering optimization with in-line and real-time measurement of polymer: results from full-scale treatment plants
Authors: Örmeci Banu , DiMassimo Richard
Published: May 2017

Full-scale testing was carried out at two wastewater treatment plants to determine whether residual polymer concentration, measured by filtrate and centrate absorbance at 191 nm, can be used to identify the optimum polymer dose and achieve in-line and real-time dewatering optimization. The first plant uses high speed centrifuges and the second plant uses belt filter presses for dewatering. During the testing, the polymer dose incrementally increased to cover the under-dose, optimum dose and over-dose polymer ranges, and the centrate/filtrate absorbance at 191 nm, turbidity and cake solids were measured. The results showed that absorbance measurements at 191 nm exhibited a parabolic shaped curve with increasing polymer dose, where the minimum absorbance corresponded to the optimum polymer dose. The method can directly measure the residual polymer concentration and determine the optimum polymer dose accordingly, and is planned to be used in the development of a dewatering automation system in the future.
