Integration of high-rate DAF technology within a municipal biofiltration plant for the treatment and thickening of backwash wastewaters
Authors: Clement Roche , Gildas Manic , Isabelle Lacroix 
Published: December 2018

Abstract
Industrial full-scale application of high-rate dissolved air floatation (DAF) in the municipal wastewater treatment plant (WWTP) of Grenoble (France) has highlighted outstanding performance results leading to new design-to-cost perspectives. The integration of DAF technology to treat the returns from the backwash waters of submerged biological aerated filters (BAF) (nitrification stage) has demonstrated removal efficiencies that allow further room for global process optimization. The results obtained on nitrifying BAF backwash water showed a DAF outlet water concentration of less than 25 mg.L−1 of total suspended solids at 25 m.h−1, with only polymer conditioning. Such high clarification performance allows leveraging of valuable cost optimization of global process design integration. Direct discharge from DAF's outlet into the receiving body can be implemented. Hydraulic and solid return loads can therefore be significantly reduced at the inlet of the WWTP. Moreover, floated sludge extracted from the DAF units achieved 4.4% dryness on average. The high thickening operational performance of this DAF technology is able to produce sludge directly compatible with anaerobic digestion. These full-scale results demonstrate that Suez's GreenDAF™-BWW technology in such application can leverage new rooms for design improvement for BAF treatment and total cost optimization of both the mainstream water treatment line and sludge line.

Published: December 2018

AbstractThe aim of this study was application of multivariate statistical techniques – e.g., hierarchical cluster analysis (HCA), principal component analysis (PCA) and discriminant analysis (DA) – to analyse significant sources affecting water quality in Deepor Beel. Laboratory analyses for 20 water quality parameters were carried out on samples collected from 23 monitoring stations. HCA was used on the raw data, categorising the 23 sampling locations into three clusters, i.e., sites of relatively high (HP), moderate (MP) and low pollution (LP), based on water quality similarities at the sampling locations. The HCA results were then used to carry out PCA, yielding different principal components (PCs) and providing information about the respective sites' pollution factors/sources. The PCA for HP sites resulted in the identification of six PCs accounting for more than 84% of the total cumulative variance. Similarly, the PCA for LP and MP sites resulted in two and five PCs, respectively, each accounting for 100% of total cumulative variance. Finally, the raw dataset was subjected to DA. Four parameters, i.e., BOD5, COD, TSS and SO42− were shown to account for large spatial variations in the wetland's water quality and exert the most influence.
Properties of Oils From Plantain Pseudostem Biotransformed Using Crude Local Enzyme Sources: A Comparison of Poultry Feed Oil
Authors: Uchenna Amadi P. , Charity Ogunka-Nnoka U. , Bene Abbey 
Published: December 2018

Background:
Plantain Pseudostem (PPS) wastes were biotransformed by applying Simultaneous
Saccharification and Fermentation (SSF) using excised snail digestive juice and yeast
slurry, and their oil properties compared with oils from commercially sold poultry feeds (PF). Patents
suggesting the inclusion of certain additives (US20090226558A1), spices (US5741508A), cysteamine
(US4711897A), and dextrin (US6326051B1) in animal diets are regarded as expensive,
thus, requiring cheaper and readily available sources of growth.

Methods:
The analysis of their free radical scavenging potentials was carried by spectrophotometry,
while fatty acids, volatile fatty acids, essentials oils, and phytosterols were determined by
chromatography.

Results:
After biotransformation, the melting point, specific gravity, acid, and peroxide values of
the oils from SSF-PPS were significantly lower than those of PF, and showed elevations of C6:0-
C18:1(trans-9) fatty acids, palmitic, stearic, γ-Linolenic, α-linolenic, behenic, and lignoceric acids.
Camphene, β-phelandrene, eugenol, β-elemene, bicyclogermacrene, guaiol, tetradecanoic acid, and
hexadecanoic acid levels decreased when PPS was biotransformed. Lactic (1575.75 mg/100g), acetic
(1234.26 mg/100g), propionic (845.74 mg/100g), and n-butyric (68.56 mg/100g) acids were the
predominant Volatile Fatty Acids (VFAs) in the SSF-PPS oils, which were higher than those found
in the PF oil while PF oil contained higher campesterol, Stigmasterol, and 5-avesmasterol. The 2,2-
azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS), 1,1-diphenyl-2- picrylhydrazyl (DPPH),
superoxide, and nitric oxide radical scavenging potentials of PPS oil at high concentrations after
biotransformation were equivalent to the standards and the PF oil.

Conclusion:
his study has shown that biotransformation involving snail digestive juice and yeasts
extensively improves the oil qualities of agricultural residues sufficient enough for poultry nutrition.
Assessment of data fusion oriented on data mining approaches to enhance precision agriculture practices aimed at increase of Durum Wheat (Triticum turgidum L. var. durum) yield

Published: December 2018

In 2050, world population will reach a total of 9 billion inhabitants and their food demand have to be satisfied. Durum wheat (Triticum turgidum L. var. durum) is one of the most important food crop and its consumption is increasing worldwide. Productivity growth in agriculture and profitable returns are strongly influenced by investment in research and development, where Precision Agriculture (PA) represents an innovative way to manage farms by introducing the Information and Communication Technology (ICT) into the production process. It is known that farms activities produce large amounts of data. Today ICT allows, with electronic and software systems, to collect and transfer automatically these data, thus increasing yields and profits. In this direction significant data are processed from agricultural production, and retrieved to extract useful information important to increase the knowledge base. Data from multiple data sources can be processed by a Data Fusion (DF) approach able to combine multiple data sources into an unique database system. Raw data are transformed into useful information, thus DF improves pattern recognition, analysis of growth factors, and relationship between crops and environments. Data Fusion is synonym of Data Integration, Sensor Fusion, and Image Fusion. By means of Data Mining (DM) it is possible to extract useful information from data of the production processes thus providing new outputs concerning product quality and product “health status”. The following literature take into account the DF and DM techniques applied to Precision Agriculture (PA) and to cultivation inputs (water, nitrogen, etc.) management. We report also last advances of DF and DM in modern agriculture and in precision durum wheat production.
IMPACT OF DRUG EXPOSURE DEFINITIONS ON OBSERVED ASSOCIATIONS IN PHARMACOEPIDEMIOLOGY RESEARCH
Authors: Eskin M , Simpson SH , Eurich DT 
Published: December 2018

BACKGROUND - A variety of methods used to define exposure in pharmacoepidemiologic studies. Although each method has known biases, the relative effect of these biases on an observed association has not been fully examined.
OBJECTIVE - To explore the influence of different exposure definitions on estimates, using the association between metformin and all-cause mortality as a proto-typical model.
METHODS - New users of oral anti-hyperglycemic drugs were identified using administrative health databases from Alberta, Canada between 1998 and 2010. Drug exposure was described using definitions that are commonly used in observational studies. All analyses included the same covariates of age, gender, and a comorbidity score, and subjects not exposed to metformin served as the reference group. The measure of association was assessed using a Cox Proportional Hazards model for cohort studies and conditional logistic regression for case-control studies.
RESULTS – We identified 64,293 new oral anti-hyperglycemic drugs users; mean age 68.9 years, 33,131 (52%) males, and 24,745 (39%) deaths during a mean follow-up of 6 years. In adjusted models, the association between metformin and mortality ranged from 0.23 (95% CI 0.22-0.25) to 0.92 (95% CI 0.88-0.95) reduction. Most metformin exposure definitions, however, provided estimates in the 0.6-0.8 reduction range, aligning with the results of previous observational studies.
CONCLUSIONS – The variety of exposure definitions tested in this analysis produced a wide range of associations between metformin and mortality risk. Therefore, pharmacoepidemiological studies should include sensitivity analyses using at least two exposure definitions with complementary risks of bias to improve the validity of study results.

Published: December 2018

Limbah medis sangat penting untuk dikelola secara benar, hal ini mengingat limbah medis termasuk ke dalam kategori limbah berbahaya dan beracun. Sebagian limbah medis termasuk kedalam kategori limbah berbahaya dan sebagian lagi termasuk kategori infeksius. Berkaitan dengan masalah pengelolaan limbah RSUD Raden Mattaher Jambi, kementerian lingkungan hidup memberikan label hitam pada tahun 2014 artinya dalam pengelolaan limbahnya sangat buruk dan hal itu dapat berdampak pengenaan sanksi administrasi yang akan diterima oleh RSUD Raden Mattaher Jambi. Menurut Pasal 198 Peraturan Pemerintah Nomor 101 Tahun 2014 Tentang Pengelolaan Limbah Bahan Berbahaya Dan Beracun ”Setiap Orang yang menghasilkan Limbah B3, Pengumpul Limbah B3, Pengangkut Limbah B3, Pemanfaat Limbah B3, Pengolah Limbah B3, dan/atau Penimbun Limbah B3 yang melakukan Pencemaran Lingkungan Hidup dan/atau Perusakan Lingkungan Hidup wajib melaksanakan: a. Penanggulangan Pencemaran Lingkungan Hidup dan/atau Kerusakan Lingkungan Hidup; dan b. Pemulihan Fungsi Lingkungan Hidup. Dengan adanya peraturan perundang- undangan tersebut seharusnya pengelolaan limbah rumah sakit harus berpedoman pada peraturan yang berlaku. apabila hal tersebut tidak diterapkan maka pemerintah berhak mengenakan sanksi administrasi terhadap masalah tersebut baik itu berupa pencabutan izin sementara ataupun bentuk lain yang telah ditetapkan.

Investor Reaction to Disclosure of Past Performance and Future Plans
Authors: Emett Scott A. 
Published: December 2018

ABSTRACT
I examine how and why current-period performance shapes investors' evaluations of future-oriented disclosures. Three experiments provide evidence that a firm's current-period performance shapes investors' beliefs about the appropriateness of managerial optimism, which, in turn, affects investors' evaluation of firms that focus on either challenges or opportunities in future-oriented disclosures. When a firm is performing poorly, investors believe that managers can best achieve success by being optimistic about the future and, therefore, invest more when the firm focuses on opportunities rather than challenges in future-oriented disclosures. When a firm is performing well, on the other hand, investors believe that managers can best achieve success by being realistic about the future and, therefore, invest more when the firm focuses on challenges rather than opportunities.
Adhesive precoated bracket systems and operator coated bracket systems: Is there any difference? A systematic review and meta-analysis
Authors: Alakttash Ahmed Mohamed , Fawzi Mohamed , Bearn David 
Published: December 2018

ABSTRACT

Objectives:
To investigate whether adhesive precoated brackets (APC) are more efficient than operator-coated brackets (OPC) regarding failure rate, bonding time, patient experience, gingival health, plaque accumulation, and white spot lesion formation.

Materials and Methods:
Five online databases: Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, PubMed, MEDLINE, and Web of Science were searched for potential eligible randomized controlled trials (RCTs). A Google Scholar and gray literature search was undertaken. References of included studies were screened for potential eligible studies. Results were collated from each database and modified Cochrane data extraction forms were completed. Quality assessment was performed using Cochrane RoB 2.0 tool for RCTs.

Results:
Five studies met the inclusion criteria. All reported failure rates using metal brackets for both APC and OPC systems except one that compared clear APC to clear OPC. Three studies reported bonding time differences between the bracket systems. A quantitative synthesis of four studies reporting failure and three reporting bonding time was undertaken. Random effect meta-analysis determined there were no statistically significant differences in bond failures between bracket systems with an odds ratio of 0.890 (P = .808). Bonding time showed a statistically significant (P = .01) but not clinically significant shorter bonding time with OPC. There was insufficient evidence to assess plaque accumulation, gingival health, and either patient or operator experience.

Conclusions:
There is no superiority of either bracket system regarding failure rate. OPC are statistically significantly superior over APC in bonding time although this is most likely not clinically significant.

Based on the results of this experience, we emphasize that students with visual impairments need didactic resources and specific curricular adaptations so that they can participate actively in the construction of their learning and for this, the approaches of the History of Science are essential in this process.Keywords : Inclusive; blind; history of chemistry.
O essencialismo na classificação de Lineu e a repercussão dessa controvérsia na Biologia
Authors: Klepka Verônica , Corazza Maria Julia 
Published: December 2018

ResumoNos últimos dois séculos, Lineu e toda taxonomia tradicional têm sido acusados de exercerem uma prática essencialista, pautada na descrição de tipos. Ernest Mayr foi um dos que contribuíram para disseminar essas ideias que passaram a ser consideradas como verdades na Biologia. Entretanto, nas últimas duas décadas, historiadores e filósofos da Biologia contestaram esse argumento oferecendo novas análises que corrigem o anacronismo efetuado na história das classificações biológicas. Neste artigo, nosso objetivo é argumentar, com o auxílio de obras originais de Lineu e fontes secundárias provenientes de estudiosos da vida e do trabalho do sueco, bem como de historiadores e filósofos da Biologia, por que a classificação biológica lineana não é fundamentada no essencialismo platônico ou aristotélico. Observamos que as obras e o contexto de Lineu foram mal interpretados, que suas influências na ciência eram totalmente contrárias à lógica escolástica e que, apesar de usar termos como essência, gênero e espécie em suas obras, não há qualquer relação com a lógica aristotélica. Palavras-chave: Carl von Linné; Classificação dos Seres Vivos; História da Ciência. AbstractIn the last two centuries, Linnaeus and all traditional taxonomy has been accused of exercising an essentialist practice, based on the description of types. Ernst Mayr was one of those who contributed to disseminate these ideas that came to be considered as truths in Biology. However, in the last two decades historians and philosophers of biology have contested this argument by offering new analyzes that correct the anachronism in the history of biological classifications. In this article, our objective is to argue, with the help of original works by Linnaeus and secondary sources from scholars of the life and work of the Swedish, as well as historians and philosophers of Biology, because the linear biological classification is not based on essentialism Platonic or Aristotelian. We note that Linnaeus' works and context were misinterpreted, that his influences on science were wholly contrary to scholastic logic, and that in spite of using terms like essence, genus, and species in his works, he had no connection with Aristotelian logic.

Published: December 2018

Abstract
The growth of seven exotic true fir (Abies) species and native Abies alba have been compared in three provenance trials in the Czech Republic, at the relatively advanced ages of 44, 38, and 35 years respectively. A clear differentiation is observable between the species. The closely related species group of A. alba and A. cephalonica appears rather heterogeneous in its phenotypic behavior. A. alba provenances show superiority, but also a high differentiation. Productivity of provenances of A. cephalonica fall behind A. alba; however A. cilicica and A. pinsapo provenances have shown total mortality. The high potential of A. grandis is confirmed by outstanding growth; provenances from the coastal plain in Washington State performed best. A. procera grows slower than A. grandis, but still faster than A. alba provenances. Health risks, extreme ecologic distances of transfer, trend shifts of growth rate, and rank change with age are uncertainties that require necessary caution when selecting provenances for importation. In recent years, public and institutional perceptions concerning the introduction of non-native tree species and provenances has shifted, and the practice is no longer seen as necessarily inappropriate.
Adapting Hellwig’s method for selecting concomitant variables under a certain growth curve model
Authors: Wesołowska-Janczarek Mirosława , Różańska-Boczula Monika 
Published: December 2018

Summary
This paper presents an application of Hellwig’s method for selecting concomitant variables under a growth curve model, where the values of the concomitant variables change over time and are the same for all experimental units. The authors present a simple adaptation of the growth curve model to the multiple regression model for which Hellwig’s method applies. The theoretical considerations are applied to the selection of significant concomitant variables for raspberry fruiting.
