Integrating booster chlorination and operational interventions in water distribution systems
Authors: Nono Denis , Basupi Innocent , Odirile Phillimon T. , Parida Bhagabat P. 
Published: May 2018

Abstract
Booster chlorination reduces the risks associated with conventional disinfection such as high chlorine residuals near water treatment plants and low chlorine residuals at remote parts of water distribution systems (WDSs). Network operational interventions have a significant influence on water age and chlorine decay in WDSs. In this study, an integrated booster chlorination method is developed to obtain optimal designs that reduce the risks associated with conventional disinfection in WDSs. The method integrates booster chlorination with network operational interventions to reduce water age and improve chlorine residuals in WDSs. A multi-objective booster optimisation problem is formulated based on risks associated with chlorine disinfection and solved using a non-dominated sorting genetic algorithm (NSGA-II) and the EPANET hydraulic and water quality solver. The proposed methodology was tested in the Phakalane WDS in Botswana. The integrated booster disinfection method significantly improves chlorine residuals in a WDSs with lower mass and cost of chlorine than conventional disinfection. Furthermore, the study indicates that integrated booster chlorination designs are influenced by changes in network conditions such as water demand and chlorine decay coefficients. Therefore, periodic monitoring of these parameters is required to ensure that the acceptable performance of chlorine boosters in WDSs is maintained.

Published: May 2018

Abstract
Rivers provide innumerable ecosystem services to mankind. However, anthropogenic activities have inflicted a host of pressures to the riverine ecosystems. Climate change is also one of the human induced consequences which is of serious concern. A number of studies have predicted devastating effects of climate change. In the Indian context, where a river such as the Ganga is already suffering from industrial and municipal waste disposal, unhygienic rituals, and other activities, effects of climate change may further aggravate the situation. Climate change will not only result in disasters, but effects on water quality, biodiversity, and other ecological processes also cannot be denied. In this paper, an attempt has been made to evaluate the effects of climatic change on the dynamics of River Ganga. The study focuses on the impacts on fundamental ecological processes, river water quality, effect on species composition, and hydropower potential etc. The paper also discusses management aspects and research needs for rejuvenation of the River Ganga.

Background:Cystic echinococcosis/ hydatidosis is one of the most important parasitic zoonoses worldwide. Usually, surgery is used for the treatment of active cysts. Due to the risk of cyst rupture during surgery, a protoscolicidal agent is usually injected into the cyst before surgery to prevent secondary cyst formation in case of cyst rupture. Due to the side effects of chemical protoscolicidal agents attempts have been focused on herbal medicine. In this regard, Allium sativum has already been used; however, the protoscolicidal effect of Allium hirtifolium from Allium family has not been investigated, so far.Objective:The present study was conducted in order to assess the protoscolicidal effect of methanolic extract of Allium hirtifolium in different concentrations, temperature and exposure times. Cetrimide as a positive control and DMSO as a negative control were also used in this study.Methods:The viability of protoscoleces was determined by 0.1% eosin staining method.Results:The protoscolicidal effect of Allium hirtifolium on protoscoleces was as follows: The mean percent and standard deviation (SD) of protoscolicidal activity of 50 mg/ml concentration of Allium hirtifolium extract in room temperature at 10, 20, 30, 40 and 50 minutes of exposure was 5.88±2.39, 8.59±4.54, 11.82±5.81, 12.31±6.16and 16.96±8.42 respectively; while at 37°C it was 9.10±5.01, 11.52±7.36, 18.64±4.36, 27.07±6.57 and 38.15±12.80, respectively.Conclusion:In conclusion, although Allium hirtifolium from Allium family is similar to Allium sativum; the protoscolicidal effect of its methanolic extract is not similar and less than A. sativum extract.

Authors: Guerrini Daniel , Piconi Larissa , Sturion Leonardo , Da Mata Ednei 
Published: May 2018

Este artigo analisa o ingresso de estudantes nos cursos da Universidade Tecnológica Federal do Paraná, Câmpus Londrina, no ano de 2015, com base nas mudanças implementadas pela Lei de Cotas (Lei Federal nº 12.711/2012). Essa lei tornou obrigatória a reserva de vagas para alunos egressos de escolas públicas, de baixa renda e autodeclarados pretos, pardos ou indígenas (PPI) nas instituições federais de ensino superior e técnico, constituindo-se como medida compensatória diante dos efeitos dos privilégios sociais e da desigualdade nas condições de acesso ao ensino superior. Investiga o preenchimento das vagas reservadas na instituição mencionada para identificar em que medida as ações afirmativas têm cumprido os propósitos para os quais foram pensadas. Foram coletadas as notas de entrada dos alunos em 2015, buscando suas medidas de centralidade estatística, comparando cotistas com não cotistas e os diferentes cursos entre si. Analisa, ainda, a relação entre reserva de vaga e seu preenchimento nas quatro categorias de cotistas e no grupo de não cotistas. Observa-se que o prestígio dos cursos é um fator relevante para o aumento das medianas das notas de entrada dos estudantes e também que a categoria de cotas para pessoas de baixa renda tem colocado entraves para o preenchimento de suas vagas.

Tomat beef merupakan salah satu jenis tomat yang mempunyai nilai ekonomis tinggi. Salah satu teknik budidaya yang dapat diguna-kan untuk meningkatkan produksi tanaman tomat yaitu perbaikan media tanam dengan penambahan arang sekam dan mengatur jumlah cabang produksi. Percobaan bertujuan untuk mempelajari berbagai dosis arang sekam dan jumlah cabang produksi yang baik untuk pertumbuhan, hasil dan kualitas tomat. Penelitian dilaksanakan di Laboratorium Kultur Terkendali, Fakultas Pertanian, Univer-sitas Padjadjaran di Jatinangor. Rancangan percobaan menggunakan Rancangan Petak Terbagi dengan tiga ulangan. Petak utama adalah penambahan arang sekam dengan empat taraf : 0%, 10%, 20%, 30% dan anak petak adalah jumlah cabang produksi dengan dua taraf : satu cabang dan dua cabang produksi. Hasil pengamatan menunjukkan tidak terdapat hubungan yang saling mempengaruhi antara penambahan arang sekam dan jumlah cabang produksi pada semua variabel pengamatan. Perlakuan penambahan 0% dan 20% arang sekam tanaman lebih tinggi dibanding perlakuan 30% arang sekam, namun jumlah daun, ukuran daun dan diameter batang sama, sehingga tidak berpengaruh terhadap hasil. Penggunaan dua cabang produksi menghasilkan jumlah daun lebih banyak tapi ukuran daun lebih kecil dibanding dengan satu cabang produksi, sehingga hasilnya sama.
