Composting of aged reed bed biosolids for beneficial reuse: a case study in New Jersey, USA
No full textReed beds with Phragmites australis (common reed) have been utilized to decrease the water, nutrient and volatile solids content of sewage sludge. An efficient disposal/reuse option was sought for reed bed biosolids accumulated over a 15 year period at a wastewater treatment facility in New Jersey, USA. The study facility had 14 reed beds, each with 1000 wet tons capacity, which were full, and so the solids needed to be removed. Because P. australis is considered an invasive species in New Jersey and several other states in the United States, disposal or reuse of solids containing this plant is regulated. Composting was examined as a potential treatment for destroying the plant’s reproductive rhizomes. The high temperatures achieved during composting were also tested to determine if regulatory criteria for pathogen reduction could be met, making the composted product suitable for unrestricted land application. Preliminary studies indicated the sludge had stabilized to the point where self-heating did not occur. Among the carbon amendments tested in the laboratory to stimulate compositing activity, Phragmites above ground biomass was determined to be most suitable. In a field test, Phragmites above ground biomass was mixed with reed bed biosolids at a 1:2 (w/w) ratio. The temperatures achieved resulted in complete mortality of Phragmites rhizomes. In laboratory tests, rhizomes placed in a drying oven at 50ºC for 24 hours, or 55ºC for 12 hours, showed 100% plant mortality. However, under field conditions pile temperatures could not be maintained long enough for the sludge to meet the USEPA 503 biosolids time-temperature pathogen rule requirements for unrestricted land application, even though sample fecal coliform counts did meet regulatory limits.Peer reviewed

Characterization of Wood Mulch and Leachate/Runoff from Three Wood Recycling Facilities
No full textLarge-scale open storage of wood mulch is common practice at wood recycling facilities. During rain and snow melt, leachate with soluble compounds and suspended particles is released from mulch stockpiles. The objective of this study was to determine the quality of leachate/runoff from wood recycling facilities to evaluate its potential to contaminate receiving waterbodies. Wood mulch (n = 30) and leachate/runoff (n = 26) samples were collected over 1.5 years from three wood recycling facilities in New Jersey, USA. Differences by site were found (p < 0.05) for most of the 21 constituents tested in the solid wood mulch samples. Biochemical oxygen demand (range <20 – 3000 mg/L), chemical oxygen demand (134 - 6000 mg/L) and total suspended solids (69 - 401 mg/L) median concentrations of the leachate/runoff samples were comparable to those of untreated domestic wastewater. Total Kjeldahl N, total P and fecal coliform median values were slightly lower than typical wastewater values. Dose-response studies with leachate/runoff samples using zebrafish (Danio rerio) embryos showed that mortality and developmental defects typically did not occur even at the highest concentration tested, indicating low toxicity, although delayed development did occur. Based on this study, leachate/runoff from wood recycling facilities should not be released to surface waters as it is a potential source of organic contamination and low levels of nutrients. A study in which runoff from a controlled drainage area containing wood mulch of known properties is monitored would allow for better assessment of the potential impact of stormwater runoff from wood recycling facilities.Peer reviewe
Distopía, futurismo y maquinización en Mosko-Strom de Rosa Arciniega
No full textEl següent article es proposa realitzar una lectura d’una de les novel·les més representatives de Rosa Arciniega durant la seva estada a Espanya de 1928 a 1936, Mosko-Strom. El torbellino de las grandes metrópolis (1933). Mitjantçant una anàlisi de l’obra es reflexionarà sobre la posició crítica que desenvolupa l’autora respecte al procés de mecanització que experimenta occident durant les primeres dècades del segle XX i on el futurisme, com a ideologia, hi juga un paper fonamental. Per realitzar aquesta crítica, Arciniega el·labora una distopia en la que presenta eles efectes negatius d’aquesta mecanització. La part més interessant del text és que no només fa referència a aquest estat negatiu de les coses, sino que també planteja una sol·lucions als problemes que exposa. En aquest sentit, Mosko- Strom es constitueix en una novel·la de tesis.The following article offers a reading of Mosko-Strom: The Whirlwind of the Great Metropolises (1933), one of Rosa Arciniega’s most representative novels written during her stay in Spain from 1928 to 1936. Through the analysis of her work, we will reflect on the critical position that the author develops regarding the mechanization process experienced by the West in the first decades of the twentieth century, a process in which Futurism, as an ideology, plays a very important role. To carry out this criticism, Arciniega elaborates a dystopia in which she presents the negative effects of said mechanization. The interesting thing about the text is that it not only refers to this negative state of affairs, but also proposes a solution to solve it. In this sense, Mosko-Strom constitutes a roman à these (thesis novel).El siguiente artículo se propone realizar una lectura de una de las novelas más representativas de Rosa Arciniega en su estancia en España desde 1928 a 1936, Mosko-Strom.

Implementation of the Teamwork Skills Inventory Among Adolescents
No full textabstract: Individual and group accountability is an important part of productive group work. However, classroom evaluation of teamwork often relies on top-down assessment of group product by the teacher. Other methods include averaging group grades, group discussions, evaluative essays and random selection and application of one member's grade to the entire team. In contrast, the Teamwork Skills Inventory (TSI) developed by Strom and Strom provides assessment of individual conduct and contributions as observed by peers. The instrument also affords students with the opportunity to judge their own performance. Team members are responsible for their own behavior and skill development but are not held accountable for the actions taken by others. The TSI provides criteria for productive teamwork skills and behaviors. Students know in advance the criteria by which they and their teammates will judge each other's behavior skills. In turn, students have the opportunity to practice self-evaluation as they apply the same criteria to assess their own conduct. Self-evaluation compared with peer-evaluation provides support for confidence in behavioral strengths and can guide goal setting in areas where skills are weak and need adjustment. The TSI gives teachers an insider's view of group dynamics: the obstacles and benefits groups may encounter. Since team members have the vantage point of close interaction with peers they are more likely to know how individuals affect the thinking of others in a group. This frees teachers from the difficult task of judging group dynamics. TSI results can guide teachers in developing lessons that address the needs of individuals and groups. Data derived from the TSI can help schools provide for the needs of subgroups, such as special education and gifted classes. It can also help schools detect in-service needs for faculty and provide schools with a method of community accountability for use with cooperative learning methods and social skill achievement.Dissertation/ThesisM.A. Educational Psychology 201
<i>Surealis Yogya</i> and other surrealist moments in Indonesia in the 20th century
No full textThis entry explores the history of Surrealist work in Indonesia in the later twentieth and early twenty-first centuries, with an emphasis on the Yogya surealis group of Yogyakarta. In so doing, it raises critical challenges to historical narratives of Surrealism that exclude developments outside of Paris and the interwar years. It proposes a conception of Indonesian Surrealism as defined by a “cluster of qualities,” which may be alternately resonant with other variants of international Surrealism, such as an embrace of ambiguity and juxtaposition, or specific to the cultural and political history of contemporary Indonesia, such as its responses to the situation of post-colonial dynamics and its explorations of metaphysical spirituality

Diagnostic exome sequencing in early-onset Parkinson's disease confirms VPS13C as a rare cause of autosomal-recessive Parkinson's disease.
No full textParkinson's disease (PD) is a genetically heterogeneous disorder and new putative disease genes are discovered constantly. Therefore, whole-exome sequencing could be an efficient approach to genetic testing in PD. To evaluate its performance in early-onset sporadic PD, we performed diagnostic exome sequencing in 80 individuals with manifestation of PD symptoms at age 40 or earlier and a negative family history of PD. Variants in validated and candidate disease genes and risk factors for PD and atypical Parkinson syndromes were annotated, followed by further analysis for selected variants. We detected pathogenic variants in Mendelian genes in 6.25% of cases and high-impact risk factor variants in GBA in 5% of cases, resulting in overall maximum diagnostic yield of 11.25%. One individual was compound heterozygous for variants affecting canonical splice sites in VPS13C, confirming the causal role of protein-truncating variants in this gene linked to autosomal-recessive early-onset PD. Despite the low diagnostic yield of exome sequencing in sporadic early-onset PD, the confirmation of the recently discovered VPS13C gene highlights its advantage over using predefined gene panels
