The Ability of Water Hyacinth (Eichhornia crasipes Mart.) and Water Lettuce (Pistia stratiotes Linn.) for Reducing Pollutants in Batik Wastewater

2021

Batik produced by craftsmen is categorized as a small and medium industry. The problem of Batik production is less attention to the environment because the craftsmen lived in the middle of a residential area that has inexperience. One of less attention to the environment is no treatment of wastewater that reaches up to 95 % (61.9 L each cloth). Thus it polluted the river. This research aimed to treat the wastewater of Batik production by using phytoremediation. In this study, phytoremediation was carried out in three tanks in series using Eichhornia crassipes and Pistia stratiotes which are abundant in Indonesia. The treated wastewater was evaluated for its ammonia and chromium (Cr). The re…

Uskonveljet ahdingossa : saksanjuutalaisten näkemyksiä venäjänjuutalaisten tilanteesta vuosina 1905-1906 sanomalehdissä Allgemeine Zeitung des Judent…

2015

Tutkielmassani tarkastelin saksanjuutalaisten näkemyksiä venäjänjuutalaisten tilanteesta vuosina 1905 ja 1906. Lähdeaineisto koostui kahdessa saksanjuutalaisessa sanomalehdessä vuosina 1905 ja 1906 julkaistuista pääkirjoituksista, viikkokatsauksista, mielipidekirjoituksista, artikkeleista ja uutisteksteistä. Toinen sanomalehdistä oli linjaltaan varsin neutraali Allgemeine Zeitung des Judentums, jota julkaistiin Berliinissä. Toinen sanomalehti oli linjaltaan sionistinen Frankfurter Israelitisches Familienblatt, jota julkaistiin Frankfurt am Mainissa. Tutkimuskysymyksiä työssä oli kaksi, joista ensimmäinen koski sitä, miten saksanjuutalaiset käsittivät sen, mitä Venäjällä oli tapahtumassa juu…

Koulukodit esiripun takana : koulukodit ammattilehtien artikkeleissa ja tieteellisissä julkaisuissa

2010

Koulukodit ovat olleet osana suomalaista lastensuojelujärjestelmää jo 1820-luvulta lähtien, mutta pitkästä historiasta huolimatta niistä tiedetään varsin vähän ja usein ihmisten mielikuvat koulukodeista ovat syntyneet niihin liittyneen negatiivisen julkisuuden myötä. 1960-luvulla koulukoteja alettiin arvostella voimakkaasti. Koulukodit ovat kuitenkin säilyttäneet asemansa kaikkein vaikeahoitoisimpien lasten kuntouttajina, mutta kritiikki ei ole poistunut. Yhtenä koulukotien kehittymisen esteenä on pidetty koulukotitutkimusten vähäistä määrää ja tutkimustiedon puuttuessa koulukotitoiminta on ollut helppo leimata sisäpiirin puuhasteluksi, josta puuttuvat yhteiset kehityslinjat ja tutkimustiet…

Lipodepsipeptides from Pseudomonas syringae are partially proteolyzed and are not absorbed by humans: An in vitro study

2008

There are some concerns about the use of Pseudomonas-based products as biocontrol agents because of the hemolytic activity shown by their metabolites. The effects of Pseudomonas lipodepsipeptides (LDPs) on mammals via ingestion and the LDP degradation during the digestion and intestinal permeability have not been evaluated. In this research, the susceptibility of different LDPs to degradation was assayed with enzymatic gastrointestinal digestion, and intestinal permeability to LDPs was investigated in an in vitro system based on an intestinal cell layer system. Results demonstrated that trypsin and chymotrypsin hydrolyze up to 50% of the various LDPs, and that proteolysis was further increa…

Increasing the drying efficiency of cylinder drying

2011

This PhD Thesis concentrates on paper drying: first on the drying rate in a cylinder covered with fabric, enhanced using hot air impingement through the fabric, and its potential effects on paper quality, and second, on the heat transfer rate from hot steam to paper through the cylinder shell. Cylinder drying is a drying method where a heated surface in contact with paper causes water removal from the latter by evaporation. Impingement through the fabric of hot air has been suggested to cause increase in the water removal and drying of paper. Increase in the drying rate by impingement of hot air was confirmed by laboratory tests and by simulations. In laboratory tests the increase in the dr…

Analysis of a viscoelastic phase separation model

2020

A new model for viscoelastic phase separation is proposed, based on a systematically derived conservative two-fluid model. Dissipative effects are included by phenomenological viscoelastic terms. By construction, the model is consistent with the second law of thermodynamics, and we study well-posedness of the model, i.e., existence of weak solutions, a weak-strong uniqueness principle, and stability with respect to perturbations, which are proven by means of relative energy estimates. A good qualitative agreement with mesoscopic simulations is observed in numerical tests.

Assessing the case of Dengue in Argentina 2009: discrimination and fear

2010

After almost a decade, the re-appearance of Dengue in Argentina caused panic and fears. Unlike Bolivia, Brazil and Paraguay where policies of preventions have been followed, the future of dengue is uncertain for Argentina; this paper does not have any political affiliation but emphasizes the role that mass media play in the coverage of epidemics. The question as to whether a newspaper or mass media corporation should maintain a minimum of objectivity is too complex to be resolved in this short article. However, we have so far set forth a model which will help other researchers to interpret topics of this nature in the future. In moments of disorder, uncertainty or disaster, societies experi…

Data from: Multi-modal defenses in aphids offer redundant protection and increased costs likely impeding a protective mutualism

2018

1.The pea aphid, Acyrthosiphon pisum, maintains extreme variation in resistance to its most common parasitoid wasp enemy, Aphidius ervi, which is sourced from two known mechanisms: protective bacterial symbionts, most commonly Hamiltonella defensa, or endogenously encoded defenses. We have recently found that individual aphids may employ each defense individually, occasionally both defenses together, or neither. 2.In field populations, Hamiltonella-infected aphids are found at low to moderate frequencies and while less is known about the frequency of resistant genotypes, they show up less often than susceptible genotypes in field collections. To better understand these patterns, we sought t…

Craniopharyngiomas in Children - Experience of Consecutive 152 Operated Cases

2020

Context Craniopharyngiomas (CPH) are benign tumors, rarely encountered in children, representing 5-6% of all intracranial tumors. Objective This study aimed to analyze the surgical management and quality of life in a series of CPH pediatric cases. Design This was a multicenter study performed over a 25-year period (1994 - 2019) in Bucharest. Subjects and methods 152 children (0-17 years old) were treated for CPH. Preoperative manifestations were intracranial hypertension, endocrine dysfunction, visual impairment, ataxia, intellectual performance decrease. Results Considering all surgical approaches used, we advocate for pterional approach to best fit in CPH. We achieved gross-total removal …
